Colorado murder suspect in ‘Purge’ mask identified — after student killed on Halloween

Boulder police have identified everyone shown in footage released after a Halloween party shooting that killed University of Colorado Boulder student Luca Hanlon, 19. The primary suspect, Omar Perez, 18, has been charged with murder and related offences; investigators are continuing their inquiry and prosecutors may bring further charges.

Police say officers first attended the off-campus gathering after a noise complaint, and returned about 90 minutes later following reports of gunfire. An affidavit alleges Perez returned with a group, became involved in a scuffle and shot Hanlon and another 19-year-old student, who was wounded in the leg. Perez is being held without bond, and his preliminary hearing is set for 10 February 2027; the other people identified have not been reported charged.
