Teen kills mother with kitchen knife after watching ISIS beheading video of British hostages

Copenhagen: In a horrific incident, a 15-yr-old Danish teenager, Lisa Borch, brutally murdered her mother with a kitchen knife at their home in rural Kvissel after watching sickening ISIS beheading videos of British hostages Alan Henning and David Haines.

Lisa stabbed her mother Tina Römer Holtegaard over 20 times along with her 29-yr-old boyfriend Bakhtiar Mohammed Abdulla, according to a news report in The Daily Mail.

She had reportedly planned to flee to Syria after the murder along with Abdullah and fight for ISIS.

The teen has been sent to jail for nine years by court for the murder committed in October last year. Abdullah received 13 years prison sentence and will be expelled from Denmark once his sentence is complete.

During the court hearing, it was reportedly revealed that Lisa was in love with an unnamed Muslim man, who later moved away to Sweden, before meeting Abdullah.

After committing the murder, Lisa made a frantic call to the police but was found watching YouTube videos on her computer and playing with her iPhone.

When asked about her mother, she refused to leave her computer and simply pointed upstairs directing the police to her mother's bedroom.
