The United States, Japan, and many other European countries allow private investigators to exist and have business licenses. Detectives www.biquge.info have no privileges, some governments will train private detectives, and some private detectives can only conduct private training. General courses include: observation, memory, thinking, inquiry, polygraph, stalking, waiting, eavesdropping, secret shooting, technology, science, self-defense, etc. In addition, detectives from Japan, the United Kingdom and other countries can investigate criminal cases without hindering police investigations.

From a legal point of view, the police do not have the right and duty to investigate civil cases, and private investigators fill this gap. For example, if someone scolds you, you can sue in court, but the police will not help you investigate the case, according to the principle of who presents the case in a civil case, you must come up with evidence to prove that the other party scolds you, at this time, what you can't do, a private detective who is no worse than the police can help you do it. If there is no private investigator, you are scolded, and you are scolded, because you will not investigate the case. Scolding is purely an example, in fact, some people have no choice but to endure many things because they have no channels to hire professionals.

Most of the business of professional detectives is family and commercial cases, and retired police officers like Big Pineapple have rich criminal investigation knowledge and unique thinking and reasoning skills. Domestic private detectives are actually very good, they have a lot of black technology, but they don't have legitimacy, and there are a lot of scammers, and the quality of the industry is uneven, so I won't discuss it here.

For example, the big pineapple is no longer called a private detective, but directly called a detective, and usually these detectives have specialized and unique abilities. There is a saying in the industry, German technology, British eyes. German senior detectives carry at least 30,000 euros of equipment every day, and satellite positioning monitors, digital video recorders, camouflage equipment, etc. are all standing equipment. Some companies even rent spy satellites to conduct investigations. Among them are former members of the CIA, former members of the FBI. The British were relatively antique, less technical than the Germans, and they relied more on their own abilities.

Detectives naturally have a very high income, such as a former West German ace detective, who is employed by a federal insurance company, with a basic salary of more than 10,000 euros, and a 7% commission for every money recovered. That's the price a few decades ago. At present, because there are too many employees, there are 50,000 more private detectives than police officers in Germany, but the average monthly income can reach seven or eight thousand euros. The business is very wide-ranging, ranging from the state's principles and policies, diplomatic cards, and partisan disputes, to the murder of people and the theft of goods, stealing chickens and dogs, and so on. As for the business field, it is the specialty of private detectives, such as product development, market competition, enterprise mergers, economic fraud, anti-counterfeiting, anti-dumping and so on

A police officer is a job, a detective is a high-paying job, and aside from other aspects, sometimes a detective is better than a police officer in terms of professionalism.

But Su Cheng didn't blow it either, after all, this is Department Z, because private detectives are not legal, and there is no outflow of criminal investigation elites. Su Cheng doesn't think that his comprehensive ability is better than anyone else, but the professional requirements of private detectives and criminal police are different. Su Cheng thinks he has something special. If the police can't find something, they may not find it. Su Cheng can only trust Xu Xuan now to see clearly, who let this girl bite Qingshan to death and not relax.

Having said that, Xu Xuan is very good in prison, and after being released from prison, he and he went to Europe to open a private detective husband and wife file to ensure that the wealth is rolling.

……

The police installed spotlights on Xu Xuan's running route, which clearly marked Xu Xuan's movement trajectory. Because it was already early in the morning, the police suspended the large-scale search. Even worse news, it's starting to rain in the sky, and it's going to get heavier and heavier, probably until dawn.

Su Cheng put on a raincoat in the trunk of the car, got out of the car with Fang Ling, and walked to the location of the chicken farm first, although the scene was damaged by heavy rain, Su Cheng could smell the smell of the chicken farm. Su Cheng imagined Xu Xuan stepping over the car, the other party suddenly turned around and pulled out a gun, Xu Xuan rolled to the side of the road, and his whole body was covered with chicken feathers and......

Su Cheng walked to the intersection in front of the chicken farm and stood, here Xu Xuan chose to chase to the left, and Sinan chose to the right, this is also where Xu Xuan saw the gangster's firearms......

"Why did the gangster choose this position to draw his gun?" Su Cheng didn't wait for Fang Ling to answer, and said to himself: "The gangster hesitated at this fork in the road, which means that the gangster doesn't know where the fork in the road leads. Standing here, the front is in a straight line, not suitable for escape. Right...... There is a big tree on the right, on the side of the street, which is not a good way to escape. Gangsters can only choose the left. ”

Fang Ling asked, "Su Cheng, what are you analyzing this?"

Su Cheng replied: "The gangsters must have a motive for abandoning the gun. When it comes to escaping, the best motive is the environment, which makes him want to give up the gun or forces him to give up the gun. This is a murderer who has committed at least two or more crimes, and there is only one policeman who pursues him, and he must have abandoned the gun for a purpose, and it will definitely not be to frame Xu Xuan. Let's keep walking......"

This section of the road was a dilapidated dirt road, and Su Cheng walked all the way to the scrap shop. The acquisition store was lined up, and Su Cheng entered the acquisition store, no longer taking the light route, but walked forward, passing through the store. There must be a road lined up, and there is a two-way lane in front of this piece of shop and the cold storage in the distance. It is a road for transporting waste and frozen products.

Su Cheng returned to the light line and said: "The gangsters are not familiar with the terrain, and they are being chased again, so they didn't think of going to the highway in the first place...... He continued to run forward. ”

Su Cheng walked, looking slowly left and right, and there were police officers with police dogs searching here. Fang Ling accompanied Su Cheng and did not disturb Su Cheng.

Su Cheng walked through a storefront, went to the second storefront, walked about ten meters, looked in the direction of the road, didn't see the road, Su Cheng said: "Fang Ling, you go and ask the workers a question, whose car was parked in front of the store at that time." ”

Fang Ling stepped aside, the headset contacted the criminal police, and the criminal police who recorded the confession asked the worker according to the phone number, and about five minutes later, Fang Ling said: "Only a small truck was parked in front of the third storefront. ”

Su Cheng said: "You go to the first storefront and run to the third store, as if you are a suspect." ”

Fang Ling didn't say anything, and walked towards the first storefront, and Su Cheng walked towards the third storefront.

At Su Cheng's prompting, Fang Ling began to run, attracting the attention of many people, because of the ventilation, there was no door between the stores, and Fang Ling quickly arrived at the third storefront. Su Cheng looked at the time, about two hundred and seventy meters, 30 seconds, considering the physical exertion of the two, it should be between thirty and forty seconds. That's a long time, enough for the suspect to think.

Su Cheng said: "So the suspect felt that he couldn't run like this anymore, and when he arrived at the third storefront, he still didn't find the road, but he saw a small truck parked on the road." This tells him that there is a better escape route. ”

Su Cheng walked to the position of the small truck, walked about twenty meters, squatted, and in front of him was a thirty-centimeter step, Su Cheng said: "Fang Ling, give me your mobile phone, you go over there, run here quickly, hook your foot on the steps, and throw out the gun in your hand." ”

"Why?" Fang Ling asked.

"Are you asking why you did it, or why you?"

Fang Ling looked at Su Cheng for a while, pushed to the light line, took out the pistol, and rushed towards Su Cheng, Su Cheng took a picture with his mobile phone, Fang Ling hooked the steps, the person was lying on the steps, and the pistol slid out for several meters. Su Cheng said: "Get up and run diagonally towards the light line." ”

Fang Ling propped his hands on, turned around and ran over the abandoned tire mountain, and soon entered the light line.

"A man races against a woman, and the woman suffers in terms of physical strength, and this man is not as elegant as me and does not like to torture the body. He was very far away from Xu Xuan before, but after the third store, he was slowly caught up by Xu Xuan...... The reason was that he was injured. Su Cheng snapped his fingers.

Su Cheng stood up in front of Fang Ling, who was panting for breath, squatted down, touched Fang Ling's legs, and his pants were worn out at the knee position: "Hehe, the suspect didn't have a knee injury caused when he turned around and knelt on the ground and was shot, but fell on the steps." ”

Fang Ling said: "Looking for a gun, how did you have a mother-in-law?"

Su Cheng said: "There is an open space on the steps, if there was a gun, it would have been discovered a long time ago." ”

Fang Ling didn't believe it, called the nearby police, brought a spotlight, and searched for ten minutes without finding a pistol. Su Cheng called the command center: "I need support from the physical evidence team. "At this point, there are all kinds of possibilities, first of all, it is necessary to prove from the physical evidence that the suspect's running route is like this, and the fall will definitely leave something behind.

The physical evidence team arrived an hour later, Su Cheng explained his thoughts to the leader of the physical evidence team, and the leader of the physical evidence team nodded, checked the scene, and asked Fang Ling to stay, because Fang Ling had polluted the scene and needed to be eliminated. Soon there was good news, the leader of the physical evidence team found an unusual scratch on the cement steps: "Consultant Su, I think you should be right, this should be a firearm hitting the ground, leaving something behind, it should be baking paint." However, according to physics, the pistol should be in this open area, within visual range. ”

Su Cheng said: "One possibility is that the suspect got the pistol back, but it is not scientific. I just contacted the medical examiner, and the medical examiner said that the suspect's knee injury was quite severe. He fell, was wounded, and was about seven or eight meters from the pistol. He went to get the pistol and ran back to the light route, which was too long. At the same time, I wondered why he didn't run to the pistol, take the pistol, and run down to the pickup truck? Why did he turn back to the light route. ”

The leader of the physical evidence team said: "Consultant Su, we have to prove that your inference is correct first, which may take a few hours, or even more than a dozen hours. ”

"Well, of course, in addition, this open area is also looking for any evidence. I contacted the police and asked for a confession. ”

In the third storefront, there were five workers at the time, two of whom were at the end of the store on the light route, and three were unloading and sorting at the rear of the pickup truck. At the time of the incident, the cargo was almost unloaded, and they did not hear any other movements. The three of them returned to the shop together, and they didn't see any pistols or anything unusual in the clearing. The driver of the pickup truck was in the bathroom on the other side of the road, smoking on the phone, and did not notice anything unusual. The two workers in the store did not notice anything unusual except for seeing the suspect and Xu Xuan chasing.

According to the driver, his driver's door was not closed, so why didn't the suspect take the pistol, rush to the car, and drive away? Su Cheng couldn't figure out this contradiction, unless his head hit the floor......

Zuo Luo answered the phone in the middle of the night, with a very good attitude, without the anger of disturbing his sleep at all, quietly listened to Su Cheng's introduction, and asked, "There was no one at the door at that time?"

"Nope. ”

"Is the door open?" Is the door visible from the place of the fall?"

"Yes. ”

"Then why didn't he pick up the gun and grab the car?"

"This question is also strange to me. ”

"What about the news from the Evidence Unit?"

"They are collecting all kinds of physical evidence and they want to bring it back for analysis. It is not yet possible to determine whether the suspect fell here. ”

Zoro said: "You don't want to ask me why the suspect didn't rob the car, right?"

"No, the physical evidence team is almost finished, and I want you to put pressure on them through the Horse Bureau and the director...... The number of people on duty is too small, and the instruments are too busy, so it is better to recruit another technical team. Su Cheng said: "If you fall nearby, you just need to prove that the pistol fell out, and the focus is on the test report of the pistol falling out of the open area." ”

"Okay, got it. ”

Su Cheng hung up the phone and asked Fang Ling to call: "Lu Yi, I'll look for Xu Xuan." ”

After a while, Xu Xuan's voice came: "Hey." The voice was a little muffled.

Su Cheng asked: "You were chasing the suspect at that time, did there be many distance changes?"

Xu Xuan thought for a while: "Yes, the first time was in the alley, I was about to lose his trace, he stopped at the intersection and pointed a gun at me." When I chased it again, I lost my track. Chasing all the way to the acquisition store, it seems that he is hesitating which way to run. After entering the buying shop in pursuit, he threw me far away, half relying on my feelings, half listening to voices, and the guidance of workers on the road. ”

"What about the third storefront?"

"His speed has dropped significantly. ”

"Okay, it's okay. ”

Xu Xuan asked nervously, "Su Cheng, how is it?"

Su Cheng said: "I think it's good that you don't want to be a policeman." ”

"Seriously. Xu Xuan was dissatisfied: "Burn your eyebrows." ”

Su Cheng replied: "I have cracked why you caught up with the suspect, why the suspect abandoned the pistol, and determined the location of the abandonment of the pistol." ”

Xu Xuan was overjoyed: "I knew you could do it." ”

"But I didn't find the pistol. Su Cheng listened to Xu Xuan's silence and said, "Don't be in a hurry, as long as you prove that the suspect once had a pistol, your testimony will be established." ”

Xu Xuan said: "Not enough, this is a firearm, and it can't flow into the black market or some people." The one who dares to take a gun will not be a good person. ”

"You think so much, will you invite me to dinner?"

"No problem. Xu Xuan's tone was a lot more relaxed.

"Okay, I'll take a look. Su Cheng asked, "If I switch identities with you one day, will you choose to believe me?"

Xu Xuan replied, "I can trust you, but I can't find evidence to help you with the fact that it doesn't exist." ”

"Hehe, hang up. ”

"Yes. ”

Su Cheng hung up the phone, looked at the night and pondered for a moment, and snapped his fingers that didn't ring much. Fang Ling didn't know what Su Cheng was thinking, he just felt that it wouldn't be a good thing. (To be continued.) )
