The murder of a family sparked an inquiry into the matter.

The Raincoat Killer’s first episode depicts how authorities began to piece together the wider picture of a possible serial killer. Authorities were alerted to the brutal murder of a family when the grandfather returned from work. The evidence discovered at the crime site was related to a case that had been open for two weeks. Authorities were ignorant of the relationship, according to the docu-series, since jurisdictions kept to themselves.

On CCTV, the perpetrator was observed wearing the victim’s jacket at a fourth crime site. However, the leads turned cold as the authorities were preoccupied by a series of occurrences in the red-light district and the collapse of Korea’s economy. Yoo began to target sex workers as a consequence of a change in circumstances, and the case was closed.
