Mitchell Guist, who rose to national attention as one-half of the grizzled, alligator-hunting Guist Brothers on History's popular reality show, Swamp People, has died, Louisiana police have confirmed.
According to a statement made by Sheriff Mike Waguespack to WBRZ-TV Baton Rouge, the incident occurred about 9 a.m. Monday. Guist was cruising along the Belle River when he reportedly "fell" out of his boat after having suffered what appeared to be a seizure.
Attempts at reviving Guist through CPR were unsuccessful.
A request for comment made by The Hollywood Reporter to Swamp People production company Original Media went unanswered.
The fun-loving Guist brothers were among Swamp People's most popular subjects and were happy to relate their adventures of alligator hunting, fishing for gar, tracking rabbits or just getting buzzed on beers and sunshine.
