Pat Nabong/Sun-Times The Chicago police officer who shot and killed Anthony Alvarez during a foot chase earlier this year in Portage Park has been stripped of his police powers — an action that had been recommended by a civilian oversight board back in April. Officer Evan Solano was relieved of his duties for the duration of an ongoing investigation into the shooting by the Civilian Office of Police Accountability. COPA had recommended that the department take such action but Mayor Lori Lightfoot initially balked at the idea. Police Superintendent David Brown declined to comment on Solano at an unrelated news conference on Monday.
