Mary Wallace, a 13-year-old girl, was found shot outside an apartment door at the Cedar Hill Apartments in the Hickory Hill area of Memphis on the afternoon of April 1, 2022. Paramedics pronounced her dead at the scene; the shooting occurred around 1:45 p.m. and stunned the neighborhood.

Surveillance footage showed several males fleeing shortly after the shooting. Investigators identified 18-year-old Mikhael Thompson as a person of interest, obtained a search warrant, and arrested him. Officers recovered several firearms during the arrest, including one reported stolen in March. Thompson admitted involvement and said the shooting was gang-related. The affidavit states that shots were also fired into an apartment where three people, including two juveniles, were inside, and investigators determined one of the guns found in Thompson’s possession was the weapon used to kill Mary.

If anyone has information about Mary, that afternoon at Cedar Hill Apartments, or the people seen on nearby surveillance, please come forward.
