According to Daily Mail,Lisa Borch was aged only 15 when in October last year she spent hours on YouTube watching footage of the savage decapitations of David Haines and Alan Henning.
Afterwards she and her radical Muslim boyfriend Bakhtiar Mohammed Abdulla, 29, took a long-bladed kitchen knife and stabbed her mother Tina Römer Holtegaard at least 20 times at the home they shared in rural Kvissel.A court which sentenced Borch to nine years in jail heard how she became obsessed with militant Islam after falling in love with an unnamed Muslim man. But he jilted her when he moved back to Sweden to be with his wife and children.
Nevertheless she found a new soulmate in Iraq-born Abdulla, whom she befriended after meeting at a refugee centre near her home.
Following the brutal murder, in which both Borch and Abdulla participated, the teenager called police claiming:
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
Borch's twin sister had recently moved out of the family home because she couldn't stand the constant arguing that went on between her mother and sister.
The court was told that Borch had teamed up with Abdulla after being dumped by her first lover. The two planned to flee together to Syria and fight for the ISIS cause.
The rows with her mother intensified as she pressured her daughter to break off her relationship with him and 'live the life of a normal teenager.'
Prosecutor Karina Skou told the court that the pair made a diabolical pact to kill her mother saying: 'This murder was cold blooded, ice cold and committed in a bestial manner.'
