St. Louis police identified the 52-year-old man killed by an officer after a reported fast-food restaurant robbery.

Police on Monday named Crayton West was killed during what they said was a Sunday evening armed robbery at a Kentucky Fried Chicken restaurant. The 42-year-old officer has not been identified.

West was shot after reportedly pointing a handgun at the officer. A witness flagged down the officer at a nearby gas station.

The St. Louis Post-Dispatch (bit.ly/1RQ0Lc4 ) reports that West is listed on Missouri's sex offender registry for a July 1980 robbery in which he sexually assaulted a 16-year-old male. West was also sentenced to 60 years in prison for a string of fast-food restaurant robberies in 1986.

West's mother told the newspaper that he was released from prison in January 2014.
