SANTA ANA, Calif.—A 42-year-old felon pleaded guilty Feb. 16 to stabbing a man in a robbery spree in Anaheim and was sentenced to eight years in prison.

Michael Angel Andrew Vera pleaded guilty to two counts of assault with a deadly weapon, four counts of robbery, two counts of attempted robbery and a count of resisting arrest, all felonies.

Mr. Vera appeared to be under the influence when he approached and robbed at least four people on La Palma Avenue at Harbor Boulevard around 7 p.m. June 28, Anaheim police Sgt. Jacob Gallacher said.
