HARVEY, Ill. – The manhunt continues for a man considered armed and dangerous, after he shot and killed a railroad security officer in the South suburbs.

According to his family, 38-year-old Tyrone Hardin of Merriville, Indiana was working one of his two armed security jobs at Canadian National’s Markham rail yard yesterday when he was alerted to an intruder. Hardin went to investigate and encountered the armed suspect. There was an altercation, and Hardin was shot.

It all started around 4 p.m. Saturday afternoon in Harvey, when the would- be shooter stole a woman’s car from a gas station at 159th and Halsted. That woman managed to trail the suspect in another car while on the phone with dispatchers. Police think the man got nervous when he heard their sirens closing in, and crashed into a viaduct at 159th and Park. He then got out and ran away on top of the viaduct toward the rail yard, where he encountered Hardin. Police believe there were at least eight to nine shots fired, and Hardin’s family said he was hit twice.

The shooter took off in Hardin’s security car, and eventually ditched it at 171st and Park in East Hazel Crest, and continued fleeing on foot. Police warn residents of Hazel Crest, East Hazel Crest and Markham to be on vigilant and report anything suspicious.

“I can not confirm or even deny whether the suspect was injured in any magnitude, but I will say, we collected a lot of data. We’ve looked at all the surveillance tapes in the area and we’re continuing to do that to help find any little thing that can help take us further down the road,” said Harvey Spokesperson Sean Howard.

Hardin was taken to Advocate South Suburban Hospital where he was pronounced dead. He’s being remembered as a hardworking husband and father of six.

CN Railway Police, Illinois State Police, East Hazel Crest Police, Hazel Crest Police and Markham Police are assisting the Harvey Police Department. Police in the south suburbs are now urging the gunman to come forward to turn himself in.

“He just needs to be caught and brought to justice,” said Hardin’s stepson, Jawaun Thurston.

Hardin was not an employee of the rail yard, but a contracted security officer. In a statement, CN Railway said:

Multiple police agencies continue to investigate the shooting death of a security officer who was tragically killed Saturday evening while on duty at the CN railroad yard in Harvey. The guard worked with a private security firm that assists CN Police. We would like to express our sincere condolences on this tragic loss to the guard’s family, friends and co-workers.
