Chapter 126 Professor Fan's Confusion
Xia Yan's heart was in a mess. If Qi Xin's family of three were really murdered, then the nature of the case is too bad!
All of a sudden, the good mood of discovering the source of the corpse disappeared at this time.

"I'll start investigating immediately!"

Xia Yan suddenly felt that the chair was hot and couldn't sit down at all, so he pulled Zhou Zheng up and left towards the criminal police team again.

Having nothing to say all the way, Xia Yan showed a preoccupied look. After returning to the criminal police team, he began to organize the criminal police in the team to investigate the social relationship between Qi Xin and Su Xi.

Zhou Zheng watched Xia Yan's deployment helplessly. He was sitting on Xia Yan's desk, his eyes focused on the forensic report he had just put down.

Now that the report is over, there is no point in staying here, it's time to go back and rest.

However, just as he was about to leave, he suddenly remembered something and hurried forward to stop Xia Yan.

"Captain Xia, there is one more thing that I almost forgot." Zhou Zheng walked up to Xia Yan and said in a low voice.

"What's the matter?" Xia Yan's brows twitched fiercely, goosebumps arose in an instant, and he faintly felt that there was nothing good in his heart.

"About the Zhang Chi case and the Zhang Xin case." Zhou Zheng said in a low voice.

"You wait for me to get off."

Xia Yan nodded, and then explained a few more words to these criminal policemen, asking them to quickly investigate the information related to those people, especially focus on investigating Qi Xin's family to confirm whether they have lost contact. After all, as long as Qi Xin's family If the person is still alive, then it is not considered a murder case.

Under his dispatch, the criminal policemen of the criminal police team became busy in an instant, and everyone performed their duties in an orderly manner.

After a while, the criminal police office was empty, only Xia Yan and Zhou Zheng were left.

"Zhou Zheng, what did you want to say just now?" Xia Yan wiped the sweat from his forehead with his hands. Xia Ye wasn't that hot, but at this moment he felt a particularly exhausting feeling, and the way he looked at Zhou Zheng became different. He was a little afraid that there would be something bad in Zhang Chi's case and Zhang Xin's case.

"The thing is like this..." Zhou Zheng's voice sounded slowly, and he told Xia Yan his complete analysis, including his simple portraits of the suspects in these two cases, and the two suspects he identified There may be some kind of relationship between people.

"Is it really a serial murder case?" Xia Yan sighed for a long time. In fact, when Zhang Xin was killed, he had such a strong premonition in his heart. After all, this kind of thing was too coincidental. Are there any more portraits of the suspect?"

"No!" Zhou Zheng shook his head and said, "At this stage, the evidence we have is simply not enough to support the combined case of Zhang Chi and Zhang Xin, so now they are still two separate cases, and in these two cases There is so little information available, coupled with two different killers, that they cannot be relied upon on the basis of each other."

What Zhou Zheng said was very clear.

This case is a serial case, but it is not a serial case. After all, the perpetrators are different.

"I understand what you mean." Xia Yan nodded, only feeling overwhelmed, and said: "We will focus on the investigation, and hope to find useful clues as soon as possible."

"Captain Xia, I have nothing else to do. I'm leaving first." After Zhou Zheng finished what he should have said, if he stayed and wasted, it would affect Xia Yan and the others' investigation.

……

It was almost 6 o'clock when Zhou Zheng left the criminal police team of the Municipal Bureau. When he was taking the subway, his phone started buzzing and vibrating.

Suddenly, his heart beat violently.

He already had a certain stress response, as long as the phone rang, he was worried about whether there was a murder.

Picking up the phone and looking at the screen, he suddenly saw Professor Fan written on the caller ID.

"Damn!"

Zhou Zheng slapped himself on the head hard. The recent successive cases made him forget the agreement with Professor Fan.

He quickly connected to the phone and said, "Professor Fan, I'm sorry, I just got off work."

"It's okay. I have something to do here. I just finished my work. I'll pick you up at the subway station near the school." Professor Fan's steady voice sounded from the phone.

"Okay!" Zhou Zheng responded quickly, and then hung up the phone.

He leaned back, leaned on the hard seat of the subway, looked straight at the opposite glass, watched the occasional lights and shadows in the darkness flash across quickly, and what happened in Professor Fan's office came to mind.

The first case solved in his life, that is, the case in which Wang Fan was hanged, will be tried in court tomorrow.

All relevant procedures have been completed.

Criminal cases are different from civil cases. It takes less than half a year for many civil disputes to be settled from the filing of the case to the formal trial. This is why it is very difficult for many ordinary people to protect their own interests when encountering some rights protection cases.

Even trial after trial is enough to consume patience, and none of us have so much time to waste.

However, criminal cases are different. The people's procuratorate will make a decision to open a trial within one month for a homicide case transferred by the public security organ.

When a people's court tries a public prosecution case, it shall issue a judgment within one month of accepting the case, and no later than one month.

Wang Fan's case was less than a month old, and it fully complied with laws and regulations, and the efficiency of such acceptance was already quite high.

The court will officially start tomorrow, which indicates that tomorrow is the day of Wang Fan's death.

Wang Fan committed a total of three murders, and they were crimes against strangers. The impact was extremely bad, and there was no room for maneuver.

Before the court session, everyone knew very well that what awaited Wang Fan was the execution of the death sentence immediately, so after tonight, this person would die.

Here is a cold knowledge. When sentencing a murderer, whether he is familiar with the victim is an important point.

If the murderer killed an acquaintance, and there is a certain causal relationship between the two, then the judge will measure the killing.

However, if a murderer kills a stranger, it represents a great social danger. There is no logical causal relationship in the act of killing, and such a situation is severely punished.

Wang Fan will definitely be executed!

No one doubted this, including Zhou Zheng and Professor Fan.

Therefore, Professor Fan asked him to go to Jianghaidongdong Prison tonight to visit Wang Fan for the last time before his execution.

Zhou Zheng had never been to a prison or visited a criminal before, so he didn't understand the procedures at all. However, Professor Fan had already arranged these things, as long as others followed suit.

For such a thing, he was a little confused, not knowing what the conversation with the murderer would be like.

"Jiang Medical University Station is here..."

Just as Zhou was thinking, the subway arrived. He got off quickly and got out of the station. After exiting the station from Exit C, he saw Professor Fan wearing gray trousers and blue short sleeves.

"Professor Fan!"

Zhou Zheng hurriedly said hello, and walked over at a faster pace. The afterglow of the sunset shone on his body, and he felt a sense of dryness and heat all over his body.

When he saw Professor Fan, he really wanted to ask, aren't you hot?

However, he didn't ask. After all, such thoughts pop up every summer. Professor Fan must be weak and sensitive to the cold. Even in summer, he only wears less clothes during the hottest time.

"I just arrived too." Professor Fan said with a smile, his eyes were focused on Zhou Zheng all the time, his eyes were full of satisfaction and pride, this is his most satisfied apprentice in the past few years, and said: "This way."

"Okay." Zhou Zheng followed Professor Fan's side, and the past scenes echoed in his heart. To some extent, Professor Fan is recognized as the most difficult teacher in Jiang Medical University. Almost no one is willing to take Professor Fan's class. , except for him, the rest of the class are those who are slow-handed during the course selection.

The two walked not far along the side of the road near the subway station, and came to a black Mercedes-Benz car.

This is Professor Fan's car.

Zhou Zheng has seen it before, but not often. Professor Fan is a low-key person, and only rarely parks his car under the teaching building. Most of the time, he parks in the school's faculty parking lot.

"boarding."

Professor Fan took out the key, unlocked the vehicle, then noticed the passing vehicles and walked towards the driver's door.

After being instructed by Bureau Qin, Zhou Zheng understood a little bit about the ways of the world, and walked directly to the co-driver, which also reminded him of an incident in the past.

This is not the first time he took Professor Fan's car. He also took it once before. It was to eat at Professor Fan's house, and he sat directly in the back row.

To this day, he still remembers the feeling of sitting in the back row. The spacious legroom, the seats with monitors, and the sunshades on the windows are simply too comfortable.

"Why don't you sit in the back this time?" After getting into the car, Professor Fan looked at Zhou Zheng, who was sitting in the passenger seat and fastened his seat belt, with a smile on his face again.

"Ahem... I was not sensible before." Zhou Zheng coughed twice in embarrassment. Thinking about it now, he was like the young master of a rich family, and Professor Fan was like his personal driver.

"You don't have to be so polite with me." Professor Fan's tone didn't fluctuate at all. He started the car and drove out. The quietness and stability of the car were very good, far beyond the comparison of the police cars.

Zhou Zheng didn't know how to answer, so he simply kept silent. He glanced at the steering wheel at the driver's seat, and there was a round three-pointed star emblem in the middle of the dragonfly shape. With less money, I have already realized the freedom of wealth, and I can still persist in the education position, which can be regarded as my love for education.

The car drove out of the intersection, and just entered the main road, it was blocked in place.

The current time is 06:30, which is the evening rush hour in Jianghai City, and there are too many cars on the road, which has also aroused many people's road rage.

Professor Fan showed no signs of panic at all, and still maintained his own elegance. The closed car windows almost cut off most of the whistle from the outside world, and the moderate temperature of the air conditioner greatly increased the comfort in the car.

"What song do you like to listen to?" Professor Fan flipped his fingers continuously on the car technology screen.

"Well... I can do it, Professor Fan, you can choose." Zhou Zheng hesitated for a moment while pursing his lips.

"Okay, then this one." Professor Fan chose a piece of pure music with a melodious melody.

The sound of the music is just right, it will not affect their chat, and it will cover up the noise of the outside world.

When the green light is on, the staged congestion is relieved and the next congested section is entered.

Professor Fan controlled the vehicle steadily, without any setbacks at all while driving at low speed. When it was blocked again and stopped, he glanced at Zhou Zheng and said, "Have you encountered any difficulties in investigating the case recently?"

"Have!"

Zhou Zheng's eyes suddenly lit up, and he almost forgot that this was Professor Fan. Director Ma and Qin couldn't wait to invite him to the boss of the City Bureau, who was right by his side, so why did he forget to ask.

"Teacher, I recently encountered a difficult murder case. Well, to be precise, there are two cases."

Zhou Zheng spoke immediately. When he was sitting in the car, he was still thinking about the case.

"The first homicide happened first. The victim had no traumatic injuries and no signs of struggle. He died in his own home. The only symbolic thing was that all his teeth were pulled out and he was taken away by the murderer. , the murderer used drugs, stunned the victim and strangled him to death."

"The second homicide occurred the next day. The deceased was the father of the victim in the previous case. He had just arrived in Jianghai City in the morning. After claiming the body, he died in a hotel where he stayed temporarily. There were multiple club wounds all over his body. Suffering brain contusions caused by multiple blows, the deceased was violently knocked out all his teeth by the murderer when he was on the verge of losing his resistance, and took him away."

"According to the investigation of the crime scene and the corpse, I believe that the murderer of the first murder case is a woman, and the murderer of the second murder case is a man. Since the victims of the two murder cases are father and son, the methods of death are different, but both have the characteristics of knocking out teeth. , I think the murderers of the two murders are related in some way."

Zhou Zheng immediately told Professor Fan about the case. After he finished speaking, he fixed his eyes on Professor Fan, full of expectation, hoping to get some answers that could help solve the case.

"I heard the case clearly, Zhou Zheng, what's your problem?" Professor Fan stared ahead. The road conditions at the moment were not good, but it didn't hinder his thinking.

"My question... is what I just said. I think there is a relationship between the two murderers!" Zhou Zheng was stunned for a moment, then continued: "The murderers of these two murders are different, and the killing methods are different. It is difficult to join the case. There is no way to make a portrait with the evidence of the time, which makes me a little confused."

"According to your description, I think there is no problem with your judgment. The murderer of the first murder case is a woman, and the murderer of the second murder case is a man. However, this does not prevent these two murder cases from being serial murder cases. When encountering such cases, you can't regard the murderer as a single individual, but as a whole, such as... a gang." Professor Fan's tone was flat, as if nothing would arouse his emotions.

"Group?!" Zhou Zheng's eyes widened suddenly, and a flash of inspiration flashed in his eyes, and his thoughts instantly opened up.

"That's right, the gang. These two murderers belong to the same gang. There may be only the two of them in this gang, or there may be other people. The symbol of their crimes is the tooth. There must be some kind of relationship between the two of them. As long as If you find evidence to prove that they are related, then the two murders can be determined to be committed by a gang, and if the murderer is classified as a gang, there is enough evidence to apply for a merged case." Professor Fan said lightly.

"So that's it!" Zhou Zheng's face suddenly became much lighter. What does it mean to wake up a dreamer with a word? This is it!

However, there are still question marks in his mind.

"Teacher, I still have doubts. Even if it is confirmed that they committed crimes as a gang, how can I give portraits of the people in this gang?" Zhou Zheng asked doubtfully.

"The gang is made up of people. As long as it is a human crime, there will be a fixed pattern. You need to carefully separate the characteristics of the part belonging to different people in the two cases, make portraits of each person, and then combine Let’s take a portrait of the gang together.” Professor Fan’s attention seemed to be still on the traffic jam, and he spoke at a leisurely pace: “It’s worth noting here that every gang must have a leader, that is, the backbone. When doing portraits of the gang, Pay attention to the behavior pattern of the reference backbone."
