The driver whose pickup truck collided with two cars Thursday night in Monroeville, killing a woman and her son, might have had a medical problem before the crash, Allegheny County police said Friday.
The 65-year-old pickup truck driver, whose name has not been released, was driving south on Route 286 in Monroeville about 6:30 p.m. when he crossed into the northbound lane, struck two cars and nearly hit a third, Lt. Andrew Schurman of the homicide unit said.
The driver of the first car that was hit was not injured. In the second car that was hit, four people were injured and two of them died.
Jennifer Sample, 28, who was riding in the front passenger seat, died at the scene, and her 7-year-old son, Daniel Eck, died at a hospital.
The driver of that car, whose name has not been released, was in serious condition Friday. A 15-month-old child in the car was not seriously injured.
"At this point, the investigators do not believe drugs or alcohol played a role in the collision but must wait for toxicology testing to be completed to be definitive," Lt. Schurman said.
He said Allegheny County police will turn over their findings to the district attorney's office, which will determine whether charges will be filed.
