Mystery Tracker 3

Tao Tao's words were like a bomb, which exploded the interrogation room.Everyone's eyes were widened by the news, and the excitement brought about by solving the case just now had disappeared without a trace.Shen Yan raised his foot and wanted to walk into the interrogation room, but Cheng Jinsong grabbed him: "Don't worry, let's see what Director Xiao has to say."

Xiao Changhe is also an experienced old policeman. After hearing Tao Tao's statement, he did not show excessive surprise, but said: "Terrorist action? How can I believe that what you said is true?"

"Director Xiao, I believe you also know that I am the actual manager of 'Freedom East'. On 'Freedom East', there are tens of thousands of discussions every day about how to commit crimes and terrorist activities. What do you think of my news? Will it be reliable?"

"But the problem is that there are always more people bragging than telling the truth online. How can you be sure what they say is true?" Xiao Changhe didn't fall for it.

"Director Xiao, are you using aggressive tactics?" Tao Tao asked with a smile.Xiao Changhe also smiled faintly: "If you want to negotiate terms with me, you must have some sincerity so that I can believe what you said is true, otherwise why should I negotiate terms with you?"

"Okay, what you said makes sense." Tao Tao glanced at Xiao Changhe's left wrist, "What time is it?"

"11:50."

"Then I will give you five hours." Tao Tao said, "Give me to the South Korean embassy, ​​and I will tell you all about the action. After this time, I am afraid it will be too late..."

When Xiao Changhe walked out of the interrogation room, everyone surrounded him immediately. Cheng Jinsong was the first to speak: "According to Tao Tao, the time of the terrorist act was about 17:10 in the afternoon. It is now 50:6, and we still have about [-] hours left." time."

Xiao Changhe nodded—when Tao Tao asked him the time just now, he deliberately said the time an hour earlier, thus buying an extra hour for everyone.However, even so, time is still very tight.Xiao Changhe looked at Shen Yan: "Shen Yan, do you think what he said is true or false?"

"When we interrogated him for the first time in City H, he said he wanted to find a leader." Shen Yan thought for a moment before speaking, "At that time, I felt that he didn't seem to make the request casually. And Tao Tao knew that our Chinese police were Investigate him, he has ventured into China at this time, I think he is cautious, and there is a possibility that he will have a backup.”

Xiao Changhe frowned.He looked at the others again: "What do you think?"

"Shen Hao has read everything in Tao Tao's computer before," Cheng Jinsong said, "It is true that there are a lot of information about killers, mercenaries and criminal groups in various places stored in his computer, but he did not see What specific criminal plans are there. However, we have not cracked his 'Freedom East' dark web account, so we still have no way of knowing what he has done on the dark web."

Xiao Changhe frowned, he thought for a while, and then asked: "If what he said is true, how sure are you that you can pry his mouth open in six hours?"

No one answered.Tao Tao is really too cunning, he is cautious and thorough in his work, and he rarely leaves any flaws, especially when time is so tight, no one dares to make such a guarantee.

Xiao Changhe was also aware of everyone's difficulties. He paused and said, "In this situation, I have to report to my superiors. But I believe you also understand that the best way to deal with this matter is for us to figure out the terrorism. Otherwise, once we agree to Tao Tao’s conditions and hand him over to the South Korean police, your previous efforts may be in vain.”

In fact, there is no need for Xiao Changhe to say this, everyone understands it.The reason why Tao Tao wants to hand himself over to the South Korean police is because he knows very well that once he is tried in China, he will undoubtedly die; but if he can return to South Korea, there may be a glimmer of life. After all, Tao Tao is in South Korea. He did not commit a felony such as murder in the territory, and with the information and money he obtained on the dark web, it is very likely that he will reach a certain deal with the South Korean police to save his life.And if that is the case, it means that half a year's hard work of everyone in the criminal investigation team—even the 20 years of hard work of the older generation of police officers such as Wang Ju—will be in vain...

"Ju Xiao," Shen Yan said again at this time, "We will definitely do our best to find out the terrorist act he mentioned."

"it is good."

Xiao Changhe nodded, and then left first. After he left, Shen Yan said with a serious face: "Call everyone and start a meeting immediately."

meeting room.

"I believe everyone understands the current situation," Shen Yan said with a serious face, "We only have 6 hours now, and we must use these 6 hours to figure out what the terrorist actions Tao Tao said are, and stop them from happening." It. Just now I had a phone call with the horse team in H city, and the horse team has also learned about the situation. Since Tao Tao has mainly been active in city H since he came to China, the target of the terrorist operation is also likely to be in city H, but we cannot Because it’s easy to take it lightly.” As he spoke, he looked at Cheng Jinsong, “The forensic evidence focuses on investigating Tao Tao’s computer, especially those criminals he is familiar with, making a list and handing it over to the customs to find out who has recently arrived in the country. As for For serious cases, we must find a way to pry Tao Tao's mouth open. After a while, everyone will be interrogated in groups and take turns to interrogate Tao Tao. If we can get one more piece of information, we may have more chances."

"Okay." Everyone nodded together.

"Comrades," Shen Yan finally concluded, "Wang Ju and the others have worked hard for 20 years to catch this murderer, and it took us more than half a year, after several failures, to hold him here. If this If we lose a battle, not only will all of our hard work be wasted, but what is even more frightening is that we will put innocent people in danger. Therefore, whether it is for the people behind us or ourselves, we must This battle has to be won—do you understand?!"

"Understood!" Everyone answered loudly.

"Okay, everyone, come on!"

While Shen Yan led everyone to the meeting, Director Xiao also reported the situation to the provincial and municipal leaders.Provincial and municipal leaders attached great importance to it. Director Hu of the National Security Bureau personally led a team to the Municipal Public Security Bureau.

"How much has the suspect confessed?" Hu Ju asked Shen Yan's first sentence, "Time, place, number of people, scope, what can we determine?"

"He only claimed that the time will be about 6 hours later, and he didn't say anything else." Shen Yan replied, "Also, we are still not sure whether what he said is true or not."

"This is easy to handle. We brought a polygraph here." Hu Ju said and looked at Xiao Changhe, who nodded: "The suspect is in the interrogation area, you can go there now."

What Shen Yan didn't expect was that the polygraph expert sent by the national security was actually Xia Nan.Although the two of them were not overly jealous when they met, they also lacked the usual exchange of pleasantries.Xia Nan installed all the equipment together with his partner without saying a word, and then said to Shen Yan: "Captain Shen, it's not that I can't trust you, but my partner and I will have a better understanding in polygraph detection..."

"It's okay, I understand."

Xia Nan nodded, and walked into the interrogation room with her partner.Shen Yan watched the interrogation in the observation room outside with Xiao Ju and Hu Ju.

Seeing the police take out the polygraph, Tao Tao's expression was a little surprised at first, and then he showed a knowing smile.He looked at the single-sided glass next to the door, as if he wanted to see Shen Yan's expression at the moment behind the glass.

Inside, the interrogation quickly begins.

"Name."

Tao Tao did not speak.

"Name." He asked again.

Tao Tao still did not speak.

Seeing that the other party didn't speak, Xia Nan didn't seem surprised. She changed the way of asking: "Your name is Tao Tao, right?"

……

"You currently hold Chinese nationality, right?"

……

Xia Nan asked Tao Tao several questions in succession, but Tao Tao didn't answer from beginning to end, but just stared at the direction of the one-way glass, slightly raised the corners of his mouth, looking quite relaxed.However, in contrast is Xia Nan's side. From the beginning of the question, Xia Nan's partner who was in charge of staring at the electronic screen had a bad expression. Just now, he whispered something to Xia Nan in a low voice, and then Xia Nan His expression also became very serious.Anyone can see that the effect of lie detection is not ideal.

"Has this Tao Tao received polygraph training?" Hu Ju asked Shen Yan.Shen Yan shook his head: "I don't know."

Hu Ju's expression instantly became more serious.Polygraphs detect polygraphs based on heart rate changes in different states. This method is not 100% effective. People who have received relevant training can deceive polygraphs by adjusting their heart rate and changing the baseline.Judging from the expressions of Xia Nan and the others, Tao Tao obviously has experience in this area.

"Officer, let's save these boring games." At this moment, Tao Tao in the interrogation room said, he looked at the single-sided glass on the wall, and said with a smile, "Officer Shen Yan is over there." ? So, you let him in."

All eyes were on Shen Yan.Shen Yan's eyes were calm, and he looked at the two directors: "Xiao Ju, Hu Ju, let me go in."

Xiao Ju and Hu Ju exchanged glances, then nodded: "Okay."

Shen Yan walked into the interrogation room.Seeing him appear, Tao Tao twitched his lips in satisfaction.He looked at Shen Yan, smiled and said, "Officer Shen, do you dare to play a game with me?"

"what game?"

"You wear this thing like me, and we both ask each other questions, and all questions can only be yesorno—that is, answer with yes or no. As long as you answer me truthfully, I will answer honestly too Your question - how about I give you five chances?"

"Okay." Shen Yan agreed without hesitation.

"Happy." Tao Tao smiled a little bit.He glanced at Xia Nan and signaled Shen Yan to put on the equipment.

Shen Yan walked towards Xia Nan, who frowned and warned Shen Yan in a low voice: "Captain Shen, you..."

"Time is running out, this is the fastest way." Shen Yan said in a low voice, then stretched out his arm, signaling Xia Nan to wrap himself on the monitor.

Xia Nan looked worriedly at the one-way glass on the wall, but there was no movement there. It seems that the two leaders also acquiesced to Shen Yan's approach.Gritting her teeth, Xia Nan had no choice but to wrap Shen Yan up for testing.

The two sat face to face, and the display screen of the lie detector was placed between them.Tao Tao smiled and said, "Captain Shen, to ensure accuracy, let's warm up first: Are you Shen Yan?"

"Yes." Shen Yan replied.

A line was drawn on the monitor, which was Shen Yan's baseline heart rate when telling the truth.

On the other side, Shen Yan also said, "Is the terrorist act you mentioned true?"

"Nonono, Captain Shen, you're running ahead." Tao Tao smiled and shook his head, "But I can give you a chance—yes."

What appeared on the screen was a line close to Shen Yan's data - what Tao Tao said was also the truth.

"Then let's lie again—will you let me go?"

"Yes." Shen Yan said.The value on the display instantly soared.Tao Tao laughed "haha", and then replied: "I believe you will succeed."

Tao Tao's value also increased instantly - his lying baseline has also been determined.

Tao Tao seemed very satisfied with the result, so he smiled and said to Shen Yan: "Then Captain Shen, our game will officially begin..."
