  "context": "Ardrey Auditorium is NAU's main performing-arts hall on Knoles Drive in Flagstaff, a venue that hosts commencement-season concerts and recitals. On the afternoon of May 14, 2026, [a phoned-in bomb threat](https://www.fox10phoenix.com/news/bomb-threat-reported-near-naus-ardrey-auditorium-building-evacuated) prompted NAU to push a NAU Safe alert shortly after 1 p.m. MST telling people to evacuate the area. NAU Police were joined by the [Flagstaff Police Department](https://www.knau.org/knau-and-arizona-news/2026-05-14/bomb-threat-prompts-evacuation-near-naus-ardrey-auditorium), who searched the auditorium and interviewed potential witnesses. A preliminary search around 2:30 p.m. found no imminent threat, and the [area was declared safe at 4:01 p.m. MST](https://azdailysun.com/news/local/education/nau-operations-return-to-normal-following-bomb-threat-at-ardrey-auditorium/article_e7ce7e1f-8a61-419d-8ba2-0df0234b9893.html). The incident fit a national pattern of phoned and emailed bomb threats targeting individual campus buildings during spring 2026, almost all of which proved unfounded after a sweep.",
  "keyFindings": [
    "NAU used a single-building 'evacuate the area' response rather than a campuswide shelter-in-place, reflecting a contained reaction to an unconfirmed threat",
    "The all-clear at 4:01 p.m. MST came roughly three hours after the initial alert, despite a preliminary search clearing the building by about 2:30 p.m.",
    "Arizona's lack of DST means the correct offset is MST (-07:00) year-round, not MDT",
    "The threat targeted a performing-arts venue during commencement season, when such buildings see heavy public traffic"
