A man who ran over and killed a 17-year-old girl working in a Lower Valley field on the Yakama reservation pleaded guilty to involuntary manslaughter Thursday in U.S. District Court.
Joshua Sampson’s guilty plea comes after more than two years and five trial postponements. Sampson’s initial plea was innocent, but he changed that during Thursday’s status hearing.
Sampson is accused of driving onto a Progressive Road field and running over and killing Petrona Mendez Ruiz on June 1, 2019. The SUV Sampson was driving had to be lifted off her body.
Ruiz came here from Guatemala with her father to work.
Her father, Roberto Mendez Garcia, was working in a neighboring field and was called over to identify his daughter’s crushed body.
Yakima County Sheriff’s deputies and Yakama Tribal Police responded and Sampson was arrested at the scene. Deputies said Sampson reeked of alcohol.
Sampson was tried in federal court because he is Native American and the incident occurred on the Yakama reservation.
In federal court, involuntary manslaughter carries a maximum penalty of eight years in prison and a $250,000 fine.
Sampson was released to attend substance abuse treatment and will return to custody when his treatment is complete, according to court documents.
