A former Riverside County sheriff's deputy who patrolled out of the Colorado River Station in Blythe has permanently lost his ability to work in California law enforcement after admitting he illegally rummaged through confidential government databases. Matthew Enrique Estrada, 53, pleaded guilty to two misdemeanor counts of unlawfully accessing privileged information via government computers, closing out a case that began with a tip to internal investigators more than a year ago.
Estrada entered his plea in Indio, where Riverside County Superior Court Judge John Ryan certified the terms of a pretrial agreement and imposed a stipulated sentence, according to KESQ. The outlet reports the sentence included a requirement that Estrada relinquish his Peace Officer Standards and Training certification, a step that makes him ineligible to work as a law enforcement officer anywhere in California. What began as two felony counts was reduced to misdemeanors under the pretrial agreement reached with the Riverside County District Attorney's Office.
A Yearlong Trail From Tip to Charges
The case traces back to June 24, 2025, when sheriff's detectives learned that Estrada had accessed confidential data on several occasions without authorization or justification, per the same KESQ account. The sheriff's Special Investigations Bureau spent months building the case before gathering enough evidence to request charges from prosecutors, who ultimately filed a criminal complaint on May 29, 2026. Estrada had been a deputy since June 2007 and was most recently assigned to the Colorado River Station in Blythe, the station's report notes.
Court proceedings moved relatively quickly once charges were filed. NBC Palm Springs reported that Estrada was arrested in May following the nearly yearlong internal probe, before being arraigned the following month. The Larson Justice Center in Indio, where Ryan handed down the stipulated sentence, became the final stop in a process that started with a confidential tip inside the department.
Not an Isolated Case in Riverside County
Estrada's plea lands amid a string of similar allegations against Riverside County deputies. As of October 2025, he became at least the third Riverside County sheriff's deputy accused that year of illegally accessing a computer database, according to the Press-Enterprise. That report detailed the October 2025 arrest of Deputy Dakota Lasher Robson on suspicion of unauthorized computer access along with vehicle theft and possession of a stolen vehicle, and the earlier arrest of Deputy Michael Gene Schmidt, who was accused of accessing confidential database information for personal use and later pleaded not guilty to four counts of unauthorized computer-database use.
A separate allegation covered in the same Press-Enterprise report involved former Deputy Eric Piscatella, who was accused in a lawsuit of using his patrol-car computer to search for a woman's address and cellphone number to pursue her romantically. In response to the pattern, the Riverside County Sheriff's Office said it would continue conducting audits of law enforcement databases used by its employees and investigate noncompliance for possible criminal culpability.
A Statewide Pattern of Database Misuse
The issue extends well beyond Riverside County. Data from the California attorney general's office showed 1,002 confirmed cases of computer-database misuse by California law enforcement employees over a 10-year period, as reported by the Sacramento Bee. Over that same decade, 82 employees resigned, 86 were fired and 125 were suspended following misuse investigations, though criminal prosecution proved rare, with only 40 misdemeanor and 14 felony cases filed statewide.
Other cases cited in the Bee's reporting illustrate how varied the misuse can be. Former San Francisco police Sgt. John Haggett pleaded guilty to a misdemeanor for misusing DMV computer information and was ordered to pay $150 in restitution, while a San Jose police officer was charged with accessing police computers to allegedly write false traffic and parking tickets against two people involved in a lawsuit with the officer. A California Highway Patrol officer was separately accused of digging through computer files for information on a romantic rival.
For Estrada, the consequences are now final: probation and a permanent end to any law enforcement career in the state. His case adds another entry to a growing list of Riverside County deputies whose access to sensitive government systems became the subject of criminal scrutiny rather than routine duty.
