After Forensic Doctor Liu said this, Tang Hongye and none of them said a word, quietly waiting for Forensic Doctor Liu to continue to help them uncover the mystery, there were so many big rats at the scene of the crime, this must not be a coincidence, as for the intention of these rats to exist at the scene, except for the murderer, now I am afraid that only Forensic Doctor Liu can best guess it.

"I just conducted a preliminary examination of the corpse, the deceased is a male, the age should be around 30 years old, there are indeed no fatal injuries on the body surface, not even serious external injuries," Forensic Doctor Liu continued, "I said just now, some of the wounds on the deceased's body should have been bitten by rats before his death, according to the environment and temperature of this warehouse, as well as the degree of decay of the corpse, it can be preliminarily determined that the time of death is three to four days ago, and the corpse has not yet appeared Corrupt Giant, if it is found a day or two later, it may appear." If it is said that he died three or four days ago, then the mortis caused by death should have been partially alleviated, but it is worth noting that the torso of the deceased is twisted into an arch, forming a reflexion of the angular arch, head back, trismus, these are very consistent with the symptoms of Clostridium tetani infection, tetanus infection usually takes about a week to onset, but there are also some relatively fast 24 hours may attack, generally the shorter the incubation period, the worse the prognosis. ”

"So it's possible that the deceased was bitten by a rat, so he was infected with tetanus, and the attack was more urgent, so he died?" Tang Hongye felt a little incredible, "That'...... What ...... nature of the case?"

He didn't know what to say, although it was strange that there was such a large group of fat and big rats in the small warehouse, but when he came to the scene, his colleagues from the county bureau also said that the door of the small warehouse was locked from the inside, and the window was sealed from the outside, and everyone knew that the door locked from the inside could naturally be opened from the inside. After all, a tetanus attack is different from being highly toxic in the body, it is impossible to die within a few minutes, there is always a process of discomfort, from mild to severe, why did the deceased not choose to open the door and go out for help in this process?

It can't be suicide, right? Although the way to commit suicide does not necessarily have to be to hang yourself and jump off a building, it is obviously unreasonable to lock yourself up with a group of rats and let the rats bite you and then contract tetanus and die, after all, although there is a risk of tetanus infection from a rat bite, it may not be 100%.

No matter how you think about it, it feels unreasonable, and the expression on Tang Hongye's face is a little more confused.

Du Juan didn't say much in this process, except for the first sentence of asking Forensic Doctor Liu, he had been listening to Forensic Doctor Liu's introduction on the side, while looking here and there, and now he heard Tang Hongye's slightly confused question, so he raised his head, hesitated slightly, and said to Tang Hongye and the others: "It should still be killed by him, I think someone used other methods to make the deceased unable to open the door lock from the inside and rush out, so the door is locked from the inside, which is just a smoke bomb." ”

"Oh? How so? Fang Yuan listened to Du Juan's words, felt a little curious, and hurriedly asked, before Du Juan turned around, Fang Yuan had heard a lot about her in private, and the most impressive thing was two points, the first was of course her relationship as a "childhood sweetheart" who made Tang Hongye talk about it, and the second was Du Juan's work ability and comprehensive quality, Team Yang has always been praised, saying that Du Juan was also a very outstanding young criminal policeman in the original unit, and this time he took the initiative to ask for a transfer, which can be regarded as a general.

Now that this senior general had already opened his mouth, Fang Yuan naturally planned to listen to it.

"This house is quite old, when I came in just now, the paint on the big iron gate in the yard fell off piece by piece, and there was a lot of rust, and there was a lot of dirt in the yard, it can be seen that not only the house is relatively old, and it is usually neglected, but you look at the copper handle on the door of this small warehouse."

She reached out and carefully pointed to the side of the door that was open.

The door of this small warehouse is a lacquered iron plate door, and two copper handles are installed on the inside and outside of the door, the inner one does not look shiny, it is dark, but the outer one is different, although it is still old, it is much brighter overall.

"The one outside has been wiped!" Tang Hongye saw at a glance what the gap between the two was.

Cuckoo nodded: "It stands to reason that this doorknob on the outside should be exposed to more wind and rain than the one inside, so it should also be dirtier and older, but now it seems to have the opposite effect, if someone simply wants to wipe off the fingerprint traces, they don't need to use so much force, just wipe it gently." My guess may be a bit bold, and it may not be right, I think maybe someone heated the doorknob outside with a fire or something, because the door itself is a metal with good thermal conductivity, and the corresponding copper handles on both sides also have very good thermal conductivity. ”

"I don't agree with you." Before the others could make a sound, Tang Hongye was the first to frown and express a different opinion, "Such a big iron door, there is paint on it, and now the paint surface has no traces of being burned by fire, and the door lock is also good, so according to your kind of statement, it is unlikely to be established at all, but the doorknob is heated, and it will not affect the people inside to open the lock!" It's a big deal not to touch the handle! ”

The cuckoo didn't seem surprised by his refutation of himself, but as if it was expected, he patiently explained to him: "You're right, the whole door must not have been burned by fire, and there is no problem with the door lock, if you don't touch the doorknob, you can also unlock it, but the kind you said can only be achieved when the other party is very calm and calm, combined with the situation we see now, there are so many big rats in such a small warehouse, which is obviously unreasonable, The deceased probably wouldn't have known that there were so many big rats inside, and even took the initiative to lock himself up with the rats, causing himself to be bitten. So I think the deceased must have voluntarily hid in this small warehouse for some reason that we don't know yet, locked the door, and the rat was put in later. ”

"These rats made the deceased panic, maybe he was bitten in the panic, and then he wanted to open the door and escape, at this time we all have an instinctive action," the cuckoo stretched out his hand and made a pretending to open the door, "There is a handle on the door, we will instinctively pull the handrail with one hand, and the other hand to open the lock, so as to push the door and go out at the first time when the lock is opened, but at this time the doorknob is hot, and the hand is burned as soon as I grab it, just like I said, The door and door lock are all metal, and they are also thermally conductive, even if they are not directly burned, they will be heated to a certain extent because the doorknob is burned, and they happen to be in a very panicked situation, it is easy for the deceased to mistakenly think that the whole door is hot, and at the same time, the deceased is being attacked by a group of rats, so he gives up the idea of opening the door and escaping. ”

"It's a bold idea, but it's also a bit interesting." Forensic Doctor Liu was very interested in listening to the new young policewoman finish her thoughts, and also had the idea of opening the deceased's hand clenched into a fist to take a look, which could be regarded as helping to confirm whether the other party's bold hypothesis could be valid.

"And then? If, as you say, the suspect who was putting rats and burning doorknobs outside the door, what was the purpose? Let a swarm of rats bite the dead to death and eat them? Tang Hongye still feels that Du Juan's speculation has many unreasonable points, and it can't really be established.

Cuckoo shook his head: "I can't say this either, maybe that suspect really plans to do this, after all, not every criminal's actions can be explained by common sense, isn't it?" ”

Regardless of whether her speculation is reliable enough, at least this statement is something that Tang Hongye can't refute, Tang Hongye pursed his lips, and seemed to be a little unhappy about the fact that he couldn't refute, but he could only choose not to say anything, and turned his eyes to Forensic Doctor Liu, waiting to see Forensic Liu's examination results.

On the other side, after listening to Du Juan's analysis and speculation, Dai Xu also walked to the small window of the small warehouse, picked up the wooden board that he had just dismantled in a hurry, and carefully checked something.

"I think what the cuckoo said may be true," he quickly opened his mouth, handing Tang Hongye one of the pieces of wood with nails on it, "Just look at the nails on the wooden planks that seal the small window of the warehouse." ”

Tang Hongye took the piece of wood from Dai Xu's hand, looked at the nails on it, and frowned.

The plank itself was not a good new piece of wood, and it didn't look wrong, but the nails on it were shiny and silvery, and it looked new and clean, without any rust on it.

Although Tang Hongye does not have the skills to do carpenter's work, but there is still some common sense, he knows that ordinary carpenters will like to wet the iron nails with saliva when nailing, so that the iron will rust, enhance the friction with the wood, and play a role in reinforcement, or even if it is not artificially done, in such a rainy season, there will be a big or small rain every three or five days, the environment outside the warehouse is relatively humid, if the window of the warehouse is sealed for a little time, Iron nails will naturally rust and become rusty inside the formwork that absorbs moisture and moisture, so how can they be kept so clean and clean.
