MSU Denver and CU Denver pushed alerts telling roughly 40,000 people across the three institutions to lock doors and to 'Run, hide or fight if appropriate.' The lockdown was [lifted just before 5 p.m. with one suspect in custody](https://denvergazette.com/news/stabbing-near-denvers-auraria-campus-prompts-lockdown-1-in-custody/article_f4717a5e-9728-11eb-941a-936f2bc5a6c7.html); the stabbing had occurred during a disturbance on a light rail train and posed no broader threat.",

  "context": "The Auraria Campus is one of the most unusual emergency-communication environments in higher education: a single downtown Denver campus shared by three institutions (Metropolitan State University of Denver, the University of Colorado Denver and the Community College of Denver) serving roughly 40,000 students. On April 6, 2021, [FOX31/KDVR](https://kdvr.com/news/auraria-campus-placed-on-lockdown/) reported that Denver Police were investigating a stabbing at the Auraria West light rail station on 5th Street near Walnut. MSU Denver and CU Denver sent students alerts that the campus was on lockdown and to 'Run, hide or fight if appropriate,' wording confirmed by [KKTV](https://www.kktv.com/2021/04/06/msu-denver-auraria-campus-placed-on-lockdown-tuesday-as-students-are-instructed-to-run-hide-or-fight-if-appropriate/). According to the [Denver Gazette](https://denvergazette.com/news/stabbing-near-denvers-auraria-campus-prompts-lockdown-1-in-custody/article_f4717a5e-9728-11eb-941a-936f2bc5a6c7.html), a man was hospitalized, a suspect was taken into custody, and the lockdown was lifted just before 5 p.m. with no known ongoing threat. The incident became a touchstone in a longer campus debate: students later told [FOX31](https://kdvr.com/news/local/auraria-students-calling-for-major-changes-to-campus-pd-after-run-hide-or-fight-alert/) the active-shooter-style language for a stabbing caused unnecessary panic, and the Student Advisory Committee to the Auraria Board folded the complaint into a resolution seeking changes to the emergency notification system.",
  "keyFindings": [
    "A shared campus serving three institutions means one off-campus stabbing triggered lockdown alerts from multiple universities' systems at once",
    "The verbatim 'Run, hide or fight if appropriate' wording (the standard active-shooter formula) was applied to a stabbing, which students said caused panic",
    "The lockdown lasted under an hour and was lifted just before 5 p.m. MDT once a suspect was in custody",
    "The episode fueled a student-led push to reform the Auraria emergency notification system and campus police communications"
