In Xu Hao's eyes, a hole the size of a pore, at the back and neck of the victim, was pressed by the clothes all the time, and if it weren't for the blessing of Eagle Eye, he wouldn't have noticed it.

Is there a connection to the case?

The victim's own problems or the murderer's legacy?

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

"The deceased's name is Liu Wei, 24 years old this year, male, orphan, he is the only one in the family, the post office was modified by him, the wall of his house behind the post office was opened, connected together, good friends, good character, regular physical examinations, and good health......"

Li Xiang looked at Xu Hao while talking about the deceased, and the moment he noticed the change in his micro-expression, his eyes lit up.

"What, what did you find!?"

He asked out loud, Xu Hao thought about it, and didn't say the pinhole.

Entity information needs to be verified, and if it is said without verification, it will most likely affect the thinking of others and waste time.

He glanced at the crime scene inside the post office and spoke:

"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 mastered your question, is there anything else?" ”

"Much."

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

"Team Lee, have you heard of the 'Lokar Law of Material Exchange'?"

Li Xiang: ???

"What the law of matter is Luo?"

Li Xiang is circled, and for a person like him who relies purely on experience to handle cases and has not undergone systematic training, this kind of summary knowledge is very unfamiliar.

"Locar's law of material exchange is derived from a theory summarized by the forensic scientist and criminologist Edmund Rocca of the Gallic chicken."

Su Xuhao looked at Li Xiang's puzzled eyes, thought about it, 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, the blood left by the murderer after committing the crime, 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 can be seen from the characteristics of the murderer!"

Hearing this, Li Xiang nodded thoughtfully.

Su Yue next to her frowned.

Does the Gallic chicken have this person? This theory has a high gold content, why hasn't the police academy teacher mentioned it?

Actually, there is no such person as Edmund Rocca in this world, but Xu Hao didn't bother to explain, so he simply let a few people next to him make up for it by themselves.

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

Xu Hao glanced at him with disgust.

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

"What do you see?"

The victim's face on the ground was examined and confirmed that there were no clues, and it was covered with a white cloth.

His limbs were limp to the ground, placed in a 'large' shape, and there were no obvious external injuries on his body.

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

But the strange thing is that Xu Hao lifted the white cloth and found that the victim's expression was extremely hideous, 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 spoke, "The murderer has the advantage of physical fitness, controlling the victim so that he can't resist?" ”

Su Yue also put forward her own opinions.

"What if the murderer threatens the victim and doesn't allow him to move?"

Listening to the views of the two, Xu Hao nodded, and when no one spoke, he smiled and pointed to the corpse.

"First of all, Team Li, your idea does have this possibility, and what you said is right."

"Suppose that the murderer's physical fitness crushes the victim, making him unable to move, and finally he is tragically gouging out his heart, then ......"

"What about the murderer who crushes the victim through physical fitness, so as to control the traces of the deceased?"

Xu Hao pointed to the victim's neck, and his fingers slashed to his wrist before stopping at the joint.

Li Xiang's eyes followed the direction he pointed.

"The victim's physical fitness is good, not sub-healthy, but a normal man, 1.77 meters tall, 150 pounds visually."

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

"But the corpse apparently does not have this characteristic, as if it were a suicide."

"As for the ..... of the moon"

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

"Your guess is possible, but people will have a stress response, facial features show that the murderer is likely to dissect the other party alive and awake, this level of pain, the body's instinctive desire to survive, will give priority to the brain consciousness to resist."

"So, it's not very likely to rely on threats alone."

As he spoke, Xu Hao paused, he looked up at Li Xiang and said with a smile.

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

"Therefore, the subsequent investigation and arrest can be changed from a strong man to a foreign object that can easily subdue a man!"

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

Lokar's law of material exchange is to open your mind.

Don't just look for clues in front of you, but try to think about what the traces of the scene represent!

After thinking for a long time, Li Xiang suddenly smiled and said, "Yes, this theory is good, go back and tell Lao Zhao to listen!" ”

Su Yue also secretly made a note of it, and planned to check this person named Edmund Rocca when she went back.

Xu Hao has been observing the deceased himself.

He just released the novel yesterday, the contract hasn't been sent yet, and the manuscript hasn't been saved, so he can't afford to waste too much time in the detention center.

He focused his gaze on the deceased, the only mortal wound that could be seen conspicuously!

The wound is terrifying, it is a cave, the location of the heart is accurately found, and then the cut is performed, and no knife is superfluous!

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

1. What is that suspected pinhole on the back of the neck? Was it accidentally done by the victim himself, or was it the traces left by the murderer!?

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

What kind of knife is this? In what capacity did the murderer buy it!?

3. The murderer can accurately find out the part of the heart and perform precise cutting!

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

"Team Li, you feel your heart with your hands."

Li Xiang was stunned for a moment, and then put his hand on his chest in disbelief, "What's the matter, little brother?" ”

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

"Officer Liu, please feel your heart too."

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

Seeing the place where the two of them were covering, Xu Hao's brows furrowed even deeper!

The hands of the two of them are all covering the left chest up, and the armpit accessory breast is on the right, this is the chest, although the heartbeat can be clearly felt, but the heart is not here!

The heart should be lower and more centered, 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 about it, Xu Hao turned his attention to the fourth question.

What was the purpose of the murderer's dissecting the heart!?

Graft?

No, the murderer casually threw the heart in the trash, which has proved that the other party's purpose is not the heart.

So why do you have to put so much effort into cutting out the heart!?

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

"Team Li, did you find the victim's severed heart?"

"Take me to see the heart !!"
