On January 14 at 1:16 a.m. officers responded to a 911 call of a domestic disturbance between a man and a woman in a motel room in the 12000 block of Aurora Avenue North. Officers arrived and could hear the 53-year-old female victim screaming for help. The 37-year-old male suspect refused to open the door for officers. Believing the victim to be in imminent danger, officers forced the door part way open when the suspect sprayed them with an unidentified chemical irritant. Officers heard the victim yell out that the suspect was armed with a knife as they backed away from the door. Officers then knocked out a window to get a visual on the suspect and victim in an attempt to isolate the suspect and rescue the victim. Officers saw that the suspect was armed with a knife and returned to the door, forcing it open. Officers gave the suspect repeated commands to drop the knife. The suspect advanced toward the officers while brandishing the knife. Officers were forced to shoot the suspect. Officers immediately provided first aid to the suspect and then called in SFD Medics who continued medical treatment. The suspect was pronounced dead at the scene. The victim was uninjured. Homicide and CSI Detectives responded to the scene and continue to actively investigate.
