Lisa Borch was just 15 when she began trawling internet video site YouTube for videos of British aid workers David Haines and Alan Henning being murdered by ISIS fanatics.



Later she and her 29-year-old extremist boyfriend Bakhtiar Mohammed Abdulla launched the horrendous attack against her mother.

The pair had been planning to flee to Syria to join ISIS, a judge was told.



A court heard how the teenager became infatuated with with the terror group after falling in love with an unnamed Muslim.



He jilted her when he moved back to Sweden to be with his wife and children but she quickly found a new lover in Iraq-born Abdulla, who she met at a refugee centre near her home.



A court was told how the pair tried to cover their tracks immediately after the murder, which was carried out by them both.

As her mother lay dying Borch called police and told them: "I heard my mother scream and I looked out the window and saw a white man running away. Please come here, there is blood everywhere."



When officer arrived they found Mrs Holtegaard, whose husband was away on business, covered in her own blood in bed.



Detectives immediately became suspicious of the teenager because, rather than grieving, she was simply sat in the living room playing with her iPhone and watching videos on YouTube.



When they asked where her mother was, Borch refused to leave her computer and simply pointed upstairs.

A later police examination of the computer showed that she had watched endless repeats of the beheadings of the two Britons, both of whom had gone to Syria on humanitarian missions.



The court heard that the teenager had endlessly rowed with her mother, with the arguments becoming so bad that her twin sister decided to move out of the house.



Prosecutors told her trial that the pair had repeatedly clashed over her relationship with Abdulla, and it was this "endless rowing which cost the mother her life".



Her mother had wanted the teenager to leave the Islamist extremist, who was 13 years older than her, and "live the life of a normal teenager".



Borch claimed at the trial that she and Abdulla were "just good friends" but authorities said they were lovers.
