Police are investigating the death of a 33-year-old Appleton woman found dead in a pond after responding to a report of an unsupervised 9-year-old child running naked in rural Shawano County.

Deputies were dispatched Wednesday to a property on Happy Lane in the town of Hartland and discovered the boy, who is autistic, and turned him over to Shawano County Human Services.

Two hours later, police responded to a report of a suspicious vehicle in the same area.

After a search, deputies found the boy’s mother dead in the pond, according to a news release.

Authorities are treating the death as an accidental drowning, though an investigation is underway.

No names have been released.
