Dave Legeno, the actor perhaps best known for his portrayal of werewolf Fenrir Greyback in the Harry Potter series, was found dead following a desert hiking outing in Death Valley, California, according to a statement on Friday from the Inyo County Sheriff’s Department. He was 50 years old.

The sheriff's department added that it appears Legeno died of heart-related issues, according to TMZ. He was found near Death Valley’s famed Zabriskie Point.

The actor played roles in films like Batman Begins, Snow White and the Hunstman and Snatch, and had a part in the upcoming crowdfunded film Enemy of Man with Potter costar Rupert Grint. Legeno was also an expert mixed martial artist.
