A victim impact statement from Angela Wrightson's mother, Maureen, was summarised by the judge.

Mr Justice Globe told the girls: "She describes the horror of seeing Angie's battered body in the mortuary. 

"She does not think she will ever be able to blink those images away. Having seen photographs of what Angie looked like at that time, I readily understand why she is of that view.

"She cannot understand how you could have been as violent as you were. She is not alone in that view. 

"She had been disgusted by the laughing and giggling and sharing of photographs during the time of and immediately after the attack."

The judge refused to lift an order banning the identification of the two girls after hearing details of how the older one had repeatedly tried to kill herself. 

Mr Justice Globe said some of these attempts happened on court premises during the trial. 

In one, the judge told the girl that a court official "I am satisfied, saved your life". 

He said the case for naming the younger girl was stronger but he accepted she was also vulnerable. 

The judge told the older girl: "I am concerned and disturbed by what I regard as a heightened real risk that identification by a press blitz will elevate the risk to your life to such an extent that I am satisfied that there is a real and immediate risk to your life if you were to be identified as one of the two girls who murdered Angela Wrightson."

The two girls were sentenced to 15 years due to the suffering they inflicted on Angela Wrightson, the judge said.

Mr Justice Globe told them: "This was a sustained attack over a long period of time carried out with weapons in many different ways. 

"She [Angela] undoubtedly suffered considerably, both mentally and physically, before she ultimately lost consciousness and died."

The jury in the trial of the two girls who murdered Angela Wrightson was given a chilling insight into their behaviour.

The court was shown a picture drawn by the older defendant two weeks before Ms Wrightson was killed which depicts a female figure stabbing another person.

The girl said she drew it when she was "really really angry" and that she had been advised by her carers to use drawing as a way to manage her feelings.

The court heard it had been "a successful strategy" on previous occasions.

But today the pair of them were sentenced to a minimum of 15 years.

It is a rather antiquated term that the girls have been sentenced to 15 years at Her Majesty's Pleasure.

Children are sentenced in a very different way to adults. 

For these two girls, the judge has taken the starting point of 12 years and he has increased that to 15 years.

They cannot be released before those 15 years are up, unless they appeal to the Court of Appeal.

So will they be released after 15 years?

Not necessarily if they still pose a risk to the public.

"One life has been lost and several others have been ruined."

This was the message from one of the girl's defence barristers, as he told the court the girls "thought as children" when they battered Angela Wrightson to death.

In a five-hour attack, they used several items to kill her. Instead of calling an ambulance, they took a selfie with her.

By the time they finished, it was 04:00 and they dialled 999 and asked for police to take them back to their care homes.   

The two girls jailed for life for murdering Angela Wrightson showed no reaction as they were sentenced to 15 years each at Leeds Crown Court. 

Sobs could be heard from the public gallery as the sentence was read out by Mr Justice Globe.

Now both 15, the girls were 13 and 14 when they attacked Ms Wrightson in the lounge of her home in Hartlepool, County Durham.

They used weapons including a shovel, a TV, a coffee table and a stick studded with screws.

Two girls found guilty of murdering Angela Wrightson in her Hartlepool home have been sentenced to life with a minimum of 15 years.

The girls, then aged 13 and 14, inflicted over 100 injuries on Ms Wrightson in an attack in December 2014 that lasted more than five hours.

They used a variety of weapons, including a wooden stick laced with screws, a television set, a shovel, ornaments, a picture frame and a kettle.  

The judge has ruled that the two girls convicted of murdering Angela Wrightson will not be identified, despite applications by some media for their anonymity to be lifted.

The application was opposed by police and Hartlepool council.

The two schoolgirls committed a "cowardly" attack on Angela Wrightson, the judge says.  

"Angela's alcoholic state may have numbed some pain but it won't have taken it away completely," Mr Justice Globe said.

He added the attack included "gratuitous degradation" of the 39-year-old.

The two girls who murdered Angela Wrightson are looking at the floor as the judge sentences them. 

Chewing on their fingers as they listen to Mr Justice Globe, they are told they use 14 different items used to strike heavy blows on the vulnerable alcoholic.

The two girls who murdered Angela Wrightson took advantage of her hospitality to commit their murderous attack, the judge has said.

Mr Justice Globe said Ms Wrightson was an "alcoholic who didn't eat properly", adding: "Neighbours said she was kind, house proud and lonely. She'd invite anyone in for company - there lay her downfall.

"Children such as you would take advantage of her. Nobody expected her to come to any harm still less in the manner she was attacked by you."

Below is an artist's impression of Mr Justice Globe who is about to sentence the two teenage girls convicted of murdering Angela Wrightson:

Due to the age and vulnerability of the girls, he's not wearing a wig.

Angela Wrightson's family paid tribute to her after the two girls were convicted of her murder.

They said in a statement: "It's true that Angela (or Angie as she was known to us all) led a troubled and at times chaotic lifestyle. 

"And as a family we were not as close as we ought to have been. The chance to put that right has been taken away from us."

It went on to say: "The two girls responsible will one day be women themselves, free to live their lives and perhaps have children of their own. A right which was taken from Angie."

This CCTV image shows two schoolgirl murderers walking back to Angela Wrightson's house after attacking her in December 2014.

They had left the house in Hartlepool for "time out" at about 23:00, during which time they went to see a friend, who asked them why they were covered in blood.

They told him they had both fallen over and began listening to rap music. 

The pair, who were convicted on Tuesday, are seen above at 02:00 going back to the Stephen Street property. They stayed for a further two hours before calling the police to take them home.

The two girls convicted of murdering Angela Wrightson in Hartlepool had tried to shift blame on to each other during their trial.

The older girl accepted she struck the 39-year-old but said she did not intend her serious harm and accused her accomplice, telling the jury her younger friend told her to carry out the attack.

But the younger of the two said she played no part in the assault and did not encourage her friend in any way.

She told police her friend became angry and launched the attack after Miss Wrightson made a comment about her family.
