Police investigating the shooting death of a Maine man along an interstate highway in Pennsylvania said Tuesday they are scrutinizing a similar shooting that happened eight hours earlier and about 30 miles away.
State police said there are similarities between the shooting that took the life of 28-year-old Timothy Davison a few miles north of the Maryland state line early Saturday and Friday night's shooting in which a bullet struck the driver's head rest.
"Both investigations will be treated as being related until conclusive evidence proves otherwise," the Pennsylvania State Police said in a statement that sought information from the public.
A task force of state troopers from Pennsylvania and Maryland and FBI agents was formed to track down who killed Davison along Interstate 81.
Davison was driving back to his home in Poland, Maine, after a holiday visit with relatives in Florida. He called 911 to report some sort of problem and that he was being chased and shot at by someone inside a dark-colored pickup truck, authorities have said.
Police say the pickup apparently rammed his vehicle onto a grassy median before the driver or possibly a passenger shot him around 2 a.m. Police have said the pickup truck may be a Ford Ranger with damage to the front quarter panel or driver's side door.
"The acts committed against Mr. Davison were random only to the point of his initial encounter with his assailant," the statement said. "Beyond that, the acts against him were very deliberate, calculated, and violent. With that said, the potential for additional incidents of similar nature is anticipated due to the violent nature of this incident."

Police have said there is no indication that Davison knew his killer. Davison's family in Maine described him as a gentle person and a talented mechanic who loved the outdoors.
The Friday evening shooting occurred on a local road in Monaghan Township in Pennsylvania's York County. A driver told police that someone in a black pickup truck followed him recklessly, then fired several shots into his truck.
