Department of Psychology Forensic

Chapter 11 Site Inspection
"It's Changhuwan Community again!"

Zhou Zheng quickly got up from the bed and went straight to the bathroom, just in time to meet Xu Chao who was washing in it.

"Look (early)!" Xu Chao was brushing his teeth, and his articulation was not very clear.

"Let me go first." Zhou Zheng walked directly to the sink without any hesitation, pushed Xu Chao to the side, quickly picked up the toothbrush, and started a quick brush.

"Ah, you, are you in such a hurry?" Xu Chao's mouth was full of toothpaste foam, and he couldn't let go of talking at all, and there was no place to rinse his mouth.

Zhou Zheng didn't pay attention to Xu Chao at all. He finished brushing his teeth as quickly as possible, then put the tooth bucket back on the sink, and quickly ran back to get dressed.

Such a scene made Xu Chao dumbfounded. He returned to the sink and rinsed his mouth to clean up the foam in his mouth.

"Zhou Zheng, why are you in such a hurry!" Xu Chao was a little puzzled, and continued to use his expertise, "If you brush your teeth perfunctorily like you, the residue will corrode the enamel after a long time. , At that time, you will have to come to me to see the dentist, but with our relationship, if you come to me, I will definitely give you a discount."

"There is a murder case." Zhou Zheng said in a gloomy voice.

"Ah?!" The muscles on Xu Chao's face twitched visibly, the coherent brushing movement stopped, his eyelids twitched violently, his lips squirmed slightly, and he swallowed everything he wanted to say.

Boom!

The sound of the dormitory door closing reached Xu Chao's ears. He knew that Zhou Zheng had left, but after hearing the word murder, his mood could not be calmed down for a long time.

"Fortunately, I didn't choose forensic medicine at the beginning. Compared with the smell of corpses, I suddenly feel that the patient's bad breath is nothing..."

Xu Chao started brushing his teeth again, but his movements became less coherent, and he was slowly calming down his mood.

……

After Zhou Zheng left the dormitory, he didn't see the taxi, and then quickly ran towards the gate of the dormitory area.

Generally speaking, if you want to get a taxi in the dormitory area, it depends on your luck. If there is a car to take the students back, you can get a taxi by chance, but in most cases, you still need to take a taxi outside the dormitory area.

Zhou Zheng was anxious, and ran non-stop at a fast pace. After running for 5 minutes, he arrived at the door of the dormitory area. He hurriedly waved to a taxi that was coming. district."

"Okay~" The taxi driver looked in a good mood, kicked the accelerator and set off directly.

……

"Ring-ring--"

Zhou Zheng had just got off the car and was standing at the gate of Changhuwan Community. When he picked up his mobile phone to ask questions, the ringtone happened to be Li Yanyan's call.

"Zhou Zheng, where have you been? I can only wait for you for another 10 minutes at most. If you don't come, you will miss the on-site inspection." Li Yanyan's tone was urgent.

"I'm at the gate of Changhuwan community." Zhou Zheng said, "Then where should I go?"

"Building 2, Room 1701, come quickly and I'll wait for you downstairs." Li Yanyan hung up the phone immediately after speaking.

"call……"

Zhou Zheng's breathing has not yet fully recovered, and he has already realized the importance of exercise that Qin Wangde said.

It's just started now, he hasn't even gone through the entry procedures, and he hasn't seen what the forensic center looks like, so he just appeared on the scene in such a hurry, and he tired himself into this appearance, if it goes on for a long time, his body will It's really easy to overwhelm.

When Zhou Zheng walked downstairs in Building No. 2, he saw Li Yanyan in a white coat from a distance. The latter also wore a pair of rimless glasses, as if she had the feeling of a uniform version of Mr. Fukada .

It's still early, but there are already some onlookers, all talking about the ominousness of the Changhu Bay community.

After all, this is already the second homicide in half a month!
Wang Fan's case was just solved yesterday, and the materials have not been fully summarized yet. The closure of the case has not yet been announced.

In order to prevent the scene from being destroyed, the police in the Changhu Bay area directly pulled the cordon outside Building 2, protecting the scene as much as possible and not allowing entry, but residents of Building 2 are still allowed to go out for normal work.

Li Yanyan took out her ID card to the police guarding the scene, and explained Zhou Zheng's problem, because Cui Jun had explained it earlier, and the police did not stop her.

"There is no time to go to the forensic center when the incident is urgent. I didn't bring you any clothes. You can just use your eyes to inspect the scene. If you find out what you call me, don't move around on your own. I'll let you be careful not to damage the scene." Li Yanyan took out a sealed bag with a piece of blue inside.

"Okay." After Zhou Zheng took it, he took a look and knew that there were disposable masks, hoods, gloves and shoe covers inside to prevent traces of damage to the scene.

"The name of the deceased is Zhao Zhiyong, the owner of Room 2, Building 1701, Changhuwan Community, and the owner of three chain self-catering restaurants in Jianghai City. He is married and has two children. The eldest is a daughter and the second is a son. I work as a teacher in a yoga studio in the urban area, and my two children live with my wife. It was Zhao Zhiyong’s mother, Wang Cuifang, who found the body. She said she had something to look for in the morning and found the body.” Li Yanyan said as she walked. When she entered Building No. 2, she took out an elevator card that she got from somewhere, swiped the card and pressed the button on the 17th floor.

Zhou Zheng listened to the information silently, his eyes were a little dignified, and he didn't know what he was thinking about.

"Hey, why don't you talk?" Li Yanyan stared at Zhou Zheng with blinked eyes.

"What did you say?" Zhou Zheng was stunned for a moment, looking at the ascending elevator, the influence of alcohol was still faintly present, and it had not been completely metabolized.

"Murderer! Portrait! Can you analyze the characteristics of the suspect?" Li Yanyan asked curiously. She purposely inquired about the information with the criminal police team and waited to see Zhou Zheng's performance.

"Criminal psychology portraits are based on evidence, not magic. I don't even know what's going on at the scene, how to make a portrait..." Zhou Zheng's mouth twitched slightly, his face full of helplessness.

"That's it, then..." Li Yanyan was a little disappointed, she really wanted to witness that magical moment, especially when she thought of the inner admiration in the eyes of those criminal policemen at the dinner party last night, for Zhou Zheng became more and more curious.

The elevator stopped on the 17th floor, and the moment the elevator door opened, Zhou Zheng smelled a strong smell of blood.

Such a smell of blood is afraid of bleeding!

Zhou Zheng muttered silently in his heart. Room 1701 is on the left hand side of the elevator, and it has also been cordoned off. He immediately opened the packaging bag of disposable items, and put on the mask, headgear, gloves and shoe covers.

At this moment, Xia Yan came out from the scene with a rather ugly expression on his face, followed by his apprentice Zhao Lei.

"Zhou Zheng, you're here. I have to leave the case to you. I'll go to investigate and have a meeting in the afternoon." Xia Yan said hello to Zhou Zheng and left directly. Now that he is on business, it's not the time for small talk.

"Brother Zhou, you must catch that guy, it's too ruthless!" Zhao Lei said with lingering fear.

"Ah."

Zhou Zheng responded softly. He didn't need to go in to know that the scene was miserable. Such a strong smell of blood is definitely not something that can be done in ordinary murder cases.

Zhou Zheng followed Li Yanyan into the scene. This is a large flat floor with a spacious area. After entering the door, the smell of blood became more intense, and the floor of the living room was already stained red with blood.

A dead body lay in the middle of the pool of blood. His eyes were wide open, his mouth was wide open, his face was slightly desperate, his head was deformed, and his neck was bloody and bloody. It was impossible to see the specific situation.

"Zhou Zheng, come here."

At this moment, a serious voice sounded, and the owner of the voice was Cui Jun.

"Master." Zhou Zheng walked over quickly, paying attention to the blood stains under his feet to avoid stepping on them, and Li Yanyan followed closely behind.

"Some trace inspection colleagues have already taken photos at the scene, and I have also inspected the scene. Now I will give you a chance to see your basic ability and quality. Yanyan has also gone through this kind of assessment, and the delay will not take a few minutes. After Cui Jun explained briefly, he said, "I'll follow you. You come to inspect the scene. If you perform too badly, I will return the goods to Bureau Qin!"

"Okay, Master!" Zhou Zheng felt a burst of pressure and excitement at the same time. He immediately looked in the direction of the corpse and said, "The investigation of a murder scene should focus on the corpse. The first step is to For the corpse inspection, the second step is to inspect the blood at the scene, and the third step is to inspect the items at the scene, then I will start with the corpse first."

After all, Zhou Zheng walked directly towards the corpse, and the strong smell of blood continued to penetrate into his nose through the mask. Even though he was a medical student who had experienced practical courses, compared with the general teacher, the real corpse was still more serious. The impact of the senses, from sight to smell, uncontrollably mobilizes psychological and physical discomfort.

Cui Jun nodded silently and did not speak, he was assessing Zhou Zheng's ability in his heart.

The blood at the scene soaked the entire floor of the living room. Zhou Zheng's eyes moved, and his eyes fell on the inspection box brought by Cui Jun.

"Master, can I use the contents here?" Zhou Zheng asked.

"Use it whatever you want." Cui Jun further evaluated Zhou Zheng in his heart, at least this is not a stunned young man, and he is not reckless in thinking.

"Thank you, Master." Zhou Zheng opened the bottom of the inspection box, and took out an inspection pedal from it. There were traces of the latest cleaning on it. It was obvious that it had been used not long ago. After laying down the inspection pedal, he approached the corpse.

Seeing such a scene, Cui Jun nodded silently, didn't say much, and didn't approach the corpse, but stood in place and observed Zhou Zheng's on-site inspection.

"The deceased was lying on the ground with a deformed head and obvious marks of being hit by a blunt instrument. There were multiple cuts on the neck. No murder weapon was found at the scene. The blood on the ground was too thick to identify whether there were signs of a fight." Zhou Zheng said slowly that he was strictly following the on-site inspection steps, first judging the relationship between the state of the corpse and the traces and objects on the scene.

"The deceased was wearing a black suit with a shirt inside, a tie that had not been untied, and no slippers on his feet. The clothes were relatively intact, but..." Zhou was frowning suddenly when he was inspecting the clothing of the deceased, and said: "The clothes of the deceased seem to be in good condition, but there are traces of being rummaged through. There should be some missing items. Master, I didn't find his wallet."

"The wallet and documents are gone." The expression on Cui Jun's face softened a lot, and he asked, "How did you see that?"

"The deceased was lying in a pool of blood. The clothes on the back were stained with a large amount of blood, but the front was only splattered with blood. The wound on the neck had obvious life reactions. Both carotid arteries and jugular veins, as well as the trachea and esophagus were all intact It was cut off, indicating that the deceased was hacked to death in this lying position, and had lost his ability to move before that. Apart from splatter-like blood stains, there were rubbing-like marks on the white shirt inside the suit. The bloodstains, this shows that the murderer sorted out the deceased's clothes, so I speculate that the murderer rummaged through the deceased's things, most likely the wallet, and..." Zhou Zheng frowned again, and said: "Mobile phone!"

"That's right, the deceased's mobile phone is gone." Cui Jun was very satisfied with Zhou Zheng's performance.

Zhou Zheng took out the ruler from the inspection box and began to measure the corpse in all directions. Then he took out the thermometer, unbuttoned his trousers, and stuffed it into the rectum.

"The deceased had a huge amount of bleeding, the spots on the corpse were light, the rigor had not yet formed in the large joints, and the cornea had not yet started to become cloudy. It should not have been long since he died, maybe five or six hours ago, and the exact time has to wait for the thermometer to check The result." Zhou Zheng put away the ruler and continued: "The deceased was 188cm tall, with a strong build and a strong physique. There was no abnormality in the body. The details of the scars on the corpse need to be taken back for further autopsy."

"The autopsy was done very well!" Cui Jun praised without hesitation. Even an old forensic doctor like him can only find so much information from the corpse table.

"The next step is the on-site inspection..." Zhou Zheng began to prepare to observe the scene.

"There is no need to inspect the scene. The colleagues of the trace inspection have inspected it. They have already left, and there are no valuable traces." Cui Jun said.

"Master, you are testing me. I understand that the most important thing for a forensic doctor is not to have preconceived notions. You must make a test yourself to draw a conclusion, otherwise you may miss valuable traces due to omissions or illusions."

Cui Jun was stunned. He really wasn't testing Zhou Zheng, but thought that the autopsy was good enough for the autopsy, but he didn't think that Zhou Zheng had misunderstood it.

"Let me see how you do it!"

Zhou Zheng's eyes became sharper. For him, inspecting the scene is not only to collect effective trace evidence, but also a necessary step to probe the murderer's heart.

The crime scene is the work of the perpetrator, the victim is one part, and the crime scene is the other part.

"As long as the murderer has been to the crime scene, there will be traces. No matter how careful and thorough the cleaning is, at least psychological traces will be left. The behavior can be reflected through the phenomenon, and the psychology can be reflected according to the behavior. Regardless of whether the murderer No matter how the scene is disguised, he won't be able to escape!"

Zhou Zheng muttered silently in his heart, and then began to inspect the scene meticulously and focusedly, looking for useful information as much as possible.
