On the day of the crime, Mr. A broke into the house using a password secretly obtained from a past family gathering while Mr. B was taking his child to kindergarten. Afterwards, he overpowered Mr. B, who returned home, and attempted to sexually assault him while covering his face with a blanket. When the victim recognized his identity by shouting “”brother-in-law””, he killed Mr. B.
After committing the crime, Mr. A disguised the body of Mr. B as if he had accidentally slipped and died in the bathroom. After changing into the clothes he had prepared, he went home, cooked ramen, ate porn, and watched pornography. A few days later, he visited Mr. B’s funeral and appeared to be taking care of the children among the bereaved family.
