(Hillsboro, OR) -- A man who was on the run from the law for more than a decade will be spending the rest of his life behind bars. A jury in Washington County convicted Efrain Sanchez-Diaz of the 1999 stabbing death of his ex-girlfriend, 21-year-old Maria Garcia Leonardo, at a Burger King in Tigard. Authorities say Sanchez-Diaz fled to Mexico following his indictment, six months after Leonardo's death. Sanchez-Diaz was extradited to the U.S. last year after he was found in Acapulco.
