Sources tell FOX 17 that Finnerty docked the boat and called his in-laws.
The Lake County Sheriff’s Department says Finnerty was having what the family described as an episode and say he was scared and wandered into the woods.
Finnerty led the Grand Valley State University Lakers to three national Division II championships from 2003 to 2006. Later, he spent time in the NFL with the Baltimore Ravens.
Anyone with any information are asked to call the Lake County Sheriff’s Department at 231-745-2712.
