I apologize for this late call. This evening, Andalucia Middle School received another threat for a possible school shooting tomorrow, Thursday, March 8. The Phoenix Police Department is involved and another person has been arrested. Tomorrow, we have requested additional presence of police on campus. If you choose to keep your children home for the day, their absence will be excused. In addition, all backpacks will be searched upon arrival at school. Students may wish to leave their backpacks at home. When students arrive to school, our staff will be present to escort students directly into classrooms, and the school will remain on lockdown as we continue to assess the situation throughout the day. If your child normally walks to school, you might want to provide additional supervision to and from school tomorrow.
As additional information becomes available, we will keep you updated. Tomorrow, we ask for your continued patience. In order to keep phone lines open, please do not call the school for information. Updated information will be posted to the district’s website at www.alhambraesd.org as well as Andalucia’s website.
