University Police Chief Carl Rowan confirmed the threat, and law enforcement conducted an extensive search of the building. The threat came just hours after the [University of Virginia announced bomb threats to its libraries](https://www.insidenova.com/headlines/george-masons-fenwick-library-closed-after-potential-bomb-threat-follows-similar-threat-at-uva/article_ae36f454-47bd-451c-b757-700e2d80a05f.html), and was part of a wave affecting [five Virginia colleges that Friday](https://www.vpm.org/npr-news/2026-03-13/uva-bc-gmu-odu-bomb-threats-public-safety-virginia-higher-ed), including Bridgewater College, Randolph-Macon College, and Longwood University. Because GMU was on spring break, campus occupancy was lower than usual. No devices were found, and the [all-clear was issued at 3:45 PM EDT](https://www.wusa9.com/article/news/police/potential-bomb-threat-reported-george-mason-university-library/65-d47bba74-1538-4533-b5ba-c72d8e2ec467).",
  "keyFindings": [
    "The emailed threat included a specific location and detonation time, requiring a higher-level response than generic bomb threats",
    "Five Virginia colleges were targeted on the same day, suggesting a coordinated campaign",
    "Spring break timing reduced the number of people affected but also meant fewer witnesses and lower campus staffing"
