MARTINEZ -- A Pittsburg man found to be insane when he stabbed to death a housemate in 2012 was committed Tuesday to Napa State Hospital by a Contra Costa judge.

Abraham Duarte-Gonzalez, 22, was convicted by a jury in March of second-degree murder in the death of Marisol Flores, a conviction that carried a sentence of 15 years to life plus one year for a knife enhancement. The same jury later ruled that Duarte-Gonzalez, who is diagnosed with schizophrenia, was legally insane at the time of the crime.

According to a forensic psychiatrist who examined Duarte-Gonzalez and testified at his trial, the defendant killed Flores because he believed she was practicing witchcraft on him.

Judge Patricia Scanlon ordered Duarte-Gonzalez to the Napa facility for 16 years to life, or until such time it can be proved his sanity has been restored.
