Four children, including two young children, were found dead in a farm road car in Siheung City, Daejeon, on the 5th day of the children's birthday.
A carmaker official reported to the police that four A's (34), his wife (35), his son (4) and his daughter (2) were killed in a rental car built on a farm road in Siheung City at 4:15 am.
The official said that when the car, which was scheduled to return at 0:30 this morning, did not come back, went tracking the GPS and picked up the car and found that his family had been killed.
Police are investigating the situation with the possibility that Mr. A might have made an extreme choice because of the fact that the car door was closed and there were no signs of outside intrusion. A suicide note is not found, but he is investigating the incident and its connection according to the survivor's statement that he has suffered from debt.
