Marcos Diaz, a 30-year-old Hispanic father of three, was shot and killed on June 25, 2022, near his home in the McKinley Park neighborhood on Chicago’s Southwest Side. He worked two jobs and was attending school to become an electrician; family remembered him as a loving father and a good cook. The shooting occurred just around the corner from his residence.

Police arrested Diaz’s ex-girlfriend shortly after the killing on the belief she had orchestrated the attack, and witnesses said she was driving when a passenger in the back seat shot Marcos. She was released two days later after prosecutors declined to charge her with first-degree murder, and as of two months after the homicide no one had been charged. The family says two witnesses have cooperated, but investigators were still gathering forensic evidence.

Does anyone in McKinley Park have information about that night or about people who might have been in a vehicle near Marcos’s home on June 25, 2022?
