WATERLOO – An Illinois man who illegally possessed guns was sentenced to over nine years in prison in federal court in Cedar Rapids after a house was shot up.
Dillon D. Grundman, age 23, from Inverness, Illinois, received the sentence after a January 4, 2022 guilty plea to being an unlawful drug user in possession of multiple firearms.
In a plea agreement, Grundman admitted to traveling to Iowa and possessing four firearms. In December 2020, law enforcement investigated a shooting of a residence in Waterloo, Iowa, associated with Grundman’s ex-girlfriend’s family. Prior to the shooting, Grundman sent a “snap” of the rear of the residence from his Snapchat Account. Officers later discovered a note in Grundman’s phone with directions to the residence. After the shooting, officers located Grundman and recovered shell casings in his vehicle, which were consistent with the ones recovered inside the shot-up residence. In the plea agreement, Grundman also admitted to being an unlawful user of marijuana while in possession of the firearms.
Sentencing was held before United States District Court Judge C.J. Williams. Grundman was sentenced to serve 114 months’ imprisonment and must serve a 3‑year term of supervised release following his term of incarceration. There is no parole in the federal system. Grundman remains in the custody of the United States Marshal until he can be transported to federal prison.
The case was prosecuted by Assistant United States Attorney Jason D. Norwood and was investigated by a Federal Task Force composed of the Waterloo Police Department, Federal Bureau of Investigation, and Bureau of Alcohol, Tobacco, Firearms, and Explosives assisted by the Black Hawk County Sheriff’s Office and Cedar Falls Police Department.
