North Dakota 1953 cold case solved — arrest shocks community

…

The distance between Castleton and Wheatland was just over 15 miles, normally taking 25 to 30 minutes in winter night conditions.

Next, police asked the family about stops Thomas usually made during evening drives, a small gas station near Enderland Junction, a late night diner beside the tracks, and a telegraph station where he sometimes sent reports to the Fargo Bismar line when issues arose.

All these locations were checked on the morning of January 19th.

The gas station attendant had not seen Thomas that night.

The diner recorded low customer volume and no match to the couple’s description.

The telegraph station had no record from Thomas’s technician number.

For Evelyn, police checked possible post dance stops such as a friend’s house, the town bookstore, or the teacher’s boarding house.

No one had seen her after leaving the hall.

The absence of any reasonable stops led police to conclude that the couple’s timeline extended at most to the moment they left the hall.

After that, there was a complete void that could not be reconstructed.

After cross-referencing all statements, authorities concluded there was no basis to believe they had voluntarily left the area given their work schedules, personal responsibilities, and communication habits all indicated plans to return home that night.

Failing to appear at their residences, and not making contact for over 24 hours was considered a serious red flag under 1953 standards.

From this assessment, police officially opened an investigation classifying the case as high-risisk missing persons and began systematically checking the entire Castleton Wheatland route.

On the morning of January 19th, 1953, after completing the timeline and ruling out voluntary departure, Castleton police, in coordination with support from Cass County, immediately deployed search teams along the full length of Highway 10 between Casseldon and Wheatland.

Treating it as the primary route to check first due to its logical fit with Thomas Brandt’s habits.

The search was divided into small groups, each assigned a specific segment to ensure no detail was missed, especially in windy, heavily snow-covered conditions where evidence could be quickly erased.

They began at the southern exit of Castleton, where Thomas’s Plymouth was believed to have passed right after leaving the dance and proceeded westward.

First, police carefully examined both snow-filled ditches along the road because in winter, vehicles could slide off the road and be buried without obvious signs.

Searchers used shovels, probes, and high-powered flashlights to probe deep drifts, but found no metal objects, glass fragments, or any trace of a crashed vehicle.

Next, they focused on known accident black spots, including two sharp curbs before the intersection with Farm Route 12 in the area around the Culver Bridge over Maple River.

These locations were prioritized because vehicles that lost control could easily plunge down embankments or become trapped under thick snow.

However, despite harsh weather, the road surfer showed no skid marks, brake marks, or any disturbance consistent with a vehicle traveling the previous night at the Maple River Bridge.

They found the snow layer intact, undisturbed by tire tracks or footprints, meaning no vehicle had left the bridge in an unusual direction during the night of January 17 or morning of January 18.

They also checked beneath the bridge where vehicles sometimes fell without leaving surface evidence, but the river was fully frozen with no cracks or depressions.

The search then moved to elevated sections where vehicles could roll or slide and be covered by snow.

Walker spread out along the road, checking gaps between guardrails and using probes on deep snow.

Another group examined low shoulders and roadside brush where metal or glass fragments from collisions might remain, but the survey found nothing unusual.

Police also had a technician simulate the damage a Plymouth might cause to snow or roadside structures in a serious accident, but the simulated results did not match the actual condition of Highway 10.

To be thorough, the search expanded several hundred ft beyond the shoulders, especially in areas where strong winds created unusual snow drifts that could cause vehicles to veer off.

Even with the expanded radius, no tire tracks newer than 24 hours were found, except for those of routine daily traffic.

By noon on January 19th, the team had covered nearly 70% of Highway 10 and reported no evidence suggesting Thomas and Evelyn had been in an accident on the road.

To ensure completeness, they finished the remaining portion that afternoon, but the situation remained unchanged.

No debris, no skid marks, no drag marks, no unusual snow compression, and no sign of an abandoned vehicle.

The complete absence of any accident indicators along the entire Highway 10 forced police to take the necessary next step.

Rule out disappearance due to a traffic accident on the main route.

This meant the most logical and probable hypothesis based on local experience no longer fit the facts, compelling authorities to prepare for more complex possibilities to continue the investigation.

After ruling out an accident along the entire Highway 10, Castleton police and Cass County support shifted to expanding the search to secondary roads and farm routes connecting Casselton, Weedland, and surrounding areas.

These were often poorly maintained dirt roads lightly traveled in winter and possible locations where a vehicle could have left the main route unnoticed.

To determine the exact areas to cover, police used 1953 topographic maps from the land management office showing dirt roads, tractor paths, private farm access lanes, and temporary agricultural routes.

The map was spread out at the Castleton Station and divided into three main zones.

Southern roads paralleling the railroad from Castleton, northern roads from Wheatland, leading to abandoned 1940s farms, and dirt roads between the two towns mainly used for crop transport.

First search teams moved to dirt roads branching south from Highway 10 where two large farms in an abandoned barn stood.

They examined road edges, windb blown snow banks, and terrain prone to tire slippage.

However, recorded tire tracks were old and matched agricultural trucks, not the Plymouth Thomas drove.

Next, they turned to northern routes from Wheatland.

This area featured many trails leading deep into fields directly exposed to cold western plains winds that blew snow into thick layers obscuring vehicle traces.

Teams walked in clusters spaced tens of meters apart to closely observe snow ruts and depressions.

They noted some slight depressions possibly caused by animals or natural snow settling, but no signs of motorized traffic during the suspected time frame.

During the sweep, Glee marked several suspicious points, mainly sections partially buried by deep snow or leading to rarely used areas.

The most notable being a trail east of Weedland with a compressed snow track several meters long.

Closer inspection determined it was a snow sled track from a nearby farmer unrelated to the disappearance.

Other areas such as collapsed barn entrances, old farmwood piles, and trails near small creeks are also checked, but yielded similar results.

No fresh tire marks, no metal objects, no glass fragments, no footprints, and no evidence indicating Thomas and Evelyn had passed through.

Searchers also examined accidentprone dirt sections, sinkies, slippery slopes, or snow covered deep holes, but still found no Plymouth or characteristic signs of a vehicle leaving the road.

After more than a day of sweeping the entire secondary road system between Castleton and Wheatland, the team concluded its report.

No vehicle, no victims, and no signs they had left the main route via side paths.

The lack of any fresh traces left police with the interim conclusion that the couple had not encountered trouble on back roads, further narrowing early hypotheses about off-road accidents.

With no leads from main or secondary roads, the investigation was forced to shift toward other directions where the cause of disappearance might no longer involve random accidents.

While search efforts gradually narrowed possibilities after comprehensive checks of main and secondary roads yielded no useful traces, Castleton police received new information on the morning of January 20th, 1953, when a farmer living east of Weedland voluntarily came to the station to report that on the night of January 17, roughly coinciding with when Thomas and Evelyn left the Castleton Hall, he had heard a high-speed vehicle engine and arguing voices carrying across the field.

According to the witness, shortly after 11,7 pm while checking livestock before closing up, the northwest wind carried clear sounds, a sudden revving engine, followed by what sounded like two people arguing loudly, then abrupt silence.

In the open plains of North Dakota, sounds often traveled farther on windy nights, so the witness’s account was deemed consistent with field conditions.

Police immediately conducted a more detailed interview to determine the direction and approximate distance of the sound.

The witness pointed southeast of his farm where a system of trails ran parallel to Maple River and intersected a rarely used dirt road.

Cross referencing with a 1953 topographic map, police realized the described area lay outside the zones searched the previous day partly because it was large private land without clear access and partly because the trail did not appear on standard traffic maps but only on agricultural survey maps.

This made the area a new subject for evaluation.

The witness also stated he saw no headlights, only heard sounds, so the distance could range from several hundred meters to over a mile.

Using the map, police delineated a search test.

Based on the wind direction recorded at the Fargo weather station on the night of January 17th, northwest to southeast, strong enough to carry sound in a relatively straight path.

They then drew a wide arc on the investigation map encompassing trails leading toward Maple Ridge Creek, marking several low-lying topographic points where sound could have echoed.

After analyzing the sound direction, police added a new search branch to the overall investigation diagram.

The dirt trail running from the old Castro family farm to the sparse woods bordering Maple Ridge.

This route was almost unused in winter except by a few scattered households.

The search team was redeployed to this area that same afternoon of January 20.

Deep snow made identifying traces difficult, but the team still checked segment by segment using measuring tools to identify possible tire compressions.

The terrain was relatively complex.

Some trails were completely buried.

Others wind scoured into unusual deep ruts.

However, near the intersection with the trail toward Maple Ridge, searchers discovered a lightly disturbed snow area, possibly caused by engine heat melting surface snow into patchy patches before refreezing.

Though not conclusive evidence of a vehicle stopping there, it stood out compared to surrounding areas.

Police logged the location in their report and marked it on the investigation map as a point requiring deeper inspection.

During the search, they also probed two snow rats leading into a depression near the creek.

As these were places a vehicle could become stuck or buried.

However, except for a thin ice crust on the surface, no metal, glass, or mechanical traces indicated a vehicle had slid there.

The team continued checking suspect areas mentioned by the witness, including the gentle slope along the Maple Ridge rise, sometimes used as a shortcut by locals.

But wind hardened snow made the work difficult and collected signs remained inconclusive.

After completing the expanded search day, police noted that the witness’s statement was the first lead related to unusual activity on the night of the disappearance.

Though it provided no precise coordinates, the information about the engine noise and arguing was significant enough to be added to the investigation map as a new line of inquiry, opening the possibility that the couple had left the main route via a littleknown trail.

While the exact origin of the sound remained unidentified, delineating the corresponding area allowed police to open an additional search branch previously unconsidered, thereby expanding the investigation into a region with more complex terrain than the routes examined earlier.

On the morning of January 21, 1953, after compiling the witness statement regarding the engine noise and arguing voices on the night of the disappearance, Castleton police dispatched a dedicated search team back to the described area.

This time with the sole task of focusing on identifying signs of vehicle movement based on the terrain conditions and wind direction recorded on the night of January 17.

This area lay along the strip of land between the Kestrel Farm and the Maple Ridge Rise, a region with little traffic activity in winter due to its soft road base, heavy snow cover, and lack of maintenance.

The search team began at the point the witness identified as the direction from which the sound had carried, then expanded the search in a fan pattern to avoid missing any secondary trails that might lead to the location where the engine noise originated.

Strong winds in the preceding days had blown the snow into uneven layers, creating bumpy, difficult to observe terrain.

However, after more than an hour of sweeping, the team discovered a roughly 7 m long section of snow showing compression from tire pressure.

Although the edges of the tracks had been blurred and distorted by wind, police marked the area with wooden stakes and began taking measurements.

Using a steel tape, they measured the width of the remaining tire ruts.

The distance between the outer edges was nearly 56 in, while the depth of snow compression at the remaining points ranged from 1.

5 to 3 in.

These figures were not sufficient to immediately identify the vehicle type, but the tread pattern in force distribution indicated the ruts belong to a midsize passenger car, not an agricultural truck, tractor, or heavy vehicle, which would typically leave deeper and wider impressions.

For comparison, police referred to the list of common vehicle models in North Dakota during 1952 to 1953, including the Plymouth Cranbrook, Ford Custom Line, Chevrolet Style Line, and Dodge Coronet.

All of these had rear axle widths ranging from 54 to 58 in, meaning the newly discovered tire tracks were entirely consistent with one of the passenger cars like the one Thomas regularly used to travel between Wheatland and Castleton.

Continuing to examine the end of the tire track, the search team noted that the ruts did not head toward Wheatland as Thomas’s intended route would have required, but instead veered southeast and entirely illogical direction for returning home after the dance.

This turn meant leaving Highway 10 and heading deep into a sparsely populated area containing only a few scattered farms and trails leading toward the ridges near Maple Ridge.

Police assessed that the likelihood of these tire tracks having been made on the night of the disappearance was very high because the light snowfall on the morning of January 18 was insufficient to completely erase them.

While strong winds could blur the edges, resulting in their current appearance.

Based on the characteristics of the remaining tracks, the search team followed the ruts as far as possible.

However, only about 10 m farther, the tracks disappeared completely due to intense wind sweeping across the open edge, covering the old ruts with fresh snow.

The team attempted to use probes to detect compressed layers beneath, but could not confirm the continuation because the snow was too deep and the underlying ground had frozen solid.

Although they could not trace the full path of travel, police still noted the anomaly of the turn, there was no reasonable explanation for Thomas to drive southeast at that time, especially since the area was completely off his usual routes or any place he had reason to visit.

This raised questions about whether the change of direction was voluntary or forced into the remote area.

To strengthen the findings, the search team surveyed a 200 meter radius around the track segment to check for signs the vehicle may have stopped or become stuck.

However, all surrounding areas showed no snow pits, broken branches, or material fragments that could be linked to the Plymouth or the victim’s personal belongings.

Several other minor compression marks were noted, but measurements of size and depth determined they belong to farm vehicles moving early on the morning of January 18 and did not match the suspect track pattern.

Thus, although the witness designated area did not provide direct evidence of the victim’s presence, it did reveal an unusual tire track that did not align with the route home and matched the size of the type of vehicle Thomas drove.

This discovery allowed authorities to conclude that the victims or their vehicle had left Highway 10 in an unexplained direction, heading deep into an area served only by dirt trails directly contrary to the familiar route they should have taken.

This provided the basis for police to mark the area on the investigation map as a location requiring expanded examination, while also prompting a re-evaluation of all initial hypotheses concerning the couple’s movements on the night of their disappearance.

On the morning of January 22nd, 1953, after compiling all data from the faint tire tracks and the unusual turn documented in the witness indicated area, Castleton police in coordination with the Cass County search team expanded the sweep southeastward along the trails leading toward Maple River.

This area featured open terrain interspersed with wild grass strips along the river and low depressions easily buried by snow, requiring the team to move slowly and continuously mark each checked section.

Near midm morning while observing from a lowrise overlooking the field edge, one search team member spotted a dark object protruding slightly above the white snowits color matching the roof of Thomas Brand Plymouth.

Police approached cautiously and confirmed the vehicle was indeed the blue Plymouth described earlier by the family.

The car sat at the edge of the field about 100 meters from the Maple River Bank with its front end angled slightly southwest as though it had stopped after a short distance off the trail, but there were no signs of plunging, getting stuck, or collision.

The snow around the vehicle was relatively level with no deep rots or plowed marks indicating loss of control.

The front of the car showed no dents.

The windshield was intact, headlights unbroken, front bumper free of fresh scratches, evidence that the vehicle had not been in an accident.

Police further noted that the snow immediately beside the right side tires showed light compression, suggesting the car had been deliberately stopped rather than forced to halt due to mechanical failure.

Looking into the cabin through the windows, they observed the steering wheel in normal position.

No key in the ignition, driver’s seat not violently displaced.

All doors were locked with no signs of forced entry, and the paint surface showed no unusual scratches.

The distance from the trail to the car’s position was only about 30 m, making it plausible that the vehicle left the path either by the driver’s choice or under compulsion before coming to a stop.

However, no on-site evidence yet indicated what happened after the car stopped.

Police immediately secured the area, designating the Plymouth location as crime scene number one in the disappearance case, and reported to command for additional personnel and equipment to conduct a vehicle examination according to 1953 procedures.

Investigation team members measured distances, photographed the scene from multiple angles, and recorded the car’s orientation relative to wind conditions on the night of January 17 to determine whether it had been winddrifted or driver controlled.

The body of the car was completely cold, showing no signs of recent operation.

However, this was consistent with a multi-day disappearance timeline.

The area surrounding the vehicle was carefully searched for footprints, dropped items, or any physical evidence related to Thomas and Evelyn, but snowfall and strong winds in the preceding days had rendered the entire ground uniform, preserving no exploitable traces.

Police opened the vehicle using specialized tools after obtaining permission, noting that the interior was not seriously disturbed.

Seats in original position, documents in the glove compartment untouched, no property missing.

This ruled out initial robbery as a motive.

They also inspected pedals, floor mats, and areas near the bench seat, but no snow had adhered inside, indicating the car had been locked before bad weather set in.

External examination of the vehicle yielded no clear signals, no drag marks, blood, torn fabric, or objects indicating a struggle near the car.

The team collected surface snow layers around the vehicle in case microscopic particles were present.

Though 1953 analysis equipment was insufficient for deep processing.

Nevertheless, finding the Plymouth in an area far removed from any logical route raised many questions.

Why was the car stopped here? Who was driving at the time? What caused the victims to leave the main path? And most importantly, where did they go after the car stopped? Upon closer inspection behind the vehicle, police noted a very faint compressed snow trail extending a few meters eastward, but it was too indistinct to determine whether it was footprints or simply snow melt and refreeze due to wind conditions.

The search day’s closing report stated that no physical evidence yet clearly explained why the car was at this location or why the victims disappeared.

The vehicle served only as a marker indicating their journey ended here, but provided no answers to the key questions.

Police officially designated this as the primary crime scene of the disappearance while simultaneously determining that crime scene number.

One carried no direct clues about the whereabouts or condition of Thomas and Evelyn, forcing the investigation to shift to subsequent analysis and search steps based on remaining possibilities.

The discovery of Thomas Brance Plymouth in the field near Maple River marked a critical turning point in the investigation, compelling Castleton police to conduct a comprehensive analysis of crime scene number one to determine the most plausible scenario leading to the vehicle’s appearance in a location completely unfamiliar to the route back to Wheatland.

After compiling all collected data, including the vehicle’s position, parked attitude, intact body condition, undisturbed interior, absence of skid or brake marks, lack of collision evidence, and no direct evidence of conflict.

Police formulated three initial theoretical possibilities.

First, Thomas and Evelyn left voluntarily.

Second, the victims were involved in an accident that left no trace.

And third, they were forced off the route and compelled to stop the vehicle at this location.

To assess the feasibility of each, investigators began eliminating hypotheses based on scene characteristics and lifestyle habits provided by family, colleagues, and friends.

Regarding the first possibility, voluntary departure, police analyzed that if Thomas and Evelyn had intentionally left the area, the car would not have been left fully locked.

As people departing voluntarily typically plan further travel and do not abandon a vehicle in the middle of a field in sub-zero weather.

Additionally, there was no evidence they had taken personal belongings.

Family confirmed neither had any intention of going far and all important documents remained in the car.

Moreover, the illogical southeast turn from the trail did not correspond to any known destination of the two.

All these factors made voluntary departure implausible and it was ruled out.

For the second possibility accident, police compared the scene to common winter vehicle accident features.

long skid marks, churn snow, deep sink marks on the side of loss of control, break marks on ice, scattered glass or metal fragments, collapsed snow pits where a vehicle plunged.

However, none of these signs appeared around the Plymouth.

The car was stopped aligned with the trail direction, showed no mechanical damage, and had no skid marks.

Furthermore, if the vehicle had broken down and the victims left to seek help, they would have left footprints.

But the entire area around the car showed no traces, partly due to wind and snow, but still inconsistent with behavior of people seeking assistance in harsh weather.

This effectively eliminated the accident possibility.

With the first two hypotheses ruled out, investigators focused entirely on the third coercion.

The car stop in a remote location, the illogical turn, and the intact but abandoned vehicle without reasonable explanation were all indicators of external intervention.

Additionally, the fact that the car was locked from the outside reinforced the theory that whoever was controlling the vehicle at the time of stopping was not Thomas, or if it was Thomas, he acted under duress.

The turn toward a sparsely populated area also fit the behavior of someone wishing to avoid being seen.

Police re-examined the witness statement about hearing arguing voices and a revving engine on the night of the incident, concluding the sounds were highly likely related to the vehicle being forced off the main route.

Moreover, the faint tire track found earlier on the trail matched the width of common passenger cars of the era, including Thomas’s Benny, and mud precisely toward the location where the Plymouth was discovered.

This created a logical sequence.

The vehicle was forced off the main road, traveled along a little used trail, continued a few hundred meters, then stopped in the field near Maple River.

Analysis of the vehicle’s condition also showed no signs of struggle inside the cabin or scuffle outside, suggesting that if coercion occurred, it most likely took place before reaching this location.

Or the coercing party had full control of the situation without needing to use violence that would leave traces.

After synthesizing all elements, unusual tire tracks, illogical turn, intact vehicle, clean scene, witness statement, vehicle interior condition, location far from the route home, police concluded that the coercion hypothesis was the only one consistent with the entire body of evidence.

From the afternoon of January 22, investigators officially adopted this as the primary investigative focus, marking the shift from searching for an accident to examining the possibility of third-party intervention in the disappearance of Thomas Brandt and Evelyn Hart.

After the coercion hypothesis became the primary investigative direction, Castleton police began reviewing all individuals with direct or indirect connections to Thomas Brandt and Evelyn Hart in order to identify anyone who had both motive and opportunity to intervene in the victim’s journey on the night of January 17th, 1953.

In this list, the most prominent name and the one considered the natural suspect was Diana Mercer, Thomas’s ex-wife.

Their divorce had been finalized less than 7 months before the incident, and according to statements from Thomas’s family, as well as his friends, the post-divorce relationship was far from amicable, as the civil records might suggest.

To assess Diana’s position in the case, police collected her schedule for the days before and after the victims disappeared.

They traveled to Fargo, where Diana lived, and interviewed her neighbors and co-workers at the local sewing workshop.

According to the statements, Diana was at work on the morning and afternoon of January 17th, finishing her shift around 5T 0.

For the evening, some people said she stayed home the entire time.

While one other person vaguely recalled that Diana left the house for about an hour after dinner, but did not know where she went.

When questioned by police, Diana stated that she stayed home all evening to work on household accounts, a claim that did not fully align with the information gathered from neighbors.

When these statements were cross-cheed against the time the witness heard the engine noise and arguing voices, police noted there was no evidence confirming Diana was at home during that period, nor did anyone directly witness her presence at her residence late at night.

Additionally, given that the distance from Fargo to the Castleton Wheatland area was not overly long, it was entirely possible for her to leave home unnoticed, especially in sparsely populated neighborhoods where neighbors did not habitually monitor each other’s nighttime activities.

After gathering her schedule, police moved on to verifying Diana’s past behavior toward Thomas since personal motive is always one of the key factors in disappearances showing signs of coercion.

Thomas’s family reported that Diana had displayed tension and dissatisfaction during the final stages of their marriage, including frequent late night phone calls, suddenly showing up at Thomas’s workplace to pressure him about finances, and occasionally following him when he traveled between Fargo and Wheatland.

One of Thomas’s friends recounted that in the months leading up to the divorce, Diana had repeatedly complained that Thomas was too eager to leave the old life behind, and she was unhappy when he began seeing Evelyn.

Several handwritten letters from Diana to Thomas provided to police by the family also contained outbursts expressing anger and disappointment toward him.

Although the content did not directly threaten harm to Thomas, these strong emotional expressions were noted as elements requiring consideration.

A central question police asked was whether Diana could have been present in the Castleton Wheatland area on the night the victims disappeared.

When evaluating travel feasibility, investigators determined that the drive from Fargo to Castleton could be completed in about an hour or even less at night when roads were empty.

If Diana left Fargo around 9:10 pm, she could have reached the Castleton area close to the time the witness heard the arguing and engine revving.

This made her denial of staying home all evening even more suspicious.

Another factor police examined was her personality and behavioral history.

Although Diana had no criminal record or prior arrests, many acquaintances described her as highly emotional and prone to strong reactions when feeling abandoned or disrespected.

After the divorce, she did not hide her resentment toward Thomas, quickly rebuilding his life, especially when he appeared publicly with Evelyn at community events in Castleton.

All these elements provided sufficient grounds for police to place Diana in the priority suspect category within the context of the coercion hypothesis being the main investigative focus.

However, police still lack direct evidence linking Diana to the Plymouth crime scene or the area where the faint tire tracks were found.

Yet, in the overall picture of the investigation, her unclear whereabouts that night, inconsistent statements, and potential motive tied to her personal relationship with Thomas made Diana the first person who needed further monitoring and crossverification of information, placing Diana Mercer in the priority suspect group was not based solely on possible motive, but also because she was the only individual within the close circle of the two victims whose whereabouts on the night of January 17 could not be independently verified.

and noteworthy coincidence given that Thomas’s car was found in an unusual location with no signs of an accident.

Immediately after Diana Mercer was placed in the priority suspect category, but before any direct evidence justified stronger measures, Castleton police returned to the core of scene work, searching for traces of Thomas Brandt and Evelyn Hart in the area surrounding the Plymouth.

On January 23rd, 1953, the search team expanded the sweep radius from the vehicle’s position in concentric arcs, first 200 m, then 500 m, and finally over 1 kilometer to cover the open field, the edge of sparse woods, and the section of Maple River Bank running parallel to the area.

This was complex winter terrain, deep snow, strong winds, many riverbank sections covered by thin ice and dry brush, requiring close coordination between foot teams and those using manual probes.

The main objective was to detect any signs showing in which direction the victims might have left the vehicle, or to determine whether any evidence related to them was present nearby.

Police began by examining the area east of the car, where a slightly depressed strip of land was more likely to retain traces than deeper depressions swept by wind.

However, any potential compressions or depressions had been covered by fresh snow, making it nearly impossible to distinguish human footprints from natural phenomena.

The search team then moved to the southern edge of the sparse woods, where scattered fur trees created small windbreaks.

Here, snow was less windscoured, increasing the chance of preserving footprints or dropped objects.

Yet, after more than two hours of checking each tree base and depression, searchers found no evidence, such as torn fabric, personal papers, jewelry, or items that could be linked to Thomas and Evelyn.

A few snow depressions were noted, but all appear to be from wildlife and lacked human footprint characteristics.

From the woods edge, the team shifted to the Maple River Bank, where terrain was relatively hazardous due to unstable river ice.

Without modern equipment such as sonar or ice penetrating devices available at the time, the team could only walk along the bank, observing interruptions in the ice surface, looking for cracks or signs of heavy objects falling through that the river ice remained intact with no recorded collapses, cracks, or unusual warping.

Some lowbrush sections of the bank were carefully checked, especially where snow had built up in layered drifts, but no signs indicated human movement around the time of the disappearance.

On the west side of the vehicle, searchers swept an area thick with dry grass where snow tended to cling and form thicker patches than on open ground.

This was considered a potential spot for footprints or dropped evidence during movement.

Nonetheless, all findings were only wind disturbed snow and uneven melt freeze patterns.

To ensure nothing was missed, police repeated the search vertically, following the entire path leading to Maple River, checking every small rise, clump of trees, and windblown snow banks.

They also used manual drag hooks to probe deep snow covered areas, but found only rocks, broken branches, and thin ice layers underneath nothing related to the disappearance.

By late afternoon, the team intensified the search north of the vehicle where a wide flat clearing with little tree cover might retain traces due to natural snow compression.

However, the area was completely empty.

The snow surface was smooth and showed no compressions indicating anyone had passed through after the night of January 17.

From the results obtained, the search team reconvened at crime scene number one and concluded that there were no bodies, no large items of evidence such as clothing fragments, purses, wallets, identification papers, and no physical signs of struggle or dragging.

The lack of any detectable traces led police to conclude that if Thomas and Evelyn had left the vehicle, they did not leave marks clear enough to survive two nights of strong wind and fresh snow.

From a scene analysis perspective, this opened two possibilities.

Either the victims left the vehicle in a way that avoided leaving easily recognizable traces, or they never left the area for some as yet undetermined reason.

At the end of the first expanded search day, police officially recorded the 1 km radius around the vehicle provided no physical clues about the victim’s presence or direction of movement.

The wooded area and Maple River Bank yielded no direct evidence related to their whereabouts and no major items of evidence were found across the entire zone.

Although the collected data were not groundbreaking, they played an important role.

They confirmed that crime scene number one was not the site of overt violent activity and ruled out the possibility that bodies had been left nearby.

This forced investigators to continue evaluating other feasible directions based on the remaining indirect indicators.

Although the expanded search around crime scene number one produced no major discoveries of bodies or direct clues about Thomas and Evelyn’s direction of movement, the investigative team continued meticulously checking every small sub area within the marked zone, aiming to collect any scattered items that might serve as clues in later analysis phases.

On the morning of January 24th, 1953, while re-examining the southern woods edge, one search team member found a small dark piece of fabric caught under dry grass protruding above the snow surface.

The fabric fragment was only the size of two fingertips, frayed at the edges, and appeared to have been exposed to weather for several days, but lacked any features sufficient to determine whether it came from men’s or women’s clothing.

When the area around this spot was further checked, police found no additional fabric pieces, making its origin difficult to establish.

However, because the location fell within the search perimeter tied to the disappearance, the fragment was sealed according to 1953 evidence procedures and its exact position noted for the record.

Also that morning, the team re-examined the western riverbank area where snow was deeply compressed, but had shown no clear traces in previous days.

There, a faint footprint was discovered at the edge of a gently sloping strip of ground.

The print was not intact, only the toe area, and part of one side remained visible, and snow cover had erased the entire sole pattern.

The spacing between this print and nearby snow depressions did not form a sequence sufficient to determine direction of travel or number of people.

When measured, the print was about 3 and 1/2 in wide, with the remaining length only about 5 in due to damage to the heel portion.

Based on these measurements, police could only conclude it was an adult’s footprint, but could not determine gender, shoe size, or time of impression because it could not be established whether the print was recent or pre-existing, the evidence was recorded as reference only and held no conclusive value at this stage.

By afternoon, while sweeping the wild grass area near the northern rise, where wind often swirled and exposed light objects, one search team member found a torn scrap of paper half buried under snow.

The paper fragment was small, palmsized, with writing almost completely blurred by moisture.

A few remaining inkstrokes were visible, but too faint to read.

There was no identifying information, no signature, no numbers, no useful traces.

The paper sample was sealed to prevent further damage.

But police noted that with 1953 analysis technology, they could not recover the writing or scientifically determined the paper’s origin.

The three items of evidence of fabric fragment, a faint footprint and a torn paper scrap, although not providing a breakthrough, were entered into the disappearance case evidence log, particularly because the entire area around the Plymouth had yielded almost nothing else.

Collecting such small scattered items reflected investigative methods under the technical limitations of the era.

Any object not clearly part of the natural environment could potentially become a clue in the future if analysis technology advanced or if new evidence emerged for comparison.

Police also followed proper storage protocol, placing each item in a separately sealed wax-sealed envelope clearly marked with date, time, collector’s name, weather conditions, and discovery location.

In the day’s final notes, investigators emphasized that these items could not yet prove the presence or movement direction of Thomas and Evelyn, but because they were found within the vicinity of crime scene number.

One, they needed to be carefully preserved in case later information or evidence could connect them.

The fabric fragment received particular attention because its color and material might allow identification if either victim had worn similar clothing on the night of disappearance.

In detail, not yet.

Fully confirmed by family.

The faint footprint and torn paper scrap were classified as low reliability evidence, but could become significant if additional matching data surfaced in the future.

At the close of operations on January 24, the official investigation log recorded the expanded area around crime scene number.

One yielded no large evidence or signs of bodies, but three small items were collected as reference material.

Due to the technical limitations of 1953, they could not be deeply analyzed, but they were archived in the file as potential pieces for a later investigative phase when conditions permitted in the context of crime scene number one providing no clear leads and the small collected items still unanalyzable with 1953 technology.

Investigators were forced to return to evaluating foundational elements that could explain why Thomas Brandt and Evelyn Hart disappeared.

With the focus on personal conflicts that might have served his motive, among those closely connected to Thomas, Diana Mercer, his ex-wife, was the only one with a prolonged history of discord and initially inconsistent statements, making it necessary for police to clearly establish the level of tension between them before the incident.

On January 25th, 1953, investigators verified statements from people who knew both parties during the period before and after the divorce in Weedland.

Several of Thomas’s friends described the final months of 1951 and early 1952 as a time of constant tension with Diana frequently appearing at Thomas’s workplace or temporary lodging to question or argue mainly over financial issues, irregular work hours, and suspicions that Thomas was involved with someone else.

One of Thomas’s co-workers clearly recalled an incident a few months before the divorce when Diana drove to the railroad yard and demanded to see him during work hours.

creating a situation that required his supervisor’s intervention.

Another person stated they had heard Diana say she would make him answer for it if Thomas continued pursuing the end of the marriage.

These descriptions were regarded as evidence of long-standing instability in their relationship.

When gathering information from people who knew Evelyn and Castleton, police received comments suggesting Diana may have known about Thomas and Evelyn’s relationship before the divorce was finalized.

One teacher at the school where Evelyn worked said she had seen Diana appear at the teacher’s boarding house around the time Evelyn first moved in.

Although there was no direct interaction, her presence was considered unusual since Diana had no work or personal reason to be there.

Another friend shared that Evelyn had once expressed concern about Diana trying to control Thomas even after they had begun dividing property and preparing to complete the divorce.

These accounts help police understand that the level of conflict may have gone beyond ordinary civil disputes.

In addition to statements, police collected letters and notes still kept by Thomas’s family.

Among them were several handwritten notes from Diana to Thomas in the six months before the divorce.

Some mentioning that he had to take responsibility for the family situation and could not simply cut everything off like that.

The language was not overtly threatening, but expressed strong dissatisfaction and a need for control.

Another undated letter, which the family placed in late 1952, referred to Diana’s inability to bear him disappearing from her life as if no one was affected.

Overall, the content was insufficient to constitute incriminating evidence, but it showed Diana had a high level of emotional attachment and difficulty accepting the end of the marriage.

When cross-referencing this data with statements about her whereabouts on the night of January 17th, police noted clear inconsistencies.

Diana said she stayed home all evening, but two neighbors confirmed they did not see her from after 8:00 pm until around midnight.

No one could confirm where she was during the window that over overlapped with the witness hearing, arguing voices and an engine revving on the trail.

This comparison led investigators to assess that Diana’s statement lacks sufficient reliability based on potential motive, the tense divorce circumstances, her discomfort with Thomas’s relationship with Evelyn, the emotional reactivity described by many acquaintances, and her inability to prove her location during the critical time frame.

Police continued analyzing whether Diana could have traveled from Fargo to the Castleton Wheatland area on the night of the incident.

Estimates showed the distance could be covered in about an hour by personal vehicle and her leaving home unnoticed was entirely plausible.

All these factors reinforced the hypothesis that if someone coerced the victims off their route, Diana had both motive and opportunity to do so.

Although there was still no direct evidence connecting her to the Plymouth or the location of the faint tire tracks.

Based on the overall analysis of personal conflict and prior behavior, Diana remained at the top of the suspect list.

In the end of day report on January 25th, police clearly stated that background investigation showed Diana not only had strong motive but also the capability to be in the area at the time of the disappearance and her inconsistent statements prevented investigators from ruling out her involvement in the case.

While Diana Mercer remained at the top of the suspect list based on the background of personal conflict and inconsistencies in her statements, investigators still had to carry out an important screening step to rule out the possibility that the disappearance involved strangers to the victims, such as longhaul truck drivers, overnight travelers, or individuals passing through the Cassultton Wheatland area at the time of the incident.

This was a mandatory procedure in disappearances showing signs of coercion to ensure no potential suspects outside the victim’s personal circle were overlooked.

On January 26th, 1953, Castleton police reviewed the list of vehicles that passed through the gas station on the western edge of Castleton.

The last stop on the route Thomas usually took.

The station owner stated that on the evening of January 17, only three vehicles refueled.

a produce truck from Tower City heading to Fargo, a two-door Ford driven by a young man, and a delivery truck belonging to a nearby shipping company.

Police quickly verified each case.

The produce truck driver, a local farmer, said he left Tower City around 9,000 pm, refueled in Castleton, continued to Fargo, and stayed overnight at his sister’s house.

His travel time did not overlap with the incident window, and he confirmed he did not head toward We Wheatland.

The driver of the two-door Ford was identified as a college student, driving from Fargo to visit family in Enderland.

He stated he refueled around 9:45 pm, left Castleton shortly afterward, and drove straight along Highway 10 without turning onto any side roads.

Follow-up checks found no indication he was in the Maple River area on the night of January 17.

The third vehicle was a delivery truck for a garment transport company.

The driver confirmed he completed his final delivery in Fargo and returned to Castleton before 10,000 poor his then left the company around midnight to head home east of town.

His route did not pass through the Wheatland area and did not cross the location where the faint tire tracks were recorded.

At the late night diner near Castleton, police interviewed additional customers present on the night of January 17.

The list included four long haul drivers and two local travelers.

All four drivers provided consistent schedules.

One was driving a refrigerated truck to Bismar.
