Bjorn Luster, of Cresco, Iowa, was sentenced on Monday to more than seven years in federal prison for alleged possession of an unregistered firearm, a destructive device.
Luster pleaded guilty to the charge on Sept. 19. Evidence in the case showed that law enforcement officers found a homemade bomb and a container of explosive powder while executing a search warrant at Luster's residence in January 2013.
Luster admitted to making the bomb, as well as wrapping it in BBs and nails to make it more destructive.
Luster received 87 months in prison in Cedar Rapids Detention Facility by United States District Court Chief Judge Linda R. Reade. Luster is also required to serve a term of three years supervised release after prison.
Luster is being held in custody of the United States Marshal until he can be transported to federal prison.
The case was prosecuted as part of Project Safe Neighborhoods. The project is a cooperative local, state and federal program that works toward greater prosecution of gun crimes.
The case was prosecuted by Assistant United States Attorney Daniel Tvedt, and was investigated by the Cresco Police Department, the Iowa Division of Narcotics Enforcement and the Bureau of Alcohol, Tobacco and Firearms.
