Mahlon Reyes, a deckhand on Discovery Channel’s “Deadliest Catch,” has died at the age of 38.

Reyes, who began appearing on the reality series in 2012, suffered a heart attack last Saturday in his native Whitefish, Montana, wife Heather Sullivan told TMZ, who first reported the news. Reyes survived and was hospitalized, but never regained consciousness.

Sullivan said Reyes was taken off life support on Sunday. He died “shortly after midnight” on Monday, according to a post on Reyes’ memorial Facebook page.

Reyes has been cremated and some of his ashes will be spread in the Bering Sea by co-stars, Sullivan shared.

A cause of death has not yet been determined by the Flathead County Sheriff’s Office, per TMZ. The family also noted that Reyes did not have any known pre-existing health conditions.

A Go Fund Me page has been organized for Sullivan and the four daughters she shared with Reyes. As of Sunday, over $13,000 has been raised.

A rep for Discovery Channel did not immediately return Page Six’s request for comment.
