The Cook County State's Attorney's office said Friday that no criminal charges will come against Chicago, Illinois police officer Robert Rialmo, who fatally shot 19-year-old Quintonio LeGrier and mistakenly Bettie Jones, who was a grandmother standing by LeGrier during a fatal incident in 2015.

Many are outraged that an officer under investigation for fatal shootings was returned to street duty. Officials claim it was a mistake.

Two workers at Chicago's 911 center have been suspended without pay after failing to send police to assist Quintonio LeGrier, who called 911 three times for help on Dec. 26 from his father’s West Side apartment, reports the Washington Post.
