A third man has been charged in the 2011 killing of Chicago Police Officer Clifton Lewis.
25-year-old Alexander Villa is charged with first-degree murder of a peace officer, aggravated battery and armed robbery with a firearm.
Officer Lewis was fatally shot during an attempted robbery, while working as a security guard at a convenience store in 2011.
Along with Edgardo Colon and Tyrone Clay, both arrested Jan. 7, 2012, he is charged with killing Officer Clifton Lewis on Dec. 29, 2011 during a botched convenience store robbery in the 1200 block of North Austin Avenue, police said.
Lewis, a tactical officer assigned to the Austin District, was working in the store that evening while off-duty, police said. In his eight years with the Chicago Police Department, he won 81 awards, including 70 honorable mentions and four department commendations, according to a CPD news release issued Friday.
