This 23 year old was such a true crime fan that she wanted to try out a murder for herself, and so she killed a stranger out of curiosity. Jung Yu jung from South Korea was obsessed with true crime shows, police said. Prosecutors says she used an online tutoring app to find a target, contacting more than 50 home tutors about English lessons. She turned up at the 26 year old victim's door wearing a school uniform that she bought online, prosecutors said. Once inside, Zhang stabbed the teacher more than a hundred times. She dismembed the body and took a taxi to leave some of the remains in a remote parkland. She was arrested after the taxi driver tipped off the police about a customer who had dumped a blood soaked suitcase in the woods, police said. Jung's online browsing history shows she had researched for months on how to get rid of her body and how to kill, but police called her efforts careless as she didn't avoid CCTV. She's been given a life sentence.
