Harry Potter actor David Legeno died last week in the desert near Death Valley, California. His body was discovered by hikers Sunday in a remote location west of Zabriskie Point, and was later removed by a helicopter. According to the Inyo County Sheriff’s Office, the 50-year-old British actor had been hiking at the time of his death.

“The remains have been identified as David Legeno, a 50-year-old United Kingdom man,” the sheriff’s office released in a statement. “It appears that Legeno died of heat related issues, but the Inyo County Coroner will determine the final cause of death. There are no signs of foul play.”

It’s uncertain exactly when Legeno died. His body was partially decomposed and may have been out in the elements–including triple digit temperatures–for several days. Rick Bassman, who served as manager for the actor, confirmed his untimely passing.

David Legeno played the role of a werewolf named Fenrir Greyback in three of the Harry Potter films. He also starred in the 2012 film Snow White and the Huntsman with Kristen Stewart, as well as in Batman Begins in 2005. He recently wrapped production in an upcoming film called The Last Knights which also stars Morgan Freeman and Clive Owen.

Tom Felton played Draco Malfoy in the Harry Potter series of films. He took to both Twitter and Instagram to honor his former costar.

Felton captioned the following Instagram photo taken with David Legeno in Harry Potter costumes, “Dave Legeno. It was always a pleasure. He was a great talent with a heart of gold and always had time for anyone. Dave was a soft, kind gentleman off screen but had the skill to be the complete opposite on screen. He taught me lots, You will be missed mate xx #DaveLegeno.”

David Legeno was also an MMA fighter and boxer. He reportedly lived in southern England along with a daughter.

Word has no doubt spread quickly throughout the Harry Potter family of actors about David Legeno’s death. It will be interesting to see if any of his other costars pay homage to the late actor.
