A man with a shotgun tried to rob a South Side gas station, using a woman as a shield, but was shot dead by another man who then ran off Thursday night, according to Chicago police.

Tyrone Smith, 55, walked into the Citgo Food Mart in the 6700 block of South Cottage Grove Avenue at about 9:50 p.m. Holding a shotgun, he screamed, “Give me the money” several times and grabbed a woman in front of him, police said.

A man standing near the door pulled his own gun and shot Smith at least three times and then fled, police said.

Smith, who lived around the block, was taken to the University of Chicago Medical Center, where he was pronounced dead at 10:16 p.m., according to the Cook County medical examiner’s office.
