Pals’ reveal nickname for alleged cattle prod murderer who is accused of killing lover’s partner with ‘demonic savagery’
Sarah Williams is accused of incapacitating the partner of one of her lovers with a stun gun before stabbing her to death with 'demonic savagery'
MURDER accused Sarah Williams was branded a “bunny boiler” by pals, a court heard.
Williams, accused of of killing her lover's partner with "demonic savagery" had an affair with a second ski instructor who was married with two children, the jury was told.
She first had a relationship with Somapat Sitiwatjana, 47, after he taught her to ski at Manchester's Chill Factore indoor ski centre five years ago.
The fling allegedly ended before Williams went on to meet ski instructor Ian Johnston, 57, who was said to have jilted her after she became possessive and difficult.
The Crown says Williams's obsession with ex-fireman Mr Johnston drove her to murder his partner, Sadie Hartley, 60, at her home in Helmshore, Lancashire, on January 14 this year.
Williams, 35, a customer sales adviser at Crystal Ski Holidays - based at the Chill Factore - is said to have incapacitated Ms Hartley with a stun gun before stabbing her more than 40 times.

Williams’ pal Michaela Burns was asked by barrister Tony Cross: “You formed the view Sarah was a bunny boiler?”
She replied: “Yeah.”
Thai-born Mr Sitiwatjana, who runs a martial arts gym, said he broke off his relationship with Williams after she "got too close".
His wife of 25 years, Janet, found out he had been unfaithful when Williams visited the family home while he was away in Thailand in 2012, Preston Crown Court heard.
A letter was also sent to Mrs Sitiwatjna at around the same time.
Mr Sitiwatjana said he and Williams would meet up in hotels for sex but he did not see it as a serious relationship.
John McDermott QC, prosecuting, asked: "Did there come a time when she wanted it to be a serious relationship?"
Mr Sitiwatjana said: "She wanted to see more and more of me."
The prosecutor said: "Did you want that to happen?"
He replied: "No, because I have my own business to run and I have my own family."
Asked why he decided to end the affair, he said: "She got too close."
He said he returned to the UK from Thailand in September 2012 and he and his wife "talked it over".
He described how Williams went on to turn up unannounced at his gym in Manchester and park outside in her car.
Mr Sitiwatjana said she would drive off quickly when he spotted her, but on one occasion he asked why she was there and Williams told him she was seeing a friend.
He recalled an incident where all four tyres of his Mercedes Benz car were deflated in the Chill Factore car park.
He agreed with Gordon Cole QC, defending Williams, that he had told Williams he loved her "many, many times" in text messages and that they called each other "sweetie".
Some of the texts were also "very graphic sexual texts", he agreed.
He denied that Williams's then partner, 75-year-old businessman David Hardwick, was the cause of arguments between the pair during their affair.
Mr Cole said: "You had a view of David, that he was her 'sugar daddy'?"
The witness replied: "Yes, sir."
Mr Cole said: "And she didn't like you using that phrase?"
Mr Sitiwatjana said: "I don't remember."
Mr Cole said: "She would correct you when you used that phrase about David. She would say 'Don't say that, don't use that phrase'?"
The witness said: "I don't remember."
Mr Sitiwatjana also said he could not recall asking Williams to send photographs of her to him.
He said he did not remember either being in text message and WhatsApp contact with Williams while he was in Thailand and then again in October 2012.
Mr Cole asked: "Did you ever see her again and restart your relationship in May and June of 2013?"
Mr Sitiwatjana replied: "No, sir."
The court has previously heard that she sent a letter to Ms Hartley in September 2014 detailing her relationship with Mr Johnston.
Williams, of Blacon, Chester, denies murder. Her co-accused, horse riding instructor Katrina Walsh, 56, also denies murder.
Walsh is said to have helped her friend with the killing and allegedly wrote about staging the "perfect murder" in diaries recovered at her workplace.
