Officer Michael J. Michalski, 52, a 17-year veteran of the Milwaukee Police Department’s Special Investigations Division, was killed on the afternoon of July 25, 2018, while officers searched a house on the 2400 block of North 28th Street for a man wanted on multiple warrants. The team entered the residence and, after clearing the lower level, began searching the upper floor. Michalski was ascending a dim, narrow staircase with a bend that obscured the landing when a suspect, Jonathan C. Copeland Jr., who had concealed himself under laundry on the landing, opened fire with a .45-caliber handgun. Michalski was struck in the head; his body camera went dark and he was immediately incapacitated. He was taken to Froedtert Hospital and died of his wounds.

After the initial shots Copeland fired out a second-floor window at officers outside, then ran out of ammunition, discarded his pistol, announced his surrender and was taken into custody on the landing. Prosecutors charged Copeland with first-degree intentional homicide; he later pleaded guilty and was sentenced in May 2019. Did anyone in the neighborhood see activity at the house that afternoon or notice anything unusual before officers arrived?
