The acting head of the authority that investigates complaints against Chicago Police will speak about her plans to revamp the agency in response to outrage over a video showing the shooting of a black teenager 16 times by a white officer and the city's handling of the probe.

Sharon Fairley, appointed by Mayor Rahm Emanuel to reform the Independent Police Review Authority, will hold a news conference on Monday to outline "her vision for the agency." Agency spokesman Larry Merritt says in an email that she also will discuss staff changes made since she took the job in early December.

The Chicago Tribune reported that of 409 shootings investigated by the authority since its formation in September 2007, only two were found to be unjustified and both involved off-duty officers.
