Methamphetamine intoxication and a stroke killed one-time Survivor frontman Jimi Jamison, according to autopsy results released Tuesday.
"Acute methamphetamine intoxication'' contributed to a "hemorrhagic stroke of the brain,'' according to the autopsy findings. "Postmortem femoral blood toxicology showed a toxic to lethal combination of methamphetamine and a therapeutic concentration of its metabolite, amphetamine," the report stated.
The autopsy also noted Jamison, 63, had heart disease at the time of his death, including a 90-percent blockage of his coronary arteries. The coroner ruled the death accidental.
Jamison's son found him unconscious in his Memphis-area home on Sept. 1. He called 911, but the singer could not be revived. Initially, speculation pointed to a heart attack as the cause of death.
Jamison was connected to several Memphis bands over the years, but is best known as the singer for the power-rock band Survivor, which had hits in the 1980s including High on You and Eye of the Tiger, the theme song from the movie Rocky III, which was released before Jamison joined the band.
