SOUTH PASADENA, Ca. (WHSV)-- Now, these teens are facing charges in juvenile court in the weeks to come.
Police say a 16 and 17-year-old had researched guns and explosives on the internet. Investigators found their plans to kill on social media.
The teens told investigators they were prepared to die in a shootout following a massacre. Through the power of social media, the killing was prevented.
"We may have saved some lives today, in my opinion. I think we really saved lives," said Art Miller, the chief of police in South Pasadena.
Police say the two boys planned on killing three people who work in the school and as many students as possible.
The teens' school starts on Aug. 21.
