MTV star and extreme sports athlete Erik Roner was pronounced dead Monday morning, after a parachute stunt went horribly wrong.

The 39-year-old daredevil, who starred on MTV's "Nitro Circus," was performing a group skydive at a celebrity golf tournament in Olympic Valley, California when he fell victim to a bad landing in front of over 100 spectators.

"Roner was the third member of a three-man parachute team to jump and, according to witnesses, was off the drop zone target on descent and hit a large tree," read a statement from Nitro Circus. "He was then transported to a local hospital where he was pronounced dead."

Many people watched in horror as Roner hit the tree at high speed. Emergency personnel quickly responded, but Roner reportedly died immediately from the impact.

"He hit a tree ... he hit a tree so hard. I don't know what happened from there," eyewitness Roy Tuscany told Teton Gravity Research.

Roner was involved in a variety of extreme sports throughout his life, including BASE jumping, skydiving and professional skiing. One the daredevil's most notable stunts involved attaching dozens of large balloons to a lawn chair, whisking him 8,000 feet into the sky. Roner then popped the balloons with a shotgun before parachuting back to the ground below.

"People sit there and say 'Look, this guy's a loose cannon,'" Roner said in 2005, according to The Washington Post. "'He's a kook.' It's not the case at all. ... Everything's very calculated. I don't do it unless I know I can pull it off."

MTV released a statement expressing its condolescenes, saying, "We at MTV and MTV2 are saddened to hear about Erik's passing, and will miss the boundless energy, fearlessness and good vibes he brought to our audience. Our hearts go out to his friends and family."

Roner is survived by his wife and two children.
