The police began to filter areas by school, then excluded some based on geography, and finally left three elementary schools. The police compared the audio and locked down one of the schools. Based on ambient volume, etc., it was determined that between 9:30 a.m. and 9:55 a.m., the person who called Jimmy was located in the area of the East Suburb Second Street Square.

Then, the nearby surveillance on the day of the call was retrieved, and the screening began again, until this step was still a huge project, and after several days of hard work, a suspect was finally locked. But it's a pity that the suspect has been deliberately disguised and consciously dodged the camera, and after being busy for so many days, the only gain is that the murderer suspect, the suspected scarecrow, is between 1.7 and 1.76 meters tall.

The reality is that when the opportunity is in front of you, when you put in the effort, the result may not be as you want.

After Arber sobered up, he contacted the people in his company, and when the police efforts were fruitless, Uncle Abel flew back to Europe by private jet, and Jimmy and four other bodyguards left City A on the same plane. Su Cheng was still a little embarrassed about the fate of the boss, but Su Cheng knew that what the scarecrow boss didn't know was that if he killed an uncle, thousands of uncles would stand up.

……

There are still more than 20 days before the Chinese New Year, and the police force has begun to tilt towards the Spring Festival, not only the cases related to the railway station have entered a period of high incidence, but also the cases of abduction, theft, robbery, and other crimes for money have also entered a high incidence period before the New Year.

Z7 has cracked two burglary and wounding cases in the past three days, Z7 will take over this case, and crimes such as theft and theft must be responsible for a special person, and the progress will be reported within 48 hours, and then the superior will decide to suspend or organize manpower to solve the case.

Su Cheng is not interested in this kind of case, there is no technical content, it is to break in, rob, and leave. Gamble that the police won't mobilize a lot of resources to make arrests.

Everyone else went out to handle the case, Su Cheng stayed in the office and was talking to Xu's mother on the phone, Xu's mother meant that Su Cheng was at Xu's mother's house for the New Year this year, and Su Cheng said that there was no problem. Xu's mother said that the purchase of some New Year's goods would be handed over to Su Cheng. Su Cheng said that there was no problem, and contacted Xu Xuan to discuss the date of shopping to buy New Year's goods.

Su Cheng drank black tea, looked at the cold rain outside, and enjoyed the warmth of the office. The landline rings...... This thing doesn't seem to have been ringing in hundreds of years. Su Cheng answered the phone: "Z7." ”

"Seven groups of major cases?"

"Yes. ”

"Hello, I'm Zhang Liang of the Second Criminal Police Brigade, that's it. ”

There is a bayberry forest from the east bridge of a city to the suburbs, which belongs to the farmhouse, and when it comes to the bayberry season, people can pick it, and a certain fee is charged per catty. This place is a great place to drive and play games for both men and women during the non-bayberry season.

Yesterday, no, at two o'clock in the morning today, the patrol police car passed by Yangmeilin and stopped at the intersection, the patrol officer got out of the car and smoked a cigarette, and heard the sound of an engine at Yangmeilin's location. I got in the car and drove into Yangmeilin Road and saw a car. The bayberry forest is relatively dense and almost windless, and if the car starts in place for a long time, it will cause the occupants to suffocate. Usually the police ignore the men and women playing games, but it is in charge of running the engine.

As soon as the headlights shone on, it was found that something was wrong, a pipe was connected to the exhaust gas, and the rear seat glass was stuck, and the other glasses were closed. In the car, the driver's seat and the passenger seat were a man and a woman, undressed, and in a coma.

The patrol called the command center, smashed the car window, and pulled the two out for first aid.

At around three o'clock in the morning, news came from the hospital that the woman died after failing to resuscitate. The man was rescued and woke up at four o'clock in the morning. In the morning, some language communication skills were restored, according to the man, he and the woman went to the suburbs to talk about work, and soon someone knocked on the car window, and the other party showed his ID, claiming to be a police officer of Department Z, and asked to roll down the glass on both sides. Rolling down the glass, the man took the driver's license, as if handing it out, as if there was none, and then he didn't know anything.

The results of the urine test, autopsy, and blood test showed that there were some anesthetic ingredients in the two people's bodies, which is referred to as T2, which is a special anesthetic used by the police to capture large animals. The SWAT team has not had the opportunity to use the T2 for ten years.

Then why did seven groups be found in this case? The victim man was Xiao Yun, a lawyer, who had talked to Su Cheng when he was participating in a reality show in Linyuan County, and knew each other. This is not the reason, the main reason is that the criminal police team thinks that Xiao Yun is a celebrity, the modus operandi is strange, and T2 is used, so he applied to transfer the case to Department Z.

The case can be taken over by the Z department or by the criminal police team. But because of the sharp increase in criminal cases such as theft a few years ago, most cases require a special person to be responsible, solve them immediately, and try not to hang up unsolved cases as much as possible, so the criminal police team is now busy enough, facing a murder case that seems to be more complicated, plus Xiao Yun has influence and uses T2, so the person in charge of the criminal police asked Zhang Liang to contact Department Z. After Zhou Duan heard about the case, he told Zhang Liang that he could contact the next seven groups, and there were idlers in the seven groups, so Zhang Liang dialed the phone number of the seven groups according to the registration number.

Su Cheng picked the case, and Su Cheng was a little interested in this case as soon as he heard it.

From Zhang Liang's description, it can be seen that Xiao Yun and the woman were quickly put down, and the other party had 10,000 ways to kill the two, why did they choose exhaust?

So Su Cheng took over the case for Zuo Luo, and Zhang Liang drove the file and various materials to Su Cheng.

When Zuo Luo and Bai Xue returned, Su Cheng was looking at the photos of the scene taken by the physical evidence team on the big screen. Zuo Luo ignored Su Cheng, opened the Xiaoice box, poured a bottle of mineral water into his stomach, and then took a breath: "You can really run, chased me for five streets." ”

"What are you chasing?" asked Su Cheng casually.

Bai Xue said: "A burglar. ”

Su Cheng said: "So I prefer to do mental work...... Zoro, there are cases. ”

"There's a case? Why don't I know? I still have to arrest their accomplices, now I'll wait for Fang Ling's news and come back to catch my breath." Zoro sat on the table: "You won't take the case privately, right? Hey, the gang I have at hand is very important, and I have committed seven crimes in three days......

"It's important to me whether it's important or not, it's important to me whether it's interesting or not. Su Cheng said: "This case is super interesting. ”

Zoro said, "Give you five minutes to explain what's interesting." ”

Su Cheng said: "The murderer attacked a man and a woman with T2, and used a very troublesome way to forge the documents of the Z department, connecting the exhaust gas from the exhaust pipe to the car. How can this method of killing take a minute or twenty, and I think half an hour is more appropriate?"

Zoro said: "It depends on the displacement, but also on the physical condition of the victim. Normally, it takes about ten minutes to go into shock, and it depends on what gasoline is burned and the gear is hung. For example, in the neutral gear, there is less exhaust gas, and if it is an advanced gear, stop the car with the handbrake, and the exhaust displacement is relatively large. It is also related to gasoline, and there are many variables. ”

Su Cheng said: "Why do you use this way? And the car is not fully sealed, the back seat has a crack, 2 has a special effect, Xincheng metabolism is very fast, the male victim is alive, his urine test did not find T2, the female victim died, the autopsy found T2...... Why is it so complicated?"

Zuo Luo quietly looked at the file, took the mouse to look at the big screen, then got down, turned on his computer monitor, and began to search.

Zoro said: "When I first came to work in Department Z, I encountered a case where a man and a woman died in the car, and it was tested for carbon monoxide poisoning. According to the investigation at the time, the car was parked in the underground parking lot, not ventilated, and then turned on the air conditioner for a long time, resulting in poisoning and death. At that time, we had a question, the car was at 9 o'clock in the evening to the underground parking lot, the second floor of the underground parking lot was basically empty, and they were going to play games. The time of death at the forensic examination was 11:40. ”

"It's like...... Normal, right?"

Zoro said: "The key is the man, the man has a wife, he went back to City A on a business trip in the morning, and told his wife to come home at half past eleven o'clock this evening, and the man will go on a date with his lover when he returns to City A in the morning." Arriving home at half past eleven has not changed. And it was found that the deceased had purchased a movie that was shown at 9:30 p.m. in the main building. The deceased wanted to play games with his lover in the underground parking lot, and then went to the movies, and went home after watching the movies, just in time. They went to the second basement floor purely to play games, not to chat and talk, and it was impossible for them to stay that long. We have doubts, but because the case was preliminarily classified as an accident and the superstition of the owner of the building, the scene was completely destroyed. ”

Su Cheng said: "No, it's an accident, how can it be given to Z7?"

Zuo Luo said: "Because the deceased was a very famous lawyer at that time, although because of the legal system, the role of lawyers in the court is relatively small, but there is still a big difference between a good lawyer and an ordinary lawyer, and he was the best at that time." ”

Su Cheng said: "Oh, that's a coincidence, this time the male victim is Xiao Yun." ”

"Xiao Yun, the most popular Xiao Yun in the legal profession at the moment?"

"Yes. ”

Zuo Luo looked up at the big screen: "This case is really interesting, let's talk about the preliminary opinion." ”

Su Cheng said: "I think someone wants to disguise Xiao Yun's death as an accidental death. It's just that I met a patrol officer who is a big smoker......"

"On patrols in the suburbs, especially at night, many people smoke. ”

"I'm not criticizing, I think the killer is waiting nearby. Su Cheng said: "What's more interesting is that the murderer used the police ID, or the Z department ID card to let the victim lower the window, and then used T2 to anesthetize the victim." There is another contradiction in it, assuming that the murderer is familiar with T2 and should know that he can't die so quickly, otherwise T2 will be found. ”

Zuo Luo said: "Su Cheng, don't think too highly of us, this kind of case is an unnatural death, the police will conduct an autopsy, but will not do a toxicology test, as long as the autopsy is to confirm whether it is carbon monoxide poisoning, not to confirm whether it was drugged...... How does it feel like this case was done by the police or related professionals?"

Su Cheng said: "Yes, I think so too, first: T2, there are not many people outside who know T2." Second: ID card, the ID card of department Z has never appeared on the Internet, and it is only an identification mark, not a certificate, but there are some anti-counterfeiting details in it, Xiao Yun is an insider, if the document is too fake, he will definitely see through it at a glance. The murderer was familiar with ID documents. And as you said, the killer is familiar with some of the things inside the police, including autopsies. ”

"Well, it took you ten minutes, but you convinced me. Zuo Luo took the phone: "Fang Ling, you and Bai Xue are in charge of the burglary gang case, and if you need manpower, you will draw it from the police station, and I have a case to follow up...... Sole control...... Okay, goodbye. ”

Bai Xue hurriedly left and went to join Fang Ling.

Zoro hung up the phone, pondered for a while, and said: "There is another point you didn't say, sometimes the police and the lawyer are opposed, especially the lawyer. What is a famous lawyer? China's legal system is different from that of HK, the role of lawyers is relatively small, and in order to stand out among many peers, in addition to requiring rich legal knowledge, it also requires some sideways. ”

Su Cheng said: "That...... Xu Xuan investigated a case a few days ago, one of the two young men kicked a woman down the stairs, causing the woman to become a vegetative person. Xiao Yun is the lawyer representing one of the suspects, and the other suspect is a classmate. Before he took over, both suspects denied that they had done it, and after he took over, the two suspects identified each other as the other. But there is only one kick, and the police lack evidence to prove who made this kick, and there is no doubt about the crime. Criminally, the two are not guilty, and each bears 50% of the civil responsibility. "Just like throwing objects from high altitudes, there is no need to prove which household threw the things, all of them can become defendants in one column, and civil favors the weak, and criminal justice is the principle.

"That's the means...... People who watched the excitement thought that the two suspects were dog-eat-dog, but in fact the two had formed an alliance. Zoro took a few bottles of water from the refrigerator and said, "Let's go, let's go to the scene." "This scene is not more than 24 hours old, and it is definitely still under lockdown. The detectives did not speculate that the murderer was lurking nearby, and they would not search for it.

……

The on-site investigation is not optimistic, this bayberry forest is planned to be planted, there are roads, the distance between bayberry trees is not large, and this is a holy place for men and women to play games in the car, there are too many clues, and the traces left by the careful murderer are difficult to identify.

According to the dual-bayonet surveillance video, plus the method of time inference, at about two o'clock in the morning yesterday, there may be seven vehicles in Yangmeilin. Zoro began to visit these car owners, but did not expect to be closed.

Generally speaking, young people from ordinary families usually have difficulty in buying a car before marriage. After a few or many years of marriage, the feeling with my wife is mostly flat, lack of excitement (emotion), have many children, and will not go to Yangmeilin around two o'clock in the morning. Go to Yangmeilin to play car games, or unmarried men and women with a well-off family, or more successful men and women who are married. The latter doesn't want their spouse to know about playing games.

Zoro could only patiently call to do the work, explaining that he would keep the other party confidential. And Su Cheng did not participate in the visit, the visit was too tiring, Su Cheng concentrated on reading the information.
