Although the three murder cases have been solved, there are still many doubts that have not been clarified.
First, what did Ye Qingwu go through in the three years since she disappeared?
Second, who was the person who helped Ye Qingwu go through the formalities for suspending school and also hid the truth from her family?
Third, how did Ye Qingwu obtain Song Huihui’s bone marrow, who helped her perform the bone marrow transplant, and why did she undergo plastic surgery?
Fourth, Ye Qingwu killed someone for revenge, but why did she leave a Y mark at the scene?
Fifth, was Ye Qingwu really responsible for the murder in the unfinished building? Or can she complete such a cruel killing method alone?
Sixth, where did Xu Tao and Xie Yao go? Have they been killed? Or are they also participants and have now absconded?
Seventh, was Ye Qingwu's death suicide or murder? If it was murder, why did Xu Mo kill her?
Eighth, is it really Ye Qingwu lying on the dissecting table at this moment? Could she be Song Huihui?
The last guess seems a bit unbelievable, but Medical Examiner Qin clearly stated this in the autopsy report.
There are three reasons.
First of all, after Luo Bin died, the police found Song Huihui's body, but her body had been carefully processed. They encountered a lot of problems when doing DNA comparisons. In the end, they determined that the other party was Song Huihui through bone marrow.
In the past, this conclusion would have been correct, but Song Huihui transplanted bone marrow to Ye Qingwu before her death.
In other words, Ye Qingwu and Song Huihui have the same DNA.
Secondly, Ye Qingwu got pregnant before she dropped out of school.
The police found the hospital where Ye Qingwu was examined and obtained the information report.
The report showed that Ye Qingwu was four months pregnant and had passed the time for abortion.
But during the autopsy, the forensic doctor found that Ye Qingwu had neither a history of pregnancy nor a history of childbirth.
The most important thing is that Luo Bin is sterile.
On this point, when the police investigated Luo Bin's case, his wife gave a clear answer. She had cheated on her and the child belonged to someone else, but Luo Bin didn't know it.
Of course, the police felt that Luo Bin knew.
Maybe his wife's cheating was one of the incentives that prompted him to commit the crime.
In addition, the forensic doctor did not find any fingerprints during the autopsy.
Ye Qingwu's fingerprints were artificially destroyed.
Moreover, when the police inspected the three scenes, no fingerprints were found, and even the murder weapon found did not have any fingerprints.
It was obvious that Ye Qingwu was fully prepared when she decided to take revenge.
With the emergence of this doubt, the investigation of the case reached a deadlock.
Of course, it is true that Ye Qingwu killed five Guo Zihao people, and there is no problem with this.
But the police must find out Ye Qingwu's true identity.
If she was Ye Qingwu, how did she get in touch with Song Huihui, who also disappeared and was eventually killed?
If she was Song Huihui, how did she escape from the devil's cave established by Luo Bin?
In other words, no matter whether it is Ye Qingwu or Song Huihui who is dead now, there is a mysterious person behind them.
But then came new problems.
If the mysterious person exists, what is his or her purpose?
What is the relationship between this person and Xu Mo?
Or could Xu Mo be this mysterious person?
If so, then Xu Mo would have the motive to kill Ye Qingwu or Song Huihui.
But is this possible?
While the police were busy investigating Ye Qingwu, the interrogation against Xu Mo also ended.
Xu Mo explained everything he had done these days and what happened on the rooftop of the school building.
Fang Mo fell into deep thought after hearing this.
Judging from Xu Mo's explanation, he indeed did nothing and Ye Qingwu committed suicide.
However, this statement is simply unconvincing.
The reason is also very simple.
Even if Ye Qingwu felt that her great revenge had been avenged, she no longer had the motivation to live, and wanted to die, but what was she doing to frame Xu Mo?
Would a person use her life to frame someone who has no grievances against her?
And based on Xu Mo's confession, Fang Mo also discovered other problems.
First, Xu Mo said that he decided to go to the roof of the teaching building because he received a note in the library, but the police did not find the note;
Second, before Ye Qingwu died, she asked Xu Mo to help her find Xu Tao and Xie Yao. She didn't look like someone seeking death, but she died anyway.
Third, the two words Ye Qingwu said before she died were obviously telling Xu Mo that someone had been watching him, but who was this? What is his purpose for doing this? There is no way to prove whether this person even exists.
Is it reasonable for a person who had no suicidal thoughts to commit suicide?
It's obviously unreasonable.
In addition, the police also investigated another incident.
Song Jiajia is missing.
Just a few days ago, someone claiming to be Song Jiajia's family member came to go through the discharge procedures.
According to hospital surveillance, this person was none other than Ye Qingwu.
"Could this be Xu Mo's motive for killing Ye Qingwu?" An Xin couldn't help but ask.
When Fang Mo heard this, he shook his head and said, "No."
"Why?" An Xin asked confused.
Fang Mo did not answer the question directly, but asked: "What do you think of Xu Mo?"
An Xin thought for a while and said: "He comes from a good family, is handsome, has a high IQ, has strong thinking, clear logic, and is very calm in situations..."
Before An Xin could continue, Fang Mo interrupted: "Since you said it, Xu Mo has a high IQ and is calm and collected in situations. Do you think he will kill someone impulsively?"
An Xin retorted: "Human beings have weaknesses and can be impulsive. It is not uncommon for people with high IQs to commit crimes and kill people on impulse."
Fang Mo nodded and said, "You are right, there are indeed such examples, but have you ever had contact with Xu Mo, do you think he is such a person?"
An Xin was silent.
Fang Mo continued: "In the past, Xu Mo might have acted impulsively because of Song Jiajia, but now he has lost his memory. No matter how good his relationship with Song Jiajia was before, Song Jiajia is now a stranger to him. "
"And you should have understood the situation at the hospital. Since the 404 case was solved, Xu Mo left the police station and has only been to the hospital once. Do you think this is a sign of a good friend?"
"Even if Xu Mo knew that Song Jiajia was taken away and hidden by Ye Qingwu, wouldn't the most important thing he should do be to capture Ye Qingwu and ask where Song Jiajia was hidden? Why did he kill someone?"
An Xin thought for a moment and said, "Could it be that when he was trying to subdue Ye Qingwu, an accident happened and he accidentally pushed Ye Qingwu downstairs?"
"I don't rule out this possibility, but you may not know that Xu Mo has practiced. Although it is not without professional training, it is more than enough to deal with ordinary people."
"ah!?"
An Xin was shocked and immediately asked: "So, Ye Qingwu committed suicide and Xu Mo was wronged?"
Fang Mo shook his head and said nothing.
An Xin was completely confused now.
