Minocqua sex offender federally indicted

January 14, 2020 by Abigail Bostwick

In addition to county charges, a Minocqua registered sex offender will now answer to a federal indictment for new crimes. 

Matthew K. Kummer, 49, Minocqua, was in Oneida County Circuit Court in December 2019, where he pled not guilty to felonies fail to maintain sex offender registry, two counts registered sex offender intentionally photograph a minor without consent, knowingly fail to notify a school of sex offender status and 10 count possession of child pornography. 

Last week, the Office of U.S. Attorney Scott C. Blader, Western District of Wisconsin US Department of Justice, handed down an indictment on Kummer, alleging that in October 2019, Kummer had a USB drive with pictures of minors “engaging in sexually explicit conduct,” including at least one under the age of 12.

If convicted federally, Kummer faces up to 20 years in federal prison.

Handling the case is assistant US attorney Elizabeth Altman. 

The federal case came as a result of Oneida County Sheriff’s Department investigation, along with the Wisconsin Department of Justice Division of Criminal Investigation and Minocqua and Woodruff police departments. 

In Oneida County, Kummer is defended by attorney Mary Roth Burns. Judge Michael Bloom will rule on the case, currently set for pre-trial in February. 


It was 2008 when then-Rhinelander resident Kummer was convicted of possessing child pornography. He had pled not guilty to those counts and was initially facing another 17 of the same counts. Those were dismissed and read into the record at sentencing before Judge Mark Mangerson. As part of the sentence, Kummer was mandated to file with the state sex offender registry, at least until 2026. 

The autumn 2019 charges allege Kummer of going to Rhinelander Middle School to pick up a friend’s daughter and not notifying the school or updating his address with the state, as outlined in his sentence. A county deputy saw and questioned Kummer that day, where he admitted he was a registered sex offender. 

A subsequent search of Kummer’s home uncovered the child pornography images that it appeared he took himself in local areas, as well as a number of other child pornography images, court records say.

Further, Kummer was charged with contempt of court late in November 2019. Jail staff found out Kummer was allegedly having a video chat with two juvenile females while in their custody. The girls, ages 12 and 16, were found to be Kummer’s sister’s children. Kummer was having regular contact with the girls. As part of Kummer’s bond, he is not allowed to have contact with minors. 

Kummer remains behind bars in Oneida County Jail on a $100,000 cash bond.
