Threat Keeps Majority Of St. Lucy’s Students Out

Administrators of St. Lucy’s Priory High School and the Glendora Police Department have been actively investigating a threat to the school. The concern has lead to 300 students out of roughly 538, over 55%, being held out of school on Monday by their parents.

School Administrators sent two emails out Sunday night to parents regarding a threat that they had recently received. The vague email to parents seemed to create more questions and uncertainty throughout the community as it was shared on social media platforms and neighborhood watch groups.

The following is a press release from the Glendora Police Department, detailing more of the threat’s origin and what it entailed:

St Lucy’s Priory High School Campus Threat

On Friday, January 5, 2018, staff from St. Lucy’s Priory High School reported a threatening letter they received in the mail. Since the time of this report and continuously over the weekend, Glendora Police Detectives have been investigating this incident, and have worked together with St. Lucy’s staff to coordinate a safety plan that was in effect this morning when classes resumed.

Out of an abundance of caution, Glendora Police Officers and Detectives, along with regular school security, were on campus today while students and faculty were present, without incident.

The theme of the threat tends to indicate it was authored by a student and was directed toward senior class students and faculty. The author expressed concern with strict school rules along with their stresses of high school academic life. The threat involved burning down the school campus and shooting unspecified people. The Glendora Police Department takes every threat to high school students and campuses seriously, and we are working closely with the staff of St Lucy’s High School to provide a safe school learning environment for all of the students.

Updates regarding this investigation will be periodically posted on the Glendora Police Department Facebook page,, and through our Twitter account, @glendora_pd. St. Lucy’s is open and classes are in full session at this time, and while every effort is being made to keep the campus safe and distraction free, the ultimate decision on whether or not to send students to school is up to the parents.

Anyone who has information about this incident, even if they wish to remain anonymous, can contact Glendora Police Detective Ryan Lombardi at 626-914-8286 or via email at
