       Ms Douglas, from Colton, a village west of Norwich, was reported missing by family members on October 21 2021.

       Norfolk Police launched a ‘no body’ murder investigation after inquiries found Ms Douglas had not been seen for a “significant period”.

       Ms Douglas’s remains were then found in the garden of a house in Barford Road, Colton, on November 2, the force said.

       A Home Office post-mortem examination established the provisional cause of death as unascertained due to the state of decomposition, with further examination to be carried out.

       Williamson, of Barford Road in Colton, had been arrested in Wales on October 30 and was later charged with murder.

       He had yet to enter a plea to the charge and was remanded in custody, facing a trial at Norwich Crown Court in April.
