On�Saturday evening, police discovered a woman in distress, bleeding from her face and having difficulty breathing. The woman told officers that her boyfriend, identified as 31-year-old Robert Kelly of Oklahoma City, had become angry and assaulted her. She said the man punched her, kicked her in the head multiple times, choked her by pouring water over her, and stabbed her with a flat-head screwdriver up to 20 times on her back, arm, and hand.
