Swimmer found dead at Polk County lake

Polk County detectives are conducting a death investigation after a man was found dead at Lake Eloise.

On Sunday, four adults were boating out on the lake, and in order to cool off, one of them jumped into the water.

When his friends could not find him shortly after, they called the authorities. After a search of the area, his body was found.

Detectives are still trying to figure out what happened.
