Six people were killed and 21 were wounded in shootings across Chicago over the weekend.
• A robber and a clerk who tried to stop him were both killed Friday night inside a South Shore neighborhood grocery store. Police say Nicholas Williams walked into the El Barakah Supermarket near 73rd Street and Coles Avenue shortly after 6:20 p.m. and showed a handgun. Williams, 24, shot Ali Hasan, a 63-year-old worker at the store, in the chest and back, authorities said. Hasan — who had a firearm owner’s identification card and a concealed carry license — pulled a gun from his waistband and fired back, hitting Williams in the chest. The younger man, who lived in the neighborhood, ran from the store but collapsed about a block away and died, authorities said. Hasan, a Palestinian immigrant who lived in Berwyn, was taken to the University of Chicago Medical Center, where he was pronounced dead.
