Pennsylvaania State Police in Girard are still investigating the traffic death of a former 21-year-old Greenville resident.

Jason Gruver of Edinboro, formerly of 8 Argus St., Greenville, was killed Monday after the car in which he was riding was hit by a school bus in Erie County, state police said.

State police said Tuesday they have nothing more to report about the crash.

A coroner's report was incomplete Tuesday, though Erie County Deputy Coroner Korac Timon speculated the cause of death to be head and chest trauma. The coroner's office expects to have a full report today.

Gruver, a 2000 Reynolds High graduate who attended Mercer County Career Center, was not wearing a seatbelt, police said.

Police said the driver, Joy Lynn Rizor of Utica, lost control of her car at 2:40 p.m. on snow-covered U.S. Route 6N in Elk Creek Township. The car crossed the center line and was hit by an eastbound bus, which was transporting a seventh- and eighth-grade volleyball team from Northwestern Middle School in Albion to a match at General McLane schools in Edinboro.

Ms. Rizor, who was wearing a seatbelt, was transported to Hamot Medical Center in Erie. Some volleyball team members were also taken to Hamot, police said.

Hospital officials would not release Ms. Rizor's condition Tuesday.
