Lisa Borch, a 16-year-old from Denmark, was jailed for murdering her mother after watching videos of beheadings last year.
Borch, aged 15 at the time, was convinced by her 29-year-old Iraqi boyfriend, Bakhtiar Mohammed Abdullah, to stab her mother 20 times while she slept. The couple met at a refugee center.
Borch had plans to travel to Syria and fight alongside ISIS after she had become fascinated by beheading videos online. She had been introduced to them by Abdullah when the couple started dating.
The stabbing took place in October 2014, and reports say that Borch herself called the police afterward. When authorities arrived, she simply pointed to where her mother was, without looking up from her phone screen. It was later revealed that she was watching beheading videos at the time.
