At 9:15 a.m. on Wednesday, the Colorado University – Boulder campus received a 911 call stating a student was seen on campus with a machete. The young man brandished the weapon during an altercation at the college campus’ Champions Center before entering the building.

As police rushed to the scene, students were alerted to the incident and asked to avoid the area via text message.

Police directed the man to drop the weapon. When he refused to do so, police shot and killed him.

“He [the suspect] was not following commands, and so at some point, we did have to neutralize him,” CU-Boulder Police Department official Scott Pribble said. “We don’t know anything yet other than the suspect is dead. Now we will turn it over to the Boulder County investigative team to continue the investigation.”

At 9:40 a.m., police announced the campus was safe again and business would continue as usual.

“On behalf of the entire campus, I want to thank the CU Police Department and Boulder Police Department for their quick action in resolving this situation and ensuring that no one was harmed here with the exception of the suspect,” CU-Boulder Spokesperson Ryan Huff said.

During the incident, CU-B Police took to Twitter to keep students in the loop on what was going on.
