Ou Fang also didn't sleep all night, he has been a criminal policeman for 15 years, and he has long been accustomed to this kind of work rhythm and busyness.

At one o'clock in the morning, a group fight broke out in a bar on Huashan Road in Xujiahui, and the SWAT team and the three criminal police teams were out of the scene.

As soon as the European side returned to the office, he couldn't sleep, thinking that three days had passed since the 718 case, and the progress on his side was not ideal.

According to the usual practice, cases that cannot be solved in three days will drag on for a long time, and then they will be squeezed back by new cases, and the time will drag on for more and more, and finally become an unsolved squeeze case.

There is an unwritten unspoken rule in the criminal police team: murder cases must be solved. If the murder case for which the major case team is responsible is not solved for several months, the results of the year-end assessment and evaluation of the squadron leader and the leader of the major case team will be affected.

It's not just a pressure, it's a motivation. No one wants to be left behind, and they all want to be the first.

The European side has been the captain for five years, and it has been smooth sailing, and the solving rate is not the highest in the criminal investigation center, but it is not the lowest. However, this year is not ideal, there are major cases left almost every month, the detection rate is getting lower and lower, and it has become the lowest squadron in the entire criminal investigation center. The fifth major case group of the Second Squadron is the group with the lowest crime solving rate in the team, and it is also a group that is seriously lagging behind.

For this reason, in recent months, the European side has devoted almost all of its general energy to the fifth major task force.

The 718 case, because it involves foreign-funded enterprises, is related to whether the introduction of foreign capital in Donghai City is smooth. In order to eliminate the impact, the city leaders ordered the city bureau to solve the case within one month. To this end, the European side also signed a letter of guarantee to the leaders of the Criminal Investigation Center and the Municipal Bureau. If the case cannot be solved within a month, he will take the blame and resign.

Wu Fan made a report. Entered the office of the European side.

There are not only the European side in the office, but also Sun Guowei, the leader of the fifth major case team, and the backbone Shao Xiaoqiang and Qiao Xiangyang. When Wu Fan entered the door, the four of them were discussing and studying the facts of the case and analyzing some new information obtained last night. Seeing Wu Fan come in, the four of them all closed their mouths and looked at him.

"Wu Fan, sit!" Ou Fang pointed to the chair in front of the desk and motioned for Wu Fan to pull over to the sofa area.

Wait for Wu Fan to set up a chair and sit down. Placing the backpack on the floor next to the chair, Ou Fang then asked, "Xiao Wu, how did you think about it last night?"

Wu Fan smiled slightly, took out a notebook from his backpack in a matter-of-fact manner, turned the first page, looked at the outline listed at the morning meal, and said, "Hello leaders, my opinions are immature, and I hope to get your correction." ”

"Don't be afraid. To be bold and say that even if you say something wrong, it doesn't matter. Sun Guowei took a sip of strong tea and lit a cigarette that had been double happiness.

"Thank you! I hurriedly read all the materials on the 718 case yesterday afternoon, and then based on what I saw at the scene. The analysis is as follows:

First of all, based on the scene of the crime, I make the following assumptions about the crime process.

The first hypothesis is that there is only one perpetrator.

Judging from dormitory door locks, latches, several remnants from the roof of the building, and extracts from the reinforcement of window guardrails. The murderer took advantage of the rainy night to climb into the dormitory through the window of the outer wall to commit the crime. Locking up of suspects. I asked some martial arts people yesterday, and they said that there was once a mysterious secret technique of bone shrinking in the East China Sea. That person was Gou Sheng, who was once known as the first thief in Jiangnan. Although this kung fu has not reappeared in the rivers and lakes for seventy or eighty years, it cannot be ruled out that Gou Sheng's descendants have been passed on to this kind of exercise and learned this skill. In this way, the murderer will shrink his bones, which is the first condition.

The murderer's method of killing the deceased is clean and neat, and it is obvious that he has become accustomed to death and has a strong psychological quality. Thus targeting the murderer is one of mercenaries, killers, military personnel, or repeat offenders. At the same time, according to the traces of the fight, the second deceased was a tall and fat man, and the murderer had certain fighting skills.

Thirdly, judging from the straight edge of the second deceased's erect neck who was killed after the struggle, and there was no deviation at all, the height of the murderer's shoulders was similar to that of the second deceased, about 1.8 meters. The body of the authentic bone shrinking skill will be reduced by 30~50%, but the reduction ratio of the head is not more than 20%, according to the widest part of the gap between the two steel bars of the protective window is only 12 cm, we can deduce that the murderer's body is thin, especially the chest is not tall enough, the chest muscles are not developed, and the head is slightly smaller than normal.

Fourth, the gap between the incisions on the necks of the two deceased was small and deep, and all of them cut the trachea with one knife. But I noticed from the photo that the direction of the knife edge is from left to right, the upper edge is neat, and the lower edge is slightly uneven, indicating that the murderer is left-handed, holding a knife in his left hand, and this knife is usually sharpened on one side when sharpening the knife, the upper edge of the blade is straight, and the lower edge is a slope. Swinging a knife and slashing his throat, he controls it precisely and quickly, apparently specially trained. I remember when I was at the Jiangwan Bureau, Team Zhou showed me a clip of training at West Point and the U.S. Navy SEALs, and one of the tricks was a frontal, side, and back throat cut. If it is used in the 718 case, it is very consistent.

......”

I thought that Wu Fan, an inexperienced newcomer, would not be able to say any new opinions on building a new at all, so he finished it in one or two sentences. But everyone didn't expect that Wu Fan would be open-mouthed, and based on the traces left at the scene and the photos of the crime scene, he would clearly speculate about the process of the crime and the murderer's figure and professional skills. The four of them were dumbfounded, listening attentively, and they didn't even dare to breathe, for fear of disturbing Wu Fan's train of thought.

“...... Of course, there is also a way to commit a crime: two people cooperate to commit crimes. The first murderer climbed in through the window with bone shrinking, and then opened the door to the hallway, and put the real murderer into the dormitory.

The second assumption I don't think is advisable, the loophole is too big.

Then there is the motive for the killing.

I believe that the murderer's motive for killing was not theft of technical intelligence, but vendetta. The purpose of his taking of the deceased's money and calculations is to confuse us from solving the case.

This can be easily judged by the order of the two deceased at the scene.

Generally speaking, the purpose of stealing technical intelligence is to quietly gain the advantage of the other party and make up for the weakness of peer competition. They would never kill people with great fanfare. Because in that case, even if the technical information is stolen. I don't dare to use it, but it will attract our attention. This is called more than you lose.

We can assume that if the murderer enters the house and starts stealing the computer, and is discovered in the process of stealing, then the first person he wants to kill is not the person sleeping in the bed, but the person who finds him as quickly as possible. Then the fight between them was in the morning, and things flew on the table, and one of the kettles and other items smashed into the dead man on the bed, which is shown in the photo. Such a big battle will definitely wake up the second person. The second person will struggle even if he will not fight back. Then there would not be a second person who was not killed.

Based on this assumption, I believe that the first act of the murderer after entering the room was to kill someone, and directly killed the first deceased in his sleep. But because it was so dark in the room, he must have touched something in the room, which woke up the second deceased. The second deceased reacted quickly, getting out of bed and fighting back before the killer could pounce on him. And so there was a fight. caused a messy scene at the scene.

So, I think it's a vendetta, not a stealing killing. ”

Wu Fan said this, looked at Ou Fang and the others stupidly, and stopped. It seems to be watching everyone's reaction. And because he talked too much together, his lips were a little dry, so Qiao Xiangyang immediately brought him a cup of tea. patted Wu Fan on the shoulder, "Good boy." That's a great point! Drink some water first, and go on. ”

"Thank you!" Wu Fan turned out to be a teacup. Took a big sip.

The tea water is a little bitter, and the taste is so far worse than the Wuyi Mountain Da Hong Pao he drank from Xu Fuchun last night, it is simply difficult to swallow. I couldn't help but sigh in my heart, "It seems that people have enjoyed good things, and it is difficult for Jin to adapt to bad things." ”

The other people's brains were spinning rapidly, quickly scrutinizing Wu Fan's analysis.

After a long while, everyone looked up at Wu Fan.

"Xiao Wu, if you judge according to you, how will we arrest the murderer next?" Shao Xiaoqiang couldn't hold his breath and asked.

"I've looked at hundreds of interrogation records, and the two deceased have one thing in common - lust. There are more female workers in the electronics factory, and the two of them have taken advantage of their positions to have many records of female workers. As long as we find the women who have been raped by them, and then find out if they have boyfriends or siblings, and among these men are soldiers, repeat offenders, or martial arts masters, then we can narrow down the scope of the investigation. Secondly, we can find out those who usually have a deep hatred with two or one of them, and then rule out the possibility of committing crimes one by one. ”

Wu Fan finally finished analyzing his case and investigating the plan, he didn't care if it was right or not, whether it was true or not, and no matter what difficulties there were in such a bad situation, he just said it anyway. If you don't believe it, then treat it as nonsense.

"Good!" the European side was the first to applaud. As soon as he applauded, Sun Guowei, Shao Xiaoqiang and Qiao Xiangyang all applauded together.

Wu Fan was a little embarrassed, but he saw the approving eyes of his predecessors, which greatly increased his self-confidence.

Although all the analyses are still untested assumptions, the fact that a new criminal police officer can think and analyze problems in this way gives the European side hope and the growth of a good criminal policeman.

"I think Comrade Wu Fan's analysis and judgment is very reasonable, Lao Sun, our next work will be done in accordance with Wu Fan's suggestion, the preliminary judgment is a vendetta, and immediately send someone to investigate the working girls of the deceased's workshop and the design and development department, especially those women who are beautiful and have good figures. In addition, I asked three groups to investigate the people who had a grudge against the deceased. The scope of investigation can be appropriately expanded. In addition, all the people in the squadron are sent to you, especially the female policemen. ”

"Team Ou, the investigation is a meticulous and long job, if the direction is wrong, won't we have to delay for a long time?" Shao Xiaoqiang thought that Wu Fan's spirit was to be encouraged, but he didn't expect that the European team really used Wu Fan's method to investigate, and also transferred people from the three groups over, so it seemed a bit too much.
