2ND UPDATE, 10:47 PM: The New Orleans coroner’s office said today that Shawn Robinson died of natural causes. The autopsy report found that 41-year-old son of legendary stuntman Dar Robinson suffered from hypertensive heart disease, which can lead to heart attacks and that he died of heart failure. The toxicological report found no drugs or alcohol in his system, other than a small amount of Xanax, which the coroner ruled did not contribute to his death.

UPDATED, 3:37 PM, August 4: Lionsgate today issued a statement about the death of stuntman Shawn Robinson, who had been working on its movie Deepwater Horizon before he was found dead in a hotel room last week: “On behalf of the producers, cast and crew of Deepwater Horizon and the entire Lionsgate family, we want to send our most heartfelt condolences to the family of Shawn Robinson. Shawn was a gifted stunt performer and a beloved and trusted member of our crew. We grieve with his family over this tremendous loss.”

PREVIOUSLY, August 4: Shawn Robinson, a veteran Hollywood stuntman and rigger whose credits include Guardians Of The Galaxy and the first three Transformers films, was found dead last week. He had been working on Peter Berg’s new film Deepwater Horizon in New Orleans; when he didn’t show up for work on July 28, a fellow stuntman went to his hotel room and found Robinson’s body. The Orleans Parish Coroner’s Office hasn’t released a cause of death pending toxicology results.

Robinson, the son of legendary Hollywood stuntman Dar Robinson, specialized in rigging equipment so that stunts could be performed safely. His prolific career, which spanned nearly 25 years, included stunts on such films as Captain America: The Winter Soldier, The Lone RangerFast & Furious, X-Men: The Last Stand and Steven Spielberg’s War Of The Worlds and The Lost World: Jurassic Park. He was also a stunt rigger on numerous films, including Captain America: The Winter Soldier, Catwoman and Hollywood Homicide.

“The whole stunt community is in shock,” said T.J. White, a stunt coordinator who’d worked with Robinson on several projects. “He touched the lives of hundreds of stunt performers across the country. He was an amazing stunt rigger and worked on some of the biggest shows in town and was responsible for the safety of hundreds of stuntmen and women. He was a very likeable guy who always had a smile on his face. This is tragic.”

Robinson came from a family of stuntmen. His brother Troy is Vin Diesel’s stunt double, and their father Dar often is said to have been one of Hollywood’s greatest stuntmen. Dar Robinson, who once doubled for Steve McQueen, was killed in 1986 while filming a routine motorcycle chase scene in the Arizona desert when his bike went off a cliff. Director Richard Donner dedicated the 1987 film Lethal Weapon to him.
