A Pennsylvania man died Thursday while diving for lobster off Plantation Key in the Upper Keys.
The 52-year-old man, whose name hasn't been released because his family hasn't been notified, was diving from a private boat with two friends in the area of Davis Reef.
Monroe County Sheriff's Office Deputy Becky Herrin said the man and one of the friends were diving together when the victim signaled he wanted to surface. The two did, but as the friend was removing his gear, he looked back and saw the victim had slipped back under the surface, Herrin said.
The friend went back in and pulled the victim to the boat but he was unresponsive. Cardiopulmonary resuscitation was started and 911 was called as they headed to shore. They got in at the Tavernier Creek Marina, where paramedics took over and took the man to Mariners Hospital, where he was pronounced dead.
An autopsy will be done to determine the cause of death.
