VEVAY, Ind. (WOWO): A training exercise for a southern Indiana fire department has turned into a real investigation. Crews from a fire department in Vevay were doing a training dive on a private pond near Sellersburg, when cadaver dogs detected something in the water.

State Police divers made an initial dive but didn‘t find anything. A scan of the bottom of the pond did find what police think might be headstones.

Indiana State Police Sgt. Jerry Goodin says the divers will first focus on if the lake is a crime scene and will also document any headstones found and give that information to county officials to be recorded.

Goodin says it’s not uncommon for divers on training dives in the Ohio River to come across a car that had been stolen and dumped in the river, leading to a criminal investigation.
