KEY BISCAYNE, Fla. (AP) - Authorities are investigating a fatal boat accident involving a South Florida radio personality behind the wheel.
The Florida Fish and Wildlife Conservation Commission reports that Lazaro Mendez, known as DJ Laz, was operating the 40-foot boat in Key Biscayne on Sunday. Several people were helping to push the boat off a sandbar when one of the engines caught the body of 23-year-old Ernesto Hernandez. He later died at a nearby hospital.
Investigators are trying to determine how the accident happened and will look into whether alcohol played a role.
Mendez posted a statement on his Facebook page on Monday. He wrote he was "incredibly distraught over the unfortunate accident." He also says he has and "will continue to cooperate fully with investigators during this tragic time."
