BOULDER, Colo. – The man involved in this morning’s officer-involved shooting has been identified and charged with multiple felonies in connection to several crimes in three jurisdictions.

Boulder Police detectives believe the suspect, identified as Trenton Joshua Dunham, 25, was involved in a series of incidents in Greeley late last night/early this morning to include breaking into a vehicle, stealing a firearm and a car, and shooting into a car and a house (No one was injured or killed). Dunham is then believed to have been involved in the armed carjacking and felony menacings that occurred near the intersection of U.S. 36 and Highway 121 in Broomfield around 6 a.m. today.

At approximately 6:06 a.m. today, Boulder Police received a call about a vehicle being driven on the Pearl Street pedestrian mall striking property near 15th and Pearl streets. Around the same time, Boulder Police received the information about the Broomfield incident.

The vehicle was not on Pearl Street when Boulder Police arrived, and officers began searching for it as did University of Colorado Police officers and Boulder County Sheriff’s Office deputies. Just before 7 a.m. officers spotted the vehicle and coordinated to deploy stop sticks to disable the vehicle. Though the sticks deflated the tires, the vehicle continued driving on its rims.

The driver continued down Table Mesa toward the U.S. 36 east ramp and then onto the sidewalk headed toward the RTD bus stop where community members were running away. During this time, the suspect also pointed a gun at law enforcement officers and officers fired their weapons at him.

Boulder Police officers then used vehicle maneuvers to stop the suspect’s vehicle and took the suspect into custody. Incredibly, there were no injuries to officers or community members during any of this incident in the city. The multijurisdictional Critical Incident Response Team will investigate the officer-involved shooting aspect of this investigation. This multi-agency team is designated to investigate use-of-force incidents in which any law enforcement officer used deadly, or potentially deadly, physical force against a person while acting under the color of official law enforcement duties.

In connection with these incidents, Dunham is being charged with:

  • Two felony counts of aggravated motor vehicle theft
  • One felony count of illegally discharging a firearm
  • One misdemeanor count of first-degree criminal trespass
  • One misdemeanor count of theft
  • One felony count of aggravated robbery
  • Three felony counts of menacing
  • One felony count of criminal second degree assault with a deadly weapon
  • Two felony counts of assault in the first degree
  • Two felony counts of criminal attempt first degree murder
  • One felony count of vehicular eluding
  • One felony count of possession of a weapon by a previous offender

Dunham did not suffer any serious injuries and is in custody at the Boulder County jail.

The Boulder Police Department is the lead investigating agency for the three-county crime spree and the Office of District Attorney Michael Dougherty (20th Judicial District) will be prosecuting all of the charges in this case.

Anyone who witnessed any part of these incidents or has any information about any of these crimes is asked to call Detective S. Cantu at 303-441-4328 reference case 22-4441.
