San Marcos High School, located in San Diego County, found itself under a lockdown early today morning, following a bomb threat. The local Deputies, alongside K-9 units from Cal State San Marcos and ATF, were quickly deployed to conduct a thorough search of the school premises. As FOX 5 San Diego reported, parents were advised to not approach the school during the lockdown.
Throughout the incident, San Marcos Unified School District (SMUSD) kept parents and staff updated through periodic messages, informing them about the lockdown status and subsequent police investigations. The lockdown, which lasted until about 11 a.m., was lifted when the Deputies gave the all-clear signal. This was confirmed by ABC 10News.
During the lockdown, students and staff already present on campus remained confined, while newcomers were promptly redirected. The San Diego County Sheriff's Department verified that the bomb threat was received through one phone call around 8:06 a.m, to swiftly enter and secure the school premises, one teacher narrated her experience to FOX 5 San Diego.
Post lockdown, deputies continued to maintain high vigilance through additional patrols for the rest of the day. Parents were allowed to pick up their children only after the all-clear signal was issued. Fortunately, the threat was deemed non-credible and no other schools were mentioned in the threat call.
