Have you seen Leo? Tips wanted in case of missing 59-year-old Waterford man with health issues

(WWJ) The Oakland County Sheriff’s Office is asking for help to find a missing Waterford man, who investigators say is at risk of a health crisis.

Leo Christopher Johnson. 59, was last seen on Monday, Oct. 14, while working on a sprinkler system at a home in the 1400 block of Spruce Drive near Commerce Road and Oakley Park, in Commerce Township.

According to investigators, Johnson walked away on foot shortly before 5 p.m., and was reported missing by his son.

He's diabetic, and family members are worried he may become disoriented because of low blood sugar levels.

Johnson was last seen wearing black pants, a gray hooded sweatshirt and a green baseball cap.

The OCSO Search and Rescue Unit, along with drones and tracking dog, searched for the missing man, but haven't been able to find him.

Anyone who has seen Johnson, or who has any with information, should call the Sheriff’s Office at 248-858-4950.
