A couple who relished their relationship of “sado-masochistic violence” killed a woman in a “premeditated blood-thirsty murder” and dumped her dismembered body in a park, the Old Bailey has heard.
Steve Sansom was out of prison on life licence for another murder when he killed Sarah Mayhew, 38, and dumped her remains in Rowdown Fields, New Addington, south London, last spring.
