In Xu Hao's eyes, there was a hole the size of a pore, which was pressed down by the clothes on the victim's back and neck. If it weren't for the blessing of eagle eyes, he wouldn't have noticed it.

Is this related to the case?

Is it the victim's own problem or is it left behind by the murderer?

A picture flashed through Xu Hao's mind, and countless questions poured out.

"The name of the deceased is Liu Wei. He is 24 years old. He is a male and an orphan. He is the only one in the family. He renovated the post office and opened up the walls of his home behind the post office to connect them together. He has good friends and good personality. He receives regular physical examinations.

The body is also in good condition..."

While Li Xiang was talking about the deceased's information, he looked at Xu Hao. The moment he noticed the change in his expression, his eyes lit up.

"What, what did you find!?"

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

Entity information needs to be verified. If you say it without verification, it will most likely affect other people's thinking 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 struggled, but did not resist," Xu Hao said.

Hearing this, Li Xiang was stunned for a moment, then frowned and said: "The police have already grasped your problem. Is there anything else?"

"There are many."

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

"Team Li, have you ever heard of 'Locard's Law of Matter Exchange'?"

Li Xiang:???

"What are these laws of matter?"

Li Xiangmeng was confused. For someone like him who handles cases purely based on experience and has not received systematic training, this kind of summary knowledge is very unfamiliar.

"Locard's law of material exchange is a theory derived from the Gallic forensic scientist and criminologist Edmond Rocard."

Xu Hao 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, 'Every contact must leave traces'!"

"To put it simply, after the murderer committed the crime, the blood he left behind, the knife handle 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 are all the characteristics of the murderer that can be seen from them!"

Hearing this, Li Xiang nodded thoughtfully.

Su Yue next to her frowned.

Is there such a person in Gallic Chicken? This theory is very valuable, why didn’t the teacher at the police academy mention it?

In fact, there is no such person as Edmond Rocca in this world, but Xu Hao was too lazy to explain and simply let a few people around him figure it out.

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

Xu Hao glanced at him with disgust.

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

"What did you see?"

After checking the face of the victim on the ground to confirm that there were no clues, it was covered with a white cloth.

His limbs were paralyzed on the ground, arranged in a "big" shape, and there were no obvious injuries on his body.

The surrounding shelves and chairs have not been touched. In short, there are no signs of struggle, as if they are willing to die.

But the strange thing is that Xu Hao opened the white cloth and found that the victim's expression was extremely ferocious, and even if he died, there was still fear of death in his eyes!

The two are completely opposite and contradictory!!!

Li Xiang thought for a moment and then asked, "The murderer was physically superior and controlled the victim, making him unable to resist?"

Su Yue also put forward her own opinions.

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

Listening to the two people's opinions, Xu Hao nodded. When no one spoke, he smiled and pointed at the corpse.

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

"Assuming that the murderer's physical strength crushed the victim, making him unable to move, and finally having his heart ripped out, then..."

"The murderer used his physical strength to crush the victim and control the traces of the deceased?"

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

Li Xiang and the two looked in the direction he pointed.

"The victim's physical condition is good, not sub-healthy, but a normal male, 1.77 meters tall, weighing 150 pounds by visual inspection."

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

."

"But the corpse obviously does not have this feature, it looks like a suicide."

"As for the moon..."

Xu Hao thought about Su Yue's guess, thought about it and replied:

"Your guess is possible, but people have stress reactions. The facial features show that the murderer most likely performed the dissection while the other party was alive and awake. This level of pain, the body's instinctive desire to survive,

Will give priority to the brain to resist."

"So, relying on threats alone, it is unlikely."

Saying that, Xu Hao paused, looked up at Li Xiang, and spoke with a smile.

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

"So, for subsequent investigations and arrests, the strong men can be changed into foreign objects that can easily subdue men!"

Li Xiang was stunned for a moment, and then he suddenly realized something.

Lockard's law of material exchange is to broaden your thinking.

Don’t just limit yourself to looking for clues in front of you, but try to think about the meaning of traces on the scene!

After thinking for a long time, Li Xiang suddenly laughed and said, "Yes, this theory is good. I will tell Lao Zhao about it when I get back!"

Su Yue also made a note secretly, planning to check on this person named Edmund Rocca when she goes back.

Xu Hao has been observing the deceased himself.

He just published the novel yesterday, but the contract hasn't been sent out yet, and the manuscript hasn't been saved yet. He can't waste too much time in detention.

He focused his eyes on the deceased, the only fatal injury that was conspicuously visible!

The wound is very scary, it is like a cave. The position of the heart is accurately found, and then the cut is carried out. No cut is unnecessary!

Xu Hao frowned, and four questions came to his mind.

1. What is the thing that looks like a pinhole on the back of the neck? Is it accidentally done by the victim himself, or is it a trace left by the murderer!?

Second, there are many types of knives that can penetrate ribs, but there are not many knives that can penetrate ribs and accurately cut various blood vessels and arteries.

What kind of knife is this? How did the murderer buy it?

Third, the murderer can accurately find 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 stunned for a moment, then put his hand on his chest in doubt, "What's going on, little brother?"

Xu Hao didn't reply. He turned to look at Officer Xiaoliu.

"Officer Liu, please feel your heart."

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

Seeing the area covered by the two men, Xu Hao's frown deepened!

Both of their hands covered the upper left side of the chest and the right side of the accessory breast under the armpit. This is the chest. Although the heartbeat can be clearly felt, the heart is not here!

The heart should be located further down and in the middle, between the second and fifth ribs.

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

After thinking for a while, Xu Hao focused on 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 has proved that the other party's intention was not the heart.

Then why go to such great lengths to cut out the heart!?

Xu Hao frowned, thought for a moment, and then looked up at Li Xiang.

"Captain Li, have you found the victim's dissected heart?"
Chapter completed!
