A 16-year-old girl has been arrested in connection with recent threats made on social media against East Valley High School.

The suspect, who has not been named due to her age, allegedly posted the threats to a fake Snapchat account, according to a Spokane County Sheriff’s Office news release. She took a screenshot of the message and disseminated it among friends, some of whom continued to share it on social media Monday.

According to the sheriff’s office, the suspect made the threats because she “ ‘didn’t want to go to school.’ ”

The threats were quickly reported to authorities, and extra security measures were in place at the school Tuesday. Only 10 percent of East Valley High School students elected to attend school that day; by Wednesday, about three-quarters of students were in class.

Similar threats were made in recent days toward Mead and West Valley high schools; a juvenile suspect was arrested in connection with the Mead threat this week.

The 16-year-old has been booked into the Spokane County Juvenile Detention Facility on charges of harassment and threats to bomb and injure properties. Both crimes are felonies.

Investigations into the multiple threats are ongoing. The sheriff’s office asks that parents speak with their children about the importance of reporting threats to authorities, rather than simply disseminating them to their peers.
