HARVEY, Ill. — Police in south suburban Harvey have issued an arrest warrant for first-degree murder in the death of a Canadian National Railroad security guard.

Rashad Williams, 24, of East Hazel Crest, should be considered armed and dangerous, police said at a news conference Thursday.

At about 4 p.m. Saturday, a woman called police to report someone was stealing her car. She was able to get into another vehicle and follow the man who stole her car. Police soon joined the pursuit, but when the suspect realized he was being followed, he crashed the car at 159th Street and Park in Harvey.

Tyrone Hardin, 38, was patrolling a nearby rail yard working security for a company contracted out to the Canadian National railroad. When the man in the stolen car bailed out and ran on to Canadian Railroad property, he tripped an alarm. Hardin was gunned down as he responded to the alarm. He was found with a gunshot wound to the abdomen and later died. The shooter took Hardin’s vehicle which was later found abandoned at 171st street in East Hazel Crest.

Some of the crime was captured on security camera.

Hardin, who lived in Merrilville, was a father of a 5-year-old and stepfather to four other children. He was at the rail yard as a  second job to earn extra money to buy his children presents for Christmas, according to his family.
