Han Ce's group stayed up all night in the police station, carefully searching for all kinds of information about Wei Wan, but they still couldn't find any clues.

At dawn, the medical examiner finally brought a complete autopsy report.

To everyone's surprise, Wei Wan turned out to be pregnant, and she was just pregnant, about six weeks or so.

Han Ce asked the forensic doctor, "When a woman is six weeks pregnant, her body should have already reacted, Wei Wan knows about her pregnancy, right?" ”

The forensic doctor nodded, "In the early stages of pregnancy, because of the large secretion of progesterone in the body, the body will have different degrees of early pregnancy reactions, such as poor appetite, fatigue, and easy nausea and vomiting, and the most important thing is that the menstrual period will be delayed all the time.

If the deceased Wei Wan had paid enough attention to her body, I believe she would have known about her pregnancy a long time ago. ”

Han Ce nodded, Wei Wan has a boyfriend, and it is normal for her to get pregnant.

But what is suspicious is that the autopsy report shows that there is strong sulfuric acid in Viwan's uterus, and there are tiny pinholes in her stomach. The medical examiner deduced that the killer used a syringe to inject strong sulfuric acid into Wei Wan's stomach into her uterus.

Because the amount of strong sulfuric acid is not very large, it is not visible from the surface of her belly, but her uterus is found to contain strong sulfuric acid by taking amniotic fluid.

In addition, Wei Wan's hands were wiped with alcohol by the murderer, so no useful clues were found on them.

The only useful clue now is that Viwan is pregnant, and that she was forcibly injected with strong sulfuric acid into her stomach before her death.

Han Ce looked at the autopsy report and analyzed, "The murderer injected strong sulfuric acid into Wei Wan's body, and the purpose was obviously to kill the fetus in Wei Wan's belly. Therefore, the child in Weiwan's belly is the only clue at present.

I think it's very likely that this is a love killing.

We must find out whether the child in Wei Wan's womb is her boyfriend Chen Hefan, and whether she has had an improper relationship with another man. ”

Shen Jikang also echoed, "Actually, I also think this is a love killing, the murderer's fundamental purpose is to kill the fetus in Wei Wan's womb, it is likely that Wei Wan was desperately struggling when the murderer was violent, and the murderer killed her in a fit of anger." ”

Xu Kunxi, who had been quiet, continued at this time, "I think the person who injected strong sulfuric acid into Wei Wan's stomach is a woman. ”

As soon as he said this, everyone looked at him.

Han Ce asked, "Why a woman?" ”

Xu Kunxi smiled contemptuously and said, "If a man wants to kill the child in Wei Wan's belly, why bother? Also injected with strong sulfuric acid? No, as soon as Wei Wan struggled, the strong sulfuric acid would be sprinkled on himself.

If a normal man wants to kill the child in a woman's belly, don't they all punch and kick the woman directly in the stomach until the woman bleeds. ”

Shen Jikang immediately raised an objection, "Xu Kunxi, just based on this, do you think the murderer is a woman?" Can you be a little more arbitrary in your investigation? Isn't there a man who likes to kill people in a more vicious and troublesome way? ”

Xu Kunxi shook his head, he looked at Shen Jikang and said, "Shen Jikang, you don't understand women. That person injected strong sulfuric acid into Wei Wan's belly, not just to make the fetus in Wei Wan's belly die.

Her real purpose is to destroy Wei Wan's womb so that she will never be able to have children in the future. ”

Hearing this, Zhou Zhuyu not only put forward the meaning of her cousin's opinion, "However, if the murderer wanted Wei Wan to die from the beginning, then why bother to inject her with strong sulfuric acid, anyway, it is impossible for a dead person to have a child." ”

Xu Kunxi looked at Zhou Zhuyu when he heard this, and then said, "That's the problem. I think there must have been two people at the scene of the crime besides Wei Wan, one was a woman who injected strong sulfuric acid into Wei Wan's stomach, and the other was a man who hit Wei Wan with a blunt object on the back of her head and drew a quadrilateral shape at the scene.

And this man is very likely to have feelings of admiration for Wei Wan. Hate because of love is the root cause of many love homicides. ”

Han Ce listened to Xu Kunxi's analysis and fell into deep thought, but Shen Jikang didn't agree with Xu Kunxi's point of view at all, he said directly, "Xu Kunxi, in addition to reasoning ability, evidence is also very important in investigating the case, what you say is one set at a time, you think this is writing detectives, just use your brain to talk nonsense?" What about the evidence, what about the evidence? ”

This time, without waiting for Xu Kunxi to refute himself, Han Ce had already agreed with Xu Kunxi's point of view first, he said, "Ji Kang, Xu Kunxi's analysis is reasonable.

Have you forgotten that there are only the fingerprints of Ruan Fu, Wei Wan and another person on the handle of the entrance door of Wei Wan's house, and it is obvious that the murderer deliberately left that fingerprint to mislead us.

He could be careful enough to wash Wei Wan's hands with alcohol, how could he miss the fingerprints on the doorknob? I guess that the set of fingerprints should belong to the woman who injected Wei Wan with strong sulfuric acid, and the murderer who killed Wei Wan only appeared after the woman left, and then killed Wei Wan. ”

Zhou Zhuyu was puzzled, "I don't understand, if the murderer only appeared at Wei Wan's house after the woman left, then how did he clean up all the other fingerprints on the doorknob, leaving only the fingerprints of the woman and Wei Wan?" He can't use human eyes to identify fingerprints, right? ”

Tao Lifan tried to analyze, "Could it be that the murderer didn't clean the fingerprints on the doorknob at all, and Wei Wan and the woman's fingerprints were originally printed on it?" After all, it was her own home, and she would have her fingerprints printed on it when she went in and out of the house. ”

As soon as Tao Lifan said this, Zhou Zhuyu gave him a blank look and said lightly, "Tao Lifan, are you a pig?" The report wrote that the doorknob of Wei Wan's house was very clean, and there were only three sets of fingerprints in total. There are only three sets of fingerprints, how can there be only three sets of fingerprints on the doorknob in ordinary people's homes, even if Wei Wan goes in and out by herself, she will print many sets of fingerprints.

And according to the information, during Wei Wan's filming abroad, no cleaning staff entered her house to clean it at all, so there is no possibility that the doorknob was cleaned by the cleaning staff. So it can only be the fingerprints cleaned up by the murderer. But it doesn't make sense, how did he do it? ”

Han Ce said affirmatively, "The murderer is definitely capable of doing it." He must have entered Wei Wan's house before Wei Wan went home, wiped the doorknob of her house clean, and then hid in the shadows. After the woman came in and injected sulfuric acid into Wei Wan, he came out to kill Wei Wan.

The murderer knew the woman who injected sulfuric acid into Wei Wan's body, and also knew that the woman would definitely go to Wei Wan on the day of the crime. ”
