( CNN ) -- In multiple 911 calls shortly before he was killed , a man said he was being chased by an enraged motorist -- right up to when he was apparently run off the road in Pennsylvania and then shot to death , police said Friday . Timothy Davison , 28 , was driving home to Maine along Interstate 81 early last Saturday when he was shot multiple times and killed in Antrim Township . So far , there is no indication that Davison initiated the incident or provoked the shooter , Pennsylvania State Police Capt . Steven Junkin told reporters Friday . Davison may have first encountered the shooter on Interstate 70 in Maryland and traveled between 13 and 15 miles , with the gunman in pursuit , before being forced off the road just beyond the Pennsylvania state line , authorities said . Junkin said Davison called 911 from Maryland and Pennsylvania , but he declined to provide details . Authorities have not released the contents of those 911 calls , citing the ongoing investigation . A task force made up of Maryland , Pennsylvania and West Virginia state police , as well as FBI agents , is seeking help from the public and operators of body shops in finding a `` dark colored '' Ford Ranger XLT pickup with damage on the driver 's side from ramming into Davison 's car . `` How concerned are we that it 'll happen again ? '' Junkin asked . `` 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 do n't know . We do n't want to take that chance . '' The Maine resident ended up shot multiple times , a death that authorities have ruled a homicide . Anyone with information is asked to call Crime Stoppers at 800-472-8477 . Investigators initially believed the same motorist may have been behind another road rage shooting eight hours earlier and 56 miles northeast , but Junkin said Friday that the two crimes do not appear to be related . James Allocca , Davison 's uncle , told CNN this week that the family `` wants justice before someone else gets hurt . '' The victim 's father , Timothy Davison Sr. , said he learned about his son 's death when police arrived at his door Saturday . `` I ca n't begin to tell you what it 's like to hear that , '' he said . `` It 's not right . '' He went to Pennsylvania on Tuesday to collect his son 's personal belongings . His son , he said , was a `` great guy and a very easy kid to raise . '' `` He cared for everyone around him , '' he said . `` He was a rugged kid , extremely sensitive . '' Davison worked at his father 's construction business . He said he hoped to meet his son 's killer . Asked what he would say , Davison said : `` That is for me . '' `` There are different levels of loss , '' Allocca said . `` This has to be the worst .
