SAN FRANCISCO (AP) — A judge has denied bail to a key figure in a sweeping organized crime and public corruption case in San Francisco.

U.S. Magistrate Nathanael Cousins turned down Raymond “Shrimp Boy” Chow’s request to be released from jail on Wednesday. Several witnesses testified during a hearing that Chow has turned his life around since he was released early from prison for racketeering charges in 2003.
