A western Pennsylvania man has died after lying on train tracks and being struck by a locomotive, but investigators still don't know why that happened.
The Westmoreland County coroner's office has identified the dead man as 21-year-old Tyler Quakenbush, who lived in Latrobe, not far from where he was hit by the Norfolk Southern freight train about 12:40 a.m. Tuesday. Latrobe is about 40 miles east of Pittsburgh.
Investigators have yet to determine whether the death was accidental or suicide, in part, because toxicology tests on the victim's body will take weeks to complete.
Latrobe and railroad police were also investigating.
