A Bismarck man who once built a pipe bomb that blew off another man's arm now faces a federal indictment related to building pipe bombs during the summer.

Doug Feist, 31, is slated to stand trial Feb. 19 on a federal indictment charging him with possession of ammunition by a convicted felon, conspiracy to manufacture and possess a destructive device, unlawful making of a firearm (destructive device), and unlawful possession of unregistered firearm (destructive device).

Feist also is slated to stand trial Feb. 19 on a charge in Burleigh County of possession of explosives, which stems from an incident involving a sparkler bomb in July. Burleigh County Assistant State's Attorney Julie Lawyer, who is prosecuting the Burleigh County case, said she was unaware the two trials were set for the same day.

According to an indictment filed in federal court on Dec. 6, Feist is accused of making several pipe bombs over the summer with the help of a "co-conspirator,"who was not named in the indictment.

Court documents say Feist, a convicted felon, purchased approximately 50 rounds of shotgun ammunition on June 24. He and the co-conspirator allegedly removed shot-shell powder from the shells, then used the powder, fertilizer and PVC pipe to make a pipe bomb. They later attempted to detonate the bomb, documents said.

Feist also is accused of using explosive material from commercial fireworks to build a pipe bomb, which documents say was used to blow up a pump house in Kidder County.

Feist pleaded not guilty to all four charges on Dec. 14. U.S. Magistrate Judge Charles S. Miller ordered Feist held in federal custody, deeming him a flight risk and danger to the community.

Miller wrote in a detention order that prosecutors have a strong case against Feist, including witness testimony and videotape of him buying ammunition. The order said Feist's criminal history and habit of not following court orders also were factors in holding him until trial.

"The court takes particular note of the property damage and loss of limb that has already occurred as a result of Defendant's past activities, as well as the substantial risk to which he placed members of the general public recently and in connection with the activities resulting in his prior convictions,"Miller wrote.

In 2004, Feist was charged with possession of a bomb or explosive device after Andrew Greff detonated a pipe bomb at the "Desert," which blew off Greff's arm. Feist remains on probation for the resulting conviction and faces an April 17 revocation of probation hearing.

Earlier that year, Feist and Greff were charged with reckless endangerment after police found poisonous snakes in a Bismarck apartment. Feist was acquitted, but Greff pleaded guilty and was sentenced to one year in jail with six months suspended.

Feist's criminal history also includes convictions for setting off fireworks in a Burleigh County public bathroom and detonating a Molotov cocktail in Morton County.
