Seattle – A member of the Tulalip Tribes who engaged in sexual acts with a 14‑year-old child was sentenced today in U.S. District Court in Seattle to 33 months in prison, announced Acting U.S. Attorney Tessa M. Gorman.  Thomas Day, 24, repeatedly violated a no contact order issued by the Tulalip Tribal Court when he pursued sex acts with the 14-year-old.  At the sentencing hearing, Chief U.S. District Court Judge Ricardo S. Martinez said, “he kept up this conduct even after he knew he was under law enforcement investigation.”

According to records filed in the case, between July and August 2019, Day continued to communicate with the 14-year-old a despite court order barring contact.  Day met up with the child and took her to a residence on the Swinomish Tribal Reservation where they engaged in sex acts.  The child was almost ten years younger than Day, and he had been told repeatedly by courts, law enforcement, and family members to leave the teen alone.

Day will be on supervised release for ten years following the prison term and will be required to register as a sex offender.

The case was investigated by the Tulalip Tribal Police, Swinomish Police Department and the FBI.

The case was prosecuted by Assistant United States Attorney Rebecca Cohen.
