Department of Psychology Forensic

Chapter 123
property!

The on-site trace inspectors were also secretly listening to the conversation between Zhou Zheng and Cui Jun. After hearing this sentence, their hearts moved.

Several trace inspectors looked at each other, and they all saw the same information in each other's eyes.

"No belongings of the deceased were found at the scene." One of the trace inspectors said.

"Is there nothing?" Cui Jun asked immediately.

"Yes, there is nothing, only the dead here." The trace inspector replied.

"Understood." Cui Jun nodded, looked towards Zhou Zheng, and said in a deep voice, "It seems that you are right."

Zhou Zheng looked down at the corpse, remained silent and did not speak.

The cleaning lady took away the deceased's belongings, which is an obstacle to the police handling the case and will be punished accordingly.

What made him sigh was that after the cleaning lady saw the deceased, her first reaction was to take away the deceased's belongings, and then she chose to call the police.

The items of the deceased are very important to the detection of the case. The most important thing is that they can be used to confirm the identity of the deceased. In addition, some hidden information may also be discovered.

However, there is no complete conclusive evidence now, and it cannot be determined whether the deceased's items were taken by the cleaning lady or the murderer.

"We continue."

Cui Jun looked at the corpse. He gently pressed down on the dead man's head with his gloved hand, and he could hear the sound of cracking bones.

"The deceased's skull was fractured, but..."

Cui Jun gently pushed aside the deceased's hair, searched around the scalp, and said in a deep voice: "The deceased's head has no obvious trauma, no open wound, combined with the deceased's skull fracture, it should be covered by a soft texture blunt force blow."

Cui Jun continued to inspect the injuries on the deceased. He rolled up the sleeves and clothes of the deceased, exposing the skin.

"There are flushes on the chest, abdomen and limbs of the corpse, which should be blow wounds. The deceased did have a fierce fight with others." Cui Jun said slowly: "The murderer's method of killing is not the same as the method of killing Zhang Chi. !"

"The murderer should not be the same person." Zhou Zheng frowned and made a judgment. He didn't touch the corpse, but through the screen of the camera, he could see some clues.

"Tell me." Cui Jun said with great interest. When he spoke, he did not stop the inspection steps, and began to inspect the neck and mouth of the deceased. Injury, a mouthful of teeth were pulled out violently, there was no other damage to the face, the cornea was moderately cloudy, and there was no sign of mechanical asphyxia. The specific cause of death can only be determined by further autopsy, and the initial suspicion may be craniocerebral injury."

"The murderer who killed Zhang Chi should be a woman." Zhou Zheng's eyes flickered, and he believed in his own judgment as much as possible, but he had to say that the two cases had the same symbols, and the dead were father and son. The performance was completely different, he continued: "The murderer who killed Zhang Xin was a man."

"Portrait?" Cui Jun looked up at Zhou Zheng, with a flash of appreciation in his eyes.

"I have too little evidence in my hands, and the portrait model that can be made is very small, but at least I can determine the gender of the murderer." Zhou Zheng said in a deep voice.

"Can't you make a mistake?" Cui Jun asked.

"I don't know." Zhou Zheng was stunned by this question. If there was no such connection, he could boldly confirm it. However, if it was a coincidence, it would be too coincidental. Then he said: "The one who killed Zhang Chi The murderer doesn’t look like a man, master, think about it, isn’t it a bit strange for a man to cook at Zhang Chi’s house! Moreover, if it is really the same murderer with such violent tendencies, there is no need to poison him, Zhang Chi The murderer of the case obviously did not want Zhang Chi to struggle."

Cui Jun listened carefully to Zhou Zheng's analysis. There are many possibilities here. He also thought about it. When listening to Zhou Zheng's reasoning, he could piece together these logical chains.

The same symbols appeared at the scene, and the teeth of the two corpses were pulled out, and the teeth were pulled out alive, not after death.

In addition, the two victims who died one after another were still father and son.

Such two points are intertwined, but any criminal investigator with a keen nerve will connect them together, intuitively thinking that this is the same murderer.

but……

What Zhou Zheng said makes sense!

The murderer in the Zhang Chi case seemed to be a woman, while the murderer in the Zhang Xin case was obviously a man.

There is a difference in gender, which is enough to show that it is not done by the same person.

Is it really a coincidence?

Cui Jun frowned when he thought of this, and he faintly felt that something was wrong. They seemed to have missed some important information, but now they couldn't figure out the train of thought at all.

"The murderer in the Zhang Chi case used GHB, which shows that she is not physically a match for Zhang Chi, and cannot gain a positive advantage in a one-on-one entanglement. This can be seen from the fact that Zhang Chi was pulled out of his teeth and strangled to death immediately after being stunned."

Zhou Zheng's brain was spinning rapidly, and his thoughts were jumping very fast. He found that he could still make inferences when the case was solved, but it was somewhat difficult to make a complete criminal psychological portrait like he did at the beginning.

Of course, he also found an excuse in his heart. After all, these are two different murderers, which means that they are different cases, and there is no way to connect with each other as evidence, so it is difficult to draw a specific portrait of the suspect.

"When the murderer pulled out Zhang Chi's tooth, Zhang Chi should have felt a very strong pain, so he might be in a state of waking up, so she strangled Zhang Chi immediately!"

"As for Zhang Xin's case, judging from the broken items at the scene, it should be used by Zhang Xin to throw and fight with the murderer. There are a lot of debris at the scene, indicating that the fight was very tragic. There are also many wounds on Zhang Xin's body, which clearly shows that the murderer Physically confident, he knows he can kill Zhang Xin single-handedly."

"From this point of view, the murderer will not be a woman, but a man, or a man with a violent personality."

"The murderer probably didn't know Zhang Xin, but he was able to enter the hotel room. I suspect that Zhang Xin might have ordered a takeaway."

"This can be confirmed by checking Zhang Xin's mobile phone records, or from the hotel's surveillance. If my guess is correct and the murderer is indeed sent outside, then he has the ability to poison, but he does not. It further shows that he is not the murderer of the Zhang Chi case."

Zhou Zheng quickly narrated the thoughts that emerged in his brain, and while he was speaking, his face became ugly and dignified.

Since the murderer is not the same person.

then have the same sign again.

Are these two murderers together?
One male and one female?
Like, but not like!
After all, if the two murderers knew each other and wanted to commit crimes together, they could cooperate with each other.

However, judging from the two crime scenes, they are completely different and complete scenes, and there is no trace of cooperation.

Is it really such a coincidence?

Zhou Zheng's brain was thinking quickly, and he carefully thought about whether he had missed any details, but judging from the information he had so far, he could only draw such a conclusion.

This made him couldn't help but doubt himself, whether he really thought too much, there are some unexpected coincidences in the world, but two different murderers have the habit of pulling out the teeth of the deceased...

"Let's transport the body back for an autopsy. It's hard to see other problems from the damage on the body surface." Cui Jun signaled Zhou Zheng to take out the body bag and bring the body back to the forensic center.

"Yes." Zhou Zheng responded, put down the camera in his hand, took out the prepared body bag, and cooperated with Cui Jun to put the corpse into the body bag.

After the corpse was taken away, the on-site inspection gradually came to an end. The people from the trace inspection department came earlier, and the follow-up finishing work was relatively smooth.

Through on-site communication, Zhou Zheng got some information that not only broken objects were collected in the hotel room, but also a lot of footprints were collected, and he was going to take them back for footprint identification.

Since it is a hotel, and the Golden Week has just passed, a lot of fingerprints were detected in the hotel room facilities, and it is difficult to identify the old and new, which makes the fingerprints collected on the spot worthless.

There is no way, the hotel is like this. The cleaning lady often just changes the bed sheet and quilt cover to sweep the floor, and sweeps the garbage on the ground. The water is poured and it's over.

The cleaning lady has such a heavy workload every day, it is obviously unrealistic to expect her to do her best like cleaning her own house.

I don’t take it that seriously at ordinary times, let alone during Golden Week, when the traffic is the largest.

The hotel Zhang Xin lives in is not a high-end hotel. To be precise, it is the kind of cheap fast hotel, such as the TV in the room. If you take a random sample, you can find many fingerprints, one covered with another, and you can’t even tell each other apart. .

This phenomenon will also appear on the cabinet, table, chair, bedside table and so on.

Even the flush button of the toilet can take a lot of fingerprints.

With so many fingerprints, even if the murderer carelessly left fingerprints on the scene without wearing gloves, it is impossible to find out which one was left by the murderer.

This virtually brings many difficulties to the detection.

"Forensic Cui!"

Just when Zhou Zheng and Cui Jun were about to leave, Zhao Lei's voice sounded from the door, and he hurried in with a slightly uneven breath, and said, "I have investigated the matter of the cleaning lady, she did come in to see When the deceased was dead, she went into the hotel room and called the police after she found out that the person was dead. She didn’t say that she was afraid of being misunderstood as a suspect.”

"She didn't tell you anything else?" Cui Jun asked with a sneer.

"Anything else? What's the matter?" Zhao Lei was full of question marks.

"Zhao Lei, go ask her again what she took. You criminal police are the best at scaring people. In short, you must let her tell the truth." Cui Jun's tone was strong. Displeased, the items of the deceased in the murder case are very important, which will affect the nature of the case. At least at this time, they have no way to determine whether it is seeking revenge or seeking money.

"Damn!" Zhao Lei couldn't help cursing angrily, stopped talking nonsense, turned around and left, he had just asked the cleaning lady, knew the location of the latter, and hurriedly chased after her before he was far away, muttering cursingly: Why haven't you told me the truth yet!"

……

Municipal Bureau, Forensic Medicine Center, Dissection Room.

The corpse lay flat on the dissecting table with the face facing up, fully exposing the face.

Cui Jun and Zhou Zheng were neatly dressed and separated from each other. The camera responsible for video recording was hung on a bracket purchased with huge sums of money, silently recording everything in the anatomy room.

When Zhou was putting the body into the body bag, he could clearly see the appearance of the deceased.

It is indeed Zhang Xin!
Although Zhang Xin's ID card was not found at the scene, they had just chatted this morning, and with his amazing memory, a simple comparison could confirm that the deceased was Zhang Xin.

Zhang Xin went after all!

Zhou Zheng looked at Zhang Xin who was lying on the dissecting table as if sleeping peacefully, and he couldn't help but sigh in his heart. This man was widowed in the middle age and lost his son in old age. His fate was miserable enough, and now he followed suit.

Cui Jun touched the joints of the corpse, and with a little force, he could feel the blockage, as if the corpse was tightening.

"The corpse already has weak rigor, Zhou Zheng, help me open the rigor at the shoulder joint, and we will take off his clothes." Cui Jun raised his arm on this side, Zhou Zheng heard After his words, do the same.

The dead man's two arms were raised continuously, and after the tense joints made a crisp sound, the joint activities returned to normal.

After being able to move freely, Zhou Zheng and Cui Jun raised the arms of the deceased, took off the clothes and trousers, and presented the corpse on the dissection table in its entirety.

"Alcohol."

Cui Jun stared at the corpse, and now there were patches of dark red corpse spots on the lower part of the body surface, these corpse spots concealed the original red scars to a certain extent.

At this time, using alcohol to wipe the epidermis of the corpse can use the volatility of alcohol to take away the moisture on the skin on the body surface, and increase the permeability of the skin, making the subcutaneous damage clearer and easier to identify.

"coming."

Zhou Zheng used tweezers to hold the alcohol cotton ball, and wiped the body surface of the corpse inch by inch. As he wiped, the blush became clearer.

"Bamboo hits the hollow."

Cui Jun looked at the wounds on the corpse one by one, showing a pale center with parallel stripes and bordered contusions on both sides, and immediately said: "It seems that the wounded object is a soft stick."

Zhou Zheng nodded silently when he heard his master's words. The appearance of the special form of contusion, which is hollow by bamboo hitting, shows that the wounded object is a cylindrical stick.

Bamboo-beating hollow refers to a special form of contusion formed by a round stick-shaped injury vertically hitting the part with rich soft tissue.

This is because when the stick hits a flat position, the blood in the capillaries of the force-bearing part quickly accumulates toward both sides, causing the capillaries in the soft tissues on both sides of the contact surface to rupture, forming two parallel bleeding bands.

If there is a hollow phenomenon on the corpse, it can be determined that the wounded object is a cylindrical stick, and the width, diameter and shape characteristics of the stick can be clearly reflected.
