(10NEWS) — POWAY, Calif. – Crisis counselors and extra staff were expected to be at Twin Peaks Middle School Monday to help students cope with their feelings about a 12-year-old boy’s threat to open fire on the Poway campus, specifically to kill 23 students and a teacher.

The boy was taken into custody and then to a hospital for treatment and evaluation on Saturday, according to the San Diego County Sheriff’s Department.

On Friday night, the boy sent an email to a Twin Peaks administrator, saying a teacher, whose name was withheld, and 23 students would be shot, sheriff’s officials said. He also allegedly made reference to 3,000 rounds of ammunition and numerous firearms.
