Roseville, Calif.- On Saturday, October 11, Roseville Police detectives, working with investigators from the California Department of Corrections and Rehabilitation, arrested a 63-year-old Roseville woman on suspicion of smuggling drugs into San Quentin State Prison to be sold to inmates.

Several weeks ago, Roseville Police Vice and Narcotics Enforcement Team (VNET) detectives began investigating allegations that a Roseville woman was taking drugs into San Quentin.   In the course of the investigation, conducted in collaboration with CDCR’s Office of Correctional Safety’s Special Service Unit and Homeland Security Investigations’ Customs and Border Protection Air Unit, detectives gathered evidence that the suspect regularly drove from Roseville to San Quentin with illegal drugs, which she took into the prison’s group visiting area and gave to an inmate during visits.   The inmate and his co-conspirators are suspected of selling the drugs to other inmates.  The Roseville woman had originally become acquainted with the inmate through a pen-pal program.

On Saturday, October 11, VNET detectives followed the woman from Roseville to San Quentin, where they contacted her and confiscated illegal drugs.

Marie Kathrine Allison, age 63 of Roseville, was arrested on suspicion of transporting heroin, methamphetamine and marijuana for sale, conspiracy, and bringing controlled substances into  a state prison.  She’s being held in the Placer County Jail on $85,000 bail.  Similar charges are being forwarded on three San Quentin inmates who are suspected of being her co-conspirators.

This case was a great example of local, state and federal law enforcement agencies working together to keep dangerous drugs off our streets and out of correctional facilities.
