Ike Turner

Music pioneer Ike Turner's death last month at age 76 was caused by a cocaine overdose, according to the San Diego County Medical Examiner's office. "We are listing that he abused cocaine, and that's what resulted in the cocaine toxicity," said Paul Parker, chief investigator at the medical examiner's office. The medical examiner's office also listed hypertensive cardiovascular disease and pulmonary emphysema as "significant and contributing factors" to Turner's death, Parker said. Turner, whose musical accomplishments were overshadowed by his image as the man who brutally abused former wife Tina Turner, died Dec. 12 after years of drug abuse.
