Investigation Reveals the Truth Behind the Mysterious Woman and Hoai’s Death
The police were locked in a compound and the freezer was turned off by a woman who was thought to be looking for something and may have been sent by someone named Thoung. Later, it was found out that the woman was really Thoung, who had put on a wig to look like her sister.
She said that she found her sister Hoai dead in a closet, burned her body, and left clues to get away from her abusive husband, who had threatened to kill her if she tried to leave. Thoung said he didn’t kill Hoai, but he was put in jail for murder and mistreating a dead body.

Thoung says that Hoai’s boyfriend killed her because they always fought about other women, but the chief thinks that the boyfriend killed her by accident when they were fighting. The detective thinks that Hoai’s husband may have killed her because he thought she was Thoung when he saw her kissing another man.
