Chapter 16 Review
In the early morning in Ningtai County, there is still a trace of mist.
Jiang Yuan rode an electric bike into the yard of the Criminal Police Brigade, his arms already a little wet.
"Morning." A passing police officer smiled naturally at Jiang Yuan.
Jiang Yuan was stunned for a moment and quickly replied: "Morning."
This was the first time that he was greeted on the street after being at work for so long. The policeman who greeted him looked familiar, but Jiang Yuan did not expect his name and unit.
Shaking his head, Jiang Yuan turned around and entered the building. Two more people in the middle nodded and said hello.
Although everyone was in a hurry, Jiang Yuan's mood became happier unconsciously.
Entering the office, Wang Zhong and Yan Ge were already sitting inside.
"Forensic Doctor Jiang can do it. He can hide it deeply." Yan Ge praised loudly, and also used the title of Medical Examiner Jiang. To be honest, this was much more respectful than Xiao Jiang.
And in a place like the local police force, where there is no money, no power, no promotion, respect is the most precious thing.
After listening to Yan Ge's words, Jiang Yuan immediately realized that the suspect in Liu Yu's injury case arrested yesterday must have had results.
"Have you caught the person? Have you reviewed it?" Jiang Yuan looked over expectantly.
"Caught the person. If you want to recheck, take a look for yourself." Yan Ge directly handed several fingerprint cards to Jiang Yuan.
When Jiang Yuan matched the fingerprints of the "Liu Yu Injury Case" yesterday, first of all, he made many fine-tunings. Secondly, he only marked 8 feature points, so a review was needed.
According to regulations, the eight characteristic points that are the same are only the standard for investigation. In other words, if the fingerprints have eight characteristic points that are the same, for the criminal police team, it can be considered a win, and they can arrest, conduct interrogation, approve arrest warrants, etc. wait.
However, to enter the litigation process and use fingerprints as evidence, a fingerprint identification certificate must be issued. The minimum requirement for a fingerprint identification certificate is that 13 feature points are the same, and there are no exclusions.
However, now that there are real people around, it is easy to compare fingerprints.
After all, the quality of the printed fingerprints itself needs to be scrutinized. On the other hand, no matter how good the fingerprint is, it is impossible to reveal all the details of the fingerprint.
However, if there are real people around, and if you do a few more seals, the details will naturally be more comprehensive. It is obviously easier to do the reverse operation and use the fingerprints re-stamped by real people to match the fingerprints left at the crime scene.
Jiang Yuan took the fingerprint card, glanced at it twice, and felt much calmer.
In fact, if you think about it with normal thinking, someone from the criminal police team must have rechecked the fingerprints. Otherwise, if nothing else, Yan Ge and Wang Zhong, the two fingerprint examiners, must have been very busy and would have no time to follow. Play the guessing game on your own.
However, speculation was speculation. Jiang Yuan immediately opened the drawer, took out the horseshoe mirror, pressed the fingerprint card, and started reading.
With just one glance, Jiang Yuan was sure that he had won the competition.
He had been looking at the original fingerprints for too long, and the fingerprints he had just done had already been imprinted in his mind.
Despite this, Jiang Yuan turned on the computer again, called up the fingerprints of "Liu Yu Injury Case", and scanned it again.
This time, he mainly looked at whether there were any exclusions.
Is it possible for two identical fingerprints to appear in the world? In theory, based purely on theory, there should be. Because this is a question of probability. If the number is large enough, there is a probability that a monkey can write a Shakespeare by pressing the keyboard randomly.
However, if one of the characteristic points in the two fingerprints is different, then, both from a theoretical and practical point of view, the two fingerprints can be excluded from identification.
Jiang Yuan carefully identified them from beginning to end, and found nothing that could be excluded. Then he casually checked out 13 characteristic points, breathed a sigh of relief, and said with a smile: "There is no problem in the re-examination. It should be possible to determine that they are the same."
Yan Ge, who originally wanted to watch the fun, took a deep breath when he saw Jiang Yuan's last move.
He had already done the exact same job at short notice last night - as to why he was called out of bed for a re-examination and not Jiang Yuan, it was naturally because he was a senior trace inspection and the most qualified. Issue a fingerprint identification certificate. It was definitely not Comrade Huang Qiangmin, the captain of the Criminal Police Brigade, who had any private messages and was worried about wasting precious combat power of the police force.
However, just because he had done it yesterday, Yan Ge looked at Jiang Yuan's last move and became more and more suspicious of life.
Although he had some late-night IQ problems yesterday, it took about ten minutes to do a fingerprint identification, which can be said to be very reasonable.
But how long did it take Jiang Yuan to mark the feature points just now?
Yan Ge inadvertently recalled the horror of being dominated by all kinds of people when he was studying.
After a long time, Yan Ge let out a breath and said: "This case has been unsolved for 20 years, and I asked you to solve it just by sitting in an office..."
"We all work in the office." Forensic Doctor Wu corrected: "We all solve cases."
Yan Ge said: "Jiang Yuan today... should be regarded as the case he solved yesterday. It is enough to brag about for a lifetime. The serious injuries, the backlog of cases, and the name... I guess there must be many people in the bureau who still remember this case. . Especially the native-born leaders of our bureau, almost all of them were mobilized that year..."
"I just found a clue. Most of the work was done by other people in the team." Jiang Yuan made full use of the false modesty skills learned in school.
Lao Yan chuckled and said casually: "Without the clues you are looking for, there is no work for others to complete. Well, they are all off work, and I was asked to go back to work overtime, and there is no overtime pay."
Jiang Yuan fell into silence, not knowing whether to be humble or pass the blame at this time.
"Bang bang!"
Liu Wenkai, the captain of the second squadron, put his head in the door and said with a smile: "Jiang Yuan is here. You worked hard yesterday."
"I don't have anything hard to do..." Jiang Yuan ate skewers and drank beer last night, but he really didn't feel hard at all.
Liu Wenkai's face was red, full of excitement after staying up late, and he said: "If you hadn't matched the fingerprints, this case would probably be dead. You are said to be the first in the storytelling!"
Jiang Yuan changed the subject: "What about the suspect? I mean, what kind of person is he?"
Jiang Yuan only confirmed the suspect's identity by comparing his fingerprints, but didn't know anything else. As a young man who had just joined the job, Jiang Yuan was still somewhat curious about criminal suspects and the like.
Liu Wenkai thought for a while and then said: "He is just an ordinary person. He is also unlucky. He had a pen pal in our county back then. After the college entrance examination was over, he ran over to see the pen pal as soon as possible. As a result, when he arrived at the agreed time and place, he was not there. After meeting my pen pal and waiting for a day, my mood became very bad. I happened to meet the victim who was half-drunk, and a few words led to a conflict. If the attack was serious, it would lead to negative consequences."
"Where's the pen pal?"
"After this incident, he also knew that he had beaten people severely and never contacted his pen pal again." Liu Wenkai paused and then said: "His pen pal never wrote a letter again. But in his heart, he probably knew the reason. It comes down to my not showing up."
"So, except for the criminal suspect himself, no one knows that he has been to Ningtai County." Wu Jun concluded, and then sighed heavily: "He is unlucky, but he is also lucky."
"Ordinary people can't bear this kind of luck." Liu Wenkai said calmly: "When the person was stuffed into the car, he cried and collapsed, saying that he didn't dare to fall in love, get married, take out a loan to buy a house, and have to save money for his parents. Money, and to avoid appearing on any social media...Ask us why we didn't come earlier..."
Yan Ge couldn't help sighing when he heard this: "When the case happened, this person only took the college entrance examination, and now he is about 40 years old. It has delayed everything."
Liu Wenkai pouted and said, "I just asked him a question and helped him stop crying."
Yan Ge asked cooperatively: "What are you talking about?"
Liu Wenkai said: "I asked him why he didn't surrender earlier."
