MILL CREEK — Mill Creek police are asking for help finding a man who, along with his son, is suspected of assaulting a 12-year-old boy Wednesday evening.

Officers responded shortly before 11:22 p.m. to a report of a stabbing at the Heatherwood Apartments in the 13500 block of North Creek Drive, according to a Mill Creek police news release. There they found a 12-year-old boy who had been stabbed in the bicep, wrist and finger. He was transported to Harborview Medical Center in Seattle. His injuries were not believed to be life-threatening.

The boy told police that Martinez D. Mitchell, 43, ran up to him, punched him and held him in place. Mitchell’s son, also 12, then allegedly punched and stabbed the suspect.

The 12-year-old suspect was found at the apartment and was booked into the Denney Juvenile Justice Center in Everett for investigation of first-degree assault. A knife believed to be used in the attack was recovered at the scene.

The father fled before police arrived. According to police, Mitchell is 6 feet tall, weighs 200 pounds, and has black hair and brown eyes. He has tattoos, including on his upper chest and the left side of his neck. He was last seen wearing a black hoodie.

Police say he is known to frequent the Tulalip and Marysville area, as well as Tukwila. “Mitchell has a long criminal history and should be considered dangerous,” police said.

Tips about Mitchell’s whereabouts can be directed to 911. Anyone with additional information about the case is asked to call Mill Creek Detective Sgt. Stan White at 425-921-5762 or by email at investigations@cityofmillcreek.com.

This story has been modified to correct the name of the suspect, who was misidentified in the original news release.
