Tragedy struck Saturday night on the southbound lanes of the 57 Freeway in San Dimas, California, as a fatal collision claimed the life of a pedestrian. Authorities have now identified the victim as Thomas Percy, a 68-year-old resident. The incident was confirmed by the California Highway Patrol (CHP), who reported that Mr. Percy was walking in the slow lane of the freeway when the accident occurred.

According to investigators, the collision took place when Thomas Percy was on foot within the active lanes of traffic. For reasons still under investigation, Percy was hit by at least one southbound vehicle while he was in the slow lane. Responders quickly arrived on the scene, but unfortunately, the injuries sustained by Mr. Percy proved to be fatal. The exact sequence of events, including whether Percy was struck by multiple vehicles, will be the subject of an ongoing investigation by the CHP.

Freeway accidents involving pedestrians underscore the inherent dangers of walking along or across busy roadways, particularly during nighttime hours when visibility is reduced. The stretch of the 57 Freeway where the collision occurred is known for heavy, fast-moving traffic, making any pedestrian presence on the roadway particularly hazardous. It is not currently clear why Mr. Percy was walking on the freeway at that time, and officials have not released details about what factors may have contributed to the incident.
