Tyree Davis, 25, was shot and killed by Chicago police on January 4, 2020, after officers responded to a reported robbery in the 2600 block of East 79th Street. Officers were told the suspect had a knife and may have mental health issues. On arrival they saw Davis holding a knife in one hand and a glass bottle in the other; he fled and led officers on a foot chase while intermittently waving the knife and bottle.

A Taser was deployed and appeared to strike Davis, but he continued advancing toward officers. One officer fired three shots, striking Davis. He was pronounced dead at the scene; the Cook County Medical Examiner ruled the cause of death multiple gunshot wounds and the manner homicide. The Civilian Office of Police Accountability investigated; the State’s Attorney concluded the evidence was insufficient to charge the officers. The family has filed a lawsuit and says Davis’s mental illness was known to officers.

Did anyone in the neighborhood witness the chase or have video of the encounter that could shed light on what happened?
