Department of Psychology Forensic

Chapter 137 Clues
Cui Jun squatted down, took out the rectal thermometer from the corpse, and looked at the reading on it.

"29 degree!"

Cui Jun paused, and said: "Agreed with the temperature, the death time is at least 10 hours or more."

In spring and autumn, within 10 hours of death, the temperature of the dead body drops by an average of 1 degree per hour, and after 10 hours, it drops by 0.5 degrees per hour until it reaches the same temperature as the environment.

It is summer now, and the speed of corpse cold has eased, which is 0.7 times that of spring and autumn, that is, in the first 10 hours, it has dropped by 0.7 degrees per hour.

In winter, the body cools faster, 1.4 times that of spring and autumn.

The current ambient temperature is 29 degrees, and the body temperature of the corpse drops by 0.7 degrees per hour, and it takes 10 hours for the body temperature to drop by 7 degrees, so the deceased has died for at least 10 hours.

However, in this way, the judgment through the temperature of the corpse will lose its meaning.

Because when the temperature of the corpse is lowered to be consistent with the environment, the phenomenon of hypothermia will stop.

If you want to determine the specific time interval of death, you need to determine it through other post-mortem changes.

Immediately afterwards, Cui Jun picked at the dead man's eyelids and looked at the eyeballs.

"The cornea is cloudy and translucent, and the pupil can be seen vaguely. It is in a moderately cloudy state. The death time is more than 15 hours, but within 24 hours."

Cui Jun refreshed the range of the time of death again, and then swung the old lady's arm, with a little force, the whole body was tilted up.

"The rigor reached the point where the joints of the whole body were stiff, and the death time was about 15 hours."

After turning the body over, he lifted the clothes and looked at the skin.

Pieces of dark purple-red corpse spots suddenly appeared in everyone's sight.

Cui Jun pressed his finger on the corpse spot, the color of the corpse spot faded, and after releasing it, the corpse spot recovered.

"Diffusion stage corpse plaque, death time is between 12 hours and 24 hours."

Say it.

Cui Jun raised his left hand, looked at the watch on his wrist, and said, "The time of death of the deceased was between 12 and 15 hours, and it is now 17:2 in the afternoon, so the specific time of death of the deceased should be from 5:[-] to [-]:[-] this morning." between points."

Cui Jun immediately gave the range of the time of death. After determining the time of death, the subsequent work of the criminal police will be much easier.

17 points!
After hearing what Master said, Zhou Zheng suddenly thought of something. He picked up his phone and saw three missed calls, and there were still seven unread messages on WeChat.

Oops!

Zhou Zheng suddenly realized that he had forgotten about Zhang Ying. The sudden murder case attracted all his attention.

He quickly picked up his phone and looked over. The three missed calls were all from Zhang Ying. Then he opened WeChat, saw the number on the portrait of the kitten, and clicked on the dialog box.

【I have arrived】

[I'm here, when do you leave work? 】

[? ? ? ? ?Where are you! 】

【Zhou Zheng, what do you mean by not answering the phone? 】

[You did it on purpose, right! 】

[Why don't you answer the phone? 】

[Wait no more, I'm leaving, don't look for me, goodbye! 】

When Zhou Zheng saw the last part, his eyelids twitched violently. He still knew the character of this younger sister quite well.

The on-site survey was almost done, he put the camera away and put it in the survey box.

"Team Xia."

Zhou Zheng quickly walked towards Xia Yan who was next to him, lowered his voice, and said, "Captain Xia, help master with the body. I have some private matters, so I need to call back."

"Well, you can go." Xia Yan nodded, it's not a big deal, they always help each other.

"Thank you!"

Zhou Zheng picked up his mobile phone and walked towards the side of the unfinished building, a big question mark popped up in his mind.

what happened?

Why didn't I hear the vibration?

He looked at the time when the call came in again, and pushed back a little. At that time, he was climbing the stairs.

Understood!
Zhou Zheng immediately had the answer. To climb the stairs, he had to take this unfenced staircase. At that time, he was too focused, and his mobile phone was in his trouser pocket. Maybe he took it as wind.

Pick up the phone and dial Zhang Ying's number.

"beep--"

Just after the sound, an electronic tone sounded instantly, "Sorry, the number you dialed is temporarily unavailable, please dial later."

The corners of Zhou Zheng's mouth curled up slightly. He knew what this sister was thinking too well, so he immediately hung up the phone and dialed again.

"Sorry, the number you dialed is temporarily unavailable, please try again later."

Zhou Zheng hung up the second time and started dialing again.

"Sorry, the number you dialed is temporarily unavailable, please try again later."

"..."

Zhou Zheng took the trouble to call over and over again, even he himself didn't know how many times he had dialed, and finally, the phone was connected.

"What are you doing?" A female voice who was obviously still angry sounded, and the owner of the voice was Zhang Ying.

"I didn't mean not to contact you. A homicide happened. I'm at the scene." Zhou Zheng explained, he understands the character of this sister, and he needs to pay special attention to it. It doesn't matter if she jokes at ordinary times. If she is angry, there is only one way to calm her down. It's just stalking.

The stalking here doesn't mean to be annoying, but that's what Zhang Ying does.

According to the experience Zhou Zheng summed up, he felt that every time Zhang Ying got angry, she was waiting to be coaxed, as long as she kept coaxing, even though she hung up the phone over and over again, she felt very happy.

The moment the call was connected, it meant that he had calmed down and was not far away from being coaxed.

"Has there been a murder case?" Zhang Ying regained her spirits all of a sudden, and the tone of blame was gone.

"Yes, the incident happened suddenly, and I didn't have time to say hello to you. I have to work overtime now, and I don't know when I will get off work. Why don't you go home first, and I'll treat you to hot pot next time." Zhou Zheng wasn't fooling around, But the moment the murder happened, everything else gave way, and he only remembered it afterwards.

"Two meals!" Zhang Ying said stubbornly.

"Three meals." Zhou Zheng said.

"Hahahahaha, okay, then I'll go home directly." Zhang Ying immediately laughed out loud.

Zhou Zheng hung up the phone, knowing that this matter was considered a turning point, but he just overdrawn the future and saved three meals for the future.

"gone back!"

At this moment, Cui Jun's voice sounded in the distance, and Zhou Zheng immediately turned around and followed.

……

Municipal Bureau, small conference room.

Ma Yan and Qin Wangde were wearing neat uniforms, standing in the room, and there was another person opposite them.

"Director Wen, why are you here in person!" Ma Yan greeted with a serious face.

"The recent case in Jianghai City has attracted the attention of the higher authorities. The provincial department must come to inspect the work." Looking up at the age of more than 50 years old, his face is covered with wrinkles, but he is quite upright, saying: "If you have any difficulties, just mention it, as long as I can do it, I am obliged to do so."

"Director Wen, it's not that we don't solve the case, but that the complexity of this case exceeds our imagination. Not long ago, another body was found on the abandoned unfinished building at the intersection of the highway, and it was related to the serial case." Qin Wangde said.

"Lao Ma, Lao Qin, we haven't known each other for a day or two. You know my personality very well, and I won't be here to mess with you. Let me be blunt. The Provincial Department hopes that you can solve the case within 3 days." Chang's face suddenly became serious, and a strong official authority appeared on that wrinkled face, saying: "If you have any difficulties, we will do our best to cooperate. This case cannot be dragged on any longer. Not only the social impact It's bad, and even the people above are a little dissatisfied."

"Three days is a bit tight." Ma Yan looked distressed. He followed these cases all the way, and he knew the difficulties very well, so he wanted to buy a little more time.

However, before he could speak, his words were pressed back into his stomach.

"Old Ma, it's useless for you to tell me these things. I didn't bring it up. If the case is not solved after 3 days, I won't be the one who comes to drink tea with you again." The director of Wen shook his head and said. .

"Hey... I understand." Ma Yan sighed heavily, and suddenly felt like he was carrying two big mountains on his shoulders, and he couldn't breathe under the pressure.

"Well, Director Wen, it's late at night, let's go out to have a bite, Lao Ma treats you." Qin Wangde suggested.

"Yes, yes, please, please." Ma Yan nodded again and again, knowing that Qin Wangde was cooperating with him, and he could try to buy some time during the meal.

"I won't eat the meal. There is a meeting with the mayor. I have to go there, and then I will go back. You should focus on solving the case." Director Wen suddenly paused when he said this. Suddenly, he looked at Ma Yan meaningfully, and said, "Mom, how long have you been sitting in the director's seat?"

"Four years." Ma Yan's heart trembled, and he realized something faintly.

"It's almost been five years!" The director of literature nodded, turned to look at Qin Wangde, and asked, "Old Qin, what about you?"

"I was transferred with Lao Ma," Qin Wangde replied.

"It is said in the Tao Te Ching that good fortune is where misfortune depends, and misfortune is where good fortune rests." The Director of Wen said flatly, "Your term of office is almost up. If this case is not handled well, what will happen to you? You can guess it, but if the case is done beautifully, I won’t say anything later, you can understand.”

For a moment, there was a silence at the scene, and no one spoke.

……

Forensic Center.

Zhou Zheng and Cui Jun finished the autopsy overnight. The signs of death of the deceased were too obvious. There was no dispute about the cause of death. It was mechanical asphyxiation caused by strangulation. Apart from restraint wounds, there were some other abrasions on the body, which were not particularly serious. Obviously, it should be left by struggling in pain.

The deceased's blood samples and visceral sections have been sent to the laboratory.

Zhou is making a forensic report at a fast pace. After finishing this, he will write an application for merger.

……

An hour later, at 8:20 p.m.

City Bureau, Interpol.

Everyone gathered here to hold a special meeting on the tooth extraction case.

Ma Yan and Qin Wangde were also present.

"Zhou Zheng, tell me." Cui Jun patted Zhou Zheng's shoulder encouragingly, and said with a smile, "You have to practice."

It's so sudden!
Zhou Zheng was not mentally prepared for this at all.

However, he followed this case closely, so there was nothing he couldn't say, so he nodded immediately.

"Okay, Master." Zhou Zheng replied.

After a while, Ma Yan got up and came to the front of the stage. His actions made the scene quiet immediately, and all eyes were fixed on him.

"Before the project meeting starts, I have something to tell you."

Ma Yan glanced at everyone at the scene, and stayed on everyone's face for a while, making everyone feel the feeling of being watched.

"The head of the Ministry of Culture came tonight and passed on the latest instructions to us."

Having said that, he stretched out two fingers, and continued to speak under the suspicious gaze of everyone.

"2 days! The provincial government has given us 2 days to solve the case!"

ho-

The scene suddenly exploded, whispering voices sounded, and everyone's face had incredible expressions.

Those who can hold a special case meeting here are those who follow up the case. Everyone knows very well that for a case like this where the scope of suspects has not been finalized, it will take two weeks, let alone two days. It may not be broken.

"Horse Bureau, isn't this time too tight?" Xia Yan's face was full of bitterness, this case is really not that easy to solve, and it's not a rush for homework, two days is not enough!

"Don't be too small. I have won this for you. When the director of the department came, he told you to solve the case tomorrow, and the others will not leave. Waiting for the result of solving the case tomorrow, I am worried that you will be under pressure. Let Director Wen go back first, and get another day, so 2 days is the limit, and the case must be solved!" Ma Yan said solemnly, he did not say that Director Wen gave 3 days, so if the time is up, , there is no room at all, and if it is said that it is 2 days, if the time is too late, you can accommodate one day.

Immediately, everyone at the scene felt Alexander.

"The project will start. Please quickly report the phased results. I heard that you are going to merge the case. Let me hear the basis for the merger." After Ma Yan finished speaking, he returned to his chair and left this place for the Everyone.

Xia Yan walked up directly, his face was a bit ugly, the request to solve the case within 2 days brought him great pressure.

"Let's talk about the information about the deceased in the unfinished building case first."

Xia Yan picked up a piece of printed paper and looked at the information on it. At the same time, the big screen behind him simultaneously displayed the content on it.

"The name of the deceased is Cao Guifang, female, 72 years old. She used to be a teacher at Zhonghua Road Primary School in Jianghai City. She has retired for many years. Her wife died early and she lived alone. He has a son named Cao Yuan who works in other places. We have notified the situation. Him." Xia Yan said.

"How is the social relationship of the deceased?" Ma Yan asked immediately.

I was just about to say it!

Xia Yan complained silently in his heart, faintly felt that the horse bureau was a little anxious today, and it didn't look like it was sitting on a mountain like it used to hold special project meetings.

"The old lady's social relationship is very simple. There are only a few friends who dance square dances in the community at night. Since she is the head teacher of the primary school, no students usually come to see her. After preliminary investigations, no enemies were found."

After Xia Yan finished speaking, the faces of everyone at the scene became even uglier.

Again no idea.

Let alone solving the case in two days, whether it can be solved is a question.

"but……"

Xia Yan paused suddenly, changed the topic, and said, "I discovered an interesting phenomenon, I don't know if it's a coincidence, Zhang Xin once taught in Zhonghua Road Primary School, but only for a year."

Zhonghua Road Primary School!
Zhou Zheng's eyes widened suddenly, and his pupils contracted violently, remembering this clue.

This is the only place where the two victims can be connected so far!
