Sad news for 'Swamp People' fans and the family of Mitchell Guist. According to TMZ, Mitchell was out in his boat along the Belle River when he fell. Witnesses say he appeared to have been suffering from a seizure. TMZ reports that another person on the boat returned the vessel to the dock and called 911. Emergency personnel responded to the scene and transported Mitchell to a nearby hospital, but it was too late.

UPDATE: A rep for The History Channel has released a statement on the passing of Mitchell Guist, one of the stars on their popular 'Swamp People' television program.

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.

Chris Reed had an interview with the brothers when they came through last year for our Outdoor Expo. The guys were as genuine as can be and truly two of the most happy spirits you could ever meet. Check out the video and you'll see for yourself!

RIP Mitchell, from the Hot Crew!
