An autopsy by the Pinellas-Pasco Medical Examiner's Office revealed Savage had an enlarged heart with severe atherosclerosis of his coronary arteries. He suffered only minor abrasions and bruising from the May 20 crash in Seminole, Florida. "He had sustained no trauma from that crash," said William Pellan, the medical examiner's office director of investigations. "So the crash had nothing to do with his death. He just happened to be driving when he had a cardiovascular event." Pellan added that he may have had a heart attack. He may have had some type of arrhythmia and his heart stopped beating, or his heart may have simply stopped beating. "We don't see evidence of it (a heart attack) because he died right away," Pellan said.
According to the toxicology report, Savage tested positive for alcohol and he opiate hydrocodone during the time of his death, but it is noted that they did not play a role in his death. A USA Today article notes that steroid use was not implicated in his cause of death.
