Darien Man Sentenced to Two Years for Illegal Gun Possession

MADISON, Wis. — Timothy M. O’Shea, U.S. Attorney for the Western District of Wisconsin, announced that Arron W. Dupler, 34, of Darien, was sentenced today by U.S. District Judge William M. Conley to two years in prison for possessing a firearm as a felon. Dupler’s federal sentence will run consecutive to two undischarged state sentences. He pleaded guilty to the federal charge on No. 1, 2023. 

Law enforcement began investigating Dupler after receiving information that he was posting pictures of guns on Facebook and offering the guns for sale. On March 4, 2022, Dupler sold an undercover police officer a Ruger LCP .380 handgun. Dupler showed the officer pictures of additional guns that he had previously sold and said he could get more. Dupler is prohibited from possessing firearms as a result of two felony convictions from 2007 and 2018.

At sentencing, Judge Conley said that the most disturbing part of Dupler’s offense was his comment to the undercover officer that the gun had “no bodies” on it, and that only five rounds had been fired from the gun. Judge Conley noted that these attributes would make the gun harder to trace, should it be used in criminal activity. 

The charge against Dupler was the result of an investigation conducted by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Janesville Police Department and the Wisconsin Department of Justice Division of Criminal Investigation. Assistant U.S. Attorneys Anita Marie Boor and Megan Stelljes prosecuted this case.
