WJAC-TV reported that the suspect was “mobile” and shot victims along the road.

Richard Consiglio, the local district attorney for Blair County, told The Altoona Mirror that two of the troopers were wounded in a shootout with the alleged gunman, while the third trooper incurred his injury in a crash during the incident, which he said “extended over several miles.”
