Officials say a 73-year-old man died in the Florida Keys after falling overboard while trying to remove a fishing line that became tangled in his boat's propeller.
Accroding to the Florida Fish and Wildlife Conservation Commission, Francisco Anaya was found dead by another boater about nine miles north of Duck Key on Saturday.
Investigators say Anaya had gone out fishing with 85-year-old John Dernay.
They believe Dernay tried to rescue Anaya by throwing him a buoy and reaching him with a fishing pole. When that failed, Dernay entered the water but was unable to get himself or Anaya back in the boat.
The commission says Anaya's apparent drowning is the fourth diving or boating death in the Keys in the past 10 days.
