Autopsy results on Mitchell Guist, a star of the reality TV show "Swamp People," should be ready Wednesday, a local sheriff in Louisiana said.
A cause of death has not yet been determined.
Guist, 47, was working to build a houseboat when he appeared to have a seizure and fell backwards in his boat, said Assumption Parish Sheriff Mike Waguespack.
He was with another person on the Intercoastal Waterway, about 75 miles from New Orleans, at the time of his collapse.
That person, who did not want to be identified, got Guist back to a boat landing, performed CPR and called his wife, who in turn called 911, said the sheriff.
Guist was transferred to the Teche Regional Medical Center in Morgan City, where he was pronounced dead Monday.FULL STORY
