Lonnell Holmes, 24, was shot and killed on October 22, 2017, in Chicago’s Austin neighborhood. He was found with gunshot wounds to the head and lower back in the 1000 block of North Lavergne Avenue at about 8:40 p.m. Cook County prosecutors say the shooting arose from a personal dispute: Holmes had reportedly taunted another man about the murder of that man’s teenage son.

Authorities identified the alleged shooter as 40-year-old Terrance Johnson. Witnesses at the scene pointed him out when he returned to the area, and he was found in a nearby house and taken into custody. Prosecutors say Johnson admitted the shooting in a taped statement; a flannel shirt he was wearing when arrested tested positive for gunpowder residue. Johnson was charged with first-degree murder and held without bond.

Holmes was an Orr High School graduate who attended Malcolm X College and worked at Walmart. Does anyone have information about Holmes, his routine that night, or the neighborhood that could help clarify what happened?
