Department of Psychology Forensic

Chapter 112 Laterally Impacted Wisdom Teeth
When Zhou Zheng returned to the dormitory, it was already very late. He chatted with Professor Fan for a long time in Professor Fan's office, especially about Gao Sheng's case, and gained a lot.

Gradually, he realized one thing. During the forensic examination, he put himself in the perspective of the investigation, but from the perspective of the criminal psychologist, it was the perspective of the murderer. This is a completely different situation.

In fact, he was very clear about this kind of truth in the past, but after being involved in a case, it is very easy to get lost.

"Squeak-"

Zhou Zheng pushed open the door of the dormitory, dragged his tired body, walked in and sat on a chair, looked at the laptop on the table, wanted to open it, but didn't know what to do after opening it.

"I came back so early today!" A suspicious voice sounded from the door, it was his roommate Xu Chao.

Xu Chao carried a bag of pears, brought them in, put them on the table, thought for a while, and asked, "Do you want to eat pears?"

"No." Zhou Zheng shook his head.

"I knew you would say that." Xu Chao still picked up two pears and said with a smile, "I'll wash one for you."

After that, he turned and left the dormitory, and after a while, he came back with two wet pears, and put one of them on Zhou Zheng's desk.

"Thank you." Zhou Zheng was not polite, picked up the pear and ate it.

"Is there no case recently?" Xu Chao asked curiously while biting a pear.

"Yes, but I don't have a clue." Zhou Zheng said absent-mindedly. He was still thinking about how to balance the balance between forensic identification and criminal psychological profiling. In theory, he felt that forensic identification could help judge the criminal's psychology more easily. , However, in the process of identification, question marks will continue to fill his mind, making it difficult to detach himself from the case and examine the criminal's heart.

"Is the work of your forensic doctor exciting?" Xu Chao said with a face full of curiosity: "When I filled out the volunteer application, I saw the forensic major. That, don't get me wrong, I am not going to apply for the forensic exam. What kind of students apply for this unpopular major."

"Compared with dentists, forensic doctors are indeed less popular." Zhou Zheng nodded and said pertinently.

"It's more than that!" Xu Chao took out his hand, drew a line in the air, and said, "The income curve of ordinary doctors is like this..."

When he spoke, his fingers stretched forward in parallel, like a death line without a heartbeat.

It goes without saying that the horizontal axis is age and the vertical axis is income.

When Xu Chao pulled his finger to a certain distance, he suddenly raised his finger upwards, and the movement was very exaggerated.

"This is the income curve of ordinary medical students. When they first enter the job, their income is not high, and it will not change for many years. However, when their qualifications increase, their remuneration will rise in a straight line. This is a long-term accumulation. Jobs with seniority, the older they are, the more popular they are!"

Xu Chao obviously has a lot of research on the income of medical students after graduation. After he finished speaking, he returned his finger to the original point.

"We dentists do it the other way around."

Xu Chao put his finger in a middle position at the beginning, then went straight up, and when he reached the highest point, he dropped quickly.

"Dentists can start working after the internship period. In a very short period of time, they can achieve a continuous increase in income and reach the peak when they are around 40 years old. However, after that, it will not be so wonderful. It can be said that it is unknown in old age. Ah!" Xu Chao exclaimed.

"What an unfortunate old age, you've become a red-haired monster." Zhou Zheng said curiously.

"This is the reality." Xu Chao said seriously: "Dentists' income is increasing faster than ordinary doctors. They are on the job almost every day, either treating teeth or on the way to treat teeth. What they eat is a bowl of youthful rice. When I get older, I won’t have rich qualifications like other doctors. Instead, I’m more powerless. I’ve made a plan. First, I’ll make a lot of money for a few years, and then I’ll open a dental clinic and recruit other dentists to work. I can lie down and make money."

"Good guy, you still have career plans..." Zhou Zheng said with a smile while chewing on a pear.

"That's necessary! Every profession must have a plan! But you, do you know the income curve of forensic medicine?" Xu Chao put his finger directly at the lowest point, and then pulled it all the way to the end, saying: "See No, that’s it, there is no improvement at all, what I hold is an iron rice bowl, I can’t get a golden rice bowl or a silver rice bowl in this life, what I want to focus on is a stable, stable poor.”

"Not all industries are measured by money." Zhou Zheng sighed.

"That's what you say, but if you don't have money, who do you talk to about your ideals!" Xu Chao shook his head and said, "After the college entrance examination, when I applied for the exam, I studied which doctor made the most money, but how should I say it?" , In fact, there is a kind of doctor who is the most profitable, but the employment environment in our country is very, very, very poor, that is the psychiatrist, think about it, people you know, has anyone seen that thing!"

"What you said seems to have been taken over by me." Zhou Zheng gave a wry smile helplessly.

"Don't touch porcelain!" Xu Chao took a bite of a pear and continued: "You are not a psychiatrist, you are studying criminal psychology, and you study abnormal criminals and perverts. There is no way to treat ordinary psychological problems with this kind of thing, you have to study criminals."

"You understand quite well!" Zhou Zheng suddenly felt that his roommate didn't look like a happy little girl in his performance, and he was quite planning in his heart.

"That must be!" Xu Chao continued to eat pears, staring at Zhou Zheng with curious eyes, and said, "Well, tell me about the work of forensic medicine, I am so curious, every day What does it feel like to touch a dead body?"

"Speaking of corpses..." Zhou Zheng seemed to realize something suddenly, looked at Zhao Lei immediately, and said, "We dissected a corpse, and there was a long incision on her left rear molar, and there was gelatin sponge inside. It should have died shortly after the wisdom teeth were pulled out, I remember you said you had the wisdom teeth pulled out, tell me what happened."

"No way, brother, you have found me in the case, and I have an occupational disease within a few days of the internship!" Xu Chao showed an extremely exaggerated expression on his face, and then returned to normal, frowning slightly, and said: "You said that you will get sick later!" Tooth with a long cut?"

"Yes." Zhou Zheng nodded.

"How long?" Xu Chao continued to ask.

"About 4-5cm." Zhou Zheng replied.

"Horizontal impacted wisdom teeth!" Xu Chao's pupils shrank suddenly, and said: "The horizontal impacted wisdom teeth should be extracted in such an incision. This was my first surgery. It was very difficult. I was sweating all over the time." , the wisdom teeth of this type of patients grow horizontally and will push against the molars to cause dental caries. This type of wisdom teeth often grows in an improper position in the jawbone and hides in the gums and cannot come out. Therefore, the gums need to be cut before extraction, and then removed. The teeth were smashed and taken out."

"Are you sure?" Zhou Zheng frowned slightly. He didn't know much about dental medicine, and many terms were only conceptual.

"It's about the same. At least I think that if the wisdom teeth are not horizontally impacted, there is no need to cut the gums with a knife. After the anesthesia is administered, the extraction can be done directly." Xu Chao thought for a while and said.

"Wait, let me think about it, that morning you said that you were going to have an operation, at that time..." Zhou Zheng pinched his chin and replied, that day happened to be the time when Zhao Zhiyong's case happened, that is, after that day , the case of throwing the corpse across the sea bridge happened, and then he stared at Xu Chao and asked, "Has the patient you pulled out the tooth ever had a follow-up visit? What kind of physical characteristics does he have? Do you still remember his name?"

"No, are you really investigating me?" The corner of Xu Chao's mouth twitched fiercely.

"Do you remember?" Zhou Zheng asked solemnly.

"Remember." Perhaps because of Zhou Zheng's exclamation, Xu Chao put away his expression, and his whole person became dignified, and said, "I'll tell you, it's me. Ask another dentist, who can remember this thing?" , How many patients are treated every day, but I only remember that one, who made her the first time, I mean, the first operation!"

Many people will never forget the first time, or say, it is difficult to forget.

No one can really forget it!
The same is true for doctors. Many first times will be imprinted in memory.

The first patient to be seen, the first patient to be operated on, the first case to be diagnosed, and so on.

As for the forensic doctor... it was the first corpse to be dissected.

"How many times have you had your impacted lateral wisdom teeth extracted?" Zhou Zheng asked.

"That's just one!" Xu Chao stretched out a finger and gestured.

"It's okay, just remember this. Tell me, name, gender, age, appearance, clothing, etc., as long as you can think of it, you can say it." Zhou Zheng stared at Xu Chao closely, his heart He didn't have too much expectation, but now that he's said this, he decided it's better to ask.

"Ring-ring--"

However, at this moment, Zhou Zheng's cell phone rang, interrupting the conversation between the two of them.

Zhou Zheng quickly took out his mobile phone from his pocket as if he had been electrocuted, and looked at the caller ID. The caller was none other than Xia Yan.

"wait for me a while."

Zhou Zheng gave Xu Chao a look, then walked out of the dormitory with the phone in his hand, and went straight to the end of the corridor.

Seeing Zhou Zheng's disappearing back, Xu Chao twitched his lips and said, "Fortunately, I didn't choose a forensic doctor. Let alone fishing, there's no time to get off work."

……

"Captain Xia, what's the situation?" Zhou Zheng tried his best to make his voice appear calm. In just a few days, he had already developed a stress reaction to the phone ringing.

"Where are you?" Xia Yan didn't answer, but asked directly.

"I'm at school." Zhou Zheng replied.

"Wait for me, I'll pick you up." Xia Yan said forcefully.

"Could something be wrong?" Zhou Zheng suddenly had an ominous feeling in his heart.

"Yes, a male body was found in the Huimin community. Doctor Cui's appraisal at the zoo has not yet finished. He wants you to do the on-site appraisal." Xia Yan replied.

"Sure enough, there is another murder case!" Zhou Zheng sighed.

"You come out of the dormitory and walk to the door of the dormitory area. I'll come to pick you up right away. It's just on my way so I won't delay you." Xia Yan finished speaking and was about to hang up the phone.

"Wait!" At this moment, Zhou Zheng suddenly thought of the conversation he had just had with Xu Chao, and said, "Captain Xia, I was just looking for you, and I made a new discovery. The last thing we did was to extract the lateral impacted wisdom tooth on the lower left side, and we can narrow the scope a little more during the investigation.”

"Okay, I'll tell them now, is there anything else?" Xia Yan asked.

"Gone."

"Then I'll hang up." As soon as Xia Yan finished speaking, a busy tone rang from the phone.

"call……"

Zhou Zheng took a deep breath, propped up his chest, and after two seconds, slowly exhaled, trying to calm down his mood.

It's time to come!
He knew very well in his heart that he was working as a forensic doctor, and he was still in the city bureau. He was notified of almost all murder cases in the city.

He didn't want to hear the ringtone of the phone, and didn't want to see any of the victims killed, but these things didn't change according to his will.

All he can do is to find out the murderer as much as possible, no matter what method is used, the method of forensic science, or the method of psychology.

"Yes!"

Zhou Zheng's eyes lit up suddenly, and the problem that was bothering him was suddenly solved.

"Methods are dead, but people are alive. Not all cases are suitable for solving cases with forensic evidence. On the contrary, not all cases are suitable for using criminal psychology methods."

"According to the phenomenon presented in the case, use the appropriate method, this is the most effective!"

"As the saying goes, a black cat and a white cat are good if they can catch mice. As long as I can find the murderer, then the method I use is a good one."

"No matter what method the ultimate goal is to find the murderer, I will not give up on forensic identification and criminal psychology without overwhelming my skills!"

Zhou Zheng thought a lot at this moment. In fact, not all cases are suitable for criminal psychology. He was minoring in this subject at the time, and he also wanted to make a supplement on the basis of forensic identification.

It was true that Professor Fan had flattered him, and taught him everything as an apprentice, which made him a little uncertain.

In fact, Zhou Zheng also understood that it was difficult for him to reject Professor Fan, not because he cared so much about criminal psychology, but because he didn't want to see Professor Fan disappointed.

After thinking about it, he returned to the dormitory, glanced at the unheated chair, picked up the half pear left on the table, turned and walked out.

"Zhou Zheng, why are you going?" Xu Chao was a little dumbfounded. How could this man half-talk and leave as soon as he said it, how uncomfortable it was.

"There is a case." Zhou Zheng said lightly.

"What about my story?" While waiting, Xu Chao tried hard to recall all the details of the first operation.

"I'll listen when I come back." Zhou Zheng dropped a sentence and went downstairs quickly. He calculated his speed, and now he walked faster. When he reached the gate of the dormitory area, Xia Yan's car would arrive.
