A 37-year-old American man facing trial over the killing of his wife at the Tokyo Family Court in 2019 was found not guilty Friday, with the ruling saying he couldn’t be held accountable because he had schizophrenia.

The ruling was handed down by the Tokyo District Court.

Jacob Wilson was on trial over the murder of his 31-year-old wife, Kyoko. The couple were in the process of getting a divorce. According to the ruling, he cut her throat with a knife at the entrance of the Tokyo Family Court on March 20, 2019. She was rushed to a hospital but died there about an hour later.
