Tragedy has struck the cast of "Swamp People".

Louisiana police confirmed that Mitchell Guist, one-half of the gator-hunting Guist Brothers, died Monday morning after apparently suffering a seizure in his boat while cruising the Belle River.

A spokesperson for The History Channel, which carries the show, issued a statement saying, "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."
