HARRISBURG, Pa. (AP) — State police said Wednesday they have narrowed down the description of a vehicle being sought in the apparent road-rage slaying of a Maine man along an interstate highway in south-central Pennsylvania last month.

Paint evidence has prompted investigators to search for a 1993-97 dark lapis blue Ford Ranger pickup, which may appear black depending on lighting and probably has damage on the driver’s side, state police said.

Repair shops and insurance agents should report any such vehicles with similar damage, Lt. Adam Kosheba of the Harrisburg barracks said.

Timothy Davison, 28, was driving home to Poland, Maine, on Interstate 81 when he was shot to death a few miles north of the Maryland line around 2 a.m. Jan 4, police said.

Davison had called 911 as he crossed into Pennsylvania to report that another driver was shooting at him. Police believe the pickup driver rammed Davison’s car into a grassy median, before the driver or perhaps a passenger shot him about 10 miles north of Hagerstown, Md.

Kosheba said investigators believe the suspect vehicle and its driver were observed by several motorists along I-81 in Maryland, and possibly by other motorists after Davison’s vehicle veered into the median strip.

Davison’s family and the Pennsylvania Crime Stoppers organization are each offering a $10,000 reward for information leading to the arrest and prosecution of the killer, state police said.
