State police are searching for a lapis blue 1993-97 Ford Ranger pickup truck like this. A man driving a similar pickup forced Timothy Davison's car off Interstate 81 in Franklin County on Jan. 4, then fatally shot Davison.

State police said they now believe the killer's pickup truck was a lapis (dark) blue 1993-97 Ford Ranger that may appear black in certain lighting, and would have sustained damage to the driver's side. Police said they determined the truck's color by analyzing paint transfer on the victim's car.

The killer could have had the damage repaired by now, according to police, who are encouraging repair shops and insurance agents to report "past, present and future claims of vehicle damage to any such vehicles."

Pennsylvania Crime Stoppers continues to offer a $10,000 reward for information leading to the killer's arrest and prosecution.

Davison's family is now offering an additional $10,000 reward, and will be creating a website about the homicide, police said.

Police said they strongly believe someone in the tri-state area has information that would help the investigation, even though it might seem insignificant to the person.

Anyone with information about Davison's homicide is asked to call Pennsylvania Crime Stoppers at (800) 4PA-TIPS. Tipsters can remain anonymous.
