MIAMI (CBSMiami) – A good samaritan turned in a severed arm to the Coast Guard patrolling around President Donald Trump’s Mar-a-Lago estate on Palm Beach.

Officials say the arm belongs to a snorkeler who was struck, run over by a boat on the north end of the island Thursday afternoon.

The arm was rushed to land, where it and the injured man were rushed to the hospital with life-threatening injuries.
