If there is a doubt, it must be resolved, and if there is a doubt, the case cannot be closed.

This is our duty as criminal police officers and forensic doctors, and it is also our inner responsibility to have a clear conscience.

We returned to the scene of the crime again, and this time, our goal was clear: to find a hard, blunt object that could penetrate deep into the deceased's mouth and reach the throat.

"Are you so sure he killed? Even if he killed, are you so sure that the murder weapon used by the murderer must still be in this room? Jiang Tingbai suddenly asked me.

To be honest, I'm not sure.

Moreover, I'm not even sure if this is the scene of the first crime.

"If it was really him, the murderer would definitely leave the murder weapon at the scene of the crime." Li Meng said suddenly.

"Oh? Sister Li Meng, are you so sure? Jiang Tingbai couldn't believe it.

I also looked at her in disbelief, how could she be so sure?

Li Meng calmed down, slowly spoke, and said: "The murderous method of using a hard object against the throat of the deceased, causing a heavy injury to the central nervous system in the back of the deceased's head, was definitely not planned by the murderer in advance. Because to deal with a deeply drunk and incapable man, there are thousands of ways to kill people. The deceased could be said to be a piece of fish at that time, which was left to be slaughtered. And the murderer did not dare to guarantee that when using this method of killing, he would be able to accurately grasp the strength of his own attack, after all, the probability of the deceased vomiting causing vomit to enter the trachea is too small. ”

Neither of us spoke, and we listened to her continue.

"Objects that can reach the throat should be at least fifteen centimeters, and they should be hard enough and have a coarse diameter blunt object. The laryngeal cap is a leaf-like valve, if the diameter is not thick enough, or if it is not blunt enough, it will cause bleeding from the laryngeal capsule, not redness and swelling, and it will not even affect the central nervous system of the deceased and cause death, and there are no eligible items in our belongings. Li Meng continued.

Li Meng is a woman, she may not have imagined that we really have such a thing in us.

It's just that in the face of a drunk man, coupled with the inner tension when killing someone, that thing simply can't reach the level of hard enough.

"So, this way of killing people by the murderer was improvized?" Lin Zifan suddenly asked her.

Li Mengmeng thought about it, nodded and said, "According to my criminal psychology analysis, it is like this. ”

She finished and turned her gaze to me.

Looks like it's up to me to say something next.

I still use the way of thinking that I am most familiar with and what I am best at, that is, to put myself in the perspective of a murderer.

"If Du Tan is so drunk that a hard object enters his throat and he doesn't wake up and struggle to resist, then he has absolutely no way to go home by himself.

If I were the murderer, I would definitely pretend to be Du Tan's friend and send Du Tan home. This caused the doors and windows to be unbroken, and then I put Du Tan on the sofa and began my murder plan. But I didn't think about how to kill him, I just knew that I had to kill him.

I would look for a suitable murder weapon at Du Tan's home, but it was not easy to find, because the more troublesome I used to kill, the more clues I would leave behind.

In particular, blood stains will reveal a lot of clues, and I urgently need to think of a way to kill people without seeing blood.

Finally, I found a suitable murder weapon, and just as I was about to kill someone, I decided to put the murder weapon into Du Tan's mouth, severely wounding his central nervous system and causing his death.

I wanted to stab him to death, but his sudden vomiting made me feel a little palpitating, and I was afraid that he would suddenly wake up and resist, but before I could come back to my senses, he had already suffocated to death.

If I took the murder weapon away, the police would have determined that Du Tan had killed him because something was missing in his room, so I cleaned the murder weapon and put it back in the distance, and at the same time carefully cleaned the crime scene, erasing all fingerprints and footprints I left behind......"

After listening to my description, Jiang Tingbai not only applauded me sincerely: "You are a brainchild, if you don't write a novel, you will be blind to your talent." ”

I smiled slightly, and then imitated Jiang Tingbai's tone and said, "Low-key!" Low profile! ”

"The two of you can combine and complete a perfect crime." Xue Hang said quietly.

"But I always feel that Li Meng is using criminal psychology to distract him, and you are just guessing nonsense." Lin Zifan pursed his mouth and said with some disdain.

"Hey! Why am I just guessing nonsense, I have also carefully analyzed it, okay! I was a little unconvinced, and immediately retorted.

But to be honest, I'm really guessing all of this, isn't criminal psychology speculation?!

Too lazy to argue with them, our priority is to find a murder weapon in this room that suits our standards.

Everyone looked separately, the living room, bedroom, kitchen, bathroom, balcony, we did not let go of any corner, did not let go of any item.

"Is this okay?" Jiang Tingbai took out a flashlight from the TV cabinet.

"Can you put him in your mouth and up your throat?" I let out a sneer, but in order to save him some face, I thought about it for a while, and said, "If you think it's appropriate, you can take it back, and then check it for the saliva DNA of the deceased." ”

"I think this is a good fit!" Li Meng suddenly let out a shout in the bathroom.

In the next scene, she walks towards me with a broom in her hand.

This one was indeed long and hard enough, so that when I saw this broom, I inexplicably substituted for the deceased, and felt some discomfort in my throat, and even some retching.

"Take them all back and see if you can test your DNA." I shrugged, and while I thought the broom was unlikely, I couldn't let go of a single suspicious item.

I walked into the kitchen and looked around for suspicious items, because the kitchen had the most things that met the criteria.

Spoons, chopsticks, and ......

The next second, I set my eyes on the baguette in the kitchen.

Baguettes, after a long period of storage, can become as hard as a brick after the moisture has completely evaporated.

Killing people with bread is indeed accidental enough, and it is also in line with the accidental death of the deceased.

And even if the bread is placed at the scene of the crime, the police will not think that the murderer will use the bread to kill people.

I put on the gloves I used to survey the site, and once again picked up the baguette and examined it carefully, which was very much in line with our goals in terms of appearance and quality.

If I were a murderer, I would definitely choose to use this......
