A Whatcom County man has admitted to a domestic violence assault that left his partner with serious injuries. Jason Sieber Sr., a 49-year-old member of the Lummi Nation, pleaded guilty to the assault which occurred on October 20, 2023. The admission was made in U.S. District Court in Seattle, as reported on October 8, 2024, by the U.S. Attorney's Office.
The altercation began when Sieber grew irate over the time it took for his partner to prepare dinner. He responded with violence, repeatedly striking her in the face and head, preventing her from fleeing to seek assistance. The victim suffered facial fractures and endured both extreme pain and subsequent disfigurement. Federal sentencing guidelines could see Sieber facing up to a decade behind bars. In a statement from the U.S. Attorney's Office, the victim reported the assault to the Lummi Nation Police days following the incident.
Initially, Sieber was charged in a tribal court before the case was referred to federal prosecutors. Since his arrest in February 2024, he has been held at the Federal Detention Center at SeaTac. The case highlights ongoing federal efforts to address serious crimes committed on tribal lands. The Safe Trails Taskforce, an initiative combining the resources of the Lummi Nation Police Department and the FBI, was responsible for the investigation leading to Sieber's arrest and plea.
The sentencing is set for December 20, 2024, with U.S. District Judge Ricardo S. Martinez presiding over the decision. Martinez will review the sentencing guidelines, alongside other considerations, to determine the punishment. The prosecution is being handled by Assistant United States Attorneys J. Tate London, who also serves as a Tribal Liaison, and Erika Evans, clarifies the U.S. Attorney's Office announcement.
