Police investigating a fire in Gapyeong, Gyeonggi Province, where three families are killed, are in trouble.

The only survivor and the youngest son who acted suspiciously on the day of the incident are in a difficult state of credible statements, and most of the clues are that it is difficult to determine the cause of the fire, and there is no CCTV nearby.

On the 23rd of last month, a fire broke out in a house in Gapyeong-eup, Gapyeong-gun, Gyeonggi-do, 1:13 AM.

In the house, Mr. A (82), Mrs. B (65), and son C (51) were found dead, while Mrs. B was in the bathroom and Mrs. A and C were hidden in the room, respectively.

However, since the youngest son D (46), who lives in the house, was not seen, the fire department mobilized a fork lane, etc., for about three hours to search for life.

Meanwhile, Mr. D appeared near the house at 5:40 a.m., 4 hours later, and it was Mr. D when the police randomly carried a man who giggled with a weapon.

Although Mr. D's arson suspected, Mr. D had severe symptoms of schizophrenia such as hallucinations, making it impossible to investigate the statement, and the police eventually admitted Mr. D to the hospital.

There is no CCTV in the vicinity of the house or within a few hundred meters of radius, and the behavior of Mr. D at the time of the fire is unknown.

The police explained that there is no clue so far, and it seems that it will take a long time to figure out the case.
