Woodland, CA – November 21, 2025 – On November 18th and 19th, 2025, Yolo County law enforcement conducted compliance checks and address verifications on over 300 registered sex offenders. “Operation Vigilance” is a program that started 16 years ago with the goal to protect Yolo County citizens by ensuring that those who must register as sex offenders, who live in the County, are complying with all laws and applicable parole or probation directives.
Over 60 law enforcement personnel from the California Department of Corrections and Rehabilitation, Davis Police, Yolo County Probation, Woodland Parole Unit, California Department of Justice, Yolo County District Attorney’s Office, Yolo County Sheriff’s Office, West Sacramento Police, Winters Police, and the Woodland Police participated in this joint operation. Additionally, the Yolo County IT GIS Division provided key support to the operation.
Many of the individuals who are required to register were previously convicted of rape, child molestation or possession of child pornography. During the operation, law enforcement personnel attempt to visit and verify the address of every registered sex offender with a physical address in Yolo County.
One unique aspect of “Operation Vigilance” is that while officers are making the home visits, forensic examiners search the computers, smart phones, and other digital storage devices for potential violations. Computer forensic investigators from the Yolo County District Attorney’s Office High Technology Unit and examiners from other participating agencies worked together to conduct these specialized searches. Additionally, the California Department of Corrections and Rehabilitation provided five Agents with canines trained specifically to detect electronics to enhance these searches. During the operation, 58 electronic devices were searched, and an additional 4 electronic items were seized for further forensic examination.
Approximately 5% of registered sex offenders within Yolo County were found to be out of compliance with their sex offender registration requirements which will result in additional investigation by law enforcement. Five offenders on parole/probation were arrested for various violations by officers participating in this operation.
Yolo County Sheriff Tom Lopez commented; ““Operation Vigilance demonstrates how Yolo County agencies work together to protect the public. I am grateful for the skilled, committed professionals who executed this operation to keep our neighborhoods safe.”
District Attorney Jeff Reisig praised the ongoing commitment of Yolo County law enforcement agencies that oversee and monitor registered offenders. “We successfully checked 100% of sex offenders with permanent addresses, and I’m pleased to report that 95% were in compliance,” Reisig said. “Operation Vigilance provides an added layer of deterrence for individuals who are required to register and may be at risk of re-offending.”
