The killer, Jamie Reynolds, is reported to have taken ‘before and after’ photos of the victim at his home in Shropshire in May.
The Times newspaper describes Reynolds, 23, as a ‘photographer’ who was addicted to extreme pornography.
However, when contacted by Amateur Photographer, Stafford Crown Court declined to say whether or not Reynolds worked as a photographer.
Reynolds, who is described in other press reports as a ‘shop worker’, will be sentenced on 19 December.
He has been remanded in custody pending psychiatric reports.
Georgia Williams was the daughter of a police detective.
