The driver of a Jeep involved in a head-on crash Aug. 16 a quarter-mile from the intersection of Oneida Valley and Mahood roads in Oakland Township has died.

Sara J. Brown, 20, of Butler, died Saturday, Aug. 26 in Allegheny General Hospital, according to her obituary.

Police said the Jeep was traveling southbound on Oneida Valley Road at around 2 a.m. Aug. 16, when the vehicle crossed the center line. It then traveled over the white fog line, hit an embankment and overturned in the northbound lane. A tractor-trailer traveling in the northbound lane hit the Jeep, police said.

The tractor-trailer then traveled into the southbound lane and hit a guardrail, police said. The driver was uninjured.

Gary Wulff, chief of Oneida Valley Volunteer Fire Department, said three of the four people occupying the Jeep were ejected from the vehicle and were lying on the road. It took first responders 15 minutes to extricate the fourth person from the vehicle. All of them were unconscious, he said.

According to a crash report from state police, the Jeep was driven by Brown, and was carrying three passengers: Clayton J. Snow, 20, of Butler, Benjamin H. Claypoole, 18, of Emlenton, and a 13-year-old boy from North Washington.

The crash happened just hours after another head-on collision on the same road that took the lives of two people, Hayden Ernest, 19, of Hilliards, and Jacqueline Rock, 32, of Chicora.
