Tragedy has again hit Discovery’s "Deadliest Catch" as Justin Tennison, a 34-year old crew member on a fishing vessel featured on the show, was found dead Tuesday in an Alaska hotel room, reports the Los Angeles Times’ ShowTracker blog.

An autopsy hadn’t yet determined the cause of death, but TMZ reports that police discovered drugs and alcohol in his room.  Tennison had worked as an engineer on the Time Bandit, a fishing boat led by by Andy Hillstrand and his brother Johnathan, the Times story notes.

It’s the second death to hit the show, as last year Capt. Phil Harris died after a stroke, it adds.
