Su Cheng explained: "In the first two cases, they targeted 40 million, not 10 million, and this time they targeted 10 million, not 40 million. After the previous two kidnapping cases, the police believed that the 10 million yuan was a means to throw stones to ask for directions and test whether the police would intervene, otherwise why didn't they transfer 50 million yuan directly? This time they wanted to take advantage of the police's misunderstanding and take away 10 million yuan. People are not as good as heaven, and we have solved an old case. Once we decide that it is a copycat crime, we can understand what they think by empathy. ”

Plainclothes came over and said, "Team Xu, should we arrange for the protection of the victim's family to transport the ransom?"

Su Cheng pondered for a while: "I'm not sure if there is a problem with Jiang Yu's tracking, except for Jiang Yu, the police have not been exposed yet." What is more troublesome is that if Zhang Bing and Zhang Yi conspired to commit the crime, we cannot seize all the stolen goods, once the 10 million cash is hidden by them, we lack evidence against them. "These two men have some experience in counter-interrogation.

Xu Xuan asked, "How was the ransom photo?"

Plainclothes smiled bitterly: "Boss, 10 million, 100,000 shots, even if you shoot one second, you have to shoot 100,000 seconds, and you have to shoot for 28 hours." ”

Su Cheng pondered: "Ten million weighs about one hundred and twenty kilograms...... Normally, tools are needed, at least carts. Zhang Yi and Zhang Bing should have one of them drive to transport the money. At present, I speculate that the person who transported the money was Zhang Bing, and Zhang Yi had a special need to meet the needs, so there was still one person missing, that is, the kidnappers who guarded the hostages. According to the research of criminologists, if Zhang Yi and Zhang Bing, two such good people, conspired to commit the crime, it would be difficult to find an accomplice again. There should only be two people who committed the crime, so how did they commit the crime?"

Seeing that the time was almost 11 o'clock, Xu Xuan contacted: "Sinan, Zhang Bing's location." ”

Sinan replied: "Zhang Bing is at home. ”

"At home?" It's strange again, if two people commit a crime, how to assign jobs?

"The kidnappers called. ”

Su Cheng and the others each picked up the phone, and the kidnapper said electronically: "Is the money ready?"

"Ready. ”

"According to the agreement, six sturdy supermarket shopping bags divide the money into six parts, and each bag of money is wrapped in a shopping bag. ”

"Yes. ”

"Send me an email and send you a video. ”

Sinan called at this time: "Zhang Bing went out." ”

Xu Xuan asked, "Did you take the phone?"

"Nope. ”

That's Zhang Yi's call, the kidnapper here hung up the phone and sent a video to the mailbox, An An was blindfolded and sat in front of a TV, the TV was playing an advertisement, and there was a noon news countdown in the lower right corner, that is, the video started at 10:59, and soon the advertisement ended, and two hosts appeared, stating today's date, lunar date, today is the International XX Festival, the host introduced the main content of today's news, and the video ended.

This is not a hand-held video, but a fixed-point video, which is filmed with a camera positioned in one location, which means that there is likely to be no one in the place where An An is being held. The technical department fed back the news, the mobile phone was located, in the southern district, nine times out of ten it is a puppet mobile phone, it is recommended not to act rashly.

The kidnapper called again: "Take your mobile phone and six shopping bags filled with money and go out, two shopping bags are bottomed, one is tied with a dead knot, one person, drive a white shrimp shell car, I'm staring at you." Within 20 minutes, you will arrive at South 9th Road. As a reminder, move fast, or you'll have to go overspeeding. ”

South 9th Road, six kilometers away from the outer road.

Xu Xuan contacted: "Bobcat, is it in place?"

The lynx replied, "Me and the wildcat are already in place." "They illegally parked on the outside road non-motorized lane. Cameras and recorders are installed in the front and rear of the two vehicles, which can shoot most of the scenes along the outside road. However, after all, it is a hot spot for illegal parking, and many vehicles take advantage of this loophole to park illegally, and their vision may be obstructed.

With the help of the security guards, An's father transported the money to the white shrimp shell car, and drove away quickly, and the time given by the kidnappers was really rushed. Su Cheng snapped his fingers and greeted: "Trouble you for lunch." ”

The two plainclothes and housekeepers looked at Su Cheng together, Xu Xuan turned his face sideways, I don't know this person. Su Cheng said calmly: "Don't worry, they have experience in counter-investigation, and they will definitely let An An's father go around in circles." ”

Xu Xuan contacted the technical department here, and they were analyzing the video received, and the technical department said: "There are two good news, the first good news has a special background sound......

It's hands-free, Su Cheng said: "This is bad news, it's much more difficult to get a more special sound in City A than not to have a special sound." ”

"The second good news is that we think this is a container house. "In many tourist attractions, and in some big cities, there are container houses that can be rented, the rent is not expensive, the location is good, and you can rent for a short time and a long time. For example, the lowest price of a hotel in a tourist destination is more than 400, but the container house is only 60 yuan per day. The container house is a temporary building, which is valid for two years after the application is approved. There is still a gap in the law, and this type of house is now becoming popular in the country.

There is such a typical case, a resident of the urban-rural junction put a container on the roof of his house, and the judiciary, urban management and other mysterious departments went crazy together, the container does not belong to the structure, nor does it belong to the building, but just a big box, and you are not allowed to put the box on the balcony of your house? In the face of this problem, only some cities have introduced management measures, but considering that the management measures are incompatible with the law, there has been no clear statement.

City A has regulations on container houses, and half of the container houses allowed to exist belong to A charity, which is used to take in people who are homeless and have nowhere to live in City A. The other 30% belong to the rental nature of tourist attractions, mostly in the suburbs. Another 20 percent are prefabricated houses used by construction workers.

This is good news, the kidnappers are likely not with the hostages, and it takes two hours to find the hostages.

"The bad news is that there is obvious voltage instability on the TV, and we have some internal opinions, some people think that it is a container board house, and some people think that the container has been arranged. The first news that we found the sound of the whistle, combined with which I personally prefer hostages inside the container. "They argue about whether it's a container or a container house, and if it's a container, then you have to find it.

Su Cheng said: "The argument must be inconclusive at the moment, right?"

"Yes, but also analysis. ”

Su Cheng said: "Then you need a person to decide, the person who carries the black cauldron, the organizer of this case is my girlfriend, I don't want her to carry the black cauldron......"

The technical department smiled: "Okay, I'm going back, right?"

Su Cheng was pinched by Xu Xuan, Su Cheng said: "I suggest that the container board house at the abandoned construction site be checked first, but it can't be checked now, once the hostage is found nearby, the other party is likely to find that the police are involved." "Except for this type of prefabricated house, the other prefabricated houses are under unified management, and the kidnappers may not know whether they are police or administrators. However, some construction sites are abandoned, or container prefabricated houses that have not yet been relocated. This also confirms the instability of the TV voltage, which is basically determined to be battery powered. Zhang Bing and Zhang Yi have not yet been exposed to much technical criminal investigation knowledge.

Su Cheng hung up the phone: "This proves that I deduced before that the kidnapper's target was 10 million, not 40 million." Now it's up to everyone's luck and strength. ”

......

The next thing is a head-to-head confrontation, at 11:50, An's father drove to the outer road, and the technical department has been connected to Anfu's car dashcam, you can see the car pull over, and you can hear An's father open the trunk and get out of the car. About thirty seconds later, An's father returned to the car and drove away. Because An's father got an instrument on Nanjiu Road before, and suspected that it was a bugging device, An's father was inconvenient to contact the police when he was driving, and he didn't know how he put the ransom.

Bobcats and wild cats were not very lucky, their cameras were blocked by other illegally parked vehicles, and no scenes were captured, and Zhang Bing was currently positioned to have lunch in the southern district, and Zhang Yi had disappeared. Xu Xuan proposed a new possibility, Zhang Bing is innocent, Zhang Yi is the mastermind, in this way, Zhang Yi's accomplice is someone else.

Su Cheng ignored it, he was watching the video, it was the video of the outer road taken by Sinan in the morning, and the video of An's father's dash cam.

Soon Su Cheng clapped his hands: "Paralyzed, I was played." ”

Everyone hurriedly gathered around, and Su Cheng pointed to the screen: "The money was put in this trash can, why do you use a shopping bag to hold money? ”

Su Cheng saw that everyone wondered: "Don't you understand?" Zhang Bing rented a van, there is a bottomless garbage can in the van, and this location is a manhole cover, no residents near this side will throw garbage at this garbage can, only passers-by will throw garbage, garbage bags can withstand the pull of general garbage, but can not withstand more than 100 kilograms of banknotes, the money will slide down. If I'm not mistaken, Zhang Yi is already waiting under the trash can, taking the money and leaving. Although the development zone is not close to the outer road, they are only one kilometer away in a straight line. As long as Zhang Yi brings a portable trolley, he can transport the money through the sewer. ”

Su Cheng said: "What are you waiting for? Call the technical department to check the sewer blueprint." "Can a person use a portable trolley to pull away more than 100 kilograms? Looking at the commodity parameters on the Internet, most of them have a weight limit of 75 kilograms, and there is also a 100-kilogram weight limit, can they run twice? No, although their physique does not meet the standards of front-line police, they are students of the police academy after all, and they can carry two bags and pull four bags for one to two kilometers.

Five minutes later, the technical department called, and the situation was not very optimistic, because of the special nature of the diplomatic area, so every five days there is a professional team to clean up the precipitated garbage. The outer road is the main sewer, which is very large and wide, and the main drainage road is the main sewer, although this sewer is very foul, but you can drive a car into it. The second bad news is that the main sewer is connected to many sewers in the development zone, which reduces the pressure on the sewers in the development zone during waterlogging. The third piece of bad news is that the main sewers have an infinite number of outlets. The sewers in domestic cities cannot be called sewers, and it is more appropriate to call them sewage pipes. A hundred years ago, the sewer designed by the Germans on Qing X Island is 2.5 meters X 3 meters, which cannot be said to be the largest in China, at least larger than most cities. In recent years, urban waterlogging has become more and more frequent, and the biggest reason is that the drainage capacity is too poor.

In fact, there is also bad news, An An has not yet been found, do you dare to contain the suspects? If you want to contain them, the technical department will dispatch patrol police from all over the place according to each exit, and then look for suspicious vehicles and lock the rats in the sewers. However, the police in City A took the safety of hostages as the first criterion in handling the case.

The technical department sent a blueprint, Su Cheng couldn't understand the dense pipeline at all, a plainclothes person understood some, introduced: "The main waterway of City A is generally built more than two meters, usually on the sidewalk and other routes with relatively low pressure, and most of the branch roads use low iron fences to intercept large garbage......"

"I don't need to explain so much, I need to be close to the outside road, within two kilometers of the non-hotel, the hostel where you can shower. "A person who has been walking for kilometers down the sewer needs the most bath, to get rid of the smell. From the perspective of counter-investigation, it is also necessary to clean the clothes and body so as not to leave evidence.

Everyone now takes Su Cheng as the leader and contacts each other, Su Cheng suddenly raised his hand and frowned: "It is impossible for Zhang Bing to find out the police surveillance, Zhang Yi suspects that there is police surveillance, in this case, why did Zhang Bing go to the southern district for lunch? Why didn't Zhang Bing exchange roles with Zhang Yi......"

Su Cheng said: "Check if there is any private club or anything like that nearby, Zhang Yi is a member." ”

, it's too uncomfortable without Song Kai, Su Cheng is used to the support of Su San and Song Kai, originally a sentence came out, and there will be a response soon, but now I have to contact the technical staff.

Fortunately, the technical department is quite conscientious, and they have complete information, most of which comes from the network of the police station, such as the opening record of the hotel. However, it is difficult to say whether members of private clubs are registered to connect to the Internet. Luckily, there aren't many private clubs nearby. The technical department got a clue from another aspect, and the technical department reported: "In Zhang Yi's information, he is a member of the Royal Fight Club, and he has been a member of this fight club since his freshman year. The Royal Fight Club is 1,700 meters away in a straight line. ”

Su Cheng looked at the information, Zhang Yi is a native of Linyuan County, and was admitted to the Police University, which is only five bus stops away from the Royal Fight Club, and many students from the Police University are members of this fight club. This brother in the technical department is also there, so the first thought is to find Zhang Yi's information.

"Do you dare to bet, dare to bet that there are no gangsters around An An?" Su Cheng meant, dare to bet, then we will round up now, and there is still time for everyone to get the stolen goods. Don't dare to gamble, Zhang Yi's body and clothes are clean, and it is estimated that the money is hidden, even if the money is found, it is difficult to accuse Zhang Yi.

"Don't dare to bet. Xu Xuan replied very clearly, what are you kidding.

Sending patrol officers who are not very experienced in criminal investigation to the Royal Fight Club to collect evidence is too risky. It's better to bet.

Su Cheng asked: "Is the location of the car rented by Zhang Yi still in the commercial building?"

"Yes. ”

Su Cheng nodded, this information is not very useful, Zhang Yi must have dismantled the positioning system and placed the positioning system in the parking lot of the commercial building, which is also a technical witness. It is inferred that Zhang Yi will go back to get the positioning system after cleaning, but he will definitely hide the money before. Even if Zhang Yi is caught at the Royal Fight Club now, Su Cheng is not sure that he will find the money, and Su Cheng is not sure that the money has been hidden, or not.
