High-speed chases, shooting after Boulder County marijuana robbery

BOULDER — One suspect remains at large in an armed marijuana robbery in Sunshine Canyon on Tuesday that eventually led to a suspected accomplice being fatally shot in a standoff with police after two separate high-speed chases.

The incident began around 9:30 a.m. Tuesday, when Boulder County deputies were called about an armed robbery in the 5200 block of Sunshine Canyon, in the foothills outside Boulder.

According to the Boulder County Sheriff’s Office, two men entered the victim’s home and demanded marijuana from the resident. When he didn’t comply, one suspect fired a shot into a sofa and then pistol-whipped the resident. The victim, a 45-year-old man, was transported to the hospital, where his injuries were not considered life-threatening.

The suspects then fled the area in a white 2012 Chevy Suburban with an undisclosed amount of marijuana and drove into Boulder. They were pursued by Boulder police and sheriff’s deputies before they abandoned the chase on Colo. 128 near Arvada.

The car, which had visible front-end damage, was spotted later in the day on Interlocken Loop headed toward Broomfield, then near Interstate 25 and Colo. 7, officials said.

According to the sheriff’s office, detectives executed a search warrant in Adams County and found the Suburban but not the suspects.

Boulder County Sheriff’s Cmdr. Heidi Prentup said she couldn’t say if investigators have recovered any of the marijuana.

Around 9 p.m. Tuesday, Longmont police tried to stop a different vehicle that they suspected contained one of the suspects, but the man refused to pull over.

A second chase ensued. After 30 minutes, the suspect’s vehicle struck another vehicle — officials haven’t confirmed whether or not it was a police car — and, radio traffic indicated, was soon driving with at least one flat tire.

Multiple agencies responded to the second chase, and by 9:45 p.m. a man was confirmed to have been shot and killed near the intersection of U.S. 85 and Bromley Lane in Brighton. No officers were injured.

It has not yet been revealed who shot the suspect, or how many officers fired. The Adams County Sheriff’s Office is the lead investigating agency on the case.

As for the Boulder County end of the case, District Attorney Stan Garnett said deputies from his office were on scene overnight Tuesday and are continuing to investigate the home invasion. He confirmed marijuana was involved and that there was a second suspect, but wouldn’t release any other details.

“There’s a lot we don’t know about what happened,” Garnett said. “We’re continuing to investigate whether there will be a Boulder County case involving anyone else.”

Garnett said Boulder County law enforcement members were on the scene of the shooting, and that his office also will remain looped in on the investigation in Adams County.

“We have some excellent detectives from many jurisdictions doing a complete investigation,” Garnett said.
