CHICAGO (AP) – A man has been charged in the stabbing death of a Chicago drug store employee as she stocked shelves over the weekend. Authorities say 32-year-old Olga Marie Calderon, the mother of two, was grabbed around the neck by 18-year-old Sincere Williams early Sunday at a Walgreens store and stabbed several times as she tried to push him away. Police Cmdr. Eric Winstrom said Tuesday investigators reviewed private and city surveillance cameras to track Williams back to the apartment complex where he lives. Winstrom says Williams discarded the knife and his clothing in a nearby yard after the attack. Williams is charged with first-degree murder and has a court hearing scheduled for Wednesday.
