Picture: Theresa Allocca Source: Supplied AN American driver accused of running a man off a Pennsylvania highway, then shooting him dead in his car, is likely to kill again if authorities don't arrest him, police warn. Pennsylvania police are conducting a manhunt for the person who killed Maine resident Timothy Davison, 28, during a vicious road rage attack around 2am Saturday morning. Police say the perpetrator is an extremely dangerous individual and "the potential for additional incidents of similar nature is anticipated due to the violent nature of this incident," the Pennsylvania State Police said in a statement on Tuesday. "The acts committed against Mr. Davison were random only to the point of his initial encounter with his assailant," the statement continued. 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. Mr Davison was making the 2,253km trip home after spending the holidays with his family in Florida, when another driver began tailgating him. He called 911 but lost contact as he crossed the Pennsylvania border, then called back to say he was being shot at. Police believe the unknown suspect rammed his truck into Davison's SUV and forced him to get stuck on median strip. The suspect then shot "a couple rounds into the car, striking and killing [Davison]," Pennsylvania State Trooper Robert Hicks told FoxNews.com. Mr Davison was later found dead inside his car. "We're all heartbroken," his mother, Theresa Allocca, told FoxNews.com. The family is currently preparing for his funeral. Mrs Allocca says she hopes the killer is brought to justice. I just hope this doesn't happen to anyone else. This wasn't just road rage. This person is obviously crazy," Mrs Allocca told the Kennebec Journal. Mr Hicks called the shooting "disturbing." "It's definitely something that is rare," he told FoxNews.com. I can't say I've seen something like this before. Local police are encouraging anyone with information about the incident or the killer's identity to come forward. "It is our belief that someone in the tri-state area knows who is or may be responsible for this homicide," a Pennsylvania State Police statement said.
