John T. Anthony, 42, of Alton, Illinois, was shot and killed in the early hours of March 10, 2026. Police responding to multiple 911 calls found Anthony in the street in the 700 block of Oakwood Estates around 4:19 a.m.; he was taken to a local hospital and pronounced dead shortly after arrival.

A person of interest was taken into custody soon after the shooting and identified as 19-year-old Isaih R. Pierson of Alton. Police say witnesses identified Pierson as the shooter and that he confessed. A Cline C9 9mm handgun allegedly used in the shooting was recovered from an apartment. The Madison County State’s Attorney’s Office filed charges against Pierson: two counts of first-degree murder and one count of aggravated unlawful possession of a weapon, the latter alleging he was under 21 and not lawfully permitted to possess the handgun outside an apartment.

A 20-year-old woman, Gnyia D. Hardimon, was charged with obstructing justice after allegedly giving false information to investigators and was to be released with conditions; Pierson was ordered held in the Madison County Jail. Does anyone have information about Anthony’s last known movements in Alton or about the Oakwood Estates neighborhood that could help clarify what happened?
