Off-duty police officer shot, killed in West Side convenience store

An off-duty police officer was shot and killed Thursday night during a robbery at a West Side convenience store where he worked as a security guard.
Two men walked into the M & M Quick Foods in the 1200 block of North Austin Boulevard in the Austin neighborhood about 8:30 p.m. and shot the officer, Clifton Lewis, several times with a "machine-type" pistol. They then grabbed his gun and star and fled.
Lewis, 41, an eight-year veteran assigned to the Austin District, was rushed to John H. Stroger, Jr. Hospital of Cook County, where he was pronounced dead. About 200 police officers joined Lewis' family at the hospital into the night.
Lewis was assigned to the Austin District's tactical team and his weapon wasn't recovered. Nobody is in custody
