WATERTOWN, S.D. (AP) — Authorities say a Watertown man is dead after a bar fight last weekend.

Codington County Sheriff Brad Howell says 40-year-old Jeremy Buol died Wednesday. An autopsy was planned, and the sheriff says more charges might be filed once the investigation is complete.

The Watertown Public Opinion reports Buol was in a fight with a 28-year-old man at the South Fork Lounge in Watertown early Sunday. Buol was flown to a hospital in Sioux Falls.

The other man also is from Watertown and was arrested for simple assault. He's being held without bond.

The South Dakota Division of Criminal Investigation is assisting in the investigation.
