Michael Gorbey, 38, pled not guilty to the charges at an appearance in Superior Court on Monday. He had already been charged with being a felon in possession of a firearm, but the bomb charge is new.

The 15 charges, according to court documents, include the “manufacture, transfer, use, possession or transportation of explosives for unlawful purposes” and the “attempted manufacture or possession of a weapon of mass destruction.”

Gorbey, who is being held without bond, represented himself on Monday with public defender Jason Tulley acting as his stand-by counsel.

Judge Gregory Jackson denied Gorbey’s motion for a change of venue. Gorbey’s had argued that media coverage in the District would make it difficult for him to get a fair trial, but Jackson said he did not consider coverage to be “the kind of publicity or kind of reporting that would make it difficult to select a jury that would be impartial.”

Jackson did not rule on Gorbey’s motion to suppress evidence. However, he and the assistant U.S. attorney prosecuting the charges agreed to arrange a way for Gorbey to review the evidence. That evidence includes “thousands of pieces of paper” gathered from the truck and a backpack Gorbey was wearing when he was arrested, weapons, photographs and videotape of Gorbey, according to Assistant U.S. Attorney Jennifer Kerkhoff.

When Gorbey was arrested, police said they found four knives, more than 30 rounds of ammunition, a sword and a military flak jacket on his person. According to court documents, they also recovered numerous papers, including the title to the truck Gorbey was driving, which was registered in his girlfriend’s name,

Police said they found the explosive materials in the truck on Feb. 8, weeks after his arrest. Initially, police said it found “hundreds of rounds of ammunition,” a zip gun, clothing and food, making it seem “as if someone was living out of the truck” according to court documents.

Gorbey’s next status conference is scheduled for April 15.
