SMITHVILLE, Tenn. (AP) — Authorities are investigating a drowning at Center Hill Lake in DeKalb County.

According to media reports, a man drowned in an area of the lake near Cove Hollow Marina on Saturday. The TWRA said Stephen R. Morris, 57, of Collierville, Tenn., is the victim. He reportedly died when he fell out of his personal watercraft that was tied to a house boat on the lake.

Authorities began searching for his body around 4 p.m. and found it a few hours later about a mile-and-a-half downstream. Investigators say Morris may have suffered some type of medical situation to cause him to fall off the watercraft.
