LOS ANGELES (AP) — A gunman who robbed or tried to rob 21 Trader Joe’s grocery stores throughout Southern California has been sentenced to 21 years in federal prison.

Gregory Johnson was sentenced Monday for a string of holdups last year in Los Angeles and Orange counties and the attempted robberies of two stores in Ventura and Riverside counties.

Prosecutors say Johnson already had a 2000 conviction for a Trader Joe's holdup and received a 12-year sentence. He and his son were arrested for the 2020 robberies after a witness supplied the license plate of their getaway car.

Johnson's son was sentenced last month to two years prison.
