MILL CREEK, Wash. (AP) — A judge in Washington state has sentenced a Mill Creek man to five years in prison after he held down a 12-year-old boy while his son stabbed him last year. The Daily Herald reported that Superior Court Judge Richard Okrent sentenced 44-year-old Martinez D. Mitchell on Tuesday after he was found guilty of third-degree assault last month in Snohomish County Superior Court. Police responded on June 10 to a stabbing at the Heatherwood Apartments. Police said the boy, who was not identified, was taken to Harborview Medical Center where he was treated for non-fatal injuries. Mitchell told the court he felt sorry for his “negligence and poor judgment.”
