Fox and Friends reported this morning on the hunt for a man who is suspected of running another driver off the road, then shooting him to death on the side of a Pennsylvania highway.

Authorities say the victim, 28-year-old Timothy Davison, called 911 while the suspect was shooting at him on I-81 as he crossed from Maryland into Pennsylvania.

Davison, a resident of Maine, was heading home from Orlando after visiting family for the holidays.

Here's more from FoxNews.com:

Police believe the driver of an unidentified pickup truck rammed Davison's SUV, forcing the vehicle to get stuck in a snow-covered median along the highway.  

Trooper Rob Hicks told the Kennebec Journal that the gunman then got out of the truck and fired “multiple shots” into the SUV. Davison died a short time later after being taken to a local hospital.

“I think we can call it a road rage incident,” Hicks said. “At this point we haven’t found anything that would connect the two men.”

No arrests have been made in the shooting and Hicks said no witnesses have come forward as of Sunday night. Authorities have asked the FBI to assist in the investigation.
