Chapter 11 Intentional Injury Cases

"Xiao Wang also likes to tinker with computer software. In the past, when our county came to assist in the investigation, it was arranged by Xiao Wang." Lao Yan made an endorsement for Xiao Wang, and also rectified the name of the only trace inspection in the county. .

But Wang Zhong smiled shyly, and said modestly: "My work is incomparable to that of Forensic Doctor Jiang. You are a hard-working fingerprint maker. I mainly just run to the fingerprint database."

The fingerprint database is constantly updated, and the main body responsible for the update is the trace inspection police from all over the country.They are responsible for taking pictures of the collected fingerprints, filing them, filling in instructions, and sometimes manual processing before putting them into the fingerprint library.In addition, using the fingerprints of old cases before the computer system also requires manual checks and other operations before they can be put into storage.

From time to time, I take out the fingerprints of the old cases and run around, which is a kind of running warehouse.Suspects who could not be matched before may be matched one day after a drunk driving or a fight.Even if the criminal suspect has applied for a temporary residence permit, the lonely fingerprints may be matched, which can be described as the beauty of adults.

In addition, some people commit crimes in other places and cannot find a match in the local fingerprint database, but they may have fingerprint information in the fingerprint database in other places. This kind of fingerprint is not necessarily complicated. After receiving the assisted investigation letter, use the most traditional mode to roughly mark the feature points, and then run the fingerprint database, and if there are dates or no dates, two shots may be hit.

Running the warehouse is also the daily routine of most ordinary trace inspection police. If Jiang Yuan does not have a system, it will be good to be able to run the warehouse in the first few years. Therefore, he said kindly and sincerely: "It doesn't matter if the cat is white or black, if you catch a mouse Just a good cat."

Wang Zhong immediately felt that Jiang Yuan was a good young man who could get along with him, so he made a more self-effacing analogy: "In terms of catching mice, you are a raccoon cat, and I am at best a puppet cat."

All the people present looked at Wang Zhong's rough skinned cheeks, which appeared all the year round and stayed up all night, and then looked at the fair and gentle Jiang Yuan, and fell into euphemistic contemplation.

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

"Yes, yes, yes." Wang Zhong sorted out his words before saying, "It's an old case more than ten years ago. When I ran out of the warehouse, I was quite impressed. The case is simple to say, it is a few high school graduates drinking wine , was drunk, had a conflict with a young man passing by, and was knocked over by someone picking up a stool. Unfortunately, the student who was beaten was blinded in one eye, which became a serious injury."

"You said you were blind in one eye, so I remember it. At that time, the college entrance examination was still in July. When the scores came down, the weather was hot, and there were students who drank beer and made trouble everywhere. The university admission rate was low back then. The students who went to other places, as well as the repeat students, were looking for faults everywhere. The most serious case was this case. The student who was beaten was still a top student and had passed the college entrance examination. I guess this is also the reason for the beating.” Forensic doctor Wu recalled the past with emotion: “It’s still Forensic appraisal done by my master."

"It's this case. At that time, it was speculated that the suspect might be a foreign student who came to play, or he might have come to work, and ran away after something happened." Xiao Wang nodded.

More than ten years ago, Yan Ge was a little far away, and he didn't read the files, so he asked directly: "Didn't you set up a task force?"

"The county set up a task force, but the main thing was to search and investigate, and the suspect was not identified in the end."

"It's in the city."

"Didn't enter the market."

"The Qinghe Municipal Bureau basically didn't do any business before the sinking took place." Wu Jun explained.In the early years, the provincial departments and municipal bureaus were doing business guidance instead of doing business directly.To put it more simply, they do not handle cases directly.

For example, the provincial department has a total staffing of only a few hundred people. Even major and important cases cannot be handled. Even daily work needs to be seconded to people from the districts and counties below. Work.

The manpower of the Municipal Bureau is slightly tighter, and it has been required to go down and handle cases directly in recent years, but for backward areas like Anping City and even Shannan Province, the requirements are the requirements, and the reality is the reality.

Therefore, not only did the intentional injury cases more than ten years ago fail to reach the city bureau, but even now, serious injury cases had to have a great impact before organizing a city-level task force.Of course, if it were a homicide case, that would be another matter.

"Fingerprint clues are also problematic." Xiao Wang went on to introduce, saying: "At that time, the fingerprints were extracted from the stool leg that the suspect used as the murder weapon, but the stool leg was made of round steel pipe..."

"Oh..." Yan Ge and Jiang Yuan both showed stunned expressions.The extraction of cylinder traces has always been a major problem in criminal investigation. The curved shape makes the fingerprints seriously deformed, and the curved surface makes the reflection serious when taking pictures...Although the fingerprints can still be obtained, the integrity of the fingerprints and the Accuracy will be greatly reduced.

"The fingerprints taken back then were probably fixed by segmented shooting method, and the deformation must have been quite large..." Yan Ge guessed, and then said with emotion: "At that time, we also went to train some auxiliary methods for shooting the surface of the cylinder, that is A special machine that shoots while turning around, only the provincial capital bought it in the end, and it takes a few applications to use it, but now it’s ready, the phone is turned on, and it can take a panoramic shot, which is even easier to use than that one!”

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

The four fingerprints left by the suspect soon appeared on the screen, and several people looked at it with their heads hooked.

In just a few seconds, both Yan Ge and Wang Zhong gave up hope.

The clarity of the image is acceptable, but there are many breakpoints. Needless to say, it must be difficult to judge.The most important thing is that there are obvious extensions on the left and right sides of the fingerprint, and the lines of the deformed part are obviously wider and thicker. In this way, the image must be deformed first, and then the fingerprint is marked. In terms of difficulty, it is absolutely It is an advanced requirement.

As far as Yan Ge judged, let alone him and Xiao Wang, it is hard to say whether it will produce results even if it is sent to the city or even the province.

Wang Zhong has been paying attention to this case since he ran out of the warehouse. At this time, he said with great interest: "The advantage of this case is that the fingerprints on the murder weapon, except for these few consecutive fingerprints, have been ruled out. In addition, at the beginning I hired a portrait artist to draw a portrait of the suspect, although it has been so many years, but there are fingerprints and portraits, so it should be relatively easy to confirm."

Everyone present couldn't help nodding.This is indeed an advantage. The number of accumulated cases that can be solved through fingerprints is limited, and it is even more difficult to directly convict.In addition, there are portraits, parties and witnesses. If the fingerprints are matched, the person can be arrested and the case closed.

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

Lao Yan and Xiao Wang, including Wu Jun, all looked at Jiang Yuan.

Jiang Yuan smiled unconsciously.

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

"I'll give it a try." The main reason for Jiang Yuan's smile was that the fingerprints left by the suspect happened to be bow-shaped. If it weren't for this, he would have to evade the case.

As for the difficulty, based on his two-day fingerprinting experience, it seems to be within range.It's just not likely to happen overnight.

Wu Jun laughed at this time, and said: "Solving the case belongs to solving the case, resting belongs to resting, don't worry about it today, it's all backlogged cases anyway, it's not bad for a day or two..."

He interrupted on purpose.Anyway, Yan Ge and Wang Peng are both professional trace inspection policemen in the team, while Jiang Yuan is a forensic doctor and his apprentice.It's not a big deal for two trace inspection policemen to watch Jiang Yuan, a young man, do fingerprints.

"Indeed, you guys are probably exhausted from handling corpses these two days, so take your time." Yan Ge also laughed, and pulled Wang Zhong away.

Wu Jun and the others went out, took a drink from the teacup, and said to Jiang Yuan: "Don't worry, it's time for lunch break soon, it's time to tidy up, it's time to eat, do you want to cook another meal today?"

Jiang Yuan was really not in a hurry, and asked, "Can the cafeteria in the team cook their own rice?"

Wu Jun waved his hand: "There's no need to look for them, the police dog squadron also has a kitchen."

Jiang Yuan: ..
