A manhunt continued late Monday morning for a suspect in the weekend fatal shooting in Harvey of a railroad security guard who is being remembered by his employer as "a true professional."

Tyrone Hardin, 38, was fatally wounded Saturday while working on Canadian National Railway property in the 15800 block of West Avenue, officials said.

The Cook County medical examiner’s office listed Hardin’s address as being in Riverdale. A person who answered the phone at a family member’s home Monday said Hardin had been living in Indiana.

The suspect who police believe killed Hardin remained at large Monday, said Harvey spokesman Sean Howard in an email at 10:45 a.m.

Hardin was pronounced dead at 6:25 p.m. Saturday at Advocate South Suburban Hospital, according to the medical examiner’s office.

Hardin had been working as a security guard for the Hazel Crest company Gideon’s 300 Security Services Inc., for a year and a half, according to a statement from company president, Lawrence Moore. The firm was contracted by Canadian National.

Moore called Hardin "a true professional dedicated to his duties" and said "his loss will be deeply felt."

Harvey police had been pursuing a stolen vehicle when it crashed in the area of 159th Street and Park Avenue. The driver got out and ran on top of a viaduct, which led to an area belonging to Canadian National, Howard said. The driver then came in contact with Hardin and shot him several times in the abdomen, the Harvey spokesman said.

After shooting the security guard, the man got on a railroad car headed south, Howard said. Around 171st Street, he jumped the rail car and ran away from the authorities.
