The boyfriend of a mysteriously dead woman, who went missing around the time of her death, was found hanged in a nondescript mountain in Namyangju, Gyeonggi Province on Sunday, deepening the riddle of the case.

The police presume the man, surnamed Kim, died about a month ago on July 25, which is the day he disappeared in the same clothes he was found dead in. No suicide note was found.

The Sujeong Police in Seongnam, Gyeonggi Province said that Kim, 60, had been the prime suspect behind the murder of a 63-year-old woman who was found in a decomposed state on July 29 at her apartment.

Reports of an unidentified stench led to the discovery of the women’s body. Based on the level of decay the police presumed she had been dead for at least four to five days.

The National Forensic Service was unable to determine the exact cause of her death despite an autopsy. There were no obvious signs of external struggle that pointed to a homicide.

Kim, the deceased women’s boyfriend who lived in the basement flat of the same apartment, could not be contacted after having been seen for the last time in the morning of July 25 taking a taxi from Seongnam to Namyangju.

Found about a month later on Sunday, Aug. 21, Kim was in the same blue t-shirt and the indigo pants he was described as having worn leaving his residence for the last time.

The police are investigating to determine whether Kim was responsible for his late-girlfriend’s death or if he was a distraught lover who resorted to extreme measures upon his beloved’s death.
