Authorities say an eastern Missouri woman has drowned in Big River at a state park in Washington County.

The St. Louis Post-Dispatch reports that the incident happened Tuesday afternoon, when 67-year-old Monica Boyer was wading in the river near the Washington State Park boat access.

Investigators believe Boyer waded into deeper water, where she slipped, went under the water and did not resurface.

The Missouri State Highway Patrol says Boyer's death was the latest of 10 in waterways across the state in the first two weeks of June.
