Belding Police Chief Dale Nelson released preliminary results from an autopsy of Devon Morrison, whose body was found Monday by searchers near the Ashfield Street bridge in Belding, about 25 miles northeast of Grand Rapids.
The boy was last seen Saturday as he headed for the Flat River from his nearby home with a fishing pole. He was a fifth-grader at Woodview Elementary School.
"My world has crashed," said Devon's mother, Shauna Smith.
Smith said her son was "all boy."
"He liked cars and trucks and heavy machinery. Fishing, sports, dirt, bugs," she said.
Devon's disappearance prompted an extensive search. Police have said Devon would regularly fish alone at the river.
