(UPDATE)– The Iowa DCI reports three people were found dead this morning at the Maquoketa Caves State Park campground.

Officers found a camper was unaccounted for — and following a search of the area, they found the body 23-year-old Anthony Orlando Sherwin. Sherwin appears to have suffered a self-inflicted gunshot wound, and there is no danger to the public.

Multiple news media reports indicate authorities are searching for a suspect after a shooting at the Maquoketa Caves State Park early this morning.

An employee told the Quad City Times the Maquoketa Caves State Park was locked down by police after a shooting around 8 a.m. The campground was evacuated. A Facebook post from a Christian camp about four miles away from the state park indicated children had been evacuated from there as well.
