SHEBOYGAN FALLS, Wis. (CBS 58) -- A Sheboygan Falls woman was sentenced to life in a mental health institution for killing her 8-year-old son. 

Authorities say Natalia Hitchcock admitted to suffocating her son Oliver in March of 2022. 

Court documents allege Natalia, who is from Russia, was worried about the ongoing invasion of Ukraine. In the criminal complaint, a witness stated that those worries may have affected her mental state before strangling Oliver.

Natalia Hitchcock had no prior criminal history.

In court on Thursday, May 11, the court found Hitchcock guilty but not guilty due to mental disease/defect.
