UnfoundedNo evidence of an actual threat was found. The institutional response is documented because the alert communication is identical to what would occur during a real incident.

On the evening of Sunday, November 24, 2019, a single student screaming threats outside Gillson Hall on the University of San Francisco's main campus triggered widespread fear of an active shooter, with students locking themselves in buildings while university officials waited nearly an hour to issue any communication. The first official Dons Alert went out at approximately 7:50 PM PST stating only that there was no active shooter on campus. The student was arrested and was not armed.

Context

Background

Around 7 PM PST on Sunday, November 24, 2019, students at the University of San Francisco's Hilltop campus began posting videos of a male student screaming in a quad and trying to gain access to a locked building near Gillson Hall. The student had also reportedly made threats on social media. As panic spread on Twitter and group chats, students barricaded themselves inside buildings believing an active shooter was on campus. The San Francisco Police Department arrived and detained the student without incident; he was not armed. USF did not issue its first official Dons Alert until approximately 7:50 PM — a delay of roughly 50 minutes during which rumor outpaced official information. The university's terse message saying only there was 'no active shooter' drew sharp criticism from students who felt the school had failed to acknowledge what they had just experienced.
Analysis

Key Findings

The roughly 50-minute gap between students first reporting the disturbance and USF's first Dons Alert allowed Twitter rumors to dominate the information environment
The first official message stated what was NOT happening (no active shooter) without explaining what WAS happening, leaving students confused
The incident demonstrates how a single mentally distressed individual screaming and trying doors can replicate the information signature of an active shooter
Outcome
One student arrested. No weapon was recovered. The university faced significant student criticism for the slow pace of its emergency communication.
