ARVADA, Colo. — Four men and a juvenile have been charged after a chlorine bomb was discharged near an Arvada police officer causing him to pass out as he was attempting to clear debris from a roadway, according to a release from the First Judicial District.
Braiden Ulmer,19, Gavin Dawson, 19 Isaac Koch, 19, and Maxwell McCann, 19. All four of them posted bond and appeared in court on April 12. A juvenile male has also been charged.
All were charged with:
- Possession of a chemical, biological or radiological weapon.
- Conspiracy to commit possession of a chemical, biological or radiological weapon.
- Assault in the second degree.
- Criminal attempt to commit assault in the second degree.
Officers were dispatched to the area near West 72nd Avenue and Beech Street on April 7 for a traffic complaint.
According to the arrest affidavit, the officer who responded found street signs had been pulled out of the ground and laid down across the street in a pile, which created a barricade. He also found clear plastic wrap had been strung across the road around the signs.
While clearing the debris with the help of a civilian, the officer noticed a plastic bottle which had been thrown and landed in the roadway about 15 yards from him.
It began shrinking and released a “ton” of white-colored smoke, the release from the District Attorney's Office said. A short time later, the officer lost consciousness and suffered other symptoms from breathing the gas.
He was transported to the hospital and diagnosed chlorine gas exposure. The civilian also suffered minor symptoms but was treated at the scene.
