Lamont Alexander, 23, was killed on December 4, 2015, on the 4100 block of West 21st Street in Chicago’s North Lawndale neighborhood after a street confrontation in the late afternoon. Witnesses described a struggle that began in the street shortly before 4 p.m.; Alexander, who lived on the same block, was pronounced dead at 4:24 p.m. at the scene. Prosecutors say the confrontation began after 21-year-old Alonzo Redditt received a phone call alleging his sister had been beaten by her boyfriend, identified as Lamont Alexander.

According to charging statements, a fight broke out, another male briefly grabbed Alexander from behind, Redditt produced a handgun, struck Alexander during the struggle and then opened fire. Redditt allegedly fled on foot, grabbing the magazine and was picked up by a car about a block away; another man stayed and spoke with police, and witnesses provided a description used to identify the shooter. Investigators confirmed the time of death and ruled the case a homicide, and authorities later charged Alonzo Redditt with first-degree murder.
