Motive sought in Pa. slayings of 3; gunman killed

Both troopers turned around and pursued the suspect, and a third patrol car arrived and tried to block the path of the pickup, which rammed the car head-on, injuring the trooper driving, police said. One of the other patrol cars then rammed the back of the suspect's truck, and a gunfight with the first two troopers ensued. One was hit in the chest and wrist.

"His body armor saved his life," Bernard said.

The suspect was struck by police gunfire and was pronounced dead at the scene. The three troopers were treated at a hospital but are expected to be all right, authorities said.

The district attorney's office classified Michael's death as a justifiable homicide and said it would not pursue criminal charges against the troopers.

Police have not released information about the weapon or weapons used by Michael. Bernard said police had had some contact with Michael but declined to go into detail.

"We've had other incidents, but nothing to this extent," the sergeant said. Online court records show no criminal record for him in Pennsylvania or in the state's federal courts.
