Jason McCullough, 39, of Park Forest, Illinois, was shot and killed at about 5:45 p.m. on October 28, 2016. Officers responding to reports of shots fired at a home on the 200 block of Arcadia Street found McCullough suffering from at least one gunshot wound; paramedics pronounced him dead at the scene. Investigators described the incident as arising from a dispute between two adults who knew each other, not a random act.

Authorities say a lone suspect, 34-year-old Josiah Clark of Park Forest, was indicted on one count of first-degree murder and was located in Minneapolis, Minnesota, awaiting extradition. Investigators reported McCullough and Clark had been best friends and longtime roommates, and that McCullough had recently reported alleged misconduct by Clark to police and posted those allegations on Facebook; police believe the post may have motivated the killing. Three others were charged in connection with the case: Imanee Davis, 18, of Park Forest, and Jabari Davis, 38, of Chicago Heights, were indicted for aiding a fugitive, and Joshanda Clark, 35, of Glenwood, was indicted for obstructing justice.

Anyone with information about the killing is asked to come forward.
