De Andre Adams, a 25-year-old Black man from Chicago, was shot and killed on February 7, 2023, in the South Shore neighborhood. Around 1:45 p.m. in the 1600 block of East 78th Street, bullets struck his head and left arm; he was pronounced dead at the scene. Early reports said no one was in custody.

That same morning, about 9 a.m., Adams began an Instagram Live while walking to his mother’s house to do laundry. A friend, 24-year-old Edwin Sims, met him and they returned to Adams’s apartment with the livestream still running. Prosecutors say the livestream captured a gunman standing behind Adams and firing several shots into the back of his head and body; the feed then showed the shooter leaning down with a gun and ending the broadcast. Surveillance video allegedly showed the assailant tossing both of the victim’s phones into a building trash can before fleeing.

Detectives arrested Sims outside his home the following week and recovered from his waistband a loaded handgun with an automatic-fire switch; prosecutors said that gun was not the murder weapon. He denied killing his friend but admitted being in the bedroom and wearing the same distinctive sweatshirt seen on the shooter. He was charged with first-degree murder, unlawful use of a machine gun, and armed robbery with a firearm and ordered held without bail.
