"EMTs were able to find a pulse when they found him, but TMZ reported that the hospital found no brain activity when he arrived. A decision was made to pull life support. CBS confirmed Petty's death. He was 66."
EDIT: Thanks to @erickhill and @protomyth for letting me know that he hasn't passed yet.
1:35 PM PT -- Sources tell us at 10:30 Monday morning a chaplain was called to Tom's hospital room. We're told the family has a do not resuscitate order on Tom. The singer is not expected to live throughout the day, but he's still clinging to life. A report that the LAPD confirmed the singer's death is inaccurate -- the L.A. County Sheriff's Dept. handled the emergency.
