"The rest is my speculation, but I am now a forensic doctor, and speculation without scientific evidence is a forensic taboo.

Chen Tianyu said with a smile: "I asked you to come non-stop, what I want to hear is your speculation, you have been bound by rules and regulations over the years, and your thinking is obviously not as active as before." ”

Xu Jingnan scratched his head embarrassedly: "There is more contact with Western forensic technology, people are indeed easy to be rigid, plus we have strict discipline, forensic doctors are not allowed to participate in criminal investigations, and over time, my head will be a little dull." ”

Wan Yongkun said with a smile on the side: "Why don't you come out and run the rivers and lakes with us, and now that you have learned the craft, why are you staying inside?"

Xu Jingnan smiled bitterly: "Is it so easy to come up with it......?" If I really joined Beiting, I might not even be able to touch the corpse in the first place. He was telling the truth.

Wan Yongkun said disappreciatively: "At most, we will go out of the scene first, they are so slow." ”

Chen Tianyu hurriedly stopped their idle talk: "Forensic science pays attention to everything that speaks with evidence, does not represent any position, and can neither favor the suspect nor the victim." Jing Nan, your insistence is right, without a rigorous attitude, you can't do forensic medicine at all, now the times are different, and our concepts should also keep pace with the times. ”

"Okay, let's talk about your speculation? He pulled back to the point.

Xu Jingnan nodded: "From the analysis of the survey situation, I tried to carry out a rough on-site reconstruction. At that time, there should have been at least two people in the house, one of them was Hu Wenyi, and the other should have been a woman. Although there were not many traces of women at the scene, the fingerprints I took from a wine glass showed that there was a high probability that the suspect was a woman. ”

The woman met with Hu Wenyi temporarily, and brought red wine and takeaways on a special trip, most likely to catch up with the past. The two were eating and chatting, Hu Wenyi suddenly felt unwell, so he went to the master bedroom to rest, and died of poisoning soon after. The woman cleaned the whole room, took away the takeaway packaging and red wine, and left unhurriedly. ”

"The whole crime was very peaceful, there were no physical altercations and no fights. ”

Chen Tianyu said thoughtfully: "When I first came to room 1802, I found that the door was not locked, which means that this woman actually did not have the door key, and the way she entered the room was the door opened by Hu Wenyi, and this woman should be more familiar with Hu Wenyi." ”

Kuang Suo couldn't help but interject: "If this is the case, this woman's psychological quality is really too strong, killing someone is so frivolous and unhurried." ”

Wan Yongkun said strangely: "Isn't this murder case very simple? The suspect's fingerprints are left on the wine glass, as long as we follow the vine and cooperate with other supporting evidence, the police will soon be able to lock her identity." ”

"Well, that's exactly where the problem lies. Xu Jingnan suddenly changed his words.

He continued: "Cases that are too complex or too simplistic often have the potential to be artificially covered up. Think about it, if the suspect can think of cleaning the room and taking away foreign objects, why not take the wine glass with fingerprints with it by the way?...... As I said earlier, this woman is either a repeat offender or has a strong sense of anti-reconnaissance, and the chances of making common-sense mistakes are very small. ”

Wan Yongkun said disappreciatively: "Are you thinking too complicated, maybe this woman knows a little bit about the basic modus operandi, but not everything is so carefully considered, or she has a temporary emergency, and she didn't expect to miss a wine glass, after all, there can be no absolutely perfect crime in the world." ”

Xu Jingnan didn't mean to refute, but said approvingly: "That's right, this possibility also exists. ”

Chen Tianyu shook his head and recalled, "I remember that on the bedside table in the master bedroom, there was a bottle of sleeping pills?"

"There was indeed an empty jar of sleeping pills, and the lid was open. ”

"You also said that the poisoning was not consistent with an overdose of sleeping pills. ”

"Yes. Xu Jingnan is very sure of the authenticity.

Chen Tianyu sighed: "In other words, the suspect really wants others to mistakenly think that Hu Wenyi committed suicide?"

"Now it seems that the possibility of suicide can be basically ruled out. ”

Chen Tianyu showed a strange smile on his face, and he said calmly: "Undoubtedly, this is a well-planned murder, methodical and calm, but the method is very clumsy, and it accidentally left obvious fingerprint traces, right?"

"Uh......" Xu Jingnan wanted to say but stopped.

Chen Tianyu gave him an encouraging look, indicating that he had something to say.

In fact, this situation is rare, but if you put aside the physical evidence and simply reason, it is easy to fall into the strange circle of logic, which is contrary to the spirit of science. What if the case is really simple?......" Xu Jingnan hesitated.

Chen Tianyu said with a smile: "We are not solving the case now, it is the business of the criminal police, even if the analysis is wrong, it is not harmful, I know that your forensic doctors do not advocate excessive reasoning, so it is better to play a game." ”

"Uh, the game?" Xu Jingnan was stunned for a moment.

But he soon realized: "I get it." Well, I said that there is another possibility, and you can also help me analyze it...... If the murderer is a person who is proficient in criminal skills, then he will certainly not make a common-sense mistake, and the only explanation is to spread suspicion and confuse auditions. ”

"The killer left the wine glasses and two pieces of women's underwear in the wardrobe in the master bedroom, all planned in advance, because the man knew what to keep and what to remove. So the problem arises - it is very likely that the fingerprints on the wine glass are not the murderer's at all, and all the things that the murderer really used have been removed, and the situation we see now is all disguised. ”

"So, there were probably three people in the room at that time, not two. ”

Wan Yongkun was surprised: "Who will this third person be?...... Oh no, who is this second person? I'm a little confused. You're saying that there are two murderers, which is also unreasonable, if one is exposed, can the other still escape?"

Xu Jingnan hurriedly corrected: "My expression may have made a mistake, I should say so." I speculate that there were indeed only two people in the room at the time, but there were traces of a third person. And the traces of the third person were deliberately used by the suspect to confuse the public. ”

Although Wan Yongkun understood, he still scratched his head and said, "Oops, it makes me uncomfortable." Just say that the murderer brought someone else's cup and it's over!"

Kuang Suo said sarcastically: "You are a big old man, you have to join in the fun, really." ”

Everyone laughed, and the facts of the case have gradually become clear and clear after such a collision of ideas.

Xu Jingnan suddenly said: "Brother Kun, it's not that I deliberately want to go around, but after everyone's discussion, I think if someone really sets up a situation from it, then I'm afraid there are countless possibilities......"

Wan Yongkun was surprised: "What do you mean?"

Kuang Suo interjected: "Of course, Jing Nan means that maybe there was really a third person present at that time, or maybe a fourth person was present, since the traces have been erased, these are not easy to judge." ”

Wan Yongkun suddenly said casually: "According to what you say, the murderer can't be ruled out as a man?"

The speaker is unintentional, the listener is intentional, Chen Tianyu's mind unexpectedly floated the shadow of a person, although this person is unlikely to be a murderer, but he is a master of layout.

Since He Xiaoxue took the initiative to provide the key to the police, why did she hide the fact that she had already moved out? Regardless of whether she had this common sense or not, just looking at her frightened appearance, it was obviously not pretending.

From the beginning, he was a little suspicious of He Xiaoxue's real motive for going to Dynasty Pictures, at first glance there seemed to be no flaws, but after careful consideration, he felt that something was wrong. A person who has already decided to commit suicide by throwing himself into a lake will be moved by a fake marriage certificate?

......

Unless, this is not He Xiaoxue's residence at all, and her key confession was also pointed out by a certain "expert in the industry"! And there are almost only a handful of people who can lead the police and Beiting's nose.

So, who else will there be besides the Condor?

Is this person on the safe side, or is he playing with fire?
