A Danish teen named Lisa Borch was sentenced to nine years in jail for stabbing her mother to death after binge watching hours of Isis beheading videos. The 15-year-old reportedly planned to join the radical terror group with her 29-year-old boyfriend, Bakhtiar Mohammed Abdulla, but her mother was trying to break them up.

After watching the beheading videos on repeat, Borch and Abdulla are said to have stabbed Tina Romer Holtegaard with a long kitchen knife. When police arrived, the teen reportedly didn’t interact with them and just pointed to the stairs leading to her mother’s bedroom.

Both Borch and Abdulla blamed one another for the murder during the trial, and they were both given heavy sentences. While the teen got nine years, Abdulla was sentenced to 13 years and he will be kicked out of Denmark afterwards.
