The teens were planning to call in a bomb threat at Riverbend High School in Fredericksburg, which they attend, and then shoot at students and staff as they evacuated the building, said Capt. Jeff Pearce of the Spotsylvania County Sheriff's office. The students, ages 15 and 17, are being charged with conspiracy to commit murder and are being held without bond at a juvenile detention center, officials said.
The sheriff's office declined to name the teens, saying it doesn't identify juvenile suspects unless they are charged with a capital felony.
Pearce said authorities discovered the plot by conducting interviews, reviewing communication between the students and their social media accounts. The teens hadn't set a date for the attack, he added.
After searching the teens' homes, authorities said, they found more evidence that allowed them to charge the students with conspiracy to commit murder, Pearce said.
