No one will ever know why a woman launched a "chilling and frenzied attack" and stabbed her best friend 18 times.
Lauren Walsh, 22, savagely knifed Kelsey Gielinck after accusing her best mate of killing her nan - who is still alive.
When the attack was interrupted by Miss Gielinck's boyfriend, Wesley Pemberton, Walsh also stabbed him three times.

In December of 2021, Walsh, of Packenham Road in West Derby, was found guilty of her two counts of attempted murder at Liverpool Crown Court and the case was adjourned for sentencing.
Today Walsh appeared before the court to hear whether she would receive an extended sentence - for offenders found to be dangerous - or whether she would be handed a life sentence.
Judge David Aubrey, QC, said that previously, the jury was satisfied Walsh "intended to kill" both of her victims and a psychiatric report was ordered.
Walsh, wearing a red coat, was produced in the dock this afternoon.
The judge added: "Your case has many unusual factors. The question not answered during the course of the trial was why you did what you did.
"You gave no explanation at the trial, in my judgement it still hasn't been answered. Only one person knows why and that is you."
The court heard how Walsh gave no explanation to doctors and despite the friends describing each other as "joined at the hip", Walsh "broke that trust".
Walsh had stolen Miss Gielinck's bank card and later that day carried out a "chilling attack" after taking a large knife out of Miss Gielinick's kitchen.
For the offence of theft, there was no separate penalty as the judge said this offence "pales in significance" to the events to come on that day.
Judge Aubrey said: "All was normal until you went into the kitchen, armed yourself with a butcher's knife, a lethal weapon which you possessed."
The judge said Walsh "locked the front door" at some point, which suggested an element of planning.
He added that Miss Gielinck, who was present in the public gallery with her loved ones, was stabbed repeatedly in a furious attack but "bizarrely" Walsh was shouting "you killed my nan".
The court heard how Walsh was "showing no emotion" but fortunately, none of the injuries penetrated an internal organ, but it could have ended differently.
Judge Aubrey said there was a "potential risk to life", therefore the jury was satisfied she had intended to kill both victims.
The court also heard how Mr Pemberton came downstairs before he too was stabbed three times.
The judge added how "regrettably" the court could not provide answers as to why, adding: "This court has heard powerful victim personal statements."
He went on to say: "They spend as little time at the house, which brings back memories."
The court heard how Walsh's mitigation was her young age, her previous good character and these were taken into account when sentencing.
However, the judge said he was "satisfied" there was no evidence of mental illness or disorder from the psychiatric reports, albeit there may be some evidence of an emotionally unstable personality disorder.
He added he was also satisfied the psychiatric report did not provide any evidence that might reduce culpability.
The court heard how Walsh had "picked up the largest knife", which in Judge Aubrey judgement suggested she was "waiting for the opportunity".
Judge Aubrey added Walsh "walked without emotion" into the living room and attacked her friend in a "chilling" series of events, which were "anything but spontaneous or impulsive".
The judge said there was a "significant risk" to the public and that he had to take that into account when sentencing.
He said Walsh was a "troubled person" and it was a "troubling case", but he was satisfied Walsh was "dangerous" and only a life sentence could be justified.
Sentencing Walsh, he said life sentences were a "last resort" but any other sentence would "not be sufficient".
Giving a concurrent sentence for both counts of attempted murder, he said Walsh would serve a minimum of 14 years and eight months before she can apply for parole.
In a stark warning to Walsh, Judge Aubrey said that did not mean she will be released at that stage.
The judge also awarded £250 to neighbour Paul Martin, who intervened in the attack, adding: "This is a modest amount for coming to help the victims without any concern for his safety.
"But nonetheless, he is recognised for his doing."
