Four Hours of Vague Alerts: UD's Bomb Threat Response Prompts Presidential Promise to Fix Emergency Communication

DEbomb threatemergency notificationmedium confidence
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 September 30, 2024, the University of Delaware evacuated Gore Hall, Mitchell Hall, and Sharp Laboratory after receiving a report of a possible explosive device. Vague UD Alert messages left students uninformed about the nature of the threat for nearly four hours, prompting Interim President Laura Carlson to promise improvements to emergency communication protocols.

Context

Background

On the morning of September 30, 2024, the University of Delaware Police Department received a report of a possible explosive device on campus just before 11:00 AM. The first UD Alert was sent at 11:19 AM referencing 'police activity' near Gore Hall, followed by an evacuation order for Gore Hall, Mitchell Hall, and Sharp Laboratory at 11:44 AM. Newark Police closed South College Avenue between Delaware Avenue and Park Place as police and bomb-detection resources swept the buildings. The investigation determined the report was unfounded. During its investigation, UD Police learned that multiple institutions regionally and nationally received similar reports of potential safety threats on the same day. The all-clear was issued at approximately 1:53 PM EDT. Interim President Laura Carlson subsequently promised to re-evaluate how UD communicates during emergencies, acknowledging that vague alert messaging had left students, employees, and the public uninformed about the nature of the threat for nearly four hours.
