Sean Chaney, 24, was shot and killed on March 26, 2023, inside an apartment building near Popuch Park in Milwaukee. According to a criminal complaint, the incident began when Chaney arrived at the building demanding to retrieve his property; a resident called 911 saying he had broken into her apartment and was harassing her. Chaney also called 911 claiming he was there to collect belongings and had been denied access. Police responded earlier in the evening and cited him.

Later that night the same resident called police again saying Chaney had returned with another person and was refusing to leave. Just over an hour after that call emergency responders were alerted that Chaney had been shot. He was found in a hallway with two gunshot wounds to the chest and reportedly had a full-sized AR-15 rifle tucked into his waistband. David Simms, 25, who was present, admitted to shooting Chaney and was charged with first-degree reckless homicide; he said he acted in self-defense after both men pointed firearms at each other. No other arrests have been reported.

Are there witnesses or neighbors who saw what happened that night or who can clarify the sequence of events?
