A man who seriously beat a San Francisco Giants fan outside Dodger Stadium will be spend three more years in prison for a federal weapons conviction. Louie Sanchez was sentenced Thursday to six years in federal prison for possessing weapons as a felon. Judge Fernando Olguin ordered the sentence to take effect immediately, so he'll serve half of the sentence while finishing his eight-year term for the beating of Bryan Stow. Prosecutors had sought an additional eight-year federal prison sentence, while defense lawyers asked for an additional year in custody.
