Officer Jason Van Dyke, a 13-year veteran of the force, shot 17-year-old Laquan McDonald, who was holding a knife and had stabbed the tire of a police car. Officers had him surrounded on a city street and were waiting for someone to arrive with a stun gun to subdue him.

His name will appear on a sex-offender registry sent to neighbors, schools, and victims.
