Authorities say a 39-year-old Wixom man who was wading while using a metal detector to search for valuables has drowned in Saginaw Bay at the Caseville County Park beach.
The Huron County sheriff's department says Thomas E. Weaver drowned Saturday. The department says Weaver was wading in about 4 feet of water when he called for help several times and went under the water.
The Bay City Times reports about 100 people formed a human chain to walk through the water after Weaver disappeared.
The sheriff's department says Weaver was found about 20 minutes after he went under and was taken to an area hospital, where he was pronounced dead.
Caseville County Park is located in Huron County in Michigan's Thumb region, about 110 miles north of Detroit.
