A 911 call came in around 11:40 a.m. Sunday for a man lying near his car without obvious signs of life.
Pronounced dead at the scene was 41-year-old Medhat "Mike" Sadiku of Normal. Coroner Beth Kimmerling said he was a father of three.
An autopsy on Sadiku Tuesday did not reveal a cause of death. Instead, Kimmerling said more testing has been ordered.
However, trauma has been ruled out and there were no obvious signs of life-threatening injuries at the scene.
