A maintenance worker at a Milton-area campground died Tuesday night about 12 hours after he had a medical issue and fell into a swimming pool, Town of Milton Police Chief Tom Kunkel said.

The man worked at Lakeland RV Campground off Highway 59 and was in his late 60s. Town police were dispatched at 10:38 a.m. Tuesday after the man’s co-workers found him in the pool, Kunkel said.

The man was transported to Mercyhealth Hospital and Trauma Center, where he briefly regained a pulse. He later died at the hospital. Kunkel said he did not have an exact time or cause of death.

Kunkel expected the Rock County Medical Examiner’s Office to issue a news release soon.
