DULUTH, Minn. — A Duluth woman is accused of stabbing her sister in the face with a piece of wood that had to be removed at the hospital.

Police say 26-year-old Stephanie Lynn Mattinas told investigators a fight started when she discovered her sister was having an affair with her boyfriend. Mattinas is accused of using an 8-inch wood molding fragment to attack her sister at a Duluth apartment Tuesday. Authorities say Mattinas used a baseball bat on her boyfriend.

She was charged Thursday in St. Louis County District Court with first- and second-degree assault. Mattinas’ sister told police she was punched about 15 times and stabbed with the wood. The Duluth News Tribune says she was transported by ambulance to St. Mary’s Medical Center where the piece of wood was extracted.
