Overview
- Both unnamed 15-year-old female students — one from Corona High and one from Norco High — remain in custody on charges of conspiracy to commit murder while the Riverside County district attorney reviews the evidence.
- The investigation began after the FBI alerted the Corona Police Department on October 6 about social-media communications that raised concern, triggering a joint probe and immediate arrest of a Corona High student.
- Police say warranted searches of phones, devices and multiple residences uncovered months of online research into past school shootings and discussions about how to carry out an attack.
- Authorities report no weapons were found and that the suspects discussed methods to obtain weapons but had not succeeded, and they are urging anyone with information to contact Corona police.
- Officials call the case an example of how social-media monitoring and interagency work can disrupt threats before violence, and the arrests will move through juvenile procedures with names withheld because the suspects are minors.
