On a thunderstorm night, the seventh group, including Su Cheng, just finished the case and was enjoying the late-night snack time in the seventh group. As the captain, Zuo Luo hates midnight snack very much. You can't let his subordinates treat you, right? You always have to treat everyone to something after working overtime, but you can't eat too badly, right? So since Zuo Luo became the boss, his wallet has become weaker day by day. Fortunately, when the drug enforcement department was wanted, although he didn't get 500,000 yuan, he still distributed some money. The most important thing is that Zuo Luo's grandfather is quite powerful. The water, electricity, gas and housekeeping deposit cards are all kept at 10,000 yuan, and he even sent shopping cards and oil cards for no more than 10,000 yuan.

Today's midnight snack is sheep's head soup, and rice is the staple food. In the eyes of Fang Ling and Zuoluo muscles, it is unhappy to have no rice on the table.

Song Kai looked at his phone: "It's only the Chinese Valentine's Day in one week."

Fang Ling: "My hometown is a rule to worship ancestors on the Chinese Valentine's Day."

Song Kai: "Where is Qingming?"

Fang Ling: "Grave sweeping, pig."

Song Kai was speechless.

Su Cheng drank soup and mixed some rice. This was contagious. The fresh and spicy rice tasted very good and was very satisfying. However, for himself who lacked exercise, Su Cheng touched his belly: "What major cases have been there recently?" He was more interested in the case. Without the thief police, he enjoyed the fun of detecting the case.

Zuo Luo said: "Generally speaking, the strong case in summer is relatively high, and it's not our turn to take over. Most of the strong case is an impulse and passionate crime, and most of them are acquaintances. As long as the victims are willing to cooperate and have some basic knowledge, it is usually not difficult to arrest people. I am now thinking about Bering and Koeman. Half a month has passed, and there is no news about them."

"If there is news, people will die, either the fish will die or the net will be broken."

Song Kai was eating while playing with his mobile phone: "The consultant, the z department group said that you were in love with Team Xu."

Su Cheng took out his flip phone and said, "It turns out that it was not the news I spread."

Fang Ling jams: "I heard that Team Xu plans to submit an application for transfer to the Interpol."

Before Su Cheng could speak, Zuo Luo was surprised: "Interpol? Not so?" Interpol is the highest-ranking name, but it is the least influential police agency. It mainly serves as a sound tube. It has no judicial investigation power, and is more like a public relations officer between countries. Most of them are civilian positions like Zhan Wuzhao.

Su Cheng said: "I guess Xu Xuan wants to recharge. Although the Interpol is not in the market, she can access the vast international information network and has more exchanges with international peers. Japan, North America, South Korea, Central Europe, Eastern Europe, Africa, etc., in each place, due to the influence of culture, society and law, the criminal police's case handling styles are different. And because of the existence of the two legal systems, they are different in terms of evidence, confession, etc."

Zuo Luo nodded: "For example, the American crime laboratory staff who are famous for film and television dramas are not policemen, but technicians hired by the government. Many technical departments have business dealings with policemen, but they have their own research directions, and there are various sources of funds, some raise funds, and some start businesses. However, no matter which country the police are, visiting is always the biggest job of the criminal police. I think it is a model to discuss."

Su Cheng said: "The group responsibility system and the office leadership system have their own advantages and disadvantages, and it is hard to say who is better or worse."

Zuo Luo said: "I went to the US FBI for half a year to exchange. I think the American family concept is relatively weak. When adults are adults, they are only responsible for themselves. Many criminals rarely consider their family and relatives when committing crimes, and they often have impulsive behavior. They are not strong tolerant, have outstanding personality, and legally possessing guns, and there are many violent cases. On the other hand, American lawyers are priced at real money, and whether they are guilty or not is often the final decision of the lawyers you hire."

Song Kai interrupted the discussion and said, "I'll show you a video. It's only an hour after posting, and the number of clicks reached 70,000."

Song Kai picked up on TV and everyone watched the video together. He originally had a relaxed attitude and thought it was just a spoof of horror selfie videos, but when he saw that the leading actor was a young man and a young couple, everyone became serious.

When the clip was played to the wine glass and was broken, Zuo Luo said solemnly: "This guy is a veteran with a gun." The use of guns is very particular. According to the space and target, each has its own way of holding a gun. For the purpose of threatening, there is no need for any shooting posture. First of all, it is necessary to ensure the safety of the gun and the human body. The minimum safe distance is calculated based on the human reaction. In the film and television drama, a person pointed a gun at another person's head, which was 5 cm away, and this distance would hardly kill the other party. Because as long as the other party shakes his head violently, the reaction nerves and motor nerves of the gun holder cannot keep up. In many cases, the target of the pistol shooting training is not the head, but the body part.

But this death mask was not. Even when facing two ordinary people, he was very careful and sent the bell to the table, but not to the two. There was also the gun-holding hand that was always in a dark position, which was very stable and calm. In the end, the gun was more artistic. When the gun was fired, a little recoil jumped to another target with the wrist turning the muzzle. It can be said that he was very familiar with the performance of this pistol.

Everyone has different concerns. Song Kai is paying attention to the voice. As a technician, he feels that the voice of the Death Mask is very strange, and helium or other electronic means change through mechanical, helium or other electronic means. Fang Ling is paying attention to gossip, couples’ emotions about emergencies, and want to find problems from their faces. Su Cheng cares about the content and tone of the Death Mask’s speech. Zuo Luo is paying attention to the gun.

"Go." Zuo Luo took his coat.

Su Cheng hurriedly said, "It's time to get off work." There are so many police officers in the city, why are you doing? According to Su Cheng's experience, this person is really dead. However, Su Cheng doesn't like to rush to the front line of the scene, because he or she will either get shot or can only provide information and clues to others. It's better to have a good sleep and wait for clues tomorrow before talking about it. It's a physical evidence group, forensic doctor, and technical department to issue various inspection reports.

Zuo Luo said: "I suspect that no police have been to the scene yet."

Song Kai said: "The comments are all discussed in detail below, and it seems that they are spoof videos."

Zuo Luo: "Song Kai, leave support, crack the IP, do whatever you can, notify the physical evidence team, technical department, forensic doctor, patrolman... Su Cheng, Fang Ling, get on the car."

Su Cheng said helplessly: "I shouldn't stay for late supper."

...

Just like Zuo Luo predicted, no police arrived at the scene before. After Song Kai called the patrol police, the patrol police blocked the villa. Fang Ling was arranged to obtain surveillance, visit the doorman, and ask about the work of the patrol security. Su Cheng and Zuo Luo entered the villa.

Put on gloves, shoe covers, put the raincoat and umbrella outside, turn on the lights, and go all the way up. The bedroom door was not closed, and when you walked to the door, you saw the two young white-faced couple lying on the table, which was exactly the same as in the video.

Zuo Luo stepped forward and left the bedroom after confirming that the two died. It was not their time to enter the venue. It was now the working time for the forensic and physical evidence teams. The two went downstairs to wait.

But the forensic doctor came later than everyone thought, and was at least half an hour late. As soon as the forensic doctor arrived, Zuo Luo said dissatisfied: "The body is cold."

The forensic doctor is an old lady in her thirties. He glanced at her: "You have to line up even if you reincarnate."

Su Cheng asked: "Sister, are you very busy today?"

The forensic doctor nodded casually: "Two bodies were pulled in a parking lot in the outskirts of Nancheng."

Su Cheng asked: "When did he die?"

"About three hours, three groups are dealing with it."

"Gun shooting?"

"Yes." The doctor nodded and went upstairs with his assistant. Su Cheng and Zuo Luo followed him to the front of the bedroom.

Take a photo, check, forensic doctor said: "There is no suspense in the cause of death. The estimated death time is about one and a half hours, with an error of twenty minutes. It should be a 7.62 mm bullet.

Zuo Luo said: "I think it should be a Type 67 micro-voice pistol when I watch the video."

The person in charge of the physical evidence group interfaces: "67 Weishen? This is a special pistol." It is generally equipped with reconnaissance and agents. It is not common without equipment from the police force. The smoky and light are small in size and have good shooting accuracy. But relatively speaking, it is at a disadvantage in the shooting of obstacles exceeding ten meters, and is mainly suitable for controlled shooting within ten meters.

The forensic doctor said: "The two bodies I just pulled were also 7.62 mm."

Zuo Luo connected: "Song Kai, are there any related videos?"

Song Kai replied: "I just wanted to call you. I have a similar video on the foreign server. It should be the distribution room in the parking lot. A man and a woman were sitting on the ground, and the God of Death Mask played a loving game with them. The time is up, and I will kill them. I will send you the screenshot."

Zuo Luo looked at his phone and gave it to the forensic doctor. The forensic doctor watched the video and nodded: "It's them."

Zuo Luo asked: "Where is the IP address?"

Su Cheng said, "I don't think I can find it."

Song Kai said: "The IP address is an Internet cafe. I asked the nearby patrol police to check it, but I don't think it's trustworthy."

Fang Ling went upstairs and reported: "Zuo Luo, the surveillance showed a black car parked at the door of the villa at the time of the incident and left about ten minutes later. The security guard reported that the door had an alarm lock, which was opened normally. In other words, the suspect knew the password of the door."

Zuo Luo looked at the screenshot of his mobile phone and checked the license plate. The car owner appeared, the man who was shot in the parking lot. The suspect killed a man and a woman in the power distribution room of the parking lot, then drove their car to the villa, opened the security password lock, entered the villa, and killed the young couple.

The forensic doctor answered the phone and said, "A shooting occurred in the back alley of the pou bar in the diplomatic district."

Everyone looked at Zuo Luo together, Zuo Luo murmured: "So arrogant?"

Su Cheng said: "No, it should be planned. No, you can be squatting in the parking lot, and you can sneak into the villa, but the back alley of the bar? Are you passing by?"

...

In the back alley of the bar in the diplomatic area, the deceased was an American man. Judging from his clothes, he should have been drinking and going to the corner of the back alley to be intimate with his girlfriend. The location he chose was between several large trash cans. The difference was that there was no video this time, and only one person died. The person who called the police was a girl of American nationality.

The girl said that they were very familiar with this bar. After drinking a few drinks, they arrived at the back alley and wanted to feel the alternative love. A death mask wearing a raincoat took a pistol and walked up to them, and then gave them five minutes to make a decision. Whoever said that she didn't want to die first, then the other party would die.

The answer is obvious. The girl said she didn't want to die, and she said it from the beginning, and then the man died. The girl was in pain and fearful. She watched the death mask leave with a black car at the entrance of the alley, and then she thought of calling the police. At the same time, the patrol officer also found a car five kilometers away. There were too many blind spots in the diplomatic area, so there was no value of surveillance pursuit.

The car abandoned by the murderer was the car of the man killed in the parking lot.

Four hours later, two and a half couples were shot to death. This is an unprecedented vicious murder case in City A, and the arrogance of the murderer's crime is unheard of. The director instructed in the middle of the night that the case was led by one group, seven groups cooperated, and three groups provided full technical support to capture the murderer in the shortest possible time.

It sounds very likely. Logically, the more times the murderer commits crimes, the shorter the interval, the higher the chances of being caught.

But Su Cheng objected to this view.

Another night made Su Cheng feel bad. Although he did not reach his best condition, Su Cheng still analyzed the current situation.

Su Cheng moved with his mouse and clicked on the large screen of the TV: "Nancheng District Parking Lot - Little White-Face Villa - Diplomatic Bar. It looks like a very rampant crime, but in fact the murderer is very organized. The parking lot has a distribution room, the parking lot is on the second floor underground, and the distribution room is more remote. The nature of the parking lot and the villa are different. The parking lot has a robbery nature. The murderer needs a vehicle, otherwise the game location can be set in the car. It is not for the purpose of playing games."

"The villa with a young face cannot escape this place, and you can come anytime. The murderer got the car, even if he was discovered soon, in fact, the body of the parking lot was found soon, but the police followed the procedure and had not started the vehicle pursuit. The murderer arrived at the villa and killed the couple. At this time, the murderer drove to the diplomatic area. Why? I personally think that the murderer had no target in the diplomatic area. Look at this line. Because the diplomatic area is more sensitive, the surveillance is very sparse. It can be said that it is the best place for cars to avoid cameras. I think the murderer went to the diplomatic area to abandon the car. Purpose 2. Confused the police, and happened to find a couple who could confuse the police investigation. This game is simpler, and it determines life and death. The murderer did not prepare for this murder very well."

Song Kai and Su Cheng finished speaking and said, "From a technical analysis, the murderer has a helper. The murderer transmits dv to the designated person during the movement, and this person uses his technology to post videos on the Internet."

The director looked at everyone and asked, "Motivation."

Everyone should look at Su Cheng first, and Su Cheng shook his head: "I'm not sure, is it really for the purpose of killing the loving couple?"

Zhou Duan said: "We can eliminate the possibility of robbing money, robbing sex, etc. Unless we are crazy, we must have motives for committing crimes."

The bald head of the second group is an expert in criminal behavior and expressed his opinion: "I think it should have something to do with love. Judging from the murderer's right to choose the deceased, the murderer has the idea that one person wants to give up his life and save another person. In the current three cases, the first two couples died, and the girl in the third case said that she did not want to die. From this point of view, I think the effect of the crime did not meet the expectations of the murderer. With the spread of the video, the murderer's concept will be spread, and in the next attack, there may be a scene of survival and death of the couple. The murder will not stop and will continue."

Director: "What do you think?"

The bald man thought for a long time and said, "I think the murderer is looking for an answer."

The director asked: "Where are the three groups?"

The three groups are gun-related groups: "It has been verified that this batch of guns is not equipped with domestic 67. Due to historical reasons, in order to support the proletariat and support Vietnam to combat the invasion of the US, the arsenal of the two is different..."

"No need to mention the details." said the director.
