Peggie Lanizzani of Umatilla, Florida and her sister who is from Illinois were both visiting the Keys. They were on a snorkeling trip together on the Sundiver III. Her sister told Sgt. Susan Keene they were both floating in the water together when she realized something was wrong. She said she began pulling her sister back to the boat and yelled for help. She said someone from the boat assisted them on board.
According to employees on the boat, CPR was started on Lanizzani, and continued as the boat headed in to shore. When the boat docked, Lanizzani was turned over to paramedics just after 1 p.m.
Lanizzani was transported to Mariner’s Hospital where she was pronounced dead. An autopsy will be done to determine the cause of her death.
