Lisa Borch, 15, has been convicted of murdering her mother, Tina Romer Holtegaard, who reportedly disapproved of her daughter’s 29-year-old Muslim boyfriend, Bakhtiar Mohammed Abdulla.

Borch stabbed her mother at least 20 times along with her Islamic extremist boyfriend whom she met in a refugee camp near her home.

After committing the murder, Lisa made a frantic call to the police.

She lied to police telling them: “I heard my mother scream and I looked out the window and saw a white man running away”.

Her mother’s husband was away on a business trip at the time, and when police arrived they found Holtegaard covered in blood.

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

In court Borch and Abdulla blamed each other for the murder but both got sentenced. He was sentenced to 13 years.

She got nine years, the first of which will be spent in a young offenders institution and the rest eight years will be in jail.
