Mario Leyva, a 38-year-old Hispanic man, was found with multiple gunshot wounds in an alley in the 3300 block of South Western Avenue in McKinley Park, Chicago, on June 30, 2022, at about 10:15 p.m. He was taken to Stroger Hospital and pronounced dead.

Police arrested 37-year-old Sebastian Aguilar on August 9, 2022, in the 2400 block of South Christiana Avenue. Aguilar was charged with first-degree murder; authorities say he shot Leyva in the cheek and neck. Aguilar was scheduled to appear in bond court after his arrest.

The shooting and the later charge have had a strong impact on the local community and on Leyva’s family and friends, who continue to mourn. Does anyone have information about Leyva’s movements that night or anyone who might have witnessed the alleyway incident?
