Deputy Celestino Sanchez, 23, has been arrested and charged with manufacture delivery of a controlled substance. He is being held on a $10,000 bond.
Authorities say an inmate had arranged to have contraband delivered to an offsite location by a third party and deputy Sanchez.
On July 19, the sheriff's special crimes unit interviewed Sanchez, in which he admitted to being in possession of 3.6 grams of synthetic marijuana along with other items of contraband.
Sanchez has been employed with the sheriff's office since March.
