Sarah Williams has been jailed for life for brutally murdering Sadie Hartley in a plot described as a ‘game of death’.
She knocked out Ms Hartley with a stun gun before repeatedly stabbing her at the victim’s home in the village of Helmshore, Lancashire.
The jury had heard how ‘bunny boiler’ Williams had become obsessed with Ms Hartley’s partner, former fireman Ian Johnston.
She spent months plotting the attack with her friend Katrina Walsh, who was also convicted of murder today.

Williams was ordered to serve a minimum 30-year life sentence. Walsh will spend at least 25 years behind bars.
Passing sentence, judge Mr Justice Turner said ‘loving mother’ Ms Hartley was ‘slaughtered like an animal’.
He told the pair: ‘Neither of you have shown the slightest remorse… let no-one believe this was a crime of passion. It was a crime of obsession, of arrogance and of barbarity, but above all a crime of pure evil.’
Williams swallowed hard as the forewoman delivered the guilty verdict today, while Walsh, who has alopecia, gave a slight nod of her head.
Ms Hartley’s daughter, Charlotte, wiped away tears as she sat in the public gallery next to Garry Hartley, her father and Sadie’s ex-husband, and her brother, Harry.

Mr Johnston, sitting a few rows behind them, had tears in his eyes and gave a slight nod as the verdicts came in.
In an interview recorded ahead of today’s verdicts, Mr Johnston sobbed as he admitted he would always regret sending explicit messages to Sadie’s killer days before she was murdered on her doorstep.
