A road rage shooting reported last weekend, which killed one, has been confirmed to be "unrelated" to other similar shootings in Kentucky and York County, according to authorities and police investigators who cleared the matter up at a news conference earlier today.

Pennsylvania State Police representative, Steven Junkin, reported that laboratory analysis of samples taken from the scene of the I-81 road rage shooting ruled out any connection to a similar incident in York County.  The investigator did not describe what the evidence used or what authorities understood from repeated calls made to emergency hotlines by victim Timothy Davidson before he was fatally shot.

During the conference, authorities also confirmed that police did not find substancial evidence linking this recent incident to a similar road rage shooting in Kentucky in which a policeman was killed in May 2013.

Junkin added that the latest road rage shooting was random, explaining, "There is absolutely nothing to indicate that Mr. Davison did anything in any way to provoke this. We believe that he was randomly selected."

The suspect of the road rage shooting reportedly drove a dark-colored Ford Ranger XLT during the shooting incident. The car was said to be a 2005 model that had a damaged driver's door.

Police Chief Junkin further confirmed that officials are scouring the Tri-state area for the said vehicle, saying, "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 and we don't want to take that chance."

The police head further explained that law enforcement agencies are liaising closely in the three states where road rage shootings occurred. "We are working tirelessly to make sure that we get this person and get him off the road, quickly," added Junkin.

Chief Junkin said in the conference that he was confident that someone within the Tri-state area would soon come forward to provide information to the police that would help in the road rage shooter's arrest: "We strongly believe that someone in the Tri-state area will be able to provide information that will link the suspect vehicle to the person responsible for this horrible and senseless crime," the police chief added.
