Updated 3:30 p.m. -- A man armed with a machete was shot and killed by police on the Boulder campus of the University of Colorado Wednesday morning after he refused orders to drop his weapon.
The incident happened at a sports medicine building on the Boulder campus. University officials initially said the armed man had been taken into custody. Students were alerted to the shooting by text message and warned to take "protective action."
The man's motive's were not immediately clear, but the Boulder Camera reported:
A source close to the investigation told the Daily Camera that the suspect was a white male who appeared to be a "religious zealot of some kind" and who had been overheard talking about "looking for sinners" and referencing the commandments.
Classes are continuing on as normal, though university officials are warning students to avoid the area near the Champions Center due to the ongoing investigation.
Later in the day there were reports of an active shooter at the school's student center, but campus police told The Associated Press those reports were false.
