The actor was found dead by two hikers in Death Valley. It appears he may have died of heat-related issues, and was likely deceased for a few days before he was found. News story here.

In addition to being an actor, he was also an accomplished mixed martial artist. Dave Legeno's most famous roles include:

1. Harry Potter franchise: Fenrir Greyback
2. Centurion: Vortix
3. Snatch: John
4. Batman Begins: League of Shadows member
5. Snow White & the Huntsman: Broch

RIP. :c

I read about this and it saddened me a lot. Especially, since I was watching all the Harry Potter movies during a marathon when I heard the news. :(

Oh no :( RIP!
