A man who had already been convicted of felony arson was sentenced to 10 years in federal prison for building and firing two improvised explosive missiles.
Daniel Graben, 60, of Sioux City, Iowa, received the prison term after a guilty plea to possession of a firearm by a felon on July 18, 2024.
Evidence in the case revealed that Graben, who had a history of violence, had built and fired two improvised explosive missiles in February 2022. The missiles were seen flying over a house in rural Plymouth County, causing explosions in the distance.
Law enforcement discovered the wreckage of the missiles and connected them to Graben. A search of his home in Sioux City found firearms, ammunition, powerful military-grade explosive material, and bomb-making materials.
Graben had previously been convicted of arson and threatening a crime with intent to terrorize another in California in 2008, and possession with the intent to deliver a controlled substance in Idaho in 2012.
He was sentenced to 120 months’ imprisonment by United States District Court Judge Leonard T. Strand. Graben must also serve a 3-year term of supervised release after the prison term and pay a fine.
The case was brought as part of Project Safe Neighborhoods (PSN), a program that focuses enforcement efforts on the most violent offenders and partners with locally based prevention and reentry programs for lasting reductions in crime.
