Police investigate officer father over alleged evidence tampering in son's murder case

Police are investigating claims that the father of convicted murderer Jang Yoon-gi, who is himself a police officer, destroyed evidence related to his son's crimes. The investigation focuses on suspicions that Jang's father disposed of items crucial to understanding the motive behind the murder of a high school student.

Specifically, authorities are examining the disappearance of the car's black box memory card, which was reportedly used to analyze Jang's intentions. Additionally, adult dolls found in Jang's home were not presented as evidence, raising further questions. The suspect's father is also under scrutiny for allegedly burning three mobile phones, one of which belonged to Jang, shortly after the crime.

Jang reportedly discarded his primary mobile phone in a river the day before the murder. He then used a previous phone to track the location of a Vietnamese woman, according to reports. His father, who has been on leave since the incident, is currently the subject of the internal police investigation.
