Child Sexual Predator Sentenced to 25 Years in Federal Prison

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

PORTLAND, Ore. – On Thursday, March 30, 2017, United States District Court Judge Marco A. Hernández sentenced Kilunnun Adyden Chivoski, 41, to 25 years in federal prison followed by a lifetime of supervised release and sex offender registration. In September 2016, a federal jury in Portland convicted Chivoski of one count of transporting a minor across state lines with the intent to engage in criminal sexual activity.

Evidence presented during the ten-day trial showed Chivoski engaged in the repeated, systematic sexual abuse of two children that he had taken steps to isolate and indoctrinate over a yearlong period. Chivoski’s crimes were discovered years later when his victims began disclosing the abuse. Investigators meticulously pieced together Chivoski’s extensive cross-country travel, seeking to establish locations where he committed the abusive acts.

Though the intervening years and Chivoski’s itinerant lifestyle presented difficulties for the prosecution, the government successfully presented evidence that he had sexually abused the children during a cross-country road trip terminating in Oregon in August 2010. Evidence further established that one of Chivoski’s dominant, significant, and/or motivating purposes for that trip was to facilitate his continued sexual abuse of one of the minors.

At sentencing, prosecutors urged the court to impose a thirty-year prison term, followed by lifetime supervised release and sex offender registration. Chivoski’s conduct, they argued, was "shockingly heinous," as he sought to isolate and brainwash his pre-teen victims to avoid detection and continue his abuse. In response, Chivoski sought the mandatory minimum sentence of ten years in prison.

"This sentence will protect children in Oregon and elsewhere from a sexual predator whose egregious crimes will have a lifelong impact on his victims," said Billy J. Williams, United States Attorney for the District of Oregon. "I am grateful for the dedication and collaboration of our federal, state, and local partners who diligently followed the evidence in this case as part of their continuing effort to protect children in our district. I am also grateful for the amazing bravery that Chivoski’s victims showed," added U.S. Attorney Williams, "in coming forward to seek justice. Thanks to their courage, our community is safer and a dangerous criminal is behind bars."

In imposing the twenty-five-year prison sentence, Judge Hernandez remarked, "it is always troubling to the court when you think about parents abusing their own children and while

Mr. Chivoski’s own paranoia and mental challenges contributed to his actions, it doesn’t make his children any less of victims. He needs to be held responsible for this abuse."

This case was investigated by the Clackamas County Sheriff’s Office and the Department of Homeland Security’s Homeland Security Investigations (HSI) and prosecuted by Jane Shoemaker and Ravi Sinha, Assistant United States Attorneys for the District of Oregon.

The case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse. Launched in May 2006 by the U.S. Department of Justice and led by United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section (CEOS), Project Safe Childhood marshals federal, state, and local resources to better locate, apprehend, and prosecute individuals who exploit children via the Internet, as well as to identify and rescue victims.
