In the detention center, the suspect is myself

Chapter 15 The Law of Exchange, Four Questions!
In Xu Hao's eyes, there was a hole the size of a pore on the victim's back and neck, which had been pressed by the clothes. If it weren't for the blessing of the eagle eye, he would not have noticed it.

Does this have anything to do with the case?

Is the victim's own problem or the murderer's legacy?

Pictures flashed in Xu Hao's mind, and countless questions flooded out.

"The name of the deceased is Liu Wei, 24 years old, male, orphan, he is the only one in the family, the post office was remodeled by him, and the wall behind the post office was opened up to connect them together. He made good friends and had a good personality. good"

While talking about the information of the deceased, Li Xiang looked at Xu Hao, and his eyes lit up the moment he noticed the change in his slight expression.

"What, what did you find!?"

He asked aloud, Xu Hao thought for a while, but did not mention the pinhole.

Substantial information needs to be verified. If it is said without verification, there is a high probability that it will affect the thinking of others and waste time.

He glanced at the crime scene inside the post office, and said:

"Some discoveries."

Li Xiang was overjoyed, "What did you find!?"

"The deceased wanted to struggle, but he didn't resist," Xu Hao said.

Hearing this, Li Xiang was taken aback, then frowned and said, "The police have already taken care of your problem, is there anything else?"

"A lot."

Xu Hao squatted down and silently observed the cave in his chest.

"Captain Li, have you heard of 'Local's Law of Material Exchange'?"

Li Xiang:? ? ?
"What the hell is the law of matter?"

Li Xiang was caught off guard. For someone like him who handled cases purely by experience and had no systematic training, this kind of summative knowledge was very unfamiliar.

"Local's law of material exchange is derived from the theory summarized by Edmund Rocca, a forensic scientist and criminologist in Gaul."

Su Xuhao looked at Li Xiang's puzzled eyes, thought for a while, and explained.

"It sounds complicated, but it can be summed up in eight words, 'Where there is contact, there must be traces'!"

"To put it simply, after the murderer committed the crime, the blood he left behind, the handle of the knife he touched, the ground he stepped on, including but not limited to fingerprints and hair, and even the air he breathed, are all traces of him! "

"And these traces can be seen from the characteristics of the murderer!"

Hearing this, Li Xiang nodded thoughtfully.

Su Yue next to her frowned.

Does Gallic Chicken have this guy?This theory has a lot of gold content, why didn't the teacher of the police academy mention it?

In fact, there is no such person as Edmund Rocca in this world, but Xu Hao didn't bother to explain, so he simply let the few people around him make up their own brains.

"What does this theory have to do with the case?" Li Xiang frowned. He knew, but he didn't understand the meaning of the theory.

Xu Hao gave him a disgusted look.

"Captain Li, for example, as I said just now, the victim wanted to resist, but there was no sign of struggle."

"What did you see?"

The faces of the victims on the ground were checked and after confirming that there were no clues, they were covered with a white cloth.

His limbs were limp on the ground, placed in a "big" shape, and there was no obvious trauma on his body.

The surrounding shelves and chairs have not been touched, in short, there is no trace of struggle, as if willing to die.

But what was strange was that when Xu Hao lifted the white cloth, he found that the victim's expression was extremely ferocious, and the fear of death remained in his eyes even after death!
These two are completely opposite and contradictory! ! !

Li Xiang thought for a moment, then said, "The murderer has superior physical fitness, controlled the victim so that he couldn't resist?"

Su Yue also put forward her own opinion.

"What if the murderer threatens the victim and keeps him from moving?"

Listening to the opinions of the two, Xu Hao nodded, and when no one spoke, he pointed to the corpse with a smile.

"First of all, Captain Li, what you think is indeed possible, and what you said about Moon is also right."

"Assuming that the murderer's physical fitness crushed the victim, making him unable to move, and eventually his heart was dug out, then"

"The murderer used physical fitness to crush the victim, so as to control the traces of the deceased?"

Xu Hao pointed to the victim's neck, his finger touched the wrist, and then stopped at the joint.

The eyes of Li Xiang and the two followed the direction he pointed.

"The victim's physical fitness is good, not sub-healthy, but a normal male, with a height of 1.7 meters 150 and a visual estimate of [-] catties."

"This kind of physical quality, even if the murderer crushes him, if he wants to completely control it, he must hit the opponent's vital parts on the joints, neck, or other vital parts. However, these control methods will inevitably leave bruises and other symptoms on the body. .”

"But the corpse obviously doesn't have this feature, it's like suicide."

"As for the moon."

Thinking of Su Yue's guess, Xu Hao thought for a while and replied:
"Your guess is possible, but people will have a stress response. The facial features show that the murderer most likely performed the heart-section while the other person was alive and awake. This level of pain, the body's instinctive desire to survive, It will give priority to the brain consciousness to resist."

"So, on threat alone, it's unlikely."

After speaking, Xu Hao paused, looked up at Li Xiang, and smiled.

"From the exchange of killing traces just now, we got a point of information. The murderer does not need to rely on the body to suppress, but other levels, relying on external objects for help!"

"So, in the subsequent investigation and arrest, we can change from a strong man to something that can easily subdue a man!"

Li Xiang was taken aback for a moment, and then suddenly realized something.

Locar's law of material exchange is to broaden one's thinking.

Don't be limited to looking for the clues in front of you, but try to think about the meaning of the traces on the spot!

After thinking for a long time, Li Xiang suddenly smiled and said, "That's right, this theory is good, I'll tell Old Zhao when I get back!"

Su Yue also made a note secretly, planning to check this man named Edmund Rocca when she went back.

Xu Hao had been observing the deceased himself.

He just published the novel yesterday, the contract hasn't been sent yet, and the manuscript hasn't been saved yet, so he can't waste too long in the detention center.

He focused his eyes on the dead body, the only fatal injury that could be seen conspicuously!
The wound was horrifying, it was just a cave, the location of the heart was precisely found, and then cut, no knife was superfluous!

Xu Hao frowned, four questions came to his mind.

[-]. What is the suspected pinhole on the back of the neck?Was it the victim who did it accidentally, or the traces left by the murderer! ?
[-]. There are many types of knives that can pass through the ribs, but there are not many knives that can pass through the ribs and accurately cut various blood vessels and arteries.

What kind of knife is this?With what identity did the murderer buy it! ?
[-]. The murderer can accurately find out the location of the heart and perform precise cutting!

Xu Hao frowned and thought for a moment, then raised his head and looked at Li Xiang.

"Captain Li, feel your heart with your hands."

Li Xiang was taken aback for a moment, then put his hands on his chest in doubt, "What's the matter, little brother?"

Xu Hao didn't reply, he turned to look at Police Officer Xiaoliu.

"Officer Liu, please feel your heart too."

Liu Liu also put his hands on his chest in a daze.

Seeing where the two of them were covering each other, Xu Hao's frown deepened!

The hands of both of them were covering the upper part of the left chest and the right part of the underarm breast. This is the chest. Although the heartbeat can be clearly felt, the heart is not here!
The heart is lower and more central, between the second and fifth ribs.

But this is the reaction of normal people. Ordinary people can't find the exact location of the heart, but the murderer can!

After thinking for a while, Xu Hao turned his attention to the fourth question.

What is the purpose of the murderer cutting out the heart! ?

transplant?

No, the murderer randomly threw the heart in the trash can, which proved that the other party's goal was not the heart.

Then why did it take so much effort to cut out the heart! ?
Xu Hao frowned, thought for a moment, then looked up at Li Xiang.

"Captain Li, have you found the victim's severed heart?"

"Take me to see the heart!!!"
