HOLLYWOOD, Florida (CNN) -- A man serving a life sentence for robbing a drugstore has confessed to overpowering and fatally shooting a deputy who was taking him to court Wednesday, authorities said. Michael Mazza, 40, was arrested outside a pawn shop in Hollywood, Florida, hours after the death of Broward County Deputy Paul Rein sparked a massive manhunt. It was the third shooting of a Broward County sheriff's deputy in four months, and the second fatality. The incident happened as Mazza was being taken to the second day of his trial in connection with the armed robbery of a Coral Springs bank, Sheriff Al Lamberti said.

The struggle began when @placeholder apparently pulled the medical transport van over at an intersection.
@placeholder, meanwhile, is believed to have hitchhiked his way down to Hollywood, about 20 miles away.
He was on trial for robbery of the @placeholder bank.
Lamberti said @placeholder's wife spoke to her husband by cell phone just 10 minutes before he was shot.
