A man, later identified as David Michael Ansberry, was taken into custody over the weekend in connection with the Oct. 11 incident, two law enforcement officials with knowledge of the investigation told The Associated Press. The officials spoke on condition of anonymity because they were not authorized to speak publicly about the case. Ansberry, 64, is in custody outside state lines.

A detective found the device in a backpack and brought it into the police station, believing it was lost property. Robots searched the device and it was eventually detonated in the parking lot of the town’s main retail complex, a strip mall that houses the five-officer police department.

Investigators say it was an active explosive that failed to detonate.

It was not immediately clear what charges Ansberry would face. U.S. attorney spokesman Jeff Dorschner declined to comment on whether anyone else was involved in the incident.

The case rattled the mountain-ringed town of 1,500 people southwest of Boulder best known for its love of legal marijuana and its annual celebration of a frozen corpse that draws tens of thousands of revelers.
