Story summary

Two 15-year-old girls, one from Corona High School and another from Norco High School in California's Riverside County, were arrested for allegedly planning a school shooting. The FBI first alerted local authorities on October 6 after discovering threatening social media communications. Police executed search warrants, examined electronic devices, and searched several residences before identifying the second suspect on October 20.

The girls are accused of spending months researching past school shootings and discussing methods to obtain weapons for their alleged attack at Corona High School, though they did not succeed in acquiring any firearms or other weapons. Both remain in custody charged with conspiracy to commit murder; if convicted as adults, they could face a sentence of 25 years to life.

Police stressed that while the planning was extensive, no specific date for an assault had been set and authorities intervened before any attack materialized. FBI Director Kash Patel emphasized the seriousness of threats against schools, stating, "There is no greater priority than protecting our kids."
