A 36-year-old man who was repeatedly violent to his partner before killing her has been jailed for a minimum of 19 years.
John Scott attacked Natasha Melendez, from Venezuela, at her home in Lisburn, Co Antrim, on 22 March 2020.
The 32-year-old died from her injuries ten days later.
Scott, with an address listed as Maghaberry Prison, was sentenced at Belfast Crown Court having earlier pleaded guilty to her murder.
The court heard that Ms Melendez had been beaten "beyond recognition" and had died after a "devastating stroke" which was the result of damage to a major artery supplying blood to her brain.
Prior to her death, she had expressed a fear that Scott, the father of one of her four children, would kill her.
The sentencing hearing was observed via video link by her mother Maria Mejias in Florida as well as other relatives.
Mr Justice O'Hara said the murder of Ms Melendez was the end result of Scott’s "repeated violence against her".
He also pleaded guilty to charges of grievous bodily harm with intent, assault occasioning actual bodily harm, and common assault against Ms Melendez.
These spanned a period between 1 December 2019 and March 2020.
The court was told they included an "exceptionally violent" incident in which Scott threw a vacuum cleaner at the victim and jumped hard and repeatedly on her prone body while holding on to a headboard, resulting in broken ribs and facial swelling.
On a separate occasion, he was said to have attacked Ms Melendez while she was in a car before she got out and escaped to an off-licence.
The court heard that staff reported that she asked them not to contact police as she was afraid he would kill her.
The judge said: "Guess what, she turned out to be right".
The prosecution described it was a domestic violence case, involving gratuitous violence with extensive and multiple injuries on a vulnerable victim before her death.
It said the murder was the accumulation of cruel and violent behaviour over a period of time.
The judge said the only mitigating factors he could recognise were "some signs of remorse" as well as the "horrible childhood" that Scott had endured which led to addiction and mental health problems.
However, personal circumstances carry less weight in murder cases, he added.
The judge said that he did not regard the case as "anywhere near the borderline between murder and manslaughter".
Mr Justice O’Hara said that Ms Melendez was a "particularly vulnerable young woman", adding that Scott had acknowledged a disparity in their sizes.
"In addition to that, she was a drug addict who he beat up again and again and again until he killed her."
The judge said that while Scott had said he had suffered injuries, there was no evidence that he had been hurt by her hands to any degree of note.
The evidence, he said, showed that when the defendant attacked her, he inflicted extensive and multiple injuries on her before the final assault.
The judge accepted the murder was not premeditated but added that it was a foreseeable end result of how he had treated her.
"What on earth did he think might happen to her if he beat her up again and again and again and again?
"She begged the staff in the off-licence not to call the police because she was afraid he would kill her and that is exactly what he did."
'I had to start secondary school without my mum knowing' - son
Mr Justice O'Hara said that he had received "exceptionally moving" victim impact statements from Ms Melendez’s mother, two of her aunts, and one of her children.
Her mother, he said, found it impossible to put into words the "suffering the cruel murder has caused" and that her grandchildren had struggled to find peace.
Ms Melendez’s teenage son said that he was made fun of and bullied when his mother’s murder was reported.
"I will never know if my mum would have been able to get better and I could have spent more time with her.
"I had to start secondary school without my mum knowing, and I think of all the big things in my life she will miss out on.
"I just feel like my life will never be the same without her and every birthday I see as a constant reminder of her," he said.
Reading a pre-sentence report from the probation service, the judge said that Scott had expressed that Ms Menendez did not deserve what happened to her, adding: "I genuinely loved her to bits".
"I want forgiveness I need to do right by her. That’s why I pleaded guilty. I took her from her family and kids."
In arriving at the length of the sentence, Mr Justice O'Hara was asked to take note of delays in proceedings due to the "unusual" impact of the Covid-19 pandemic.
Scott was initially arrested on 26 March 2020 but was not interviewed until January 2022.
In the middle of that 22-month period, he was also in custody in relation to assault of police officers.
In effect, the court heard that Scott was in custody for the matters relating to Ms Melendez alone for approximately 12.5 months. but the exact time would be worked out at a later stage.
Announcing his decision, Mr Justice O'Hara put a provision that that period would be taken off the sentence - as there would be no administrative way for the prison service to declare that as a period of remand.
It was not open to the judge to implement consecutive sentences for the other offences to which Scott pleaded guilty, but he was able to use them as an aggravating factor in arriving at the final tariff.
He imposed a life sentence with a minimum tariff of 19 years before his release can be considered.
The judge said this would be reduced at a later date - to account for the time that Scott spent in custody in relation to the matters during the pandemic - when a final determination on the exact number of days had been made.
