The rifles and ammunition in the Riverside case were found at a Corona home, not inside the SUV that police stopped. Riverside police say the Sept. 16 traffic stop involved an all-black Ford Explorer fitted with police-style lights and sirens; investigators said they believe it may have been used to impersonate police and carry out illegal activity in the Magnolia corridor, but the reports do not establish that it was.
What police say happened
The Riverside Police Department said officers stopped the Explorer at about 2 a.m. near Magnolia Avenue and McKinley Street over alleged vehicle-code violations. The driver, identified by NBC Los Angeles as 29-year-old Bryan Rodriguez Villareal of Corona, was on probation. Police also arrested his 30-year-old brother, Alejandro Padilla Villareal, who was on probation; investigators alleged he assisted with criminal activity tied to the case.
After the stop, officers searched Bryan Rodriguez Villareal’s Corona residence under probation search conditions, according to the reports. Police said they found five handguns, four rifles described as assault rifles, high-capacity magazines and more than 2,000 rounds of ammunition there. Both brothers were booked at the Robert Presley Detention Center on multiple charges and probation holds, the department said.
Similar reports, different allegations
Other California incidents illustrate why a vehicle resembling a patrol car is not, by itself, proof that someone impersonated an officer or used the vehicle to stop people. CBS Sacramento reported that CHP stopped a vehicle made to look like a Los Angeles County Sheriff’s patrol car near Yosemite Avenue in the Stockton area on July 6. The driver was arrested on suspicion of DUI and operating an unauthorized law-enforcement patrol vehicle; authorities did not say the driver had tried to pull anyone over.
In a separate Hemet case, the Hemet Police Department said an officer stopped a motorcyclist activating emergency lights on July 21, 2025, and reported that the rider wore clothing resembling local law-enforcement attire. The allegations and circumstances in Hemet differ from Riverside’s. These individual cases provide comparisons, not evidence that such incidents are becoming more frequent.
A further distinction appears in a June 24, 2025, Huntington Park case: the Los Angeles Times reported that police arrested a man suspected of posing as a federal immigration agent after encountering him in a Dodge Durango. That was a separate suspect and an alleged federal role; it offers no evidence about the Riverside investigation.
What remains unclear
The available accounts do not establish that the Explorer was used to impersonate police or commit crimes, identify the specific statutes police allege were violated, or detail the charges against either brother. They also do not establish whether any seized firearm or magazine violated California law. The California Department of Justice says assault-weapon restrictions depend on specified models or statutory characteristics, and generally defines large-capacity magazines as those able to accept more than 10 rounds; those definitions alone do not determine whether any item seized in this case was unlawful.
