Both private detectives and female staff were killed by Xie!
Reason:
17 years ago, Xie killed a prostitute by mistake, and his mother was a witness. Xie's father, Xie, kidnapped Xin to protect his son and threatened Mrs. Tang to testify that Lou was the murderer. In this way, Lou Shi Wen was sentenced and later died in an accident. . .
17 years later, Mrs. Tang asked a private detective to find out who threatened her in the past and found out that it was her family's legal adviser. Later, when Xie knew about it, he told his son to leave as soon as possible, but Xie didn't want his father to be ruined and decided to stay. . .
On the day of Mrs. Tang's funeral, Xie lurked in the Tang family, killed a private detective, and then killed a woman to cover her mouth. . .
