Latest: Chicago releases more surveillance video in shooting

Chicago officials have released surveillance footage from businesses near where the fatal shooting of a black 17-year-old by a white police officer took place.

The Chicago Tribune reports (http://trib.in/1QjabKy ) officials on Thursday evening released a number of recordings in response to public records requests by the newspaper.

Cook County State's Attorney Anita Alvarez has said her office is investigating possible criminal charges in the case.

Durbin said Thursday in a news release that he spoke with Attorney General Loretta Lynch and requested an investigation by the U.S. Department of Justice's Civil Rights Division.

Durbin says the fatal shooting of a black teen 16 times by a white officer, video of which was released last week, is one of a series of "troubling events."

Emanuel sent out a statement Thursday, a day after saying that a federal civil rights investigation into the police department's tactics would be "misguided" because the U.S. Attorney's office in Chicago already is investigating.

Democratic presidential candidate Hillary Clinton and Illinois Attorney General Lisa Madigan are among those calling for an investigation by the U.S. Department of Justice's Civil Rights Division to determine whether the police department's practices violate federal and constitutional law.

Emanuel says he trusts federal officials "to make the right decision" and is "open to anything" that would restore trust in the city's public safety efforts.
