## Summary

Omar Perez, 18, has been charged with murder and related offences over the fatal shooting of University of Colorado Boulder student Luca Hanlon at an off-campus Halloween party. Police say they have identified everyone shown in footage released after the shooting, while prosecutors consider whether others should face charges.

An affidavit says officers first attended the gathering after a noise complaint, and returned about 90 minutes later following reports of gunfire. Perez allegedly returned with a group, became involved in a confrontation and, wearing a SWAT-style outfit and “Purge” mask, shot Hanlon in the neck and another student in the leg; Hanlon died the next day. Perez’s sister recognised his clothes in police images and contacted investigators, and location data from a family tracking app helped trace his movements. He is being held without bond, with a preliminary hearing scheduled for 10 February 2027.
