A private diver who took part in the search for victims of the sunken Sewol ferry has been found dead in his garden.
 
According to the police, the family of 43-year-old Kim Gwan-hong found him lying on the floor dead in the greenhouse garden that he ran in Goyang, Gyeonggi Province at around 7:25 a.m. Friday.
 
The police examined security camera footage inside the greenhouse and did not find any trace of an outside intrusion. Also with no injuries to the body, the police have likely ruled out foul play.
 
Earlier Kim is known to have sent a note hinting at a suicide to an acquaintance. 
 
The police suspect Kim may have taken his own life.
 
Officers will request an autopsy with the National Forensic Service to identify the exact cause of death.
