Christopher D. Green, 41, a white man, was found shot in the roadway on the 2000 block of Agnes Street in Alton, Illinois, in the early morning hours of June 1, 2025. Police were dispatched at about 5:51 a.m.; officers and Alton Fire Department paramedics tried life-saving measures and transported him to a nearby hospital, where he was pronounced dead.

Detectives quickly identified a person of interest who knew Green and requested Illinois State Police Crime Scene Investigators as they processed the scene and canvassed witnesses. Within hours a 17-year-old boy from Alton was detained; authorities said the teen and Green knew one another and did not release the juvenile’s name because of his age. Public notices and memorial listings confirmed Green’s name, age, and date of death.

The investigation remained active and centered on known associates rather than a random attack. If anyone saw activity on Agnes Street the morning of June 1, 2025, or has information about Green’s movements before the shooting, please share what is known with investigators.
