On 20 August 2001 Tiernan's body was found by Mark Bisson, who was walking his two dogs in Lindley Woods, North Yorkshire, 100 yards from where another murder victim, Yvonne Fitt, had been discovered buried in 1992 [REF].
The state of decomposition of Tiernan's body led some forensic experts to believe that after her death she had been kept in cold storage or a freezer up until a few weeks before the body was found, in part to avoid detection and in part as a trophy [REF].
