Tom Petty Hospitalized After Being Found Unconscious in Cardiac Arrest: Report

UPDATE #2: CBS is reporting that Petty has died.

UPDATE: TMZ reports that when Petty arrived at the hospital he had no brain activity and a decision was made to pull his life support.

Tom Petty was rushed to the hospital on Sunday night (Oct. 1) after being found unconscious in his home, in a state of full cardiac arrest, according to reports.

TMZ cites law enforcement sources that say Petty is currently on life support at the UCLA Santa Monica Hospital, where he was taken by EMTs after they were able to get a pulse from the unresponsive singer/songwriter. The site says his condition is currently unknown but was "critical from the moment he was found," and that sources in Petty's camp "are clearly upset but not talking."

Best known for his work as leader of the Gainesville, Florida-based outfit Tom Petty and The Heartbreakers, Petty has been one of the most consistently successful rock stars of the last four decades, with 12 albums hitting the top 10 of the Billboard 200 albums chart since the No. 2-peaking Damn the Torpedoes first made him a superstar in the late '70s -- most recently 2014's Hypnotic Eye, improbably his first No. 1 on the chart. His Greatest Hits set, including such classic rock standards as "American Girl," "Refugee," "Free Fallin'" and "Mary Jane's Last Dance," has been certified 12x platinum by the RIAA.

Petty had just finished a 40th anniversary tour with The Heartbreakers, with its last date coming at the Hollywood Bowl in Los Angeles on Sept. 22. Billboard has reached out to Petty's camp for comment on the reports, but had not heard back as of press time.
