Federal Agent Dies After Shooting Outside Pembroke Pines Post Office PEMBROKE PINES, Fla. -- A U.S. Customs and Border Protection agent has died after he was shot outside a Pembroke Pines post office Tuesday morning, police said. The shooting happened at the South Florida Mail Processing Center located at Dykes Road and Pines Boulevard. According to police, the victim and another man got into a fight.
