A Poway student sent a threatening email over the weekend to a Twin Peaks Middle School administrator stating he planned to shoot a teacher and 23 fellow students at the school on Monday morning.
Detectives from the San Diego County Sheriff's Department investigated the alleged shooting threat Saturday and found numerous rifles and handguns in the 12-year-old student's home.
According to officials, the email threat -- which was sent to a school administrator Friday night -- made reference to 3,000 rounds of ammunition as well as numerous firearms in the planned shooting at the Poway middle school.
NBC 7 spoke exclusively with the teacher referenced in the email. She wishes to remain anonymous to protect her safety.
"I kept asking myself, `Why me?' Literally wracking my brain trying to figure out who it is," she said.
Detectives worked with the Poway Unified School District and San Diego's Computer and Technology Crime High-Tech Response Team to identify the source of the email. CATCH is a taskforce of federal, state and local agencies that investigate technology related crimes.
After identifying this particular Twin Peaks Middle School student as the source of the email, detectives served a search warrant at the boy's house and confiscated numerous rifles and handguns, as well as several computers.
On Saturday at around 5:30 p.m., the 7th grade student was taken into custody and admitted to a local hospital for treatment and evaluation.
Detectives believe the boy planned to act alone and say there is no evidence to suggest anyone else was involved in making the threats.
The school and law officials are on high-alert.
"This could really happen anytime, anywhere," the Poway teacher threatened in the email told NBC 7.
