Melvin L. Hayes, a 39-year-old African American man from St. Louis, was found shot to death behind an abandoned home in Alton, Illinois, on September 6, 2014. Authorities determined his death was a homicide and concluded he was killed during the course of an armed robbery.

Madison County charged two men in connection with the killing. Antione D. Parker, 33, of Belleville, was arrested September 9, 2014, and booked on three counts of first-degree murder, one count of armed robbery and one count of armed violence; prosecutors said he was not the gunman but held him accountable for his role. Bruce D. Bradley, 38, of Fairview Heights, was charged September 18, 2014, with similar murder counts plus armed robbery, armed violence and unlawful possession of a weapon; authorities continued to seek him after the charges.

Parker pleaded not guilty and was held on $1 million bond. Are there witnesses or neighbors who remember activity near the abandoned house on or around September 6, 2014?
