Before they had time to enjoy the joy of victory, Song Guyan and the others had to join up with the criminal expert group that came from China and stationed in the special team set up by the American police.

Not every case can be solved, otherwise the police archives would not be stacked with so many unsolved case files. It's just that Wang Keke, as a visiting scholar, happened on the ground in the United States, and the suspect is an American, which has attracted a lot of attention to this case.

Wang Keke's case has stirred up public opinion in both countries and brought tremendous pressure to both China and the United States.

The Metropolitan Police and the F.B.I. were not very friendly to the personnel sent by the Chinese side, and many clues about the case were not released to them. Even if these people are dressed in the skin of Interpol, they are all Chinese police inside. If they solve the case and the American police make no progress, then the slap in the face is too loud. Even if the case cannot be solved, the Chinese side must not be allowed to solve the case.

To put it simply, it's a big deal for everyone to waste firewood together.

The core figure of the Chinese criminal expert is Professor Hao Aimin, a legendary master of solving crimes, and also a senior professor of criminology at the Beijing Police Academy.

Professor Hao Aimin has experience as a grassroots criminal police officer and is an experienced criminal police officer himself. During his career as a police officer, he solved a number of mysterious murder cases, all of which lacked direct human evidence or evidence to make the suspect admit guilt, but Professor Hao Aimin used his superb forensic skills to solve the cases and bring the suspect to justice. During his tenure at the police academy, Hao Aimin told him about his own experience in solving cases, and told him a lot of skills and crimes in investigating and handling criminal cases in practice, which are by no means comparable to rigid textbooks.

When Song Guyan was studying, he didn't have the opportunity to attend the professor's class, so he only took graduate students and criminal police. Song Guyan was fortunate to have listened to Hao Aimin's lectures a few times, and she was his little fan sister.

Professor Hao Aimin's most admired and pursued sentence is "how much evidence is there to say how much", and he will never be easily decided because of superiors and public opinion. In the large number of cases he handled, there was not enough evidence to make it an ironclad case, and he would not sign his name.

It is also strange to say that in the Internet information age, it seems that every netizen has become a detective who has insight into the truth, and thinks that he is more powerful than many senior criminal policemen, and can get the truth beyond the evidence. Even if the police strictly verify and investigate carefully, the conclusions they come up with often do not meet their expectations, and what these people want to see is only the truth they need, and then scold, it is as dark as I thought.

Although he is only in his early fifties, Professor Hao Aimin's hair is already gray, and his roots stand on end, looking very energetic.

The US side did not disclose too much inside information for many reasons, and Hao Aimin was also hot-tempered, so he directly took the published information and found an office to analyze the case.

The people who followed Hao Aimin were all elite soldiers, and they were only organized to sort out the case.

Chen Dongyu and Zhang Shanwen are not good at criminal investigation, and they are confused about what these experts say, but Song Guyan's eyes are shining.

Professor Hao Aimin relied on very few clues and sorted out Wang Keke's case in a very orderly manner.

"There's an FBI suggestion to focus on human trafficking, which seems to me to be almost impossible. The procedure of human trafficking is complicated, and it is necessary to negotiate the next home and the time and place of delivery. In the process of reselling the entire big living person abroad, the FBI will definitely find clues, and so far, there is no information about this. Brandt is not short of money, he has a high salary, and after being arrested, he also hired a well-known lawyer, which also shows that if Brandt is the murderer, then his purpose is not for money. ”

"I think part of Brandt's motive for committing the crime is to satisfy BT's desires, but this is definitely not all of his motives. ”

Most sex kidnappers will place their victims in a hidden place as slaves to vent themselves, and in a few cases, they kill the victim immediately after satisfying the vent. So far, the FBI has not been able to find the whereabouts of Wang Keke, and Brandt has remained silent and has not said a word about the case. If it weren't for the FBI's surveillance of Brant's residence and the fact that he confessed to kidnapping Wang Keke when he contacted his friends, the police might not have been able to arrest him.

Suppose the victim was hidden as a slave and now that the suspect has been arrested, unless someone assists him in caring for the victim, the longer the delay is made, the less chance there is to survive, and it is necessary to hurry, otherwise Wang Keke may starve to death and die of thirst.

Then, after excluding human traffickers, there are only two possibilities left. Wang Keke was hidden in a place that has not been found so far, or his body has been destroyed and destroyed. This is the third day of Wang Keke's disappearance, and it is more than a day before Brandt's arrest. Brandt is an extremely egotistical person, as can be seen from his self-introduction on the website. He basically does not commit crimes with other people's accomplices. You must know that one more person is one more risk of being detected by the police, and such a cautious criminal will not trust anyone. He is the only one in the world who knows Wang Keke's whereabouts, he does not speak, and the police can only rely on the only clues to find the victim.

It is not that the police did not interrogate Brandt, and these videos and written materials are also open to the Chinese expert group and do not have much value.

American law strictly prohibits the extortion of confessions, and evidence obtained through coerced confessions is invalid in court, and even if the truth is annoying, the judge will not admit it. This is also a common conundrum faced by police in the United States, where the suspect is silent and does not say anything, and the police are unable to find sufficient evidence. Many people may not understand the legal environment in the United States, and once there is torture to extract confessions, even if Brant is really guilty, he will be acquitted in court. This is known as "procedural justice", and all interrogations must not violate procedure.

Secondly, it is impossible to be charged with murder if the body is not found. This is also true at home. Even if it is a small piece of human tissue, it can only be charged with murder if it is found, otherwise it will be sentenced to kidnapping at most. There was a murder case in the United States where the suspect did not open his mouth like Brandt, and finally the police found a skull, which was confirmed to be the victim through DNA identification.

Why is it said that capital is a crime, and if you have money, you can hire the best lawyer, and after they collect the money, they can rely on their knowledge and eloquence in the courtroom, beat the plaintiff to lose his armor, and finally let the judge make a judgment in favor of the defendant. Even if you know that the suspect can't escape, you can often be acquitted with the good performance of the suspect's lawyer in court.

There are so many examples of the American police obviously having an advantage, but they have lost a lawsuit, and it is not surprising that they are used to it.

During the FBI's interrogation, he had used money and commutation to induce Brandt to speak, but he pretended to be deaf and dumb and did not reveal a word, which gave the detectives a headache.

It is precisely because Brandt has not opened his mouth that these videos are of little value and will be opened to the Chinese expert group.

After a quick look at the video of the interrogation, the criminal police present fell silent.

During the interrogation that lasted for more than an hour, Brant's expression basically did not change, whether it was a police threat or a temptation, he did not respond, as if he was indifferently watching a boring mime.

Even if he showed some impatience or aggressiveness, it would not make the criminal police so silent. If there is an emotional change, it means that there will be a breakthrough. But Brant's attitude of not entering the oil and salt made them not know where to start.

"Back to about fifteen minutes later, it was played at the same speed. Song Guyan suddenly spoke.

The criminal police officer in charge of the screening was a little surprised, how did the instructor who was watching make a request.

Although it is said to be a team, the trainer is mainly responsible for the search after finding clues, and the audit is just a routine task to let them know some progress of the case. Look at Chen Dongyu and them, although they tried hard to cheer up, they were still a little sluggish, obviously this complicated case could not attract their attention at all.

Hao Aimin nodded and motioned for the police to come according to Song Guyan's request.

The progress bar is locked at fifteen minutes, and the interrogating police officer is trying to reduce the sentence in exchange for Brandt to speak.

"Stop! Song Guyan stepped forward and pressed the spacebar.

The picture froze, and the corners of Brandt's mouth raised slightly, slowly mocking.

"I have listened to Professor Hao's lectures before, and they mentioned the motive for the crime. ”

Hao Aimin motioned for Song Guyan to continue, not because this girl had listened to his lecture, but because she could detect such subtle changes in Brandt's emotions, it was indeed worth listening to Song Guyan's thoughts.

"Professor, you said that in modern society, the motive of crime is different from many traditional analyses, and it is not limited to traditional motives such as vendetta and love killing. Song Guyan said, "Although this situation is still relatively rare in China, it is relatively common in the United States, where urban culture is developed." ”

Notice Brandt's sarcastic smile, let's call it laughter. ”

"For Brandt, who has been silent, making this move is very unusual. ”

"Why is he laughing, why is he mocking the interrogating policeman in front of him?"

"Why?" asked Chen Dongyu in a bit of confusion.

Compared with the terms of experts, Song Guyan said it more easily and easily, so that Chen Dongyu couldn't help but echo it.

Seeing many criminal policemen looking at him, Chen Dongyu shrank back a little embarrassed. Everyone is professional, so the people who eat melons should watch it carefully, and don't interject.

Zhou You quietly looked at the shovel official outfit, and felt a little proud inexplicably.

After all, it's my shovel officer, it's just different, and he can control the whole scene as soon as he opens his mouth.

Although Zhou You didn't see anything from Brandt's ridicule, you were arrested and you were so arrogant, I really don't know how to write dead words.

"These American police officers are using commutations to lure Brandt to speak, and he is dismissive, is it possible to think that he did not think about reducing his sentence at all, or that he thinks that the police have not found clues to convict him? ”

"From the analysis of Brant's behavior, he is a jealous and conceited person. ”

"We can assume that he has been planning this kidnapping for a long time and has decided that the police are powerless. ”

Hao Aimin raised his eyebrows: "What do you say?"

"I go to the perverted website every day.,Recently, I have regularly logged on to the discussion group on how to carry out the perfect kidnapping.,Just to plan the most perfect kidnapping plan in history.。 With Brandt's high intelligence, it is enough to plan a seamless kidnapping plan, including how to avoid surveillance, how to avoid his wife's suspicion, how to deal with hostages, and how to make the strongest FBI in the United States unable to find hostages. ”

When he felt that he had completed the preliminary work, he began to look for the target of the crime, and Wang Keke inadvertently entered his field of vision. ”

"How can it be so mysterious as you say?" a detective retorted, "This is completely your speculation, and there is no evidence." ”

The direction of the investigation is very important, if it is handled as a kidnapping case, then the most important thing is to find Wang Keke, and then rescue the hostages. Dealing with it as a murder case is to find evidence that can give Brant a specific crime. If you go in the wrong direction, you can waste a lot of time.

Based on Song Guyan's inference, Brant deliberately provoked the police and regarded this as a crime game. Starting from this psychology, Brant will never kill Wang Keke, but let the police helplessly wait for Wang Keke to die of thirst and starvation, but the police can't find her whereabouts.

In the eyes of the questioning criminal police, it is more likely that Brant destroyed the body, otherwise it is really impossible to explain that the FBI spent so much manpower and material resources and did not find even a little clue.

Hao Aimin remained silent, no one supported or opposed, but replayed Brandt's taunt over and over again.

"Do you think the arrest process reported by the US side is awkward?"

Several other criminal policemen didn't understand what Hao Aimin meant, didn't he mean Song Guyan's reasoning, why did he talk about arrest again.

Hao Aimin took the document over: "After finding Brant through the vehicle, the police began to monitor, and soon overheard Brant and his friends admitting that they had kidnapped Wang Keke. ”

"Do you think that a high-IQ criminal who hid the police and the FBI with so much manpower and couldn't find it, a jealous and conceited guy, would not know that he would change the vehicle when he was kidnapped?

"Besides, isn't it unusual that a person who doesn't even trust his wife would admit to a friend with an average relationship that he kidnapped Wang Keke?"

Song Guyan nodded slightly. Jiang is still old and spicy, she noticed the small details in the interrogation video, but she has not had time to analyze the whole case in combination. Hao Aimin's perspective is completely fine, and more importantly, he has a good grasp of Brant's psychology.

She was right. Hao Aimin exhaled, "Brandt's most fundamental motive for committing the crime is to provoke the police, and Wang Keke is just an innocent victim." ”
