Investigators have determined that soul icon Isaac Hayes, who died Sunday at the age of 65, was likely the victim of a stroke related to high blood pressure. Authorities revealed the cause of death on Tuesday, according to Reuters, based on the "Shaft" singer's health prior to his passing.
Shelby County Medical Examiner Dr. David Kraus reached the conclusion based on the fact that Hayes was being treated for high blood pressure and had suffered a nonfatal, but reportedly serious stroke last year. Hayes was found unconscious next to a running treadmill in his Memphis home on Sunday, and Kraus said there was no evidence that Hayes, who had once described himself as a "health fanatic," hit his head or suffered any trauma prior to his death.
"The Hayes family is comfortable with Dr. Kraus' recommendation to not conduct an autopsy," read a statement from the Shelby County sheriff. According to The Associated Press, no autopsy was performed. A public memorial service will be held August 18 at the Hope Presbyterian Church in Cordova, Tennessee.
"We are overwhelmed with the outpouring of support and love from Isaac's dear friends, colleagues and fans from every corner of the world, and we thank each and every one of them for their kind thoughts and prayers," the family said in a statement on the singer's Web site. "While he was an iconic figure to many, to us he was husband, father and friend. We will ever miss his love, wisdom, humor and the familiar comfort of his voice."
