A man armed with a machete inside the Champions Center at the University of Colorado's Folsom Field was shot and killed Wednesday morning, the Boulder Camera reported, citing sources close to the investigation.
The Champions Center is the home of Colorado's football program and athletics administration.
In a statement Wednesday afternoon, Colorado athletic director Rick George said: "Regarding the incident this morning in our Champions Center, first and foremost all our student-athletes and staff are safe. We have safety protocols in place, and when everyone received the campus alert, all responded accordingly and the protocols were effective.
