Christopher Lavann Johnson was an 18-year-old from Chicago who was shot on a West Side street in the South Austin neighborhood on January 14, 2017 and died of his injuries two days later. He attended Perspectives Charter School and was remembered by family and friends as caring and outgoing, someone who knew how to make others smile.

His killing came during a violent period for the city, as 2017 brought hundreds of homicides and ongoing struggles with gun violence that disproportionately affected young people and neighborhoods like South Austin.

Does anyone who knew Christopher or witnessed what happened that day have information to share?
