Three men who were charged in the 2011 murder of Chicago Police Officer Clifton Lewis have called for a special prosecutor to take over the case and investigate allegations of misconduct by Cook County prosecutors.
The motion by lawyers for Alexander Villa, Edgardo Colon and Tyrone Clay comes weeks after prosecutors dropped all charges against Colon and Clay shortly before a hearing where detectives and prosecutors who handled the case had been set to answer questions about allegations they withheld key evidence from defense lawyers.
