Ronald Johnson

CHICAGO— A police officer will not be charged for shooting 25-year-old Ronald Johnson to death in an incident captured by a police car’s dashboard camera.

Cook county State Attorney Anita Alvarez announced on Monday that she is not charging Officer George Hernandez in the killing of Ronald Johnson, an African American man, on Oct. 12, 2014.

The dashcam video, which has no audio, shows Johnson running from several officers, according to reports. It also shows an officer firing, though Johnson is not on screen at that moment. According to Assistant State’s Attorney Lynn McCarthy, the video, when slowed down, shows Johnson had a gun in his hand.

Johnson’s mother is pressing charges to urge the city to release the dashcam footage and said the video clearly shows her son running away from the officers before he was shot.

Mayor Rahm Emanuel said the video should be released this week.

Last month, Alvarez charged another Chicago officer, Jason Van Dyke, with first-degree murder for killing 17-year-old Laquan McDonald by shooting him 16 times in October of last year. At the time, the official story was that the teen charged at police, but when the dashcam footage was finally released last month it showed McDonald walking away from the officer.
