(Hillsboro, OR) -- Sentencing is set for next month for a man convicted of killing his mother in 2018 and then trying to have his brothers killed from jail. A Washington County jury found Michael Ross guilty yesterday of several charges, including second-degree murder and solicitation to commit first-degree murder. Court records say Ross killed his 73-year-old mother in her Tualatin home by stabbing her and then hitting her with a steel pipe. He also tried to hit his brother with the pipe, but he escaped. While in jail, Ross confessed to another inmate that he killed his mother and then offered to pay the inmate tens of thousands of dollars if he killed his two brothers after being released on bail. Ross reportedly anticipated a large inheritance and didn't want his brothers testifying against him.
