Failing to Register as a Sex Offender Lands Washington Man in Prison for Over Two Years

For Immediate Release
U.S. Attorney's Office, Northern District of Iowa

A man who lived and worked in Black Hawk County, Iowa, for nearly two years and failed to register as a sex offender was sentenced today to more than two years in federal prison.

Dean Christopher Upton, age 36, from Auburn, Washington, received the prison term after a June 21, 2021 guilty plea to failing to register as a sex offender.

At the guilty plea, Upton admitted that between the Spring of 2018 and February 2020, he lived and worked in Iowa and knowingly failed to register as a sex offender.  Upton was required to register as a sex offender based on a prior 2015 conviction for assault with a sexual motivation in the state of Washington.  Upton intentionally chose not to register as a sex offender and was apprehended while hiding in a cardboard box at his mother’s house in Waterloo.

Upton was sentenced in Cedar Rapids by United States District Court  Judge C.J. Williams.  Upton was sentenced to 30 months’ imprisonment and fined $100.  He must also serve a five-year term of supervised release after the prison term.  There is no parole in the federal system.

Upton is being held in the United States Marshal’s custody until he can be transported to a federal prison.

The case was prosecuted by Assistant United States Attorney Liz Dupuich and investigated by the United States Marshal’s Service.
