A DANISH TEENAGER who killed her mother after watching Isis beheading videos will serve nine years in prison after a court threw her appeal out yesterday.

Lisa Borch, then 15, and her 29-year-old friend Bakhtiar Mohammed Abdullah were convicted last September of killing Tina Romer Holtegaard in her sleep by repeated stabs to the chest.

“She has said herself that she sometimes watches Islamic State videos,” prosecutor Karina Skou told AFP at the time.

After her mother went to bed, the girl claimed to have been watching TV and admitted to having watched “something with IS” on her mother’s iPad.

Asked if the video clips had included IS beheadings, she said she couldn’t remember.

The events took place in October 2014 in the northern village of Kvissel.

Borch was sentenced to nine years and Abdullah 13, followed by deportation to Iraq.

An appeals panel in Denmark did not accept Borch’s new account that she was “scared of Bakhtiar” and upheld the sentence, reportedly the longest-ever handed to a teenager in Denmark.

Lisa’s stepfather told Ekstra Bladet that they had sought psychiatric help and that her radicalisation would have happened in any environment.

“Her radicalisation is something going on in her head.

“She might as well have been attracted by bikers or any other extreme. But I fear that Lisa in a prison environment will be very easy to radicalise.”
