In fact, every unit has a backdoor that is not easy to detect, but in the past few days, Yuan Chen and others have focused on verifying the authenticity of Xiaoxiao's suicide, and no one has noticed this.
More importantly, there is no surveillance around this side door.
This means that as long as the murderer comes up from the side door and climbs 27 flights of stairs, he can arrive at the door of Xiaoxiao's house silently.
After solving this problem, Wang Yuzhi became suspicious again, because he could have escaped from the surveillance camera again through the stairs and entered the crime scene after leaving Xiaoxiao's house, and this time he had enough time to deal with the scene.
But Yuan Chen did not take the next step with Wang Yuzhi. He asked Hao Weida to go to the bank and the housing management bureau. The two of them were investigating another person, a suspect they had ignored before.
When Qin Mengke performed an autopsy on Xiaoxiao, he provided Yuan Chen with a detail. Not all of the wounds on Xiaoxiao's head were caused by himself. He found that one of the wounds was caused by a blunt instrument.
This shows that Xiaoxiao was beaten to death or knocked unconscious and hung from a water pipe to pretend to commit suicide.
At 3 o'clock in the afternoon, Hao Weida brought what Yuan Chen wanted. Yuan Chen did not take action against the main suspect in his heart. He asked Hao Weida to bring back a person - a relative of Yu Mei, who claimed to be Xiaoxiao's distant cousin.
My uncle’s 36-year-old man——Cheng Baoguo.
When he first met this person, Yuan Chen felt that he was very strange. He clearly had a strong northwest accent, but he always claimed to be a local resident. And he had been close to Yu Mei and might have coveted her wealth.
.However, he is not the murderer suspected by the police, but he is the key figure in this murder case.
Yuan Chen determined that the murderer of Xiaoxiao was her mother - Yu Mei.
The secret that the uncle told Yuan Chen before was that Wang Yuzhi actually rented in this community, but Xiaoxiao himself did not know that the uncle had also encountered Wang Yuzhi hanging out with other women in the unit he rented.
The surveillance on the night of the incident showed that Wang Yuzhi entered his rented unit at 10:32, and at 10:34, Wang Yuzhi returned to his rental house and never took the elevator downstairs again.
Cheng Baoguo told Yuan Chen that Yu Mei had stayed at his place that night, but at 8 o'clock, Yu Mei left.
Yu Mei used to be a nurse. Compared to Wang Yuzhi, she knew how to clean up the crime scene. More importantly, she was the only one who could quickly summon a large number of relatives to the scene after the incident and destroy it. Her mother's identity was unknown.
It was even more confusing. She had cried and fainted several times before Yuan Chen came. It was precisely because of this that Qin Mengke believed Yu Mei's performance and issued a certificate confirming suicide.
Yu Mei may have killed her daughter, even though this theory is hard to accept.
Compared with men, female suspects' psychological defenses are actually relatively fragile. In the interrogation room, she and Yuan Chen explained how they killed Xiaoxiao without much questioning.
As for the reason, Yu Mei just left this sentence:
"Those who are reluctant to part with their loved ones and enjoy the flesh are those who rebel against God and are targets of destruction."
Yu Mei personally destroyed her biological daughter.
Yu Mei said that she stayed in the bathroom for three hours, staring at her daughter hanging from the water pipe.
The results of Hao Weida's investigation showed that Yu Mei once sold the property under her name for more than 2 million yuan. She transferred the money to Cheng Baoguo and eventually transferred it to an overseas account.
At first glance, this may seem like a scam, but the truth is actually even more shocking.
After Old Tang's death, Yu Mei and Xiaoxiao's life trajectories changed completely, even though he was not a competent husband and father.
Without the constraints of Old Tang, Yu Mei, who has a net worth of millions, started a new life. In Old Tang's marriage, she did not feel the happiness of being a woman. Instead, she was more like an old mother who worked for the family. Old Tang's death did not
Without letting her feel too much sadness, she began to dress herself up and prepare for the beginning of a new relationship.
One month after her husband's death, Yu Mei met Cheng Baoguo. His sweet words seemed to give Yu Mei a second spring. She felt her long-lost happiness and wanted to be with Cheng Baoguo.
But Cheng Baoguo only wanted the money in Yu Mei's pocket, and besides, Cheng Baoguo was not just a simple liar.
Xiaoxiao learned about her mother's new relationship. Although she felt a little worried, she still didn't interfere too much. She just asked her mother to be careful not to be deceived.
After getting along with Cheng Baoguo for 3 months, one day he told Mei that he was an apprentice. Their school stipulated that only apprentices could intermarry. Without thinking, Yu Mei agreed to Cheng Baoguo's request and joined a group called -
—Organization of Southern Theology.
This Southern Theology is an out-and-out fraud group. Under the guise of the Doomsday Judgment, it requires apprentices to purify their six desires, cut off their worldly ties, and fulfill their duties, that is, to give up all selfish desires in the world and donate everything they have to their so-called master.
——"Female Saint".
Cheng Baoguo said that if you want to get married, you must memorize their so-called "Bible". As long as you pass the written examination within the church, you can get married. However, this so-called "Bible" is actually just a poorly printed booklet.
But Yu Mei regarded it as a treasure, and the book cover alone was covered in three layers. She held this book and talked about it every day like a student. Xiaoxiao, who was with her, didn't care at first, until one day she discovered that Yu Mei
The property in his name was sold.
In Mei's words, this is called "doing one's duty" for the saints.
She took away her mother's bank card and credit card, and only gave Yu Mei 3,000 yuan a month. She didn't care how she was criticized, she just didn't want her mother to get deeper into trouble. As for Cheng Baoguo, Xiaoxiao asked Wang Yuzhi to clean it up.
However, Cheng Baoguo proposed to break up with Yu Mei.
Yu Mei intercepted Wang Yuzhi and Xiaoxiao at the door of the security room, accusing them of ruining their hard-won relationship. There was a pushing and shoving between the three. Wang Yuzhi pushed Yu Mei, and Xiaoxiao began to protect her mother.
He kept hitting Wang Yuzhi with his bag.
Wang Yu always felt that he was wronged. He was helping his girlfriend with something, but in the end he failed, so he slapped Xiaoxiao. He thought that the mother and daughter were really stupid, and Yu Mei was ignorant. Xiaoxiao
It is foolishness and filial piety.
At first, Yu Mei did it for love, but after studying the teachings every day, she was completely brainwashed by this booklet. She felt that money was the dirtiest thing in the world and must be handed over to their "holy immortals" for safekeeping.
She began to promote Southern Theology to Xiaoxiao, hoping to use the money in Xiaoxiao's hand to "perform her duty", wash away her sins, and survive the doomsday judgment.
How could Xiaoxiao accept this fallacy?
In Xiaoxiao's consciousness, it was this pamphlet that made her mother look less like a human than a ghost. She wanted to find a way to wake up her mother. On the day of the incident, she hid the pamphlet while her mother was not paying attention.
and this became the trigger for Yu Mei’s stupid murder of her daughter.
