EVERGREEN PARK, Ill. (AP) — Police say a woman working at a suburban Chicago supermarket was fatally shot. Law enforcement say her boyfriend has been arrested in connection to the slaying. The Cook County Medical Examiner’s Office has identified the victim as 21-year-old Jailene Flores, of Chicago. Evergreen Park Police Chief Michael Saunders says surveillance video inside the Mariano’s store in the southern suburb showed Flores walking away from her boyfriend before being shot multiple times around 9:15 a.m. Thursday. Saunders says Chicago police were able to track the boyfriend to that city’s North Side using expressway license plate readers and traffic cameras.
