Attorney General Loretta Lynch is expected to announce this week that the Justice Department will launch an investigation into the Chicago Police Department, officials familiar with the matter said. The inquiry will focus on whether the department routinely violated civil rights. The expected announcement follows the federal investigation into last year’s fatal shooting of 17-year-old Laquan McDonald, who was shot and killed by an officer. Recently released dashboard-camera footage of the incident incited protests, prompting calls for a federal investigation and culminating with the firing of Police Superintendent Garry McCarthy. Officer Jason Van Dyke was also charged with first-degree murder in the shooting. Scott Ando, the director of the Independent Police Review Authority, also resigned Sunday evening, just hours after news of the impending investigation, according to a press release from Mayor Rahm Emanuel.
