Motorist shot dead in Pennsylvania road-rage incident while on phone with 911

Authorities in Pennsylvania are investigating a road rage incident that turned deadly.

According to police, there is no indication that Timothy Davison initiated the encounter that ended his life. They claim that the gunman pursued Davison down Interstate 70 for 13 to 15 miles before forcing him off the road and shooting into the cabin of his SUV.

At a press conference covered by CNN, Pennsylvania State Police Captain Steven Junkin told reporters that his department is "concerned" that "it'll happen again."

"We obviously have an individual out there who was so incensed that he continued to pursue Mr. Davison and took it to that next step. He murdered an individual for whatever slight that he perceived. Will this person do it again? We don't know. We don't want to take that chance."

Junkin also indicated that Davison was communicating with emergency dispatchers while being chased down by the driver of a "dark colored Ford Ranger XLT pickup."

Police have not released the tapes of the conversation to the public, but did share them with Davison's father, Timothy Davison, Sr., who expressed hope that his son's murderer would be found, so he could meet him.

When asked why he would want to do so, he only said, "[t]hat's for me."
