United States Attorney Alison J. Ramsdell announced that a Deadwood, South Dakota, man has been indicted by a federal grand jury for Receipt of Child Pornography, Obscene Visual Representations of the Sexual Abuse of Children, and Possession of Child Pornography.
Dean Russell Schallenkamp, age 60, was indicted on April 22, 2022. He appeared before U.S. Magistrate Judge Daneta Wollmann on May 20, 2022, and pleaded not guilty to the Indictment.
The maximum penalty upon conviction is a mandatory minimum of five up to 20 years in federal prison and/or a $250,000 fine, mandatory minimum of five years up to lifetime supervised release, and a $100 assessment to the Federal Crime Victims Fund. Restitution may also be ordered.
Schallenkamp was federally indicted following a Cybertip from the National Center of Missing and Exploited Children generated by Microsoft. The charges relate to Schallenkamp receiving and possessing child pornography between March 2011 and September 2021, at Deadwood. The charges are merely an accusation and Schallenkamp is presumed innocent until and unless proven guilty.
The investigation is a joint effort between the Internet Crimes Against Children Taskforce, Homeland Security Investigations, South Dakota Division of Criminal Investigation, Rapid City Police Department, and the Pennington County Sheriff’s office. Assistant U.S. Attorney Sarah B. Collins is prosecuting the case.
Schallenkamp was released on conditions pending trial. A trial date has not been set.
