A NEW Sky true crime series will cover the brutal murders carried out by Christopher, now Crystal, Hunnisett.
But who is she? Here’s all you need to know…
Who is Christopher Hunnisett?
She began identifying as woman while serving her sentence and changed her name to Crystal.
While behind bars the former altar boy castrated herself and mutilated her genitals in a botched DIY surgery.
How many people did they kill?
Crystal had been found guilty of murdering two men – but has had one conviction quashed.
In 2001 Christopher, 17, killed 17-year-old Reverend Ronald Glazebrook who he had been lodging with in St Leonards on Sea, in East Sussex.
After the murder he recruited a friend to help him tear apart the body.
His severed head and limbs were found with a saw in a sports bag on a traffic island in Hastings.
A couple of days later his torso was found near Eastbourne.
He was convicted of murder and given an indefinite prison term with a minimum of eleven years.
However he had the conviction quashed after a repeal eight years into his sentence.
He told jurors he punched the Reverend to stop her touching him in the bath – and that the next day he found him dead.
Just four months after being released from prison at the age of 28, Christopher had sex with 57-year-old grocery store clerk Peter Bick.
He then attacked him, hit him repeatedly on the head with a hammer and strangled him with a shoelace.
He claimed that she had killed Bick as part of her mission to rid the world of peadophiles.
However at his trial in 2012 the court heard there was “not a shred of evidence” that he was a paedophile.
Christopher denied murder on the grounds of loss of control and diminished responsibility but was convicted and jailed for life with a minimum 18-year sentence.
In October 2015 she began identifying as a woman.
She claimed that her rights were being violated by prison staff who had been keeping her isolated from other lags for her own safety.
She told the High Court that he had been mistreated by staff who were showing contempt towards transgender prisoners – and claimed it was a violation of his human rights.
His claim was rejected.
When will Crystal Hunnisett be released?
In March 2021 Crystal again argued for an appeal of her murder conviction.
She claimed that a psychotic illness had caused her to believe Bick was a paedophile.
However three judges found “no proper basis to admit the fresh evidence”.
She will now remain in prison for the remained of her sentence – with an earliest release of 2030.
