A 19-year-old University of Colorado Boulder student was killed and another student critically injured in a shooting at a Halloween house party in Boulder, Colorado, late on Saturday, October 31, 2026. The tragedy has left students, families and the wider university community grieving a young life lost and hoping for the recovery of the injured student.
The shooting happened shortly before 11:30 p.m. at a home in the 700 block of Marine Street, in the University Hill neighbourhood, near the CU Boulder campus. Earlier that evening, police had responded to a noise complaint and shut down the gathering. Although most guests had left, a smaller group reportedly remained inside.
Investigators believe a group later attempted to force its way into the house before gunfire erupted. Both victims, 19-year-old male students, were taken to hospital. One died after arriving, while the other remained in critical condition. Their identities had not been publicly released in the available reports.
The incident has deeply unsettled the campus community, with students and residents expressing shock and sadness. For those who knew the victims, the sudden violence has brought grief and difficult questions. The university community is left to support one another as families face the painful consequences of the tragedy.
Boulder police are continuing their investigation, interviewing witnesses and seeking information from people who may have seen what happened. As the community awaits further details, thoughts remain with the deceased student’s loved ones, the injured student’s family and everyone affected by the shooting.
