The state police are hoping this video will help them track down witnesses to an apparent road rage killing on I-81.
Timothy Davison, 28, was driving home to Maine when he was killed about 10 miles north of Hagerstown, Maryland.
He had called 911 as he crossed into Pennsylvania to report that another driver was shooting at him.
Officials say the video shows the suspect's vehicle and other vehicles after the victim was run off the road and just before the fatal shots were fired.
