Tracking down the suspect who was serving his sentence in the same prison as Shi Xiaoyu and had the file materials artificially modified, and who had been released from prison for five years, Zhang Chunhe and Cui Luyi, who rushed to Liaodong, conducted a lot of comparison work according to the time when the suspect was in prison and the corresponding time period kept by the Liaodong court that year. In the end, a 48-year-old suspect named "Lu Xidong" was screened out for spreading rumors, inciting public opinion, and gathering crowds to cause trouble, resulting in one death and one injury, and was sentenced to 13 years in prison by the court.

The reason why the two finally determined that Lu Xidong should be the person they were looking for was mainly due to the following three reasons.

First, the time and length of the sentence recorded in the verdict kept by the Liaodong Court are highly consistent with the relevant dates in the prison file that was forged.

Since the management files of all prisoners in prisons are based on the meridian of the inmate's time in prison, although the basic information of the inmates has been artificially altered, it is common sense that the date of imprisonment and the length of time they have served their sentences should not have been modified. Because as soon as these two times, especially the date of imprisonment, are also modified, the electronic files saved in the computer will change significantly.

After all, the day-to-day management of archives is automatically controlled by computer programs, and the compilation of programs is based on chronological order. Therefore, no matter which of the prisoners' imprisonment date changes, it will cause the entire file to be adjusted accordingly in the first place. Well, it's easy to be spotted by archivists. It is therefore unlikely that the prisoner will be released from prison five years after his or her sentence has been released without the slightest indication that his information has been altered.

Second, Lu Xidong's age is very close to the memories of prison administrators.

Third, the prison administration recalled that the prisoner's household registration should not be Liaodong, but it is impossible to remember where it was. In the judgment of the Liaodong Court, it is very clear that Lu Xidong's place of residence is indeed not Liaodong but Songyuan City.

With the permission of the Liaodong court, Zhang Chunhe and Cui Luyi copied all the information about Lu Xidong, and then rushed to Songyuan City, where his household registration was located.

After coming to Songyuan City, he contacted the local public security organ, and soon determined that Lu Xidong's accurate information was completely consistent with the information in the relevant materials of the Liaodong Court he brought. Even found the relevant records of Lu Xidong's cross-provincial arrest by the Liaodong police.

As for why Lu Xidong, a native of Songyuan City, went to Liaodong to create such a criminal case with a bad impact, it was not the task of Zhang Chunhe and Cui Luyi's trip, so they did not investigate it deeply. With the cooperation of the local police, they rushed to Lu Xidong's residence as soon as possible, but were told by his family: Lu Xidong had come back once since he was released from prison, stayed at home for less than a month, and had not contacted anyone in his family for five years.

worked hard, was a prison and Liaodong, and finally came to Songyuan City, but the clue was suddenly broken, how could Zhang Chunhe and Cui Luyi be willing?

So he reported to Lin Jia as soon as possible.

"You are doing a survey on the spot. Lin Jia ordered: "Send back the recent clear photos of Lu Xidong that I have at hand, and I will arrange for a face comparison immediately." ”

Because Lu Xidong's archives during his imprisonment in prison have been artificially modified, Lin Jia can't help but suspect that he may change his identity again.

Soon, Zhang Chunhe sent the materials and photos of Lu Xidong from the Songyuan City Public Security System and the Liaodong Court. Lin Jia also immediately arranged for someone to enter the national face comparison system for comparison.

Two hours later, the results of the comparison came in. A total of 53 people with a photo similarity of more than 80% to Lu Xidong were compared from the entire face system.

Because the photos sent back by Zhang Chunhe, whether they were kept by the Liaodong Court or the Songyuan City Public Security Organs, are all photos of Lu Xidong thirteen years ago, that is, old photos of Lu Xidong before he was thirty-five years old. And Lu Xidong, who is now nearly fifty years old, will definitely undergo major changes in his appearance, so he doesn't dare to rashly shrink the comparison range too small, so as not to miss the real Lu Xidong.

Next, if you want to further narrow down the range, you can only rely on the naked eye to do it, after all, a machine is a machine, and it is impossible to reach the human IQ in terms of comprehensive judgment ability.

For a person's appearance, no matter how long it has passed, whether it has been fat or emaciated during the period, even if it has undergone partial plastic surgery, there are several parts that are difficult to change.

The first is the hairline. A person's hairline can be said to have been shaped from birth, and it is necessary to change it unless there is a large burn or scald accident on the head, or a large area of high damage to the scalp on the head. Even those who lose their hair at a young age can only change the hairline above the forehead, and the hairline of the temples will not change at all.

The second is the eyebrows. Anyone who has trimmed their eyebrows knows that even if they pluck out the excess eyebrows they don't like, the traces left behind cannot disappear and can only be covered up with cosmetics.

The third is the relative position of the facial features, or the distance between them, which will not change in any way. This is also one of the most important bases for the preparation of facial recognition system programs.

The fourth is the face shape. It can be changed by plastic surgery, but it is limited to about 35% of the entire face curve.

According to the above four characteristics, after careful identification, three of the 53 people who were compared by the computer face system and had a similarity of more than 80% were screened out.

The similarities between these three people were 81%, 86% and 97% respectively.

However, the final result of the selection was not the person with a similarity of 97%, but the middle-aged man with the lowest similarity, only 81%, named Niu Tao, who was slightly fat.

"Forest Bureau, look. Niu Tao and Lu Xidong's hairlines and eyebrows are the most similar. And the hairlines of the other two have slight differences from Lu Xidong. Song Jin took the photos of the two to Lin Jia and said: "Moreover, Niu Tao's facial features are most in line with the six characteristics that Xiaohui has derived from hearing and distinguishing people." In addition, the figure of this security guard of the Four-Dimensional Research Institute, Niu Tao, was very similar to the suspicious person that Wei Chen found in the surveillance near Shi Xiaoyu's residence. ”

Lin Jia took the information of Niu Tao handed over by Song Jin, and after only one glance, he raised his head in surprise and said, "The Security Department of the Four-Dimensional Research Institute?"

"Yes, also trained and recommended by Roewe Security. ”

"A unit like the Four-Dimensional Research Institute would easily hire someone with a criminal record?"

"Hehe, Forest Bureau, Niu Tao in reality is not Lu Xidong. ”

After being reminded by Song Jin, Lin Jia immediately shook his head and chuckled: "I'm confused." Now that his identity has changed, how can he still have his former criminal record. ”

continued to look down, and the more Lin Jia looked, the more frightened she became.

Niu Tao, high Chinese, married, 45 years old. His ancestral home is Songyuan City, and his current household registration is located in Chengdong District, Jiangjun City. Veteran, party member. He was awarded a second-class meritorious service once and a third-class meritorious service twice.

"Forest Bureau?"

"You go to the Four-Dimensional Research Institute in person, be careful not to alarm Lu Xidong, and see the number of the service unit recorded in the Niu Tao file that he fraudulently used, as well as the time of enlistment and recovery. ”

"What about Roewe Security?"

Lin Jia rubbed his temples and pondered for a while and said: "Don't go for the time being, first Zheng Qianjun, and now there is Lu Xidong, this Roewe company should not be as simple as it seems on the surface." ”

After Song Jin turned around and left for the Four-Dimensional Research Institute, Lin Jia found out the six features that Song Hui could recognize by listening to the sound at that time, and compared them with the photo of Niu Tao in his hand one by one.

The first national character face with a slightly wider jaw conforms to.

The second facial expression has a certain majesty, in line with it.

It's just that if Niu Tao is really Lu Xidong, how can he have the opportunity to give orders if he is fifty years old and has been in prison for less than 18 years?

The third hilum is larger, and the hairline is more backward, which is in line.

The fourth eye is elongated and has crow's feet, which fits.

The fifth is relatively thin and narrowly suitable.

The sixth article is between forty-five and fifty years old, which is so accurate that Lin Jia is a little surprised.

Immediately, Lin Jia brought a photo of Niu Tao to interrogate Shi Xiaoyu again.
