WAFB-TV has confirmed that a 21-year-old LSU has died after trying to save a child at a beach in Florida last week.

Officials from LSU told WAFB that Layne Gravois, and electrical engineering student at the school, died after he and two others swam to save a boy being pulled under by a rip tide at Miramar Beach, Florida. Nicholls State University also confirmed to the TV station that the other two men were students at their school. Those two were identified by the school as Jordan Servat and Reed Boudreaux, who were both hospitalized after the incident.

The same day, at the same beach, 55-year-old Kim Grady of Dunwoody, Georgia was also killed when he drowned.

South Walton Fire & Rescue officials told WJHG-TV in Florida that there was a total of 11 people who had to be rescued that day, all in Miramar Beach. While the beaches moved to a "double red flag" after the incidents, the beach only has a "single red flag" during the fatal accidents.

The "flag" system for beaches operates under a 5 "flag" system. The purple flag marks "stinging marine life" like jellyfish and stingrays are present. A green flag indicates low hazards in the water, while a yellow flag is for medium hazards. The single red flag represents high hazard, while a double red flag means the beach is closed to the public.

The Florida beach flag warning system was developed after 2002 legislation directed its creation, and became uniformed after 2005 legislation standardized the use across the state.
