Mitchell Guist died Monday in Louisiana.

Assumption Parish Sheriff Mike Waguespack told CNN, Guist, a cast member for the History Channel show "Swamp People", was boarding a boat near Belle River Landing when he appeared to have a seizure and fell from the boat.

According to ABC, 911 calls indicated that those on the scene went to extreme lengths to try to revive Guist with CPR. In the call, the 911 operator asked, “You say he’s in cardiac arrest?” The caller responded, “Yes sir, we’re blowing and pumping the guy’s chest right now … It looks like he may have had a heart attack."

The History channel which produces "Swamp People" said in a statement, “We are extremely saddened to report that our friend and beloved member of the 'Swamp People' family, Mitchell Guist, has passed away. Mitchell passed on the swamp, doing what he loved. We appreciate your respect for the Guist family’s privacy and hope you join us in sending our thoughts and prayers to his brother, Glenn, and the rest of the Guist family."

Swamp People chronicles the lives of alligator hunters living in Atchafalaya River Basin swamp in Louisiana. Guist appeared on the show with his brother, Glenn Guist. The two shared a boat and worked together during the alligator hunting season.

Their joint biography on History Channel's page reads, "Swampers through and through, Glenn and Mitchell Guist were born and raised on the bayou and lived entirely off the land. These brothers were always up to something, whether it was hunting for their dinner or making use of everything nature has to offer."

The Guist brothers share their love of hunting together in this promotional video for the show.
