OLIVE TOWNSHIP, Mich. (WOOD) — A man charged with murder in his father’s death has pleaded guilty but mentally ill.

Kenneth John Boone pleaded guilty but mentally ill for first-degree premeditated murder and habitual offender fourth-degree on Sept. 3. He was originally scheduled for a trial on Sept. 14.

His father, James Kenneth Boone, was found dead at a home on Pawnee Drive in Spring Lake Township on Dec. 1, 2019.

Kenneth Boone had called 911 asking for assistance at 6:15 a.m. that day. That call was never passed to deputies. He called again at 7:24 a.m., saying he had hurt his father.

He was arrested after deputies found him walking down the road with a hammer, the weapon used during the attack.

His sentencing is scheduled for Oct. 4.
