I don't want to solve the case when I'm a little policeman.

Chapter 663
After the meeting, Xu Zheng first went to the Forensic Medicine Department of Changming University Medical College. Professor Ji Dongli had a class today.

In Professor Ji's office, after the teachers and students sat down, Xu Zheng directly explained the purpose of his visit, "Teacher, my immediate boss, his mother-in-law is suspected of having a tumor. She is now in the provincial hospital. Please help me say hello to Dean Zheng. I'm looking for you." Let an expert take a look."

Ji Dongli's gray brows raised, and he said strangely: "Tumor, if you want to talk about this disease, you don't have to go to Lao Zheng. He owes you a favor, and he is using it for this purpose. I am good friends with Professor Ni from the Oncology Department of the Provincial Hospital." .

Just go to him directly.

I will call him later, and I will send you his contact information later. You can ask your leader to contact him directly when he arrives at the provincial hospital. "

Xu Zheng looked grateful, "Thank you, teacher. This time we went to Shanghai to capture a Class A wanted criminal. Her method of committing the crime was to use genetic drugs to induce and aggravate the victim's cancer. After this news came back, we will organize a fugitive investigation." Many leaders took the time to do a comprehensive physical examination.

Teacher, you and your wife should do this once you have time. There are some cancers that may not be detected until later physical examinations. "

"Hi! I have heard a little about what you are talking about." Ji Dongli fell into deep thought, "Actually, the synthesis of this kind of genetic medicine is not difficult. There is even a process on the Internet. What is more difficult is the raw materials.

Therefore, if you want to supervise this kind of criminal behavior, you have to start from the source, such as the research institutes of major hospitals and schools.”

Professor Ji talked a lot about this type of criminal behavior, and the case was explained in detail. Xu Zheng listened carefully to the teacher's teachings and admired his knowledge reserve. However, he still had a task to attend to today, so he chatted with the teacher for a while. He said goodbye.

"Teacher, I have to go to the Yuhuatai branch later to help them capture a fugitive."

"Is he the man who killed his wife's lover?" Ji Dongli returned to the computer, opened an email, and waved Xu Zheng over to take a look, "This is the autopsy report sent by Xiao Lu from the city bureau.

how to say?

He invited me over and said that they had dissected the body and found that the skull of the deceased, that is, the wound on the back of the head, was in the shape of broken bones, and that the two blows were on the same spot. "

Ji Dongli pointed to the two photos of wounds and analyzed: "Look at the first photo, the murderer probably hit the back of the deceased's head with a stick at home, and the front part of the stick hit the top of the skull.

The wound was in an up and down shape, and the fatal cause was that the skull was broken and the brain was shattered.

The second photo shows that although the wound is in the same location, it is a little bit below the first wound. It also has an up-and-down shape, but it is obviously larger and deeper than the broken bones in the first photo.

Of course, it is also possible that the wounds in the second photo were caused by the murderer's first blow.

You are now a criminal investigation expert. What does this mean? "

Xu Zheng stared at the two photos and fell into deep thought, and the expression on his face solidified, "Generally speaking, the murderer finds his wife's lover doing things in his bed. In a rage, he takes his grip stick and attacks his lover. A blow to the back of the head.

This was a strike with anger, and his strength must have been used with all his strength.

In the second photo, it can be seen that the murderer's second blow not only hit the same wound, but also the two wounds were close to each other. When a person was angry, he used all his strength, but he couldn't grasp the direction of the blow. .

Just like when we chop bones, the second and first cuts have only a [-]% chance of being cut at the same location under strong force.

Considering that the murderer was angry, I have a feeling that these two wounds may not have been caused by the same person. "

Ji Dongli nodded and added: "Your and Xiao Lu's analysis is similar, except that we can't do experiments on such bone-shaped wounds, but according to my experience, these two photos, two wounds.

It can be shown that this was indeed done by two people.

Because of a wound of this magnitude, if the deceased only received one blow, there is a [-]% chance that it would not cause death, but there is also a [-]% chance of causing a concussion.

If you take two blows, you will really die.

And if you look at this second photo, although the wound partially overlaps with the first one, it is fragmented and shallow at the bottom and deep at the top, indicating that the murderer probably hit the deceased while he was lying down.

The wounds on the first photo were deep at the bottom and shallow at the top, indicating that the murderer struck him while he was standing. "

That's why I said there were two murderers, because if the first blow knocked the deceased to the ground, then it was impossible for him to squat on the ground with the second blow and specifically aim at the position of the first stick and strike again. "

"Teacher, I can't analyze what you're talking about from the wound. It seems that you have rich experience." Xu Zheng told the truth, the difference between the two wounds is not very big. Without many years of experience, I can't analyze it. The intensity and angle of the hit.

Ji Dongli shook his head slightly, "I have been a forensic doctor for many years. When you reach my age, you will be able to see it. However, this is just a photo. The real situation requires you to personally examine the head of the deceased.

As forensic doctors, we can't just use our eyes to see and use instruments to analyze. We also have to touch with our hands and analyze with our brains. We even have to use physics to analyze force and psychology to analyze the murderer's mental state at the time of the crime. "

Xu Zheng listened and took notes carefully. This is experience. Forensics must be cautious. "Teacher, it's not too late. Let's go to the city bureau to find Forensic Doctor Lu now."

Ji Dongli looked at his watch and shook his head, "I have a very important meeting in the afternoon. I will go to Xiao Lu's place at four o'clock. Since the forensic doctors have different opinions, you can take advantage of this time and go first See it live.

Come on, let me help you simulate what happened. "

As he spoke, Ji Dongli picked up a newspaper and rolled it into a paper stick. He first asked Xu Zheng to stand up and hit him on the back of the head with the stick. The position is filled with one more stick.

"This is probably the case. Go to the scene and see if you can find any relevant clues. I think there are at least two murderers in this case. One is the man you are chasing, and the second is probably a man, who is stronger. More powerful.

He probably took advantage of the man's escape and entered the room with the door open. When he arrived at the scene, he found that the deceased was still alive and the woman was in a coma, so he picked up the grip stick and hit the deceased on the head who was already lying on the ground. "

"Teacher, I think the course of the case should be the same as the result of your reasoning. Your forensic case handling ability is better than that of us investigators." Xu Zheng looked in admiration and began to flatter him.

Ji Dongli smiled slightly, "Forensic doctors are also criminal police officers, and forensic doctors have first-hand access to the autopsy reports of the deceased. Therefore, you cannot underestimate the role of our forensic doctors in criminal investigation. You must pay attention to it."

"Well, teacher, you are right. I will continue to skip classes in the future, right?" Ji Dongli interrupted Xu Zheng and said with a smile: "Forget it, you are quite busy at work, Xiaorui. It's almost time to give birth, and you have to spend time at home. After you're busy for a while, you have to catch up on your classes."

Xu Zheng quickly promised, "What you're teaching me is that I will take time to take classes in the future, hehe. Fortunately, I came to your place first, otherwise I would have gone directly to Yuhuatai, and I would definitely not have found any useful clues."

Hearing this, Ji Dongli reminded him with a serious face: "You have the wrong mentality. You can't investigate the scene with the idea of ​​two suspects. Instead, you must infer the true incident of the crime based on the situation at the scene.

There can be no preconceived ideas. "

After leaving the school, Xu Zheng was still thinking about Professor Ji's criticism and education just now. He found that after solving so many cases, his mentality was not as enthusiastic as when he first came into contact with criminal investigation.

Is this the "three-year pain, seven-year itch"?
However, Professor Ji is right to remind you that any case must be investigated with suspicion.

At three o'clock in the afternoon, Xu Zheng, Zhuang Yongshan and Gu Jia rushed to the Yuhuatai Criminal Police Brigade. As the captain of the Criminal Police Brigade, Lu Shen saw him coming and stretched out his hand from afar, "We are looking forward to the stars and the moon, but we are looking forward to you." A new criminal investigation expert is back."

The two had cooperated before and had a good relationship. Xu Zheng shook hands with him and complained: "I am not a criminal investigation expert. Compared with you old criminal investigators who have been working for more than ten years, I am just starting out. "

Lu Shen laughed loudly, "Yes, yes, you created the Longzhong pair when you were just a fledgling, and established the Three Kingdoms. Then look, should I come to visit the thatched cottage three times?"

"Haha, Captain Lu is joking. I'm on a business trip out of town. If you call me next time, I'll drive over immediately and won't let you wait another minute."

The two joked with each other for a while and then walked into the conference room. Lu Shen asked his subordinates to briefly explain the case and the process of tracking the suspect in the past three days to Xu Zheng.

At 2035:12 pm on December 17, 110, the [-] command center received a call from a woman saying that her husband had committed murder. When the patrol police from the nearest police station arrived at the scene, they saw the door open and the woman’s head buried in her chest. In front of me, I sat on the bedroom floor with yellow water flowing below.

On the other side of the bed, there was a naked man lying on his side on the ground.
The patrol policeman put on shoe covers and gloves, first tested the man's breathing and found that he was already dead. Then he took the woman out of the room and notified the superior unit, Yuhuatai Criminal Police Brigade.

After receiving the police report, Lu Shen immediately rushed to the scene with his backbone. According to the woman's confession, while she was exercising with her lover, her husband suddenly walked in from the door with a grip stick in his hand.

When someone caught this kind of affair going on, she and her lover panicked. Seeing her husband being so aggressive, the woman directly chose to kneel down and beg for mercy, while letting her lover go first.

But her husband didn't care about his kindness at all, and slapped her unconscious. When she woke up again, she found that her lover was already lying in a pool of blood, not breathing, and his body had no heartbeat.

She was so frightened that she called the police.

After a brief investigation, Lu Shen and the others quickly listed the woman's husband, Mai Jingwei, as a suspect. However, the incident occurred at about 10:[-] pm, and the woman was unconscious for [-] minutes. By the time they arrested Mai Jingwei, More than an hour has passed.

For three consecutive days, the city inspected hotels, Internet cafes, bars, clubs and other places, but no trace of Mai Jingwei was found.

At the same time, Mai Jingwei's parents, brothers, sisters, relatives and friends were also investigated, but no one found his hiding place.

The Sky Eye system and various public transportation methods also had no results.

It was as if he evaporated from the world and disappeared without a trace.

"Xiao Xu, in the past three days, I have slept less than ten hours." Lu Shen complained directly to Xu Zheng in front of everyone, "This is not approaching the New Year, and the superiors require stability. After all, this matter has been posted online. It was quite a big fuss.

The leader has given us a deadline to catch the suspect.

Otherwise, brother, this position will not be guaranteed. You have to help us this time and see if there is any way? "

Xu Zheng smiled bitterly and shook his head, "Team Lu, let's talk about it. The suspect has been running away for three days now and has missed the golden period. I can only say that I will try my best."

"Just try your best. I'm surprised. Tell me, where can this person hide?" Lu Shen scratched his head. For a captain, a ounce of oil could be shaved off his hair.

Xu Zheng did not laugh at him, but gave him a sympathetic look and got down to business, "Before I came here just now, I went to my teacher Professor Ji Qianli. He and the forensic doctor Lu from the city bureau discovered a suspicious point. Lu Did the forensic doctor tell you?"

"The forensic doctor in our branch came to the conclusion that the grip stick was a tool for committing the crime, and the wound was caused by a broken skull, which damaged the brain." Lu Shen asked his men to get the forensic identification certificate, "According to regulations, the forensic doctor in our branch issued a test After the report, it will be submitted to the higher-level unit, that is, the municipal bureau forensic doctor Lu, for re-examination.

I haven't received the test report from Forensic Doctor Lu yet.

What, did he discover anything? "

Xu Zheng nodded and briefly explained to everyone the judgments of Professor Ji and Forensic Doctor Lu. Finally, he also expressed his own opinion, "I believe in the opinions of these two professionals, Professor Ji and Forensic Doctor Lu.

Then there may be two suspects.

Mai Jingwei may be the murderer, or he may not be, or his blow may not be fatal, but another murderer may be responsible for the follow-up blow.

Now you can't find any trace of Mai Jingwei, and neither can I. After all, no matter how high my IQ and ability are, I can't compare to the big guys, right? "

At this time, a colleague from the Yuhuatai Criminal Police Brigade said: "Director Xu, just tell me how to investigate. We will all listen to you."

"Yes, Director Xu, you are an expert in criminal investigation and tracking. Our captain is convinced and we are willing to listen to your command."

"."

The people below begged Xu Zheng eagerly, even Lu Shen, the captain, looked forward to it, and Xu Zheng was also speechless. It seems that they must have been persecuted by their superiors to die.

There is no way, one level at a time, one level at a time, and the investigators are worried all day long. After all, it is the end of the year. If the suspect is not caught, there may be no bonus this year. Who doesn't want to have a good year.

If there were no bonuses, would the Chinese New Year be fun?
