CAMP MEEKER (CBS SF) — Sonoma County sheriff’s deputies arrested a Camp Meeker woman Wednesday on suspicion of mailing an opioid drug to an inmate in the county jail.

Jail correctional deputies intercepted mail addressed to Trent Armstrong, 25, of Camp Meeker in west Sonoma County in mid-September, sheriff’s Sgt. Jason Lucas said.

Armstrong is serving a one-year term for auto theft and his extradition to Arizona to face drug charges there is pending. Deputies determined Armstrong’s girlfriend, Monica Genetti, 38, of Camp Meeker, mailed Suboxone to Armstrong over several months, Lucas said.

The drug is used to manage opioid abuse and withdrawal but also presents a high risk for abuse and addiction, according to Lucas.

Genetti also was arrested for furnishing a controlled substance, smuggling a controlled substance into a jail, conspiracy and possession of a controlled substance. She was booked into Sonoma County Jail but posted bail and was released, Lucas said.
