A Halloween party in Northglenn, Colorado, turned deadly when gunfire erupted shortly after midnight, resulting in three fatalities and three injuries. Police responded to reports of shots fired at a house party attended by around 25 guests and found one victim dead at the scene, while two others succumbed to their injuries later in the hospital. Authorities are actively searching for multiple suspects, indicating that the shooting was likely a shootout among partygoers, rather than a drive-by incident. The victims' identities have not been released pending family notifications. This incident is part of a larger trend, as the U.S. has experienced over 440 mass shootings this year alone. The Northglenn Police Department has stated that there are no known threats to the public at this time.
