Police received the autopsy results earlier this week, said Lt. Bruce Morningstar of the Fruitport Township Police Department.
Michael Quigley, 54, died Nov. 18 in a wooded area in the 5200 block of Quarterline Road of Fruitport Township. He had been staying in a tent on the property for an unknown amount of time, Morningstar said.
Family members discovered Quigley was dead when they went to check on him.
Morningstar said the autopsy conducted at Sparrow Hospital in Lansing confirmed that no foul play was involved in the man's death.
