Investigators with the Interstate 81 Homicide Task Force don't believe last weekend's highway slaying in Franklin County is connected to an incident that happened about seven hours earlier, in which one driver fired several gunshots at another in northern York County.
"We believe with a reasonable level of certainty these two incidents are not related," said Pennsylvania State Police Capt. Steve Junkin, Troop H commander.
Junkin said task-force members came to that conclusion after reviewing crime-lab results, as well as statements from witnesses and the man who survived the road-rage attack in Monaghan Township, outside Dillsburg.
Road rage: In that case, a bullet lodged in the headrest of a driver who was traveling in the 100 block of North York Road about 6:45 p.m. Jan. 3, but the driver escaped injury, according to Carroll Township Police Sgt. David Smith.
The driver, whose name has not been released, told police a black Nissan pickup truck was following him and driving recklessly, Smith said. The black truck pulled aside the victim, at which point its driver shot the victim's vehicle numerous times, according to Smith.
A highway shooting in Kentucky also appears to be unrelated to the I-81 homicide, Junkin said at a Friday-morning press conference at the state police barracks in Chambersburg, Franklin County.
Forced off road: Timothy Davison, 28, of Poland, Maine, was shot to death around 2 a.m. Jan. 4, just north of the Mason-Dixon Line, police have said.
Prior to being shot, Davison called 911 several times, telling dispatchers someone in a dark-colored pickup truck was chasing him and shooting at him.
The driver of a Ford Ranger XLT-style pickup truck forced Davison's car off the road, police have said. He then killed Davison, who died of mulitple gunshot wounds, according to Junkin.
Headed south: Investigators suspect that after the fatal shooting, the killer turned around and headed south, police said.
Police don't think Davison did anything to cause his own homicide, according to Junkin.
While it's been reported the killer was driving a dark-colored pickup truck -- perhaps blue -- Junkin noted it was dark at the time. Because of that, police aren't ruling out any color pickup truck except white, he said.
Investigators are concentrating their search for the killer in Pennsylvania, Maryland and West Virginia, but Junkin said that doesn't mean the killer is in any of those states.
He confirmed police have looked at footage from highway cameras set up in several states.
"We obviously have an individual out there who was so incensed ... he took it to that next step," Junkin said, so there's no telling if he will strike again.
Motive unknown: Trooper Adam Reed, a state police spokesman, said task-force members have not yet determined whether Davison's killing was the result of road rage. He said road rage has not been ruled out.
The Interstate 81 Homicide Task Force is comprised of state police in Pennsylvania, Maryland and West Virginia, as well as the FBI, the Franklin County district attorney and the Franklin County coroner.
