One of 2024's most viral Michigan moments hit social media in June. A couple in Marysville was working on their indoor jacuzzi when they were shocked to discover a 20-foot water-filled pit under their home. While speculation ran wild in the video's comments, the homeowners themselves may have solved the mystery, and it may involve booze smuggling.

The Discovery of a 20-foot Room Under a Marysville, Michigan Home

If I found a secret water pit under my home, I'd be creeped out and automatically assume it was filled with creatures waiting for that room to be unsealed. However, CBS Detroit spoke with Trevor and Hayley Gilmartin, the homeowners, days after the discovery, and they seemed unphased by the experience.

Exploring the Underground 'Swimming Pool'

Trevor is an avid scuba diver, so his first thought was, "I want to swim in it." Well, he did after having the water tested, and while some answers were found, new mysteries and theories were discovered when Trevor took his equipment into the secret pit.

It was then he discovered a wooden wall that could lead to another room that may help in solving the mystery. Commenters in the videos suggested draining the water and using the room as a basement. Still, after 8 hours of attempting to do so, they determined the water was coming from the river located behind the home.

In a third video update posted on the couple's TikTok account, @haygill99, new footage is revealed, as is the theory that the secret room was used to smuggle booze during prohibition. Oh, and that wooden wall? Trevor speculates that it may lead to a tunnel that ends at another structure found in the river.

Will 2025 be the year they solve the mystery entirely? We might have to wait for warmer weather if a river dive is required. Fingers crossed.
