Smuggling Narcotics into a Correctional Facility Investigation 

March 20, 2026 – Riverside County Sheriff's Office officials report that in January 2026, the Riverside Sheriff’s Office Corrections Investigations Bureau began an investigation into members of the public working with inmates to smuggle narcotics into the Larry Smith Correctional Facility via the United States Postal Service. During the investigation, Sabrina Triguero, a 35-year-old resident of Las Vegas, Nevada, was identified as the suspect who sent narcotics to a Riverside Sheriff’s Correctional Facility via United States Mail. Nancy Dominguez, a 40-year-old resident of Rialto, was identified as the inmate to whom the narcotics were sent.

On Tuesday, March 17, 2026, with the assistance of the North Las Vegas Police Department’s SWAT Team and the North Las Vegas Regional Offender Drug Enforcement Operations (RODEO) Task Force, a search warrant was served at Triguero’s residence located in the 3000 block of West Lake Mead Boulevard in North Las Vegas, Nevada.

Triguero was located and detained without incident. During a search of the residence, over a half ounce of suspected methamphetamine and evidence related to the jail narcotics smuggling investigation was located. Triguero was arrested by the North Las Vegas RODEO Task Force for drug related charges in the State of Nevada and booked into the North Las Vegas Community Correctional Center.

The Corrections Investigations Bureau personnel seized evidence related to the jail narcotics-smuggling investigation. The investigation will be submitted to the Riverside County District Attorney’s Office for prosecution of Sabrina Triguero and Nancy Dominguez for smuggling narcotics into a jail and conspiracy.
This investigation was part of the Riverside Sheriff’s Office’s ongoing mission to prevent narcotics from entering our correctional facilities. The diligence of our deputies during searches, implementation of the nonintrusive sensor and scanning device known as the “OD Security Soter RS,” and comprehensive criminal investigations such as this are among several measures the Riverside County Sheriff’s Office has taken to combat the supply of narcotics into our jail system. Inmate education is a priority within our jails, and inmates are furnished with educational material and classes about the dangers of narcotics, with an emphasis on fentanyl, provided by the Detention Health Services Division of the Riverside University Health System.

This investigation remains ongoing. Anyone with information related to this investigation is encouraged to contact Investigator James Dickey at 951-955-7019 or Correctional Deputy Jerod Price at 951-922-7774.
