Mitchell Guist, one of the stars of Swamp People on the History Channel, died this morning from injuries suffered during a fall off his boat.
Authorities tell WBRW.com the accident occurred around 9 a.m. along the Belle River in Louisiana.
Attempts to perform CPR on Mitchell - who appeared on Swamp People along with his brother, Glenn, and hunted alligators on the program - were unsuccessful and he was pronounced dead at a local hospital not long after the boat returned to shore.
No reason for the accident or cause of death has been reported, though onlookers say Guist appeared to suffer a seizure.
"We are extremely saddened to report that our friend and beloved member of the Swamp People family, Mitchell Guist, has passed away earlier today. Mitchell passed on the swamp, doing what he loved," a rep for the History Channel said in a statement.
