Tyrone Hardin, 38, was shot around 7 p.m. by a man police say also stole two cars—including the guard's.
Prior to the shooting, the man is believed to have stolen a Harvey woman's car, crashing it shortly afterward. He fled up onto train tracks, where he encountered Hardin. The suspect then fired at least 12 shots, one of which struck Hardin in the stomach. He then stole Hardin's car, later abandoning it in the 100 block of 171st Street.
The victim was taken to South Suburban Hospital in critical condition. He later died from his wound.
The Negro suspect was last seen wearing a black sweatshirt and blue jeans, ABC7 reports. Harvey police and multiple other agencies are searching for the suspect, who is considered to be armed and dangerous.
