CHARICE Gassmann was today sentenced to life in prison for murdering Alison Connolly.

Charice, 19, was told she must serve at least 19 years before she will be considered for parole.

Sister Amberstasia, 23, was sentenced to 12 years for manslaughter and was told she must serve half of that before being considered for parole.

There were tears across the courtroom and shouts of “yes” from Alison’s family as the jury returned the verdict after five days of deliberations.

The jury of eight men and four women chose not to accept Charice acted due to a loss of self control or a personality disorder.

The court also heard Charice had previous convictions for violence including biting the face of a 14-year-old.

Judge Graham Cottle took just half an hour to come back with lengthy sentences for the sisters, which drew tears from Alison’s family.

He believed the two sisters were involved in a “joint enterprise” and both knew what was about to happen.

“There was pre-meditation there, a period of 10 minutes between the initial headbutt and the stabbing. You went over and armed yourself with a knife, you had violent intentions, to cause serious harm to Alison Connolly. You both were aware that violence was about to happen.

“You wanted to settle a score. Get revenge for what she had done to you. And you carried that out.”

Judge Cottle condemned Charice’s lack of remorse in the killing.

“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.”

Grandmother Alison was discovered in a communal stairwell at Evelyn House, Park South on May 12, having sustained a fatal stab wound.

Charice and Alison had got into an earlier altercation which resulted in Alison headbutting the teenager in a Cavendish Square Premier Store, causing her to bleed from a head wound.

Multiple witnesses had heard Charice say “I’m going to nank that bitch.” And “call the police, there’s going to be a murder.”

The sentencing brought the three-week trial of Charice and Amberstasia, sometimes referred to as 'the Gassman sisters', to a close.
