Context

Background

Colorado State University Pueblo is a regional public master's university in Pueblo, Colorado, serving approximately 4,000 students. On June 28, 2022, an unidentified male caller phoned the Pueblo Police Department claiming a bomb was in a classroom in the Hasan School of Business with only one hour remaining. The call was routed to the Pueblo County Sheriff's Department, which handles campus security. The building was evacuated with limited staff inside as no classes were in session during summer. The Pueblo Metro Bomb Unit swept the building and cleared it by just after 1:00 PM MT, finding no suspicious devices. The threat was determined to be a hoax. The limited occupancy during summer made evacuation straightforward, but the case illustrates the ongoing vulnerability of academic buildings even during off-peak periods.
