Hot Springs County, WY — April 6, 2025, Sandra Swallow was killed and two people were injured in a car accident at around 8:43 P.M. on Wyoming 120.
An investigation is underway following a car accident that left one person dead and injured two others during the evening hours of April 6th. According to official reports, Sandra Swallow was traveling in a Subaru Impreza on Wyoming 120 in the northbound lanes near milepost 38, when for unknown reasons the vehicle drifted into the opposite lane and collided head-on with a Chevy Silverado which was pulling a car on a trailer, the impact of which caused the pickup to roll over.
When first responders arrived on the scene, they found that Swallow was without signs of life and was pronounced deceased, while the driver and passenger of the Silverado sustained serious injuries and they were transported to the hospital for treatment. At this time there has been no further information released from the accident, including the identity and status of pickup’s occupants, however this remains an ongoing investigation and more details may be released by authorities in the future.

When a vehicle crosses into oncoming traffic and causes a head-on collision—especially one that results in a fatality and serious injuries to others—it’s essential that the investigation focus on more than just who was in which lane. To uncover the full scope of what happened, investigators should begin with three critical questions: (1) Did the authorities conduct a thorough and complete investigation? (2) Has anyone examined whether a mechanical issue or vehicle defect contributed to the crash? (3) Has all the electronic data from both vehicles been collected and preserved?
The initial question—why the Subaru drifted into oncoming traffic—requires close analysis of the road conditions near the crash site. Investigators should examine whether the stretch of Wyoming 120 near milepost 38 had any contributing factors, such as reduced visibility, shoulder erosion, high winds, or poor lane markings. In rural areas especially, even subtle environmental or design issues can lead to lane departures, particularly at highway speeds.
Mechanical failure must also be considered. A malfunction in the Subaru’s steering or braking systems, a tire blowout, or even a problem with the vehicle’s electronic stability controls could explain the sudden lane drift. Investigators should conduct a complete inspection of the vehicle and evaluate whether any known issues, maintenance lapses, or recalls may have played a role.
Electronic control modules (ECMs) in both the Subaru and the Silverado can hold critical pre-crash data. This includes vehicle speed, throttle position, braking effort, and steering activity. In a crash where one vehicle was towing a trailer and rolled over after impact, that data becomes even more valuable in reconstructing the timeline and understanding the dynamics of both vehicles. Securing this information promptly is essential, as it may be overwritten or lost during post-crash handling.
Until each of these areas—road conditions, vehicle performance, and digital crash data—are fully reviewed, the cause of the crash cannot be considered fully understood. A comprehensive investigation is necessary not only to determine what caused this collision, but also to identify any contributing factors that might help prevent similar incidents in the future.
