(New Paris, OH)--A death investigation that began Wednesday night at a state-line truck stop was continuing Thursday morning.  Deputies responded to the Petro Travel Center on U.S. 40 at around 8:20 Wednesday night.  The Wayne County Sheriff’s Office initially believed it was a fatal crash on the ramp onto westbound I-70.  But, Preble County Sheriff Mike Simpson said they learned that was not what happened.  "The semi driver made some statements that he's responsible for the death of the female in the truck and it wasn't because of the crash," Simpson said.  He then ran across U.S. 40 but was quickly caught.  He was taken to the hospital to be checked out.  A Petro employee indicated that the killing occurred in the truck stop’s parking lot and that the man came in to take a shower after it occurred.  The identities of both the victim and the suspect have not been released.
