What happened to Becky Godden-Edwards, how accurate is ITV’s A Confession and where is Christopher Halliwell now?
TRAGIC Becky Godden-Edwards was just 20 when depraved Christopher Halliwell strangled her to death in 2003.
Here's what we know about Becky and her evil killer.
Who was Becky Godden and what happened to her?
Becky Godden was a sex worker who disappeared from Swindon.
She was known to Halliwell, who had become besotted with her after meeting her while working as a taxi driver in the red-light district the Wiltshire town.
In January 2003, he had sex with Becky, strangled her and buried her body in a field in Gloucestershire.
But her murder only came to light in 2011 when Halliwell was arrested over the disappearance of personal assistant Sian O'Callaghan, 22.
After leading cops to the spot where he had dumped Sian's body - and subsequently charged with her murder - he offered detectives "another one".
He then took officers to the place where he'd buried Becky's headless corpse eight years earlier.
He told officers he was a “sick f***er” and asked: “Is it too late to get help?”
He then said: “I know you aren’t a psychologist but what the f***’s wrong? Normal people don’t go round killing.”
Despite initially denying Becky's murder, Halliwell admitted taking a girl from Swindon between 2003 and 2005, when he "had sex with her and then strangled her".
But even after confessing he was able to dodge justice for Becky’s killing on a technicality.
Senior investigating officer Steve Fulcher was found not to have followed procedures on the treatment of suspects, meaning Halliwell’s confession was inadmissible in court.
Eventually new evidence was uncovered, allowing police to bring the killer cabbie back in for questioning over Becky’s murder.
Evidence from a former prostitute who said Halliwell was “besotted” with Becky, and forensic evidence linking his shovel to the field where she was buried, were enough to send Halliwell down at the second attempt.
A judge slammed his “cock and bull” defence as he passed a whole life tariff - reserved for the most dangerous criminals such as serial killers.
Halliwell was already serving life for Sian's murder when he was sentenced for killing Becky in September 2016.
In a heartbreaking victim impact statement, Becky's mum Karen Edwards said: "I never had a body to kiss goodbye before she was buried. But of course she had already been buried, in a lonely field in the middle of nowhere, for years. Just left to rot.
"She was brought back home in that coffin. I was told not to open it and the reason for that was because all that was in it was just my daughter’s bones, and part of Becky’s skeleton.
“Where was her head? Well that has never been found … I stayed with her coffin for three weeks until the day of her funeral.”
Is Christopher Halliwell a serial killer?
Officers who dealt with Halliwell believe he may have killed other victims besides Sian and Becky.
In a police interview he said he could not remember which year he killed Becky, suggesting there were others.
A former cellmate said the cabbie was obsessed with Moors murderer Myra Hindley and was fixated on becoming a serial killer.
Ex-armed robber Ernest Springer, 64, said: “He used to ask me about killing. He said, ‘How many people do you need to kill before you become a serial killer?’
“He just had a thing about them. He wanted people to be proud of him or an area to be afraid of him.
“Don’t ask me why, but that's what he wanted to be. He used to get this magazine called True Detective with stories about people getting knocked off.
“His favourite book was about the Moors Murders with a picture of Myra Hindley on the front."
Halliwell has been linked with a string of suspected murders in the Swindon area over the years after hinting that he had other crimes to hide.
When being quizzed for the second time over Becky's death, he told police: “I don’t want to keep coming back every couple of years on different charges."
He added: “If I can clear this up in the next few hours, will everything else be forgotten?”
Melanie Hall, 25, disappeared after leaving a nightclub in Bath in 1996. Her body was found by the M5 in 2009.
Halliwell reportedly once told a colleague at his minicab firm: “Who knows what or who you will find buried out there, there could be loads of people over the years.”
Another potential victim is prostitute Sally Ann John, 24, who vanished from Swindon in 1995. She and Halliwell lived on the same street at the time.
Tina Pryer, 39, Thi Hai Nguyen, 20, and Sandra Brewin, 21, have also been missing for years.
And Linda Razzell, 41, disappeared in the Wiltshire town in 2002.
Her husband Glyn has spent 13 years in jail for her murder but maintains he is innocent.
It has emerged Halliwell was obsessed with Linda after doing building work at the Razzells' home four years before she was killed.
Incredibly, the date Linda went missing in 2002 — March 19 — links Halliwell, his second known victim Sian and another unsolved case.

Is ITV's A Confession accurate?
Following on the success of Manhunt, A Confession is another crime drama which deals with a real-life case.
It tells the story of 22-year-old Sian O’Callaghan who went missing in Swindon in 2011 after leaving a nightclub to walk to her boyfriend's house.
Senior Investigating Officer Steve Fulcher is in charge of handling the case and firmly believes that Sian is still alive.
In the end he links Sian's case to the disappearance of Becky Godden-Edwards and breaches police procedure to ensure that justice prevails.
