A midday bomb threat at Windsor High School today sent the campus into lockdown and shut down a stretch of Windsor Road, turning an ordinary school day into a tense law-enforcement operation.
Students and staff were ordered to shelter in place while multiple agencies converged on the campus. Families were told to steer clear of the area as deputies worked to figure out whether the threat was real or a cruel hoax.
The Sonoma County Sheriff's Office put out an alert that read, "We are currently investigating a bomb threat to Windsor High School. The school is on lockdown and there are multiple law enforcement agencies assisting," according to Patch. Sent at about 12:31 PM, the advisory told parents not to come to campus and promised more instructions as they became available.
Officers Seal Off Windsor Road
Authorities shut down the 8000 block of Windsor Road starting around 12:15 PM while deputies and partner agencies carried out sweeps, KRON4 reported. Law-enforcement vehicles formed a visible perimeter around the school as officers moved through their safety checks and worked to secure students inside.
Past Threats and School Protocols
This is not the first time local schools have had to move fast in response to a threat. In April 2025, The Press Democrat reported that a Windsor High student was arrested after posting a threatening message on Snapchat.
Windsor Unified School District notes on its website that it uses ParentSquare and other official channels to reach families during emergencies or campus incidents, which is how parents are expected to receive updates, according to Windsor High School.
What Parents Should Do
Investigators asked the public to avoid the area and said anyone with information about the bomb threat should contact the Sonoma County Sheriff's Office, KRON4 reported. Parents were urged to stay put and wait for official messages from the school or district rather than driving to campus while the response remains active.
