Police probe mishandling of murder case; father questioned, new corruption unit formed

South Korean police are intensifying their investigation into alleged mishandling of the case involving the murder of high school student Jang Yun-gi. The special investigation team questioned Jang's father, a police superintendent, for eight hours. Prosecutors also summoned the elder Jang for questioning the following day, an unusual step for both agencies to question the same individual consecutively. This move comes amid discussions about abolishing prosecutorial supplementary investigation rights, signaling a high-stakes effort between the two investigative bodies. The police, facing scrutiny over potential mishandling and internal collusion, announced the creation of a new 'Internal Corruption Investigation Unit.' Investigators reportedly focused on how evidence, including adult toys found in Jang's room, was disposed of and the nature of communication between the father and the investigative team. The father reportedly cooperated with the investigation without legal counsel and requested an extended late-night questioning session.
