Mu Haoran quickly got up from the chair and came to the smoke display cabinet, the back of the switch controller had a horizontal palm pattern and a finger fingerprint clearly visible, they succeeded!

Chen Yanxi hugged Mu Haoran's arm excitedly, and said in an excited voice: "God really gives face, we actually succeeded, this time we have to knock Du Jiang's kid, I helped him so much, it shouldn't be too much!" ”

Mu Haoran used his best strength to make the corners of his mouth slightly hooked, and smiled faintly at her: "Chen Yanxi, you are an excellent criminal policeman." ”

It was rare to hear in his mouth that it was not derogatory to himself, Chen Yanxi was very happy, but what made her even more excited was that she actually saw Mu Haoran smiling, it turned out that the iceberg was also in a good mood, and it was really the sun that came out in the west.

"You look good when you smile, smile more in the future, and exercise your facial muscles by the way, maybe it will have a repair effect on the injured nerves." Chen Yanxi's heart was fluttering by this light smile, and her tone of voice was much softer unconsciously, and it was not as stiff as talking to him on weekdays.

"You have to use the strength to eat milk once you laugh, I think it's better to forget it, I'll go and convene a meeting first, the clue of fingerprints is very important, let go of other things, and leave it to Liu Jie and them!" As soon as she gave her three colors, she opened a dye room to make him smile more on weekdays, she didn't know how tired he was just now to hold back that smile, if he was made to smile all day, it would be better to let him die more happily.

Because the fingerprint handprint shown by the '502' fumigation method is white, and the contrast between the trace on the surface of the light-colored item is too small to be easy to identify, so she dyed the fingerprints and palm prints to increase the contrast between the handprints and the object, so that everyone can see the traces of the fingerprints more clearly.

Li Duo and several other scouts were directly called to the office of the Technical Investigation Department, where Du Jiang was ready to compare the fingerprint information brought back by Chen Yanxi, and everything was ready.

At about seven o'clock, Chen Yanxi came out of the laboratory and handed the data she collected to Du Jiang: "Let's get it, let's start, the fingerprints on the finger part have reached 90%, which is very clear." ”

Du Jiang nodded, put the dyed black fingerprint template that Chen Yanxi brought back into the scanner, and after a few seconds, the photo of the fingerprint trace was transferred to the system and converted into a standard digital image.

The system automatically locates and labels the fingerprint sample to form a standard fingerprint template, followed by a series of refinement processing, and the generated image can clearly see the direction of the fingerprint, and the most significant features on the fingerprint are clearly distinguished.

Through the screening of the database, a fingerprint sample that can be identified in the same way as the sample sample appeared on the computer screen, everyone's excited expressions were very excited, Mu Haoran tapped the top of the desk hard: "Find someone, make sure the family lives, Li Duo is ready to lead someone." ”

"Yes," Li Duo replied.

"The owner of the fingerprint is named Lin Jingwen, 40 years old, a private business owner, and lives in Unit 602, Building 12, Taifeng Garden." Du Jiang retrieved the authentication information of the fingerprint owner from the database.

Mu Haoran, Li Duo and two police officers rushed to the suspect's house to prepare for his arrest, Taifeng Garden was nearly an hour's drive from the Criminal Investigation Brigade, Li Duo turned on the police lights, and arrived at the destination in less than 40 minutes.

But when they walked through Lin Jingwen's home, they were completely dumbfounded, this person became a vegetative person because of a car accident a year ago, and now he has to rely on nutritional injections and nasogastric feeding to eat, and when his family talks to him, he can barely respond occasionally in a blink of an eyeball, how can such a person appear at the scene of the crime, and then destroy the circuit equipment and cause a fire?

In order to ensure the readiness of fingerprint identification, Mu Haoran collected his fingerprints and prepared to go back to do another fingerprint comparison.

On the way back, everyone's mood was not as excited as when they came, they all drooped their faces and looked depressed, Mu Haoran's mood was also affected, he was thinking, Chen Yanxi was busy in the laboratory for several hours, could it be that something went wrong in the test results caused the error?

Although there are often cases of starting over again in the investigation of cases, such clueless cases are the most headaches, and in the face of pressure from superiors and questions from family members, the case-handling personnel are indeed under tremendous psychological pressure.

Back in the office of the serious crime team, Chen Yanyaxi had already been waiting there, seeing that everyone was not in a high mood, she thought that the suspect ran away and didn't get caught, so she said: "What are you doing with your head down, if you don't catch it, you can't get caught, you can run away from the monk, you can't run away from the temple, you can report and issue a wanted warrant tomorrow, now that the public security system has been networked nationwide, where can he go in the past two days!" ”

Li Duo sat in a chair and interrupted her beautiful fantasy: "The suspect didn't run away, he stayed at home honestly, but we couldn't catch him." ”

"Why? Bureau, have you been injured or caught in a fire? Chen Yanxi was a little puzzled, since she had found someone, why did she say that she couldn't catch it.

"If only he had the strength to resist arrest!" Mu Haoran put his hand on his waist and said a little weakly.

"What the hell is going on, if you don't resist arrest, you can't catch it?" She really didn't understand.

Mu Haoran threw the photo taken from Lin Jingwen's home on the table and said, "Look at it yourself." ”

Chen Yanxi picked up the photo and looked at it: "I'll go, what's going on, it's been like this in the past two days?" ”

"It's not for the past two days, this Lin Jingwen has been in a vegetative state for almost a year, how did he go to the crime scene like this!" During the day, he went to visit the periphery, and at night he followed to arrest people, and the investigator Xu He was already a little exhausted, and his voice was a little hoarse.

"Is that my experiment going wrong? Or there is an error in the detection process. Chen Yanxi understood the problem.

"I collected Lin Jingwen's fingerprints and made another comparison." Saying that, Mu Haoran went to the Technical Investigation Department again with the sample materials.

Du Jiang once again compared the materials, and to his surprise, the result was still the same as last time, and the fingerprints that appeared at the scene were Lin Jingwen's.

"How is this possible, he is paralyzed, how to go to the scene to leave fingerprints?" Xu He couldn't believe his eyes, but the data doesn't lie.

"Du Jiang, will there be a problem with the result?" Mu Haoran asked.

"How is it possible, this is the most advanced fingerprint collection and comparison system so far, the police, how can it be wrong." Du Jiang was a little dissatisfied with his questioning.

Mu Haoran didn't want to doubt his colleague's ability to work, but the fingerprint was so strange that they couldn't explain its source, so how could they explain it to the victim's family.

"How can this be, the probability of fingerprint duplication is almost zero, is it true that there is really an identical fingerprint?" Chen Yanxi felt a little incredible, she couldn't explain the problem.

"No, there are no two identical fingerprints in this world, it can only be said that you have met a master, this case seems simple and rude, someone deliberately destroyed the heating facilities and caused a short circuit in the wires, but in fact, the gold content here is much beyond our expectations, the suspect used other people's fingerprints to frame the blame, so as to achieve the purpose of evading legal sanctions." Du Jiang made a bold guess.

Chen Yanxi shook her head violently and said: "Impossible, passwords can be stolen in this world, pictures and even video information can be cost, this fingerprint can't be faked, if you want to say that the fingerprint is almost destroyed, it is all smoothed, how can this fingerprint be stolen, do you chop off that person's finger!" ”

"Why can't you, you can make a finger mask, copy a finger that is exactly the same as the person concerned." Du Jiang believes that this is theoretically feasible.

"I'll go, how high is the cost, in order to kill a child, the price paid is too great, I heard that the kind of Hollywood blockbuster to make a face mold is hundreds of thousands, or even millions, this synthesis of a complete fingerprint information, how much does such a sophisticated thing cost? Cui Yuqing is just a little girl who is still underage, she has no power, no power and no money, is it necessary to kill her with such a high investment? Li Duo couldn't believe that someone would pay such a high price for killing such an ordinary person.

"That's right, the price is too great!" Chen Yanxi also echoed, she didn't believe that anyone would be so desperate to kill such a defenseless little girl.

"Everyone, I can't help you with this, it's your investigator's business to find the motive for the killing, can you go back to your office to study, I just gave you a way, the fingerprints at the scene appeared, theoretically there is only one way.

You'll have to find out for yourself what the hell is going on, so don't mess around with me, okay?"

"I have carbon monoxide in my place. In other words, there are too many of you, and the harmful gases released have seriously affected my breathing, so let's go back and study it. There were so many people around Du Jiang's desk, which was less than five square meters, and he felt that his eardrums were about to be burst, and he began to give an eviction order.

"Hey, let's go, I'll bother Liu Jie to see if there are any clues in his side of the surveillance, I think it's much easier to find that one than to find this finger, although that one is looking for a needle in the haystack, but there is always a goal, it's better than you don't even know where to catch your finger."

Li Duo teased the mysterious fingerprint that appeared unexpectedly, but he also knew that the mysterious man who appeared at the scene was also a problem.
