CHICAGO (CBS) — Police are searching for a man who shot and killed a Canadian National Railroad contracted security guard and stole two vehicles Saturday evening in south suburban Harvey.

About 4 p.m., a woman called police to report a man stealing her car, according to Harvey city spokesman Sean Howard, who initially said the call was made about 7 p.m. The woman was able to get in another car and followed the man while speaking with police. After hearing police sirens and realizing he was being followed, the man crashed the stolen car near 159th Street and Park.

The man then ran towards the viaduct on the nearby railroad where he saw the Canadian National Railroad security guard working at an intermodal facility in a vehicle, said Howard and CN spokesman Patrick Waldron.

The guard, 38-year-old Tyrone Hardin, was found shot in the abdomen and was taken to South Suburban Hospital where he was pronounced dead at 6:25 p.m., according to Howard and the Cook County medical examiner’s office. He lived in the 900 block of East 133rd Street in Riverdale.

The shooter stole Hardin’s vehicle, but then abandoned it in the 100 block 171st Street in East Hazel Crest, according to Howard.

The man was seen wearing a black sweatshirt and blue jeans, said Howard. Harvey police and other agencies were conducting a manhunt for the man, who was considered armed and dangerous.
