WASHINGTON, PA (WCMH) – A mother and son from Columbus were among the victims identified in a deadly crash that occurred Sunday afternoon in Western Pennsylvania.

According to the Washington County Coroner’s Office in Pennsylvania, three people were traveling in a vehicle heading westbound on Interstate 70 near the Claysville Exit, west of Washington, Pa. For reasons that are still unknown, the vehicle veered across the median and into the eastbound lanes.

The vehicle collided with a tractor-trailer on I-70 East at approximately 1:08 p.m. Emergency medics arrived at the scene and pronounced 25-year-old Aisha Trawally dead at the scene.

Trawally, of Columbus, was in the front passenger seat. Her son, 4-year-old Abdul-Salami Touray, was life-flighted to UPMC Washington Hospital, but was pronounced dead at 2:04 p.m. The coroner’s report noted that Trawally was not wearing a seat belt and Touray was not in a child’s seat.

The driver of the vehicle, also not reportedly wearing a seat belt, was taken to a Pittsburgh-area hospital in an unknown condition.

The crash remains under investigation by Pennsylvania State Police.
