Ricardo C. Mendez-Bucio was an 18-year-old Hispanic male shot and killed on August 13, 2015, in the Brighton Park neighborhood on Chicago’s Southwest Side. He was the front-seat passenger in a vehicle stopped at a red light on South Western Avenue, waiting to turn left onto 47th Street, when a 17-year-old male, identified as Eliseo Acosta, approached the car with another gang member, flashed gang signs and began yelling. Ricardo and the other occupants raised their hands in a gesture of surrender. Acosta walked up to Ricardo’s side, produced a handgun and fired a single shot that struck Ricardo in the chest. The driver took Ricardo to Stroger Hospital, where he was pronounced dead shortly after arrival.

Witnesses identified Acosta as the shooter; he was arrested at his home in the Ford City neighborhood two days later and charged as an adult with first-degree murder. At a court appearance, Cook County Judge Peggy Chiampas denied bail and ordered Acosta to have no contact with gang members, the victim’s family, or witnesses, including via social media. Ricardo’s family, especially his father Ricardo Mendez Sr., expressed deep grief and planned to move out of the Back of the Yards neighborhood because of safety concerns.

What information might someone with knowledge of that intersection, the vehicle, or those who were in the car before the shooting be able to share?
