Chapter 135: Latent Fingerprints

"Luo Tian, ​​you are the person involved. What happened? Why did my dad become like this after talking to you?" The deep love between father and son made Han Bing lose his mind and grabbed Luo Tian's collar:

"If you don't make it clear today, we won't even be friends in the future."

"Because the investigation of the suspect so far has been completely influenced by the other party. Do you know what a big blow this is to a policeman?" Luo Tian almost shouted, damn it, what on earth is this?

Man, actually went to great lengths to create all this?

Han Bing let go of his hand and sat weakly on the bench in the corridor of the hospital. He was a little depressed: "My dad is very angry because he has cracked the most cases among all the police chiefs. This record has been since his time."

He has always maintained this since he was a criminal police officer. He once said that the most unbearable thing was that there were cases that he could not solve in his police career and he could not give an explanation. This time, he really encountered this obstacle."

There were some things that Luo Tian couldn't say. He always felt that the other party was here for the Pearl of Asia, and the other lost items were just a foil. Luo Tian also sat down and said, "Han Bing, what is your impression of father?"

people?"

"Strong." Han Bing said, "I can only think of this word in my mind."

"Yes, Director Han is a strong person, but the stronger the person, the worse it is for him to collapse." Luo Tian said: "Strong people also have another characteristic, that is, they will not admit defeat. I believe Han

After the director makes adjustments, he will still start again and will not admit defeat to the suspect, what do you think?"

"Yes, at this time, he will not accept heart bypass surgery at all." Han Bing finally calmed down: "I was too excited just now. Dad must be very angry with me."

"Father and son will never have an overnight feud." When it comes to being angry, he and his father are at odds with each other, and the result is not a happy ending, not to mention that Han Bing just provoked Director Han a little, went in to apologize, and said

After saying sorry, Luo Tian pushed Han Bing into the ward: "You and your dad have a good talk, I'll go back first."

When Luo Tian walked out of the hospital, he was also confused. He originally planned to get married, but now he has postponed it because of the theft of the Pearl of Asia. The other party came to his home and opened the safe, but nothing else was lost.

Because the Pearl of Asia was deposited in the safe of the bank by themselves in the morning, they missed it. Because the bank is not an ordinary place after all, the unknown force in the middle has not moved. After such a long interval, they are

After making the most detailed plan, he finally took action. Perhaps to hide his motives, while taking away the Pearl of Asia, he also took away other people's things. Shao Bing told himself not to pay attention to it. It seemed that he

Already know who the other person is.

Luo Tian, ​​who was full of worries, walked into his car. Just as he sat in the driver's seat, he suddenly felt something wrong in the car. When he turned around and saw the person in the back seat, he was startled: "Xiaoya?

"

Xiaoya was holding her head, looking distressed. She must be the one who should be distressed. She just appeared in her car silently, and the door was locked. Shao Xiaoya raised her head, her expression

Not very good, his face was very pale, and his whole body looked weak. Luo Tian was really frightened: "Why are you in my car, how did you get in? Where is your brother, where is he now?"

Luo Tian had too many things to ask, but Shao Xiaoya looked a little confused. She didn't seem to know better than herself. She just looked at Luo Tian's face blankly, and it took a long time before she said: "Why am I here?

"

"This is what I'm asking you. Okay, let's go back first." Luo Tian first called Cheng Zhen and asked her to go home and wait, and then drove back. This move was naturally because of the previous lessons, although

Shao Xiaoya said before that he had figured it out, but in order to reassure Cheng Zhen, Luo Tian adopted the safest method.

Shao Xiaoya was so confused that she didn't calm down until she drank the coffee brewed by Cheng Zhen. Facing Luo Tian's questioning, she just made a sad face: "I don't know anything. I've been very mysterious recently about the organization's affairs."

I was not allowed to participate. I stayed in the United States alone, but I couldn't find him. Yesterday, he came back suddenly. I could see that he looked very tired. I asked him what task he was doing, but he just didn't speak.

After that, he said that he would cook for me with his own hands. I have liked to eat the food he cooked since I was a child, but after eating, I lost consciousness. When I woke up just now, I didn’t know where I was at all. I didn’t expect that my brother would

He drugged me, why did he send me here?"

"I'm afraid it's to protect you." Cheng Zhen said, exchanging a look with Luo Tian. Shao Bing's move couldn't be more obvious. He didn't let Xiaoya participate in the beginning, just to protect her, and now he sent her away.

Coming here is just to verify that sentence, the most dangerous place is the safest place. Now the police are conducting a thorough investigation, and that group of people probably dare not appear in this city. Shao Xiaoya came here at this time to let that group of people

Unexpectedly, Luo Tian was a little disappointed. He originally thought that Shao Xiaoya at least knew something, but now his wish was in vain.

Cheng Zhen said: "Xiaoya, you stay here first. I will take leave to accompany you during this period. You don't have to worry. I believe your brother will come to pick you up right away."

"Yes, he tried his best to send you here, you can't go against his wishes." Luo Tian said, "Otherwise his hard work will be in vain, so you can stay here with peace of mind and wait for him to come over, okay?

good?"

Shao Xiaoya was very willful, and both Luo Tian and Cheng Zhen were worried that she would run back without authorization. Wouldn't this make Shao Bing's hard work in vain? It was rare that Shao Xiaoya did not overreact, but lowered his head and stared at the floor for a long time.

She raised her head and said, "You are right, I can't let my brother get into trouble because of my willfulness. I will stay here well and wait for him to pick me up." Although she said this, tears had already flowed out, and Cheng Zhen could only

Feeling distressed, he put his arms around her shoulders: "We are with you, don't be afraid."

"Thank you, Cheng Zhen, I used to..." Shao Xiaoya felt more and more sorry for Cheng Zhen.

Cheng Zhen patted her shoulder: "Okay, don't mention the past things again, no one will remember."

Luo Tian couldn't just stay at home. Without Cheng Zhen in the company, he couldn't live without himself. Luo Tian had to take charge of the company. As expected, Director Han was discharged from the hospital and re-investigated the case. When he had dinner with his employees at noon,

Seeing Director Han being interviewed again, Director Han shouted to the suspect and announced that the police had discovered that the surveillance was fake. Luo Tian was shocked and stopped holding the chopsticks in his hand.

Yuan Jie on the other side said: "Director Han is so brave. By announcing such a major matter, isn't it tantamount to provoking the other party?"

"What do you know? This is called mind-attack tactics." Zhang Qiwei said. Zhang Qiwei's statement was agreed by other employees. A female employee said: "Yes, but what Director Han said is also very bizarre. He actually faked surveillance.

And how did the other party do it if they want to change the surveillance images?"

The female employee's words woke up Luo Tian. Yes, in addition to creating fake surveillance images, they must also be replaced. This is also one of the directions that can be investigated. Luo Tian pushed the bowl: "You guys eat first, I

Go make a phone call."

Luo Tian stood on the side of the road and called Director Han. Director Han laughed loudly after hearing this: "Have you thought of this too? After the interview yesterday, we held a meeting and some police officers also brought it up

, since the surveillance picture is fake, there must be steps to replace it. Now we are starting from this point to see if we can find a new breakthrough. Also, what do you think of the dead man’s fingerprints?"

"On this point, I checked the information later. It is impossible to directly apply the fingerprints of dead people, because dead people will not leave fingerprints. This is scientifically studied. Human skin is composed of epidermis, dermis and subcutaneous tissue.

Composed of three parts, fingerprints are the raised lines on the epidermis. Due to human genetic characteristics, although everyone has fingerprints, they are different. Fingerprints are the lines formed by the concave and convex skin on the ends of human fingers. They are human

Naturally formed during the evolutionary process. The first type is obvious lines, which are lines that can be seen with the naked eye. For example, they are transferred from hands stained with paint, blood, ink and other items, and are usually printed on fingerprint cards to become basic information;

The second type is molding marks, which refers to fingerprints found on soft materials, such as candles and clay imprinted by hand contact. What concerns me the most is the third type of latent fingerprints, which should be found at the scene.

That kind of fingerprint."

Director Han said: "That's right, most of the incomplete fingerprints found at the scene are indeed latent fingerprints. These fingerprints are fingerprint patterns formed by the transfer of natural secretions of the body, such as sweat. They are difficult to detect with the naked eye. They are at the scene of the crime.

The most common fingerprint in . Latent fingerprints are often left when fingers first come into contact with oil, sweat or dust, and then come into contact with a clean surface. Although these fingerprints cannot be seen with the naked eye, they can be detected through special methods and the use of some special chemicals.

When processed with reagents, these latent fingerprints can be revealed."

"Because it is a latent fingerprint, it must have oil to form. However, after a person dies, the body's metabolism has stopped and there is no oil secretion, so it is impossible to leave latent fingerprints." Luo Tian said, "So the fingerprints belong to the dead person.

This cannot be justified. It may be that fingerprints are forged. After all, there will be deviations in machine comparison. As long as the fraud rate is high and the range is within the deviation value, it can be deceived." After Luo Tian finished speaking, there was silence on the other end of the phone.

After a long time, Director Han said: "I have never encountered such a situation before. They made fake fingerprints to confuse us, and used fake surveillance images. These are just making us unable to find the real direction and delaying time.

Over time, it will become an unsolved case. Now it seems that a breakthrough has been found, but in fact everything is still in the same place."

Luo Tian suddenly said: "Director Han, I have an idea. I don't know if it's convenient for me to tell you."

"Is there anything I can't say? If you have helped us a lot, and you are the victim, there are only two of us now." Director Han was informal.

"Director Han, have you ever thought about asking Interpol for help?" Luo Tian said: "Judging from the current crime methods of the other party, he is definitely not an ordinary petty thief. This kind of superb crime methods may have been used in other places.

It has appeared before, but we don’t know about it. It may be abroad, or Interpol may have been contacted. Of course, this is only a possibility..."

"No, no, no," Director Han said, "You are right. They are not ordinary thieves. It's just a pity that we need to seek help from Interpol. I'm afraid we have to go through the procedures. I don't know how long it will take. I don't know how long it will take."

Okay, I'll apply right away and hope to get in touch with them as soon as possible."
