Original story: Rock star Tom Petty was found unconscious and rushed to the hospital Sunday night, according to a report from TMZ. According to their law enforcement sources, he is in critical condition.
Petty, 66, was reportedly put on life support at UCLA Santa Monica Hospital. An update from TMZ claims that "a decision was made to pull life support."
GuideLive's Brentney Hamilton wrote about Petty earlier this year ahead of a Dallas concert. She says, "Pop music history insists the band must have been completely out of place in late 1970s England. Rock was dead -- or so it seemed -- especially the extravagant machismo of luxurious guitar solos and Messianic frontmen that dominated radio airwaves in the '60s and early '70s. ... No matter. Tom Petty and the Heartbreakers were a hit both in the U.K. and on the subsequent tour of Europe in the late '70s."
