CHP Traffic Stop Leads to Seizure of 50,000 Fentanyl Pills

On August 7, 2025, at approximately 6:50 p.m., a California Highway Patrol (CHP) officer observed a white Nissan Altima with no license plates traveling southbound on Interstate 5, just north of Walnut Grove Road. The vehicle was following another car too closely—about two car lengths—and was traveling at 79 mph in a 70 mph zone. CHP officers conducted a traffic stop and contacted the driver, identified as Christopher Perez. Perez stated he had traveled from Los Angeles to sell his vehicle in the area and planned to return home via rideshare.

In the trunk, officers located five plastic bags containing blue M30 pills. The pills—approximately 50,000 in total—were determined to be counterfeit oxycodone containing fentanyl.

Perez was arrested and booked into the San Joaquin County Jail. He is currently charged with:

• HS 11370.4(c)(1)(E) – Possession of fentanyl for sale in excess of four kilograms in weight

The San Joaquin County District Attorney’s Office remains committed to prosecuting those who traffic dangerous narcotics and to supporting efforts that keep our communities safe.
