Florida ? An elderly sheriff’s deputy was fatally shot as he transported a convicted robber to court Wednesday, and authorities captured the convict after a manhunt and said he was found with the deputy’s gun.

Broward County Sheriff Al Lamberti said Michael Mazza – already serving a life sentence for armed robbery – may have had accomplices who ambushed 76-year-old Paul Rein as he drove Mazza to court for his trial on a separate robbery.

Mazza, 40, was arrested at a Hollywood pawn shop shortly after noon, about four hours after Rein was found shot and bleeding in a parking lot, Lamberti said.

The two were alone but separated by a partition in a medical van, and Mazza was wearing handcuffs, authorities said.

Mazza was being transported in the medical van because he had complained of a bad back. Lamberti said it was a routine transport, done “hundreds of times a day.”
