Confirmed HoaxDetermined to be a hoax. The institutional response is documented because it reveals how the alert system performed under a perceived real threat.

Northwest College in Powell, Wyoming was evacuated and closed on September 22, 2016 after the Wyoming Office of Homeland Security received an anonymous email threatening pipe bombs at government buildings and schools statewide. Community college presidents across Wyoming closed their campuses as a precaution; NWC activated its emergency notification system at 12:24 PM MT. Law enforcement determined the threat was not credible; the campus reopened the following morning.

Context

Background

Northwest College is a community college in Powell, Wyoming, in the Big Horn Basin region. On September 22, 2016, the Wyoming Office of Homeland Security received an anonymous email threat around 9:30 AM MT through the state's enterprise technology system. The email, signed 'Archangel Michael' with the subject line 'WYOMING IS BEING TURNED TO DUST,' claimed that 50 thermite pipe bombs had been placed across official buildings in Cheyenne, 600 bombs hidden in multiple Wyoming cities and government buildings, 50 explosive sets at the Cheyenne Regional Airport, and 500 pounds of explosives in 40 Wyoming schools. NWC's Command Team activated the emergency notification system at 12:23-12:24 PM MT, announcing the campus closure and directing employees to leave and resident students to go to their halls. Community college presidents at Western Wyoming, Eastern Wyoming, and Northwest College all closed their campuses, while other Wyoming colleges remained open after assessing local threat levels. Law enforcement swept buildings including the DeWitt Student Center. The threat was later determined not credible and similar threatening emails had been sent to multiple states. Normal operations resumed the following day.
Analysis

Key Findings

A single mass-emailed hoax threat forced the simultaneous closure of multiple Wyoming community colleges within hours
NWC's emergency notification activated at 12:24 PM MT, approximately three hours after the threat was received by the state
The multi-campus response demonstrates how a non-credible statewide threat can disrupt rural college communities far removed from the purported targets
Residence hall students were briefly locked in before the restriction was lifted, reflecting a layered emergency response
Outcome
Threat was determined non-credible by law enforcement. No explosive devices were found. Campus reopened Friday morning after the all-clear was given.
