Leticia Barrera was 32 when she was shot dead on October 31, 2007, in Chicago’s Back of the Yards neighborhood. The fatal shooting occurred around 6 p.m. on South Seeley Avenue as she returned from trick-or-treating with her three young children, ages 6, 4, and 2. Barrera, who was celebrating her birthday and was about 2 1/2 months pregnant, was struck in the head and died at the scene.

Investigators concluded she was not the intended target but a victim of ongoing gang conflict. Fear of retaliation initially kept many witnesses from speaking, but the community later provided leads and surveillance footage helped identify an 18-year-old, Orlando Avila, as a suspect; Avila was arrested and charged in March 2008. Barrera’s husband, Manuel Flores, took responsibility for their children, who received counseling after the trauma.

Did anyone in the neighborhood know Leticia or have information about the events that night?
