Trooper Joseph Bullock was shot and killed when he encountered a disabled vehicle on I-95 just north of the interstate rest area in Martin County.
He stopped to assist what he believed to be a disabled motorist at about 10:15 am. One of the occupants of the vehicle fatally shot him as he approached.
A Riviera Beach police officer who happened to be driving past the scene shot and killed the subject.
Trooper Bullock was a U.S. Air Force veteran and had served with the Florida Highway Patrol for 19 years. He is survived by his parents and two sisters.
