Mabton convict shot, killed armed associate who entered his home

MABTON, Wash. — Criminal investigators in Yakima County are probing a Sunday night homicide in which a homeowner and convicted felon allegedly shot and killed a man who he worked for in an illegal operation.

According to the Yakima County Sheriff’s Office, deputies were sent to a home on the 5300-block of Sunnyside Mabton Rd for reports that a man suffered a gunshot wound during a violent altercation. When they arrived, deputies found the man dead with a shotgun wound.

Authorities say the victim was armed with a gun in his waistband when he entered the residence uninvited on the evening of July 17, 2022. The homeowner allegedly armed himself with a shotgun and the two men exited the home, moving the confrontation outside.

That’s when the homeowner, since identified as 47-year-old Mabton resident Jon Ray Bonewell Jr., allegedly shot the invader—30-year-old Mathew James Rand of Grandview. However, during subsequent interviews with Yakima County law enforcement, Bonewell Jr. allegedly admitted to being a convicted felon who was not legally allowed to possess a firearm.

Furthermore, YCSO officials say Bonewell Jr. worked for Rand in an illegal operation in which they sold stolen goods. Bonewell Jr. told interviewers that Rand was angry about the rate at which these items were being sold.

Bonewell Jr., who told Yakima County investigators that he thought Rand was preparing to shoot him, was booked into the Yakima County Jail for second-degree murder and unlawful possession of a firearm to the first degree.

Anyone with information that may assist with this investigation is urged to contact Detective Garcia via email at or call YCSO at (509) 574-2500.
