Preracio Williams, 23, of the 15400-block of West Monterey Dr. in Oakbrook Terrace faces one count of first-degree murder and one count of attempted robbery with a firearm.
The June 8 murder took place at Fullerton Pawners at 5900 W. Fullerton when police say Williams and several other offenders entered the Northwest Side store and pulled out weapons, demanding money. The owner shot and killed one of the suspects.
The man killed was identified as Michael McMillan, 24, of 309 N. Menard Ave., according to a spokesman for the Cook County Medical Examiner's Office who said McMillan was pronounced dead at Our Lady of the Resurrection Medical Center at 1:17 p.m. June 8.
An autopsy June 9 determined McMillan died of a gunshot wound to the chest and his death was ruled a homicide, according to the medical examiner's office.
The slain suspect was convicted in 2006 of armed robbery and sentenced to boot camp, court records show.
Police sources said the owner of Fullerton Pawners Inc. shot the robber inside the store. Two accomplices -- one wearing a black backpack, ran away. One may have been wounded, sources said.
Police have recovered a revolver they believe the slain robber was wielding, sources said.
