A Halloween party in Denver ended in deadly gunfire on October 29, 2016, when an unknown person or persons opened fire at a house on 4335 N. Columbine Street. Twenty-seven-year-old Orlando Jackson, a Black man, was struck and taken to Denver Health Medical Center, where he later died; the medical examiner ruled his death a homicide. Another victim, 34-year-old Terrence Ashley, was also killed and a third person was critically wounded.

Denver police investigated the double homicide, but no arrests or suspect identifications were released. The case is listed as a cold case with the Colorado Bureau of Investigation and remains unsolved.

If anyone attended that gathering or has information about who entered the house that night, please contact the investigators handling the case.
