Dickerson was paying her cellphone bill at a store on the 5900 block of South Kedzie Avenue April 26 when a bullet flew through the window, fatally striking her in the head. Two of her three sons, ages 12 and 10, were with her at the time and tried to save her life. Witnesses said they saw two men shoot at a car as it drove by, and then ran into an alley to jump into an awaiting vehicle. A city ambulance was also hit by a bullet. Investigators say it was Bryant Mitchell, an admitted gang member, who fired shots at rival gang members nearby the store that day. Three individuals were wounded, but a fourth bullet struck and killed Dickerson. Mitchell appeared in bond court Tuesday as he faces a charge of first-degree murder and three counts of attempted murder. During a service at Norwegian American Hospital Tuesday, family and coworkers described Dickerson as a gregarious and beloved person who was admired by many for her kindness to others. She worked a pharmacy tech at the hospital for the last 14 years, and staff placed a plaque dedicated to her memory outside the pharmacy Tuesday morning. The Norwegian American Hospital Foundation has a fund used to help NAH employees and patients, including Dickerson’s family. The investigation into the shooting is still active. Police said they are questioning a person of interest Tuesday morning.
