United States Attorney Alison J. Ramsdell announced that Daniel J. Kubica, also known as “Danny Haddreck,” from Niles, Illinois, has been sentenced to 24 years in federal prison. The sentencing was carried out by U.S. District Judge Karen E. Schreier on May 30, 2025. Kubica was convicted of three counts of sex trafficking by force, fraud, or coercion and one count of money laundering.
Kubica will also serve five years of supervised release following his prison term and is required to pay $400 in special assessments to the Federal Crime Victims Fund. He was indicted by a federal grand jury in March 2023 and pleaded guilty on February 28, 2025.
Beginning no later than April 2021, Kubica operated an illegal sex trafficking ring involving multiple women around Rapid City. He coerced women into performing sex acts for money to support his fentanyl addiction. His methods included physical and sexual assaults and threats against the women if they attempted to leave the operation. In one instance, he provided drugs and alcohol to keep a victim engaged despite her addiction. Additionally, he threatened a victim and her sister with violence and sexually assaulted another woman to ensure her continued involvement.
From January 2022 to October 2023, Kubica used CashApp for financial transactions related to his trafficking activities. Payments were received either from clients or directly from the victims after engaging in sexual activities.
This case is part of Project Safe Childhood, an initiative launched by the Department of Justice in May 2006 aimed at combating child sexual exploitation and abuse. The project involves collaboration between federal, state, and local resources to prosecute offenders and rescue victims.
The investigation involved several agencies including the U.S. Department of Homeland Security – Homeland Security Investigations, Box Elder Police Department, Rapid City Police Department, Pennington County Sheriff’s Office, and South Dakota Internet Crimes Against Children Task Force. Assistant U.S. Attorney Heather Knox led the prosecution.
Following his sentencing, Kubica was taken into custody by the U.S. Marshals Service.
