·52 min·3 clips

After the door closed, Young stabbed the tutor more than 110 times before dismembering the body.

1. Crimehub: A True Crime Podcast centers this episode on Jung Yoo-jung, a Busan tutoring-app murder involving a 26-year-old English tutor and a 23-year-old suspect. 2. The narration frames the case around Jung Yoo-jung, the unnamed tutor, and David Schmidt and Colton Scrivener, whose commentary matters to the episode's argument about true-crime fascination. 3. The episode asks whether Jung's claim that she killed out of curiosity explains the crime, or whether a deeper mix of resentment, isolation, and planning drove it. 4. On May 24, 2023, a university student received a tutoring-app message from a parent seeking English lessons for a third-year middle school student in Busan. 5. The tutor declined because the commute was long, but the parent begged for a trial lesson at the tutor's own apartment and won her over. 6. Two days later, on May 26, the tutor prepared worksheets and waited for the child who arrived at about 6 p.m. in a school uniform. 7. The episode states that the apparent middle school girl was actually 23-year-old Jung Yoo-jung, a stranger with no connection to the family. 8. Jung attacked after the front door closed, and the narration says the victim suffered more than 110 stab wounds, mostly to the chest and neck. 9. The story then follows Jung's cleanup: changing clothes, leaving on CCTV, buying trash bags and bleach, and returning to dismember the body. 10. A taxi driver later became crucial after Jung loaded a heavy black suitcase that appeared wet and red and asked to be taken near the Nakdong River. 11. The episode notes that police found the suitcase, then recovered a bloodied school uniform and the victim's ID, which linked Jung to the apartment and the riverbank. 12. Detectives also found three months of searches on Jung's phone about dismemberment, disposal, and how to get away with murder. 13. The narration cites a note translated as "if I don't kill her, this anger won't be relieved," which investigators treated as evidence of intent. 14. When first questioned, Jung gave shifting explanations, including claims that another person had killed the tutor and that the attack had been an accident. 15. The episode says court-appointed psychiatrists rejected a mental-illness defense, while prosecutors argued that her family conflict, online searches, and prior attempted lures showed deliberate preparation. 16. The prosecution described at least two earlier attempts to lure victims, including a teenage boy and a young woman, before she settled on the tutor-app approach. 17. Experts quoted in the episode argue that most true-crime listeners do not become violent, and that curiosity alone does not predict action. 18. The tone is investigative and narrative, with detailed chronology, courtroom reporting, and repeated use of direct factual claims to build the case. 19. Listeners interested in South Korean true-crime cases and forensic investigation. 20. Skip if you want a lighter, less graphic courtroom narrative.
