West Mercia Police has released this image of Jamie Reynolds casually going to the cinema in Wrexham on the way to disposing of Georgia Williams' body in nearby woodland off the Nant-y-Garth Pass in May.
Reynolds, 23 and from Shropshire, has been given a whole-life jail term today, for murdering the 17-year-old.
A 23-year-old man killed teenager Georgia Williams after luring her to his parents' house and hanging her, a court has heard.
Jamie Reynolds was a "a sexual deviant", "a manipulative and conning individual who operated in denial" and had "a morbid fascination" in extreme pornography depicting violence against women, prosecutor David Crigman QC said.
Reynolds pleaded guilty earlier this month to murdering 17-year-old Georgia in May, on what was scheduled to be the first day of his trial at Stafford Crown Court.
Mr Crigman said that at the time of his arrest for murder, Reynolds had 16,800 images and 72 videos of extreme pornography on his computer, including digitally-doctored images of up to eight other women he personally knew in which ropes had been added around their necks.
Superintendent Adrian McGee has given his reaction after 22-year-old Jamie Reynolds pleaded guilty to the murder of 17-year-old Georgia Williams.
She was murdered at Reynolds’ home address on Avondale Road, Wellington, on 26 May.
Reynolds is due to be sentenced later this month.
Speaking outside the court following the plea, Supt McGee - who was one of the senior investigating officers in this case said:
“It is important that Mr Reynolds pleaded guilty today as this at least saves Georgia’s family the further trauma of a full trial. We know the plea does nothing to ease their pain but hopefully it will help them begin to move forward with their lives once sentence is passed.
"The Williams family have been incredibly dignified and understanding throughout our investigation and I cannot praise them highly enough.
"This was a hugely challenging and unusual case for the police officers and staff involved and I’d like to thank everyone who has played a part in helping the investigation reach this point.
"I’d particularly like to thank all the witnesses who came forward with information to assist our investigation, while I’d also like to thank the media for their help in publicising our appeals and helping us find Georgia and return her to her family.
"At the present time we do not wish to make further comment until sentencing takes place later in the month.”
