I am the best in the world with the crime solving system

Lingquan brought back the fingerprints of eight people.

Feng Shoudao, Qian Wen, Zhao Wuwei, Wang Da, Song Yanzhong, old man Sun, and Ma Huai, a judicial historian under Wang Da, and Shen Jimin, a judicial historian under Song Yanzhong.

Eight people, eight sheets of paper.

Each person's fingerprints are individually pressed on a piece of paper.

Chen Chaoyan used her own eyes as a medium to 'scan' eighty fingerprints onto the light screen, then held the deed and Feng Shoudao's fingerprint card, pretending to compare the fingerprints, but actually looked at the light screen.

On the light screen, the eighty fingerprints brought back by Lingquan were arranged in eight rows according to each individual.And with the seventeen lines and 160 three fingerprints on the deed, they are divided into two groups, one left and one right.

It is obviously impossible to compare one by one.

Chen Chaoyan separately extracted 49 fingerprints that she could recognize on the deed, and through zooming in and overlapping comparisons, one of the same fingerprints was crossed out first, leaving 36 separate fingerprints.

then.

She extracted Feng Shoudao's two thumbprints, enlarged them with three of the 36 fingerprints at the same time, and overlapped and compared them respectively.

The fingerprint of Feng Shoudao's right thumb matched one of them.

Chen Chaoyan looked at it, and the fingerprint on the comparison was the loan deed she was holding, and it was also one of the two fingerprints that she had scanned for the first time.

Although it was all thanks to the light screen, Chen Chaoyan was still very happy.Take a pen to make a record on the deed fingerprints that were compared, and circle Feng Shoudao's right thumb on Feng Shoudao's fingerprint paper.

Afterwards, she used the same method to compare Feng Shoudao's other eight fingerprints to get three more fingerprints.

One is the back of the same deed of deed, and the other two are the reverse of the left side of another deed of deed.

Withdrew from the light screen, took the deed and compared Feng Shoudao's fingerprints pretendingly for a moment, and after finishing the records one by one, when Chen Chaoyan was preparing to compare Wang Da's fingerprints, Xie Xuan picked up Wang Da's fingerprints one step ahead of her.Moreover, he also picked up the first loan at the same time.Following her previous actions, he held up Wang Da's fingerprints and the deed, facing the sun that was gradually falling in the west, and asked her: "What is the method of comparing fingerprints, tell me."

Say hell.

She cheats by cheating.

Pointing to him to put the deed and Wang Da's fingerprints on the table, Chen Chaoyan pointed to the bulging stripes in Wang Da's fingerprints, and explained, "See these bulging stripes? These are in the fingerprints. It is called the uplift line in . Like this part of the uplift line that presents fractures and bifurcations, the fracture is called the endpoint, and the bifurcation is called the bifurcation point. The endpoint and the bifurcation point are collectively called feature points. Generally, in this center The position contains about fifty feature points, and if the positions and directions of these feature points are the same, it can basically be determined that they are the fingerprints of the same person."

"Basic?" Xie Xuanji keenly grasped the key words and asked, "Why not certain?"

"Because this is only the position and direction of the comparison, it is inevitable that there will be the possibility of coincidence." Chen Chaoyan explained.

"If there is a coincidence possibility, how should we deal with it?" Xie Xuan asked.

Of course, the connection relationship is used to enhance the accuracy of fingerprint recognition.However, the connection requires the use of instruments, and manpower is not enough.But in order to frighten Xie Xuan, Chen Chaoyan forcibly searched and found out that when she went to the county on business two years earlier, when she was handling a case in a mountain village far away from the town, she asked her colleagues the same question, and her colleagues gave her the answer, explaining to him: "Then It is necessary to compare the number of raised stripes across the feature point and between other feature points."

Xie Xuan picked up Wang Da's fingerprint again, stared at the sun for a moment, then looked back at her, teasing rather implicitly: "It's a pity that Miss Chen doesn't learn riding and shooting with her eyes."

Chen Chaoyan smiled, but did not answer his words.

After he returned Wang Da's fingerprints, he continued to pretend to compare the remaining fingerprints through the light screen.

The setting sun is fading away, and the sunset is all over the sky.

When the last ray of light was about to recede and night gradually climbed up, Chen Chaoyan finally compared all the fingerprints.

only--

The fingerprints on the left and right sides, front and back of the two deeds were all compared.Only the few fingerprints in the middle of the deed are still empty.

"Are you sure you have brought back the fingerprints of those who have touched the loan?" Xie Xuan asked Lingquan looking at the few fingerprints.

Lingquan nodded: "It's all back."

"Looking at the location of the distribution of these fingerprints, it should be left by the person who wrote the deed." Xie Xuan talked eloquently, "According to the rules of the cabinet, the deeds are all from the hand of the accountant. But, just in case One... Lingquan, go get Zhou Zhongcai's fingerprints."

These are not Zhou Zhongcai's fingerprints.

Chen Chaoyan had already used the autopsy video stored in the light screen to extract Zhou Zhongcai's fingerprints and compared them.

But she didn't stop Xie Xuan.

When Lingquan retrieved Zhou Zhongcai's fingerprints, Chen Chaoyan still pretended to compare them, and after denying that it was his fingerprints, he asked: "The loan deed says that it is the Silver Hook Cabinet Workshop, and it is also stamped with the seal of the Silver Hook Cabinet Workshop. , but how many silver hook cabinet shops are there in Luyang County?"

Xie Xuan first ordered Lingquan: "Take the token and go to bring back the shopkeeper and accountant of the Silver Hook Cabinet Workshop!"

After Lingquan took the order to leave, he looked back at Chen Chaoyan and asked with interest, "Why is there no fingerprint of Zhou Zhongcai on the deed?"

"He didn't touch..." Chen Chaoyan was in the middle of speaking, and suddenly realized.

Zhou Zhongcai went to Yingou Cabinet to borrow money, and Yingou Cabinet issued him a loan.According to the normal procedure, the loan deed is in duplicate, and in addition to the seal of Yingou Cabinet, Zhou Zhongcai's fingerprint is also required.But now this lease of loan only has the seal of Yingou Cabinet Workshop, but no Zhou Zhongcai's fingerprint.Not even his fingerprints could be found on the two leases.

Sweat and sebum will evaporate with time, and the lease time was September and November last year, and it has been seven or eight months since then, so it is normal that it cannot be brushed out with powder.

However, two loan deeds were placed on Zhou Zhongcai's suicide case.

And there are traces of ravages.

If Zhou Zhongcai...

"If Zhou Zhongcai hadn't touched the loan, who put the loan on the table?" Xie Xuan asked.

Chen Chaoyan looked at the fingerprints that had been compared, and said calmly, "The murderer."

Xie Xuan asked slowly: "Those overlapping fingerprints that cannot be compared, can you be sure that they belong to them?"

"No." Chen Chaoyan said, "Although they can't, they are undoubtedly the most suspicious."

"Since the suspicion is the greatest, then..."

"Then ask where they were when the crime happened, and who can testify." Chen Chaoyan took the lead from him, "If no one testifies for them in the place they mentioned, then we must investigate them intensively .”

Xie Xuan said: "But you said that there are two murderers."

Chen Chaoyan frowned, "You mean..."

"Since there are two murderers, can they testify against each other?" Xie Xuan asked.

Chen Chaoyan responded calmly: "This is unavoidable. But the murderer knew that I would use blood to solve the case, but he didn't know that I could also use fingerprints to solve the case. In addition, I had already deduced his method of killing, and used it to lie. Maybe catch him off guard."

Xie Xuan suppressed the coldness in his eyes, and asked slowly: "What if you can't catch him off guard?"

Chen Chaoyan looked at him sharply, "What does your lord mean?"

"Judging from the scene of the crime, the murderer did not kill Zhou Zhongcai on a whim, but carefully planned it. If it weren't for Ms. Chen, the process could have been planned perfectly. But nothing happened. , I must have already prepared a countermeasure." Xie Xuan glanced at her, then turned his gaze to the flowering crabapple tree in the courtyard, and said slowly, "Using fingerprints and murder to lie can beat a murderer It's best to be caught off guard. If not..."

"Then continue to investigate." Chen Chaoyan said firmly!

Xie Xuan withdrew his gaze and looked at her, with a gloomy look in his eyes that she couldn't understand, "There are seven of them, one is the sheriff of Luyang County, two are the military officers serving in front of the sheriff, and the other is Sicang of Luyang County who joined the army. , one is the judiciary of Luyang County who joined the army, two are the history of joining the army, and the remaining one is also the governor of the county government."

Chen Chao's face was cold and cold, and he asked with some disappointment: "According to what the prince said, are you going to let them get away with it?"
