Source: Chicago police civil rights probe coming

CHICAGO (AP)-- A law enforcement official says U.S. Attorney General Loretta Lynch is going to announce a civil rights investigation of the Chicago Police Department.

The official says Lynch will make the announcement with the U.S. Attorney in Chicago, Zachary Fardon, at a news conference in Washington on Monday morning. The official is not authorized to speak about the announcement and would only speak to Associated Press reporter Don Babwin on condition of anonymity.

The announcement comes nearly two weeks after the city released the explosive video of a white Chicago police officer shooting black teenager Laquan McDonald 16 times and killing him.

Officer Jason Van Dyke has been charged with first-degree murder and Mayor Rahm Emanuel forced Police Superintendent Garry McCarthy to resign.

Emanuel also says the city will release of another video that shows an officer shooting and killing a black man. Cook County State's Attorney Anita Alvarez, whose office charged Van Dyke, has said she's launched a criminal investigation into the shooting.
