Below are common questions readers ask, with clear, concise answers to help you understand the case, the legal tools used, and what this means for preventing teen radicalization.
Two teenagers, Caleb Vazquez and Cain Clark, attacked the Islamic Center of San Diego. They were found dead by suicide following the incident.

It underscores the role of families, schools, and law enforcement in coordinating safety plans and resources to prevent harm.
