(Northglenn, CO) - On May 28, 2026, at approximately 11:50 p.m., a Northglenn police officer attempted a traffic stop on a vehicle after observing erratic driving behavior in the area of Washington Street and East 112th Avenue.

The driver initially stopped but then fled the traffic stop. Moments later, the vehicle crashed into a home in the 10400 block of Clarkson Street. Officers located the driver, identified as 18-year-old Angelo Arias, at the crash scene and took him into custody.

During the investigation, officers determined a passenger was also inside the vehicle at the time of the crash. The passenger, an 18-year-old female, was transported to a local hospital with serious injuries sustained in the crash and later passed away.

As a result of the crash, a natural gas line was ruptured. A CodeRed emergency notification was sent to nearby residents, and several homes were evacuated as a precaution. Residents were allowed to return to their homes after utility crews shut off the damaged gas line, and the area was deemed safe.

Based on the investigation, including evidence of impairment, Arias has been charged with Vehicular Homicide, along with other related charges. Formal charges will be determined by the Adams County District Attorney’s Office. All persons are presumed innocent unless proven guilty in a court of law.

This remains an active investigation. Anyone with information related to this incident is encouraged to contact Detective Brummel at 303.450.8857 or [email protected].
