A MUM-of-eight’s killer will be released from prison this year, it has been confirmed.

But the Ministry of Justice has refused to say exactly when Amberstasia Gassmann would be released.

The 28-year-old was found guilty of manslaughter in 2015 and told she would serve half her 12 year prison sentence behind bars. Her sister, Charice, was given life for the murder of 49-year-old Alison Connolly in Park South.

The Ministry of Justice refused to confirm whether the conditions of her licence would include a ban on entering Swindon.

A spokesman for the department said: “This was an appalling crime and our thoughts remain with Alison Connolly’s family.

“Prisoners released under supervision face strict conditions, which can include GPS tags and exclusion zones, and can be returned to prison if they breach them.”

In 2015, a Bristol jury heard how then teenager Charice Gassmann stabbed Mrs Connolly in the chest with a kitchen knife after a fracas in a shop in Cavendish Square.

The older woman had confronted the teen over brown sauce being left on her daughter’s pushbike. She headbutted Gassmann but had later wanted to apologise to the girl and asked a friend to find her.

In court, Charice Gassmann was described as a “bully out for revenge”. After the incident in the shop, she was heard shouting: “Call the police, there's going to be a murder.”

Her sister Amberstasia was heard to shout after the fatal stabbing: “That's what happens when you mess with my family.”

Although Charice Gassmann denied the charge of murder she pleaded guilty to manslaughter on the grounds of diminished responsibility.

Her defence lawyers told the court that she had experienced a loss of control due to a personality disorder that she suffers from.

But after being in retirement for five days the jury convicted her of murder, with members of the victim's family shouting "yes" as the verdict was returned. Amberstasia was cleared of murder by the jury of eight men and four women but convicted of manslaughter.

Judge Graham Cottle told Charice: “You sent me a letter telling you were remorseful. Watching you over the weeks I have seen few signs of genuine remorse. All I have seen is signs of anger and irritability as you dealt with questions.”

In 2017, both sisters lost an appeal – Charice against conviction and Amberstasia against her sentence.

Lady Justice Hallett said there was "ample evidence" on which the trial judge could conclude that Amberstasia knew her sister had a knife and intended violence.

Charice had made her intent "all too clear", she said. "Amberstasia was, therefore, a knowing party to an armed revenge mission, as the judge found, albeit not a party with the proven intent to kill or cause really serious bodily harm.”
