In June 2019, the late Yoon Sang-yeop, who was a researcher at a large corporation at the time, went to the Yongso Valley in Gapyeong, Gyeonggi-do with his wife and acquaintances, and suffered a bowel movement.



It was past eight o'clock in the evening when he dived into the valley and never got out of the water.



At that time, the police closed the internal investigation due to the death of the deceased, but five months later, the investigation began again with a report from a bereaved acquaintance.



Since then, several decisive suspicions have been raised on SBS 'I want to know'.



There were testimonies that the deceased could not swim at all, and

At the time of the accident, it was confirmed that one of the party members and Mrs. Yoon's wife were in an internal relationship.

It was also revealed that Yoon's wife claimed the death benefit of her husband, but the insurance company refused to pay it, saying it was suspected of committing a fraud.



The prosecution, which conducted a full re-investigation after the broadcast, revealed the identity of Yoon's wife, Lee Eun-hae, and her accomplice, Jo Hyeon-soo, on the 30th.



It was determined that those who disappeared immediately after the subpoena investigation in December last year murdered Yoon for 800 million won in death insurance.



As a result of the prosecution's investigation, it was additionally revealed that they had failed to kill the deceased twice in the past.



The prosecution also requested that if you know any clues about their whereabouts or whereabouts, they would like to report it.
