The riot on March 6 started as a party near 10th Street and Pennsylvania Avenue. The gathering started small and grew into the hundreds as the day went on, which violated COVID-19 restrictions on gatherings.

The party then turned destructive and violent when officers attempted to disperse the crowd. Police officers were struck with bricks and rocks and first responders’ vehicles were heavily damaged. Numerous community member vehicles were also damaged, including one that was flipped over by a mob and another that was struck with objects as it attempted to drive south on 10th Street. Many Street signs in the area were damaged.

Investigators from the Boulder Police Department, University of Colorado Police Department and the Boulder County District Attorney’s Officer spent hundreds of hours reviewing over 1,000 video submissions and tips. 

“We knew early on that due to the massive amounts of evidence this would be a long investigation and then the mass shooting at King Soopers caused further delays,” said Chief Maris Herold. “We made a promise to our community that there would be arrests and even though it has been a long road we kept that promise.”

In total ten arrests were made, and an additional three warrants are still outstanding. The CU Boulder Office of Student Conduct and Conflict Resolution received approximately 200 referrals for possible violations under the university’s student code of conduct.
