ONU's [first emergency alert was issued around 2:16 PM EDT](https://x.com/ohionorthern/status/2051730239881912649), directing students, faculty, and staff to leave campus immediately. School officials organized buses near [McIntosh Center to transport people to Ada High School](https://spectrumnews1.com/oh/columbus/news/2026/05/05/ohio-northern-university-evacuates-following-bomb-threat), which served as the off-campus shelter. Law enforcement conducted a building-by-building search. By [5:41 PM EDT, ONU issued an all-clear](https://www.adaicon.com/news/202605/ohio-northern-issues-all-clear-following-bomb-threat-alert), saying all buildings had been searched and cleared. Residence halls reopened that evening; academic buildings, including [Heterick Library](https://wowo.com/bomb-threat-forces-evacuation-at-ohio-northern-university-all-clear-issued/) and the James Lehr Kennedy Engineering building, remained closed until 7 AM Wednesday. The incident was part of a broader pattern of phoned and emailed bomb threats targeting US universities during the 2025–2026 academic year.",
  "keyFindings": [
    "ONU's small footprint (about 2,900 students) made a full campus evacuation operationally feasible, a response option unavailable to larger universities",
    "The 'refrain from using your phone' instruction reflects bomb-squad protocol but is rarely seen in larger university alerts, suggesting tight coordination with Ada Police",
    "Total elapsed time from initial alert to all-clear was approximately 3 hours 25 minutes, on the longer end for campus bomb threats but reasonable given the entire campus had to be searched"
