Desi D. Moore Sr., 31, of East St. Louis, Illinois, was shot on the evening of August 2, 2026, in the 5900 block of Mitchell Lane in Cahokia Heights. He was taken to Touchette Regional Hospital and pronounced dead early the following Tuesday by St. Clair County Coroner Calvin Dye Sr. Family described Moore as a loving, cheerful, outgoing man and a devoted father to seven children.

Cahokia Heights detectives identified a person of interest within an hour of starting the probe and focused on 23-year-old Terry T. Pittman Jr., also of East St. Louis. Pittman voluntarily surrendered the Wednesday after the shooting and was taken into custody. Investigators say the shooting grew out of a personal dispute; a fundraising page by Moore’s sister noted the man responsible was the brother of the mother of one of Moore’s children.

The St. Clair County State’s Attorney’s Office charged Terry T. Pittman Jr. with first-degree murder. The police chief called the killing tragic and senseless; the specifics of the argument that led to the shooting remain under investigation. Does anyone have information about Moore’s movements that night or about the dispute between the two men?
