Hired by then-Mayor Cory Booker in 2006, McCarthy served nearly six years as Newark police director before accepting an offer from Emanuel to assume leadership of the city’s 13,000-plus member police department in 2011.
McCarthy’s departure comes as Chicago city officials face intense criticism over the death of Laquan McDonald.
“Now is the time for fresh eyes and new leadership to confront the challenges the department and our community and our city are facing as we go forward,” Emanuel said at a Tuesday morning press conference.
McCarthy left Newark in 2011 as the police department was being accused of civil rights violations and police misconduct.
“Unconstitutional stop and frisk practices the use of excessive force against Newarkers and a broken internal affairs system that wouldn’t hold police officers accountable for wrongdoing, that the legacy he left in Newark and apparently that’s the legacy he was creating in Chicago.”
