Brian H. Jones Sr. of Tulalip faces almost 100 years in prison after being convicted Jan. 21 of assault by strangulation, witness tampering and other charges in U.S. District Court in Seattle.

U.S. Attorney Annette L. Hayes said following a six-day trial, Jones Sr., 46, only had to wait six hours for jury deliberation.

Court papers and testimony say:

Jones assaulted both his ex-wife and her then-current husband in December 2014, holding them at gunpoint. In April 2015, Jones assaulted his ex-wife a second time, strangling and beating her.

Medical records indicate Jones’ ex-wife suffered injuries to her head, arms and legs, and throat trauma.

Following his arrest in both assaults, records reveal Jones repeatedly contacted his ex-wife and convinced her to refuse to testify in a tribal court trial, as well as to seek a dismissal of the federal charges or recant in federal court.

Prosecutors used evidence including the ex-wife’s prior sworn statements, medical records and other witness statements to prove Jones’ guilt.

U.S. District Judge Richard A. Jones scheduled sentencing for May 6.

Jones faces up to 20 years in prison for each of the crimes of assault by strangulation, assault resulting in serious bodily injury, assault with a deadly weapon and witness tampering.  He also faces up to 10 years for being a felon in possession of a firearm. He faces a mandatory minimum term of seven years in prison consecutive to the other sentences for assault with a deadly weapon.

The case was investigated by Tulalip Tribal police and the FBI.
