Two 15-year-olds killed in gang-related shootings in Santa Rosa and Chicago.

A 15-year-old boy who was shot in a gun battle in Santa Rosa died at a local hospital on Sunday. The shooting occurred when an argument between two small groups, consisting of teenage boys and men in their 20s, escalated. The police believe the involved males were gang participants, and detectives are trying to determine if this shooting is related to last week’s homicide. The Santa Rosa Police Department is bringing back its gang crimes team, with a focus on reducing street violence.
