Department of Psychology Forensic

Chapter 42 The Killing Ringtone
After Cui Jun quickly shaved off the dead man's hair, he stared at the bald head, and he could see the obvious color on the occipital part of the back of the head.

"The deceased's head and back of the neck had no obvious damage, and there were dark purple corpse spots on the occipital!"

Cui Jun pressed down on the scalp on the occiput of the head. As he pressed his fingers on the spot, he pressed so hard that even his fingernails turned white, but the color on the scalp did not appear. any impact.

Immediately afterwards, he took out the scalpel, scratched towards the spot of the corpse, and looked at the section of the tissue.

"The corpse plaque is completely fixed, and will not disappear when pressed. The tissue cells have been stained dark red, and no blood flows out from the cross-section of the blood vessel. This is the corpse plaque in the infiltration period. The victim died for more than 24 hours, and the deceased died of mechanical asphyxia. , The blood of the dead body does not coagulate and is easy to precipitate, so it should be decapitated after a period of death." Cui Jun said in a deep voice.

"This victim should have been killed earlier than the victim in the morning." Zhou Zheng nodded.

"The heads of the two victims were chopped off after death. The murderer disposed of the bones and tissues of the head and neck, and poured plaster into it. As long as we test the solidification time of the plaster samples, the final results will be similar. If so, it can be proved that the two victims were beheaded at the same time." Cui Jun analyzed: "In this way, it can be inferred that the second victim died at least one day earlier than the first victim."

After all, Cui Jun looked at Zhou Zheng and said, "Help me up, I'm going to dissect the head."

"Okay." Zhou Zheng immediately supported both ends of the head with both hands. Even though he had already undergone a craniotomy autopsy, he still felt nervous.

Cui Jun went to get the craniotomy saw after explaining, and then opened the dead man's head with a piercing roar.

This time it was a little smoother than in the morning, but Zhou Zheng still felt some bone meal floating towards his face, and there was an indescribable stench in the air.

The stench became more obvious after Cui Jun removed the dura mater at the base of the deceased's skull, just like lifting the manhole cover of the sewer, and the stench began to diffuse in the dissection room.

"The brain tissue of the deceased has begun to decay, and there are still large black-blue bleeding spots on the petrous part of the temporal bone. The signs of suffocation are obvious. The cause of death of the deceased was mechanical asphyxiation."

After Cui Jun finished the autopsy, he cooperated with Zhou Zheng to take a few photos, and did not ask any more questions, and started to suture directly.

At this point in time, it was obvious that Cui Jun was exhausted and his eyelids were fighting, but he still insisted on completing the autopsy, which lasted for more than an hour.

"Zhou Zheng, I have to hand over the forensic report to you. After sending this head to the morgue, I have to sleep for a while." Cui Jun shook his head. He was getting old and couldn't take it anymore.

"Master, do you want to drive back?" Zhou Zheng hesitated and said, "Why don't you take a taxi?"

"I'm not going back." Cui Jun shook his head.

"It's still early, it's completely in time, how comfortable it is to go home and sleep!" Zhou Zheng was stunned for a moment, he didn't pay attention to the time, but according to his feelings, it would not exceed 23 o'clock in the evening, so he could go home and rest.

"Zhou Zheng, this is where your lack of experience is. This is the first time I have seen this kind of murder case where one person created two scenes, but I have seen serial murder cases many times. This type of murderer has a common Features..." Cui Jun put the head into the body bag while speaking, shook his head helplessly and said, "That's just not worrying."

"Master, what do you mean there may be an autopsy tonight?" Zhou Zheng frowned fiercely. He didn't feel that he had done anything, but he just took pictures to report, but he actually went to two scenes and participated in two Anatomy, the exhaustion of energy made him feel tired.

"Didn't you say that the murderer will continue to commit crimes!" Cui Jun looked towards Zhou Zheng.

"It's true from the perspective of criminal psychology, but I can't tell when he will commit the crime." Zhou Zheng said helplessly.

"From the experience of an old forensic doctor, when this kind of serial murder occurs, there is no way to be peaceful in the bureau. Cases often appear in groups, just like people like to join in the fun. I still won't go back tonight. , I have a strong premonition that there will be another case either tonight or tomorrow morning." Cui Jun sighed.

"Master, aren't you a crow's mouth!" Zhou Zheng frowned fiercely again.

"How can you talk to your master!" Cui Jun gave Zhou Zheng an angry look, and said, "This is experience, understand!"

"Understand, understand, experience, experience!" Zhou Zheng nodded repeatedly.

"That's about the same. Don't hang around here. Write the report quickly. If there is a backlog of reports, you will be busy. Even if our forensic department can't help solve the case, we can't hold back." Cui Jun confessed.

"Understood, understood!" Zhou Zheng hurriedly turned around and left the dissecting room, preparing to drive out the forensic doctor's report.

……

Boom!Boom!Boom!
Just as Zhou was sorting out the forensic report at his work station, there was a knock on the door of the forensic center.

Then the door was pushed open.

Feng Yu from the trace inspection department walked in quickly with big strides, his gaze directly focused on Zhou Zheng.

"Zhou Zheng, the DNA test report is out." Feng Yu walked to Zhou Zheng's side with an extremely solemn expression.

"Did you show it to Captain Xia?" Zhou Zheng was taken aback for a moment, but he didn't expect Feng Yu to deliver the report.

"No, I want to show you first." Feng Yu seemed hesitant to speak.

"Is there something wrong?" Zhou Zheng wondered.

"Look..." Feng Yu exhaled helplessly.

"Okay." Zhou Zheng picked up the DNA test report and carefully read the text on it.

A total of four personal material samples were compared in this inspection report.

The three missing female college students, Xu Ruoyang, Xie Yushan, and Han Na, were compared with the No. [-] victim of Doll An, and the results of the comparison were all inconsistent.

That is to say...

None of the three missing persons were victims!
"Captain Xia said that they investigated all the female college students in the city, so they won't be negligent in the current murder case?" Zhou Zheng asked.

"Absolutely not." Feng Yu shook his head.

"That means there is a problem with the detection direction." Zhou Zheng put the report on the table, rubbing his temples with both hands. In fact, in his heart, he already felt that the victim was one of the three missing persons, but DNA comparison It turned out to be a lesson for him.

"Zhou Zheng, that's why I came to you. Do you think it's appropriate for me to give to Team Xia now, or tomorrow morning?" Feng Yu asked.

"We have to face it sooner or later. If this kind of thing procrastinates, it won't change the result. It doesn't make any sense. If you say it earlier, you can change the direction of investigation in time." Zhou Zheng still maintained the movement of kneading his temples, thinking quickly in his heart .

"I think it's quite late today. If I don't say it, the colleagues in the criminal police team can still have a good sleep. I'm afraid I won't be able to sleep well after I talk about it." Feng Yu rubbed her face and said her own concerns.

"It's better not to delay this kind of thing." Zhou Zheng insisted on his opinion.

"Well, okay, then I'll go to Team Xia." Feng Yu nodded. He picked up the report and was just about to leave. After thinking about it, he asked again, "Zhou Zheng, what do you think is wrong? Now that the deceased looks like a college student, could it be that he is a member of society?"

"It's not impossible." Zhou Zheng said in a deep voice. He suddenly felt that there was a layer of fog in front of him, making him unable to see the essence of the matter clearly. I can't raise my hands.

"It seems that you don't have any ideas. This kind of thing is quite unexpected. Team Xia has almost figured out the social relations of the three missing persons, but they can't use it. The case has occurred until now, and even the identity of the victim is unknown." It's hard to be sure, I haven't encountered such a case before." Feng Yu sighed helplessly, with a very obvious remorse on his face, frustrated that he couldn't help.

"There is no way around this. We will try our best to provide more information for the identification of the source of the corpse." Zhou Zheng said in a deep voice.

"Yeah, then I'll go to Team Xia." Feng Yu felt helpless, and he didn't want to see Team Xia and the others' hard work go to waste.

After Feng Yu left, Zhou Zheng was stunned for a moment, then immediately opened the drawer, took out a piece of chocolate, quickly tore open the package and stuffed it into his mouth.

The happiness and joy that sweets provided lingered in his heart, making his brain work faster.

"The deceased was not a female college student?"

Zhou Zheng frowned. He resisted the urge to pull out the file and was busy with the forensic autopsy report in his hand.

There are too few clues available at hand.

Without a complete body, it is difficult to really trace the source of the body. At present, except for Li Yanyan, the city bureau has not received any records of missing persons.

Not only that, but now they haven't even seen the first scene of the crime, so they can't determine the specific nature of the case, and there is no way to explore the basic motive of the murderer.

Both the nature of the case and the motive of committing the crime are extremely important points to ease the detection, but now they are restricted here.

After half an hour.

Zhou Zheng completed the forensic report, and after uploading the electronic version to the case file on the intranet, he began to use a printer to print the physical report.

When Zhou was waiting for the forensic report, he looked in the direction of Cui Jun's desk and found that the latter had fallen asleep lying on the desk.

"Master has worked hard!"

Zhou Zheng sighed silently in his heart, in this day's work, even he, who was only in charge of taking pictures, felt very tired, let alone the master who had to take full responsibility.

The two dissections of the head not only consumed energy, but also consumed extra physical energy. In addition, Li Yanyan could not be contacted, which added a layer of worry to Master's heart.

A fatigue limit has clearly been reached now.

Zhou Zheng picked up the printed forensic report and walked towards the criminal police team of the Municipal Bureau. While walking, he was still thinking, if the two victims were not female college students, what would their identities be?

and many more……

Zhou Zheng stopped suddenly, his eyes glowing brightly.

"We were all deceived by the murderer!"

"Jianghai Normal University was where the body was thrown. It does not mean that the victim was killed at Jianghai Normal University, nor does it mean that the victim is a student of Jianghai Normal University!"

"There is no causal relationship between this!"

"It's just because the murderer arranged the head and dolls in Jianghai Normal University, which aroused a lot of public opinion and caused strong social repercussions. We preconceived that the victim might be related to Jianghai Normal University."

"But if it doesn't matter..."

"Then the murderer's actions have other meanings."

"But……"

"What is the meaning?"

Zhou Zheng frowned tightly. He felt that he was getting closer and closer to the truth. The thick fog had turned into a thin layer. It was as if he could see the contents, but he was still a little short of the last, resulting in blurred vision. cannot see clearly.

"hateful!"

"What the hell is wrong!"

"Who is the murderer and the dead?"

Zhou Zheng felt a strong challenge. This was the first time he encountered such a difficult puzzle after experiencing the case of his parents when he was young.

If such a puzzle appeared in school, he would be very interested. However, this is not a puzzle of words, but a puzzle of life, a blood-stained puzzle woven by the victim.

"Ring-ring--"

Zhou Zheng's thoughts were interrupted by the ringtone of his mobile phone. The moment he heard the ringtone, he subconsciously felt goosebumps.

Just hearing the ringtone gave the feeling that there was a murder.

It's like a death bell, as long as it rings, there will be a case, which makes him uncontrollably have a stress reaction.

He picked up his phone nervously and focused his eyes on the caller ID. The caller was Cui Jun who was still lying on the table and sleeping just now.

"Hey, Master, are you hungry? I'll buy you some supper..." Zhou Zheng said preemptively. The moment he saw Cui Jun's phone call, his brain was filled with an ominous feeling.

"Where are you?" Cui Jun's slightly hoarse voice showed a heavy sense of exhaustion.

"I'm on my way to the criminal police team. I just finished the forensic report and haven't sent it yet." Zhou Zheng felt more ominous in his heart.

"You don't need to go to the criminal police team. Now go back to the forensic center. Let's meet and show up together." Cui Jun's voice became hoarse.

"No, it's coming again?" Zhou Zheng's mouth twitched fiercely, and he couldn't help complaining in his heart, doesn't this murderer sleep at night?

"We have just been called to the police. The reporter said that a black plastic bag was caught on the cross-sea bridge. It was full of minced meat. It looked like chopped human tissue. Because a few fingers were found in the bag, we went to Take a look." Cui Jun's tone sounded very tired.

"Yes, Master, I'll be right back."

Zhou Zheng's heart sank, and after he heard Cui Jun's description, he immediately began to think quickly.

If the inside of the plastic bag is determined to be a corpse, combined with the case currently being investigated...

It is very likely to be the body parts of these two victims!
