William Porter Jr., a 42-year-old African American man, was shot and killed on July 9, 2020, around 4 p.m. at G&P Confectionery, a store he owned at 1332 Bond Avenue in East St. Louis, Illinois. The East St. Louis Police Department opened a homicide investigation and the Illinois State Police Division of Criminal Investigation, Zone 6, joined the inquiry. No immediate arrests were made and the case remained unsolved as investigators sought public tips and offered anonymity and potential rewards through CrimeStoppers.

Porter’s death occurred during a violent stretch in the city: three other people were shot and killed in separate incidents between July 9 and July 12, 2020 — Hardy M. Burns (37) on July 10, Tony Townsend (41) on July 11, and Terrill D. Mason (30) on July 12. Each killing was treated as a separate incident with no apparent connections reported.
