Overview
- Two teenagers accused of the Islamic Center of San Diego attack last Monday shot and killed three people before dying in an apparent murder‑suicide, police and court records say.
- Documents show Caleb Vazquez alarmed classmates and staff over more than a year with actions such as dressing as notorious killers, praising mass shooters, researching the dark web and making threats.
- School officials and friends alerted police in January 2025, triggering a welfare check that led to a 72‑hour psychiatric hold and a temporary gun‑violence restraining order.
- Police filings say officers could not interview Vazquez alone and that his father refused to let them verify that home firearms were secured; the family said it moved weapons to storage and a judge later dismissed the restraining order.
- Federal and local investigators are treating the case as an active probe that includes a hate‑crime investigation, and the records have intensified questions about limits of short‑term holds, restraining orders and online radicalization.
