Seattle – A 22-year-old member of the Nooksack Indian Tribe was sentenced today in U.S. District Court in Seattle to 42 months in prison and 15 years of supervised release, for sexual abuse of a minor, announced U.S. Attorney Nick Brown.  Kamron Dylan Duane Cooper, was indicted in February 2020, and pleaded guilty in June 2121.  At the sentencing hearing U.S. District Judge Robert S. Lasnik said that the young girls Cooper victimized will continue to suffer emotionally from their sexual abuse and that the sentence imposed recognizes the harm he has caused.

According to records filed in the case, between March 2018 and January 2019, Cooper engaged in sex acts with a 13-year-old on the Lummi Reservation.  Cooper groomed the teen, persuading her to engage in sexual activity.  Cooper was on supervised release at the time for juvenile offenses involving sexual assaults on two 14-year-old girls.  Those assaults also occurred on the Lummi Reservation. 

Cooper will be required to register as a sex offender following his prison term.  As part of his 15-years of supervised release, Cooper will undergo sex offender treatment.

The case was investigated by the Lummi Nation Police Department and the FBI.

The case was prosecuted by Assistant United States Attorney J. Tate London.  Mr. London serves as a Tribal Liaison for the U.S. Attorney’s Office, Western District of Washington.
