Boulder County, Colo. - Following a jury trial, Duy Nguyen has been found guilty of all charges, including Criminal Attempt to Commit Murder in the First Degree (F2), Assault in the First Degree (F3) and two crimes of violence as sentencing enhancers.

Just after 8:45 pm, on February 5, 2025, Chance Cardona drove home from the Colorado Mountain Kava Bar in Longmont, Colorado. As soon as he parked in his apartment complex and opened the door, he was shot point blank at least six times. He had gunshot wounds to his face, shoulder, arm, and thigh. Mr. Cardona was able to call 911 and ultimately survived his injuries.

Based on Mr. Cardona’s partial identification to officers on scene, automatic license plate reader images that caught the defendant’s vehicle fleeing the scene of the crime, and shell casings collected from the scene, the Longmont Police Department was able to determine the identity of the defendant. After executing a search warrant on her house, law enforcement found the gun used in the shooting and collected the defendant’s electronic devices, which revealed that the defendant had been planning the shooting for weeks. The defendant and the victim had known each other from a prior relationship that had ended months before the offense.

The sentencing range for Criminal Attempt to Commit Murder in the First Degree is 16 to 48 years in the Department of Correction and on the First Degree Assault, the range is 10 to 32 years in the Department of Corrections.

Sentencing is set for February 13, 2026, at 10:00 a.m.

District Attorney Michael Dougherty stated, “I am grateful to the Longmont Police Department for their excellent, thorough response to this shooting. Their hard work and the evidence from their investigation, including from the automatic license plate reader, is why this terrible shooting was solved. Our DA team has fought hard to secure justice for this victim; I appreciate the nights and weekends our team poured into it. Now, thanks to the service of the jurors, the defendant can be held fully responsible for this inexcusable act of gun violence.”

Longmont Police Chief David Moore stated, “This case is a tragic one, as the victim was ambushed and suffered multiple gunshot wounds. Thanks to the dedication and tireless efforts of our officers, detectives, staff, and the Boulder County District Attorney’s Office, justice has been served, enabling the victim to begin the healing process. This outcome reflects a remarkable team effort, and I greatly value the strong partnerships we have with our fellow agencies.”

The District Attorney’s Office will have additional statements after the sentence is imposed.
