Ottawa County officials are investigating after the body of a 69-year-old Spring Lake man was pulled from Petty's Bayou just after 10 p.m. Thursday, Nov. 3.

The Sheriff's Department says Joseph Thompson was apparently hooking a boat to a trailer with a family member before it happened.

They believe at some point, Thompson walked away and the other family member continued to work. After some time passed, the family member went looking for Thompson and found his body in the water.

Police are not sure how he ended up in the water or what led to the drowning.
