Authorities are searching for a woman after finding the corpse of a man in a freezer inside her southwest Missouri home.

Sixty-seven-year-old Barbara Watters, of Joplin, was charged Wednesday with abandonment of a corpse. Police said in a Facebook post that the man whose body was found Tuesday hasn’t been identified. Police located the body after learning Monday during an unrelated arson investigation that a body might be inside her home and obtaining a search warrant.

Police Chief Matt Stewart told The Joplin Globe that there were no obvious signs of foul play. An autopsy is needed to determine how the man died. Police haven’t indicated how long the body may have been in the freezer.
