Parents of students attending Lubbock ISD received a text message this morning indicating that the Monterey High School campus was "on hold due to weapon found on campus. Students and staff are safe. Please check email for more details."

An email from Monterey High School Principal Jack Perkeypile followed:

Good morning, Monterey Plainsmen family,
We are aware a gun was brought onto the campus today, and the weapon has been secured. Out of an abundance of caution, the hold protocol has been enacted while law enforcement ensures the campus is secure. Students and staff are safe and instruction is continuing normally. Please do not come to campus to pick up your student because this will delay the clearance process. An additional notification will be sent when the campus is clear. Having a weapon on campus is a direct violation of Lubbock ISD policy. There were no threats made; however, we have zero tolerance for any type of weapon on school grounds. Disciplinary action will be taken against the student(s) involved. We are committed to student safety and keeping you informed. Thank you for your continued support of our school.
Thankfully, the situation is under control and everyone is safe, but it's a frightening thought to have running through the minds of parents as they are working to wrap up the school year and all of the various extracurricular activities.

A secondary email was sent by Principal Perkeypile after administrators lifted the hold protocol,

hello Monterey,
This is jack Purkeypile, Earlier today, a gun was brought onto the campus, which is a direct violation of LISD policy.  I want to emphasize that there were no threats made; however, we have a zero tolerance for any type of weapon at school.  We enacted the hold protocol in an overabundance of caution to make sure the campus was secure, even though the weapon had already been confiscated and the perpetrators detained.  Disciplinary action was taken immediately.  We are committed to to student safety and keeping you informed.  We always emphasize to our students that if they see something, say something to a teacher, staffer, or principal, and in this case if truly payed off.  thank you for your support of your school.
