Corona Police Lt. Robert Montanez said the alleged target was the school campus. He also said there were indications that revenge may have played a role, without establishing a definitive motive.

One attends Corona High School and the other attends Norco High School. Police have described their arrests as involving conspiracy to commit murder. The allegations concern a possible future attack, rather than a shooting that occurred at the campus; the public accounts reviewed do not report a completed attack.

A joint investigation led to the Corona High student's arrest. Detectives subsequently obtained search warrants for electronic devices and communications and searched several Riverside County residences. Police said that work identified the Norco High student, who was also arrested. [1](https://www.coronaca.gov/news/investigation-leads-to-two-arrests-in-school-threat-case) According to police, the students had spent several months researching school shootings and discussing how they might carry out an attack at Corona High. Investigators also said the pair discussed obtaining weapons. Police said no weapons were found during the searches and that the students had not acquired them. The alleged attack was discussed for an unspecified future date, rather than a publicly identified day.

[3](https://www.cbsnews.com/losangeles/news/teenage-girls-arrested-corona-high-school-shooting-plans-fbi-investigation/) The police release said the Riverside County District Attorney's Office was reviewing the case. It did not announce a prosecutorial decision or provide a court schedule. It also did not specify the second student's arrest date. The release describes investigators' conclusions but does not reproduce the underlying messages or search-warrant evidence. Those limitations leave important details unverified independently; the police allegations are not findings of guilt. [1](https://www.coronaca.gov/news/investigation-leads-to-two-arrests-in-school-threat-case) ABC7 reported that the investigation remained ongoing, and its October 22 account did not announce a court outcome or a final decision by prosecutors. Montanez's comments added an allegation about a list and a possible motive, but did not establish who appeared on the list or an attack date. The report does not provide the list itself for independent examination or describe a response from the teenagers.

The department urged students and parents to report concerning information promptly and directed tips about the investigation to Detective Edwards at 951-279-3656.
