The Special Investigations Unit is a multi-agency drug enforcement task force that was started by a federal grant in 1974. What began as a small local agency task force with agents from the Stanislaus County Sheriff's Department and the Modesto Police Department to combat street level drug dealers, has grown to a task force that now includes police departments from Turlock, Ceres, Oakdale, Waterford, Newman and Hughson. Additionally, assigned to SIU are federal agents from the FBI, DEA, IRS and ICE.
