Pennsylvania State Police are investigating a two-vehicle Pennsylvania car accident that killed two 18 year-olds and injured a third person on Monday in Jefferson Township, near Waynesburg, Greene County.

The collision occurred shortly after 11:00 a.m. on Eaton Run Road near the intersection of Route 21, according to troopers at the Waynesburg barracks. According to officials with the Pennsylvania State Police, Bethanie Orwig and Holly Lowry, both of Nemacolin, died at the crash scene. Another victim, identified as Shelvia Lough, was transported to Ruby Memorial Hospital in Morgantown, West Virginia.

Lough’s boyfriend, Chris West, said the 29 year-old will require surgery. “They said she was stable, but I didn’t know the extent of the injuries because all I know is her car was demolished,” West said.

A woman was killed Saturday night in a multi-vehicle Pennsylvania car accident at 61st Street and Passyunk Avenue in Southwest Philadelphia.

The woman, whose name police have not released, was traveling south on 61st Street shortly after 11:20 p.m. Saturday in a black Buick. According to officer Tanya Little of the Philadelphia Police Department, the woman was stopped at a traffic light when a green Saturn driven by a 31 year-old man crashed into her car, forcing it into the intersection, where it was struck by a westbound Kia Optima.

The woman driving the Buick, believed to be in her 30’s, was pronounced dead at the Hospital of the University of Pennsylvania.

The accident remains under investigation.
