U2’s longtime tour manager, Dennis Sheehan, was found dead Wednesday (May 27th) in his West Hollywood hotel room just hours after the band performed the first of five Los Angeles-area concerts at the Forum in Inglewood.

According to the Los Angeles Times, the 68-year-old Sheehan was found unconscious and not breathing at the Sunset Marquis Hotel at 5:30 am Wednesday morning when Los Angeles firefighters were called to the scene. Fire Inspector Randall Wright says Sheehan was in cardiac arrest when they arrived at around 5:40 am but did not transport anyone to the hospital.

Craig Harvey, spokesperson for the LA County Coroner’s Office, said it’s possible Sheehan died of natural causes, but homicide investigators are looking into his death.

Sheehan had been the band’s tour manager for more than 30 years when he began working with the band, organizing tours and assisting with solo projects since 1982.

“We’ve lost a family member, we’re still taking it in,” Bono said in a statement on the band’s website. “He wasn’t just a legend in the music business, he was a legend in our band. He is irreplaceable.”

Sheehan has also worked tours with Led Zeppelin, Lou Reed, Patti Smith, The Damned, Siouxsie and the Banshees and Soft Cell.

“We’ve lost a family member, we’re still taking it in.”

“With profound sadness we confirm that Dennis Sheehan, U2’s longstanding tour manager and dear friend to us all, has passed away overnight,” Arthur Fogel, CEO Global Touring, Chairman Global Music Live Nation Global Touring. “Our heartfelt sympathy is with his wonderful family.”

U2 still plans to continue their 2015 iNNONCENE + eXPERIENCE Tour tonight (May 27th) in Los Angeles, sources close to the band confirm to the Irish Mirror.

“Everyone who works with the band is heartbroken, this has come as a huge shock but the view is that Dennis would have wanted the show to go on, but that could be subject to change,” the unnamed source claims.

The band has also teamed with Los Angeles rock station KROQ for an intimate private show at The Roxy Thursday night (May 28th) where patrons can only earn admission through the radio station.
