A Pennsylvania coroner confirms the driver and the pregnant coach killed in the crash of a bus carrying college women's lacrosse players died of injuries caused by the accident.

The Cumberland County coroner's office said Monday that toxicology tests are pending on 61-year-old driver Anthony Guaetta, of Johnstown. The Saturday morning crash also killed 30-year-old Seton Hill University women's lacrosse coach Kristina Quigley and her unborn child.

Seton Hill player Amanda Michalski remained in fair condition at Penn State Hershey Medical Center.

Twenty-three players and coaches were aboard the bus when it crashed on the way to a game at Millersville University. Trooper Rob Hicks says it will be weeks before state police determine why the bus crashed.
