Chapter 11: Intentional Injury Case

"Little Wang also likes to tinker with computer software. In the past, when coordination cases came to our county, Little Wang arranged them." Old Yan endorsed Little Wang, and by the way, rectified the name for the only two trace examinations in the county.

Wang Zhong smiled shyly and said modestly: "I can't compare with what Wu Wu Fa Yi Jiang did. You are the one who does fingerprints with hard bridges and hard horses. I mainly run the fingerprint database."

The fingerprint database is constantly updated, and the main body responsible for the update is the trace examination police in various places. They are responsible for taking photos, archiving, filling in instructions, and sometimes need to perform manual processing, and then put them into the fingerprint database. In addition, the fingerprints of old cases before the computer system was adopted also need manual verification and other operations before they can be put into the database.

Occasionally taking out the fingerprints of old cases to run is a kind of running database. The suspects that could not be matched before, maybe one day they got drunk driving or fighting, and they were matched. Even if the criminal suspect handled a temporary residence permit, it might make the lonely fingerprints get paired, which can be described as adult beauty.

In addition, some people committed crimes in other places, and could not find a match in the local fingerprint database, but it is possible that they left fingerprint information in the fingerprint database of other places. This kind of fingerprint is not necessarily complicated. Many times, the trace examination police who received the coordination letter, roughly marked the feature points in the most traditional mode, and then ran the fingerprint database, and hit two poles with or without dates, which might also be matched.

Running the database is also the daily life of most ordinary trace examination police. If Jiang Yuan didn't have a system, it would be good to be able to run the database in the first few years. Therefore, he was gentle and sincere: "No matter if it is a white cat or a black cat, catching a mouse is a good cat."

Wang Zhong felt that Jiang Yuan, a young man, was not bad and could be dealt with, so he was even more modest and made a metaphor: "In terms of catching mice, you are a civet cat, and I am at most a ragdoll cat."

Everyone present looked at Wang Zhong's cheeks, which were rough due to frequent scenes and staying up late, and then looked at Jiang Yuan, who was white and gentle, and fell into a tactful contemplation.

"You just said there is a case?" Wu Jun reminded.

"Right, right, right." Wang Zhong sorted out the language and said: "It's an old case more than ten years ago. I had a deep impression when I ran the database before. The case is simple to say. It was a few high school graduates who drank farewell wine, got drunk, had a conflict with a young man passing by, and were turned over by someone picking up a stool. The unlucky thing was that the student who was beaten was blinded in one eye, which became causing serious injury."

"You said one eye was blinded, and I remembered it. At that time, the college entrance examination was still in July, and the weather was hot. There were students making trouble after drinking beer everywhere. The university admission rate was low that year, and students who had nowhere to go, as well as repeaters, were looking for trouble everywhere. The most serious one was this case. The student who was beaten was still an excellent student and was admitted to a junior college. I guess the beating was also for this reason." Wu Wu Fa Yi Wu recalled the past with great emotion: "It was my master who did the judicial appraisal."

"It's this case. At that time, it was guessed that the suspect might be a student from other places who came to play, or it might be a migrant worker who ran away after the incident." Little Wang nodded.

It was a bit far for Yan Ge more than ten years ago, and he hadn't read the file, so he asked directly: "Didn't you set up a special case team?"

"The county set up a special case team, but it was mainly visiting and investigating, and finally did not lock the suspect."

"What about the city?"

"Didn't enter the city."

"There was no sinking at that time, and the Qinghe City Bureau basically didn't do business." Wu Jun explained. In the early years, the provincial department and the city bureau were business guidance, not direct business. To put it simply, they don't handle cases directly.

For example, the provincial department has a total of only a few hundred people, and it is a major case, but it can't handle it, and even daily work needs to borrow people from the districts and counties below, so it is better to put the case in the districts and counties and do some technical and organizational work by themselves.

The tension of the city bureau's manpower is slightly better. In recent years, they have also been required to sink and handle cases directly, etc., but for backward areas like Qinghe City and Shan'nan Province, requirements are requirements, and reality is reality.

Therefore, not only could the intentional injury case more than ten years ago not reach the city bureau, but even now, serious injury cases must have a huge impact before a city-level special case team will be organized. Of course, if it is changed to a homicide case, that is another matter.

"There is also a problem with fingerprint clues." Little Wang continued to introduce: "At that time, fingerprints were extracted from the stool leg used by the suspect as a murder weapon, but the stool leg was made of round steel pipes..."

"Oh..." Yan Ge and Jiang Yuan showed a look of sudden realization. The photography and extraction of cylindrical traces has always been a major problem in criminal investigation scene survey. The curved shape makes the fingerprint deformation serious, and the curved surface makes the reflection serious when taking photos... Although fingerprints can still be taken, the integrity and accuracy of fingerprints will be greatly reduced.

"When taking fingerprints back then, it must have been fixed by the segmented shooting method, and the deformation must be quite large..." Yan Ge guessed, and sighed: "We went to train for the auxiliary cylindrical surface unfolding shooting method at that time, which is a special machine, shooting while turning, and finally only the provincial capital bought it. If you want to use it, you have to hit a few applications. Now it's better. Mobile phone open, a panoramic shooting, better than that one!"

Jiang Yuan laughed dumbly, and opened the software on the computer, and found the case.

The four fingerprints left by the suspect soon appeared on the screen, and everyone stretched their heads to look.

After only a few seconds, Yan Ge and Wang Zhong gave up hope.

The clarity of the image is okay, but there are many breakpoints. Needless to say, the judgment must be difficult. The main thing is that there is obvious extension on the left and right sides of the fingerprint, and the texture lines of the deformed part are obviously widened and thickened. In this way, the image must be deformed first, and then the fingerprint must be marked. In terms of difficulty, it is definitely a high-level requirement.

According to Yan Ge's judgment, let alone him and Little Wang, even if it is sent to the city or even the province, whether it can produce results is hard to say.

Wang Zhong has been paying attention to this case since he ran the database, and said excitedly: "The advantage of this case is that the fingerprints on the murder weapon, except for these few continuous fingerprints, have been excluded. In addition, at that time, a portrait artist was invited to draw a portrait of the suspect. Although so many years have passed, there are fingerprints and portraits, so it should be relatively easy to confirm."

Everyone present nodded. This is indeed an advantage. The number of cold cases that can be solved through fingerprints is limited, and it is even more difficult to convict directly. Plus there are portraits, and there are parties and eyewitnesses. If the fingerprints are matched, you can directly catch people and close the case.

Of course, the premise of everything is to be able to match the fingerprints.

Everyone, including Wu Jun, looked at Jiang Yuan.

Jiang Yuan couldn't help but smile.

"It seems that Jiang Yuan is sure." Little Wang suddenly envied Jiang Yuan a little.

"I'll try it." The main reason Jiang Yuan smiled was that the fingerprints left by the suspect happened to be arch patterns. If not, he would have to push this case away.

As for the difficulty, judging from his experience in doing fingerprints in the past two days, it seems to be within the range. It's just that it's unlikely to be achieved in one go.

Wu Jun laughed at this time and said: "Solving the case is solving the case, and rest is rest. Don't be in a hurry today. Anyway, it's already a cold case, and it's not a day or two..."

He deliberately interrupted. In any case, Yan Ge and Wang Peng are professional trace examination police in the team, and Jiang Yuan is a forensic doctor, and also his apprentice. It is not a thing to let two trace examinations watch Jiang Yuan, a young man, do fingerprints.

"Indeed, you must have been exhausted from handling corpses these two days. Take it easy." Yan Ge also laughed, pulled Wang Zhong and left.

Wu Jun and others went out, picked up the teacup and drank water, and said to Jiang Yuan: "Don't be in a hurry, it's almost time for lunch break. You should tidy up, eat, and see if you want to fry rice again today?"

Jiang Yuan was not in a hurry, and asked: "Can the cafeteria in the team fry rice by itself?"

Wu Jun waved his hand: "No need to find them, the police dog squadron also has a kitchen."

Jiang Yuan:.?????.
