Police in Walnut Creek say a local teenager turned the state’s sex offender registry into his own target list this spring, roaming the city with a BB-style gun and confronting people he believed were registered offenders.
The boy, whose name is withheld under juvenile privacy laws, was arrested in March after what investigators describe as weeks of self-styled vigilantism. Officers say he had a handwritten list of names from the public registry and, on several occasions, fired his BB-style weapon at people he believed were listed there. The case remains under investigation in juvenile court, and authorities say his identity will not be released.
According to The Mercury News, the teen was taken into custody on March 15 on suspicion of brandishing a weapon and assault with a firearm after a series of confrontations around Walnut Creek. Officers recovered a BB-style pellet gun and the handwritten list during the arrest, the outlet reports. Court and police records reviewed by the paper say the youth accosted and threatened individuals whose names appeared on the public registry.
The state’s sex offender registry is billed as a community safety tool, not a license for street justice. The California Department of Justice explicitly warns that Megan’s Law data cannot legally be used to harass, threaten, or harm registrants and that misuse can trigger criminal or civil penalties. Law enforcement officials stress that looking up a name is one thing, and taking action on it is something the law treats very differently.
Drug Probe and a Student Hospitalized
The BB-gun investigation soon overlapped with a separate case. Detectives later searched the teen’s home on Creekside Drive in connection with an alleged marijuana sales operation targeting high school students. Officers say they seized a box of cannabis edibles and about $1,300 in cash during that search.
Investigators also found Instagram messages in which the suspect allegedly offered marijuana and psychedelic mushrooms and discussed bulk discounts, according to The Mercury News. That warrant was tied to an April incident in which a Las Lomas High School student accidentally ate a cannabis-infused sandwich and ended up hospitalized, the paper reported.
Edible Risks and Public Health Warnings
Health officials say that kind of scare is becoming more common. A recent review by the Centers for Disease Control and Prevention found sharp increases in emergency room visits involving cannabis edibles among children and teenagers. The Food and Drug Administration has repeatedly warned that THC-laced snacks can look nearly identical to ordinary cookies, candies, and chips, and urges adults to store them securely and out of reach.
Officials recommend contacting poison control or emergency services right away if someone, especially a child or teen, shows sudden signs of THC intoxication such as confusion, extreme drowsiness, or trouble breathing.
How the Law Treats BB Guns and Vigilantism
California does not treat “fake” guns as toys when they are used to scare people. Under the California Penal Code, it is a misdemeanor crime to draw or display an imitation firearm in a threatening way if it causes someone to reasonably fear bodily harm. Prosecutors can also pursue more serious assault charges involving weapons under a separate section of the California Penal Code, which can carry significantly stiffer penalties.
Even if a BB-style pellet gun does not qualify as a firearm under federal standards, courts have allowed serious charges when victims say they believed they were facing a real gun and reacted in fear.
Why Officers Worry About Copycat Violence
Local police say they are especially sensitive to cases that mix vigilantism and the sex offender registry. They point to a high-profile Fremont homicide last year as a worst-case scenario. In that 2025 case, investigators say suspect Varun Suresh used the public registry to pick his target and is now charged with murder. A Fremont Police Department news release states that detectives found evidence Suresh deliberately sought out a registered offender before the killing.
Walnut Creek police say their own investigation into the teen’s actions is ongoing and are asking anyone with information to call the department’s tip line. Because the suspect is a minor, his court records remain sealed while the case moves through the juvenile system. Police and school officials say they are also working on outreach to parents and students about safety, the dangers of illicit edibles, and the limits of taking justice into one’s own hands.
