DETROIT (AP) — A former police officer who was charged with killing his wife and children in 1975 has been convicted of murdering his second wife and 3-year-old son.

Paul Harrington, who was found not guilty by reason of insanity 25 years ago and served two months in a psychiatric hospital, now faces a mandatory sentence of life in prison without parole.

"We're glad this man will not hurt anyone else again," Chester Trail, a relative of Harrington's second wife, said.
