A newly released video shows a Colorado Springs police officer brutally throwing a handcuffed 18-year-old woman to the hospital floor, smashing her face against the Memorial Hospital floor in 2013.So hard that it knocked her teeth out.The video will be part of a lawsuit that is being prepared on behalf of the woman against the department. In the video, Officer Tyler Walker, 29 at the time, is seen shoving the handcuffed woman, 18-year-old Alexis Acker, into a chair by hitting her in the stomach. Acker then kicks at the officer, likely because he just assaulted her and had no other means to defend herself. The officer is then seen immediately slamming the teen face first onto a hospital floor while she was handcuffed- knocking out two of her teeth. Aside from having two teeth knocked out, Acker suffered trauma to the face, head, teeth and jaw; migraine headaches, concussion, closed head injuries, memory and cognitive function problems, as well as post traumatic stress disorder.The incident took place after police were dispatched to Acker’s apartment after a report involving a gun. Acker was reportedly “intoxicated and verbally uncooperative with police,” and became “physically combative” when her boyfriend was arrested for outstanding warrants. The officers claimed that she was kicking at them and had to be pinned to a sofa. She was arrested on charges which included resisting arrest and assaulting a police officer.
