Armed carjacking in Broomfield ends with officer involved shooting in Boulder

Boulder Police have identified the suspect in an early-morning Broomfield carjacking as Trenton Joshua Dunham, 25, who is being charged with multiple felonies tied to a string of crimes in three jurisdictions.

Dunham’s crime spree ended with a dramatic police-involved shooting just after 7 a.m. by the RTD eastbound station on Table Mesa Drive by U.S. 36. No one was injured during the melee and officers managed to disarm and arrest Dunham.

According to reports, Dunham was behind a number of crimes in the overnight and early morning hours in Greeley, including stealing a car and firearm, as well as shooting into another vehicle and residence. No injuries resulted from the incidents.

Following this, Dunham reportedly was involved in an armed carjacking in Broomfield around 6 a.m.

Broomfield Police Public Information Officer Rachel Haslett said the carjacking took place near the intersection of U.S. 36 and Highway 121.

Police reported two people were involved in the road-rage interaction that devolved into a carjacking when the drivers stopped at the intersection in question.

According to reports, when the drivers stopped one of the parties drew a gun and stole a bystander’s truck.

Boulder Police Public Information Officer Dionne Waugh said via email the stolen vehicle was eventually spotted nearly an hour after calls poured in about a vehicle being driven along Pearl Street Mall and striking property near 15th Street.

Police were initially alerted at 6:06 a.m. about a vehicle driving illegally on the pedestrian mall stretch of Pearl Street. The report coincided with details emerging from Broomfield Police regarding an armed carjacking.

When Boulder Police arrived at Pearl Street, Dunham had fled the scene and a search was initiated with assistance from the Boulder County Sheriff’s Office and University of Colorado Police.

Shortly before 7 a.m. officers spotted the vehicle and deployed stop sticks, which functioned to deflate tires but failed to stop the driver.

Motoring on rims, Dunham aimed down Table Mesa Drive toward the U.S. 36 east ramp, proceeding to plow onto the sidewalk and adjacent bus stop.

Police reported that commuters awaiting transit on RTD frantically scattered as Dunham came to a halt and exited the vehicle.

“Using vehicle maneuvers BPD officers were able to stop the vehicle & take the suspect into custody & recover the firearm,” Waugh reported via email.

Once the suspect was confronted he exited the vehicle and aimed a weapon at officers.

“The suspect pointed a gun at officers and officers fired their weapons at him,” she said. “Neither he, nor any officers, were struck or injured during this incident.”

Dunham, who was unharmed while being arrested, is currently in custody at Boulder County Jail and charged with 12 felonies and four misdemeanors, including: two felony counts of criminal attempt first-degree murder, two felony counts of aggravated motor-vehicle theft, one felony count of vehicular eluding, three felony counts of menacing, two felony counts of first-degree assault, one felony count of illegally discharging a firearm, one felony count of aggravated robbery, one felony count of criminal second-degree assault with a deadly weapon, one felony count of possession of a weapon by a previous offender, one misdemeanor count of first-degree criminal trespass and one misdemeanor count of theft.
