At least four people are dead and three Pennsylvania state troopers injured after a person allegedly began "shooting at random" along a rural road, KDKA-TV reported on Friday.

The station reported that one of the people killed was the alleged shooter. Two other men and one woman were killed during the incident in Frankstown Township in the central part of the state.

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."
