"On behalf of the Tom Petty family we are devastated to announce the untimely death of our father, husband, brother, leader and friend Tom Petty," the musician's longtime manager told PEOPLE in a statement late Monday night. "He suffered cardiac arrest at his home in Malibu in the early hours of this morning and was taken to UCLA Medical Center but could not be revived. He died peacefully at 8:40p.m. PT surrounded by family, his bandmates and friends."
The Los Angeles County coroner's office completed an autopsy on the late singer Tuesday, but the cause of death will require further examination, department spokesman Ed Winter told the Associated Press. According to the outlet, Petty had not seen a doctor in six months, no foul play is expected and toxicology results may take weeks to surface.
