Donald Graham has been found guilty of the murder of Hexham heiress Janet Brown.
A jury at Newcastle Crown Court found the 60-year-old, formerly of Elsdon Avenue in Seaton Delaval, unanimously guilty of murder and perverting the course of justice.
It follows the disappearance of Miss Brown nine years ago, who was described during the trial as disappearing off the face of the earth.
Graham killed Miss Brown and then drained her assets for his financial gain.
Miss brown’s body has never been found.
