JACKSONVILLE, Fla. (AP) - Investigators say the man accused of fatally shooting two people and wounding two others was shot 28 times by Jacksonville police.

New details were released Saturday about the police-involved shooting that left 33-year-old Christopher Scott Kilgore dead. Police say the shooting most likely lasted only a few seconds.

Law enforcement had been looking for Kilgore since Monday. Clay County authorities said he fatally shot his brother and a friend. Kilgore also shot his parents, but they survived.

Officers were following up on a call about a suspicious person Friday when they confronted Kilgore, ordering him to give up. He refused. The officers then shot him. Kilgore had been armed with a handgun and a shotgun, but never returned fire.

The motive for the shooting remains unclear.
