Jung Yoo-jung, 23, killed and dismembered a teacher in Busan, South Korea. She posed as the mother of a 9-year-old girl to hire the teacher, with whom he stayed at home.

She dressed in a student uniform that she had bought online so that the teacher could open the door with confidence. She did not know that at that time the security cameras of the city of Busan were already following her steps and looking for her. They captured their journey with the suitcase in which he had taken a taxi to approach the Nakdong River.
