Lynch to announce Chicago findings

The U.S. Department of Justice plans to announce it has found that the Chicago Police Department engaged in a pattern or practice of conduct that violated the U.S. Constitution, two sources with knowledge of the investigation said.

U.S. Attorney General Loretta Lynch will make the announcement Friday. It was not clear how sweeping the conclusions of the 13-month investigation would be, but the sources said the Justice Department found constitutional abuses of citizens by Chicago police. The investigation was launched in December 2015 amid the fallout over the release of video showing the fatal shooting of black teenager Laquan McDonald. At that time, Lynch said the probe would focus on the Police Department's use of force — including whether there were racial, ethnic and other disparities in how force was used.
