The Placer County District Attorney's Office is expected to seek a new arraignment date for a Sacramento police sergeant accused of shoplifting in Roseville because prosecutors have not decided whether to charge him, authorities say. Sgt. John Castiglia was scheduled to be arraigned Tuesday in connection with a May 28 citation for allegedly shoplifting from a Roseville grocery store. However, prosecutors are reviewing the case and are expected to ask for a new arraignment date during Tuesday's proceeding, a district attorney's office news release states. Prosecutors hope to schedule a July arraignment, the release states. Castiglia, 48, is head of the Sacramento Police Department's financial crimes unit, with previous experience in the sexual assault and child abuse units.
