Stefan Plummer, a 22-year-old African American man from Glenwood, Illinois, was fatally shot on December 27, 2019, in Harvey, Illinois. The shooting happened about 11:52 p.m. in the 14600 block of Loomis Avenue; Plummer was taken to Ingalls Memorial Hospital and pronounced dead less than an hour later. The Cook County Medical Examiner’s Office ruled the cause of death a gunshot wound to the torso and classified the death as a homicide.

Prosecutors say the shooting grew out of an argument over the quality of marijuana during a street sale. Nicholas Robertson, 20, was identified as the suspect; prosecutors allege Robertson retrieved marijuana from his home, returned to the vehicle, and then produced a handgun and shot Plummer. A witness identified Robertson by nickname, picked him from a photo lineup, and later said Robertson ordered a ride to an apartment in Riverdale after the shooting. Robertson was arrested and charged with first-degree murder; a videotaped confession was disclosed at a court hearing. He was denied bail and held pending trial.

Anyone who knew Stefan, witnessed the shooting, or has information about the events on Loomis Avenue that night is asked to come forward.
