Justin M. Jasper, 22, was arrested July 3 near the University of Washington and was charged Tuesday in King County Court with possessing an incendiary device, two stolen guns and a truck stolen from a man who befriended him in Montana, King County prosecutors said.
On Wednesday, Jasper was charged with five federal crimes, including transportation of a stolen vehicle; possession of a stolen vehicle; possession of stolen firearms; possession of destructive devices; and possession of explosives during the commission of a felony, according to U.S. Attorney Jenny A. Durkan.
When Jasper was arrested in the stolen truck, he was in possession of six homemade firebombs, a double-barreled shotgun, a long rifle with a scope, body armor and multiple knives, according to court papers.
Authorities say Jasper also had maps to three Seattle campuses and a recording in which he said he planned to do something in the West to support protesters demanding reform in Brazil.
Four of the federal counts have a maximum penalty of 10 years in prison. Possession of explosives during the commission of a felony carries a mandatory minimum 10-year sentence in addition to any other sentence imposed in the case, Durkin wrote in a Wednesday news release.
Jasper will make his initial appearance in U.S. District Court on Thursday.
