John Earl Irwin, 53, vanished from Cassopolis, Michigan after a night fishing on Birch Lake on July 21, 1995. He was described as having brown hair and blue eyes and was known to fish late; he also had a history of heart problems and struggles with alcohol. When he failed to return, a search was launched.

Searchers later found Irwin’s fishing boat washed ashore near a campground with the engine off. Inside were his wallet, a whiskey bottle, a shirt, a pair of pants, and fishing gear, but no sign of him. His truck was parked near the boat launch on the opposite side of the lake. A resident reported seeing an empty boat moving in circles on the lake about 2:00 AM the night he disappeared.

Divers spent eight days searching Birch Lake, which reaches about 100 feet deep in the center, but they recovered no further clues. Investigators found no evidence pointing to foul play and no sign that he chose to walk away; authorities considered accidental drowning plausible given his health and alcohol use, but his body was never recovered and the case remains unresolved.

Did anyone in the Cassopolis area have contact with John or recall the empty boat on Birch Lake that night?
