DENVER — The California man accused of planting a bomb in a shopping center near the Nederland Police Department headquarters has been indicted on a federal charge of attempting to use a weapon of mass destruction, according to court documents.
The grand jury indictment, which was filed Tuesday, said 64-year-old David Ansberry, who also goes by the alias Jessie Howard, “without lawful authority, did knowingly use and attempt to use a weapon of mass destruction, namely, a destructive device.”

Ansberry faces a possible life sentence and a fine of up to $250,000 for attempting to set off the bomb on Oct. 11.
A Nederland police officer found a backpack outside the station and brought it inside, assuming it had been lost or abandoned.
An inspection of the bag revealed an explosive device and the shopping center at 20 Lakeview Drive was evacuated.
The device was determined to be a “legitimate explosive device” that was armed but failed to go off. The bomb squad detonated it early Oct. 12. No one was injured.
An affidavit said a cellphone was used as a detonator for the device, and investigators found another cellphone number “had dialed the detonator multiple times in an attempt to engage the bomb.”

Investigators were able to find out where the two cellphones were purchased based on the phone numbers assigned to them. They obtained a description of a person who purchased them in Denver and Longmont through surveillance video.
After seeing the video, police said a man matching the description was seen as the Boulder Creek Lodge was evacuated the morning of the bombing attempt.
The hotel provided a card that identified Ansberry who had rented a room. Ansberry was arrested as he was getting off a plane in Chicago on Oct. 15.
Investigators have not released any details on a possible motive.AlertMe
