Chapter 325

"a53 and b167."

"a33, a34 and b13."

"Put the sticks aside separately, don't mess up the numbering, I'll look at them once."

"a11 and b208, each do a trace evidence inspection."

Jiang Yuan checked the photo groups with ease, and the evidence that filled the long conference table was constantly being photographed, numbered, and recorded.

In most cases, Jiang Yuan didn't need to open the packaging of the evidence, or he would seal the evidence in advance before looking at it. In this way, after the tool mark identification was determined to be the same, he could use the trace evidence method for verification.

The cost of trace evidence is not low. Even in his own laboratory, doing it once costs hundreds of yuan. If the quantity is slightly larger, it is easy to make the money for an Audi. This is without counting the costs of laboratory construction and maintenance.

If one wants to calculate the cost of the latter, one can use the Judicial Appraisal Institute as a standard. Their price for doing trace evidence externally is around 1000 yuan, similar to the price of paternity testing—for reference by those in need.

It can be understood without too much explanation. Places like the Ningtai County Criminal Investigation Detachment, which treats a second-hand Great Wall Cannon as a treasure, are reluctant to use trace evidence unless it is a major murder case.

The Changyang Municipal Criminal Investigation Detachment is actually about the same. The value of theft cases starts from 3000 yuan, and more than 100,000 is considered a lot. If one wants to use trace evidence to solve the case, the cost-effectiveness is completely out of the question; it is purely out of social value and cracking down on crime.

This time is also the same. Several cases Jiang Yuan found were all small cases with low value, some prying cars to steal things, some opening warehouses to steal, some passing trucks losing things, and some stealing oil from large trucks...

In summary, this parking lot security team of Jianyuan Pharmaceutical had long been dissatisfied with the income of the parking lot and began to actively pursue "income diversification."

"With so many small cases, maybe some people haven't even reported them. We should be able to catch half of the people here." Tang Jia helped Jiang Yuan organize on the side, slowly being stirred up, and soon became excited.

"The steps for doing small cases are the same." The prosecutor invited to intervene in advance was a quota prosecutor, and also brought a small group.

The so-called quota prosecutor is a prosecutor with full authority to handle cases. Or rather, only quota prosecutors can lead the handling of cases, other prosecutors can only appear as auxiliary case-handling personnel, and non-prosecutors are called judicial administrative personnel.

Because quota prosecutors are proportional and often have insufficient quotas, quota prosecutors have become scarce goods since the beginning of the system. Yu Wenshu being able to call a quota prosecutor over this time was a great support for the case.

If the people involved in this case understood the principles, the best thing to do would be to obediently plead guilty.

Jiang Yuan now does more cases and understands the principles. To show respect, he said seriously to the quota prosecutor next to him: "Prosecutor Liu, these pieces of evidence are directly matched to the cases. There will be relatively large cases later. Well, for example, a80, 83, b263 and b288... This should be a case of serious injury."

The small trace examiner hurriedly went to get the things, spread them out, and saw that it was actually a striking mark on the surface of an axe, and the photo in his right hand was exactly an axe.

"The same thing?" Prosecutor Liu was a bit happy.

"It can be determined to be the same, the same thing, but other evidence still needs to be fixed." Jiang Yuan said.

"Not bad, not bad, this case is worth a trip." Prosecutor Liu nodded repeatedly.

In most cases, three criminal police officers doing a small case still have to spend several days. Because no matter how small the case is, the process is actually about the same. To form a complete chain of evidence, it takes a lot of time.

Quota prosecutors are the same. The steps for doing small cases are not few, and the sense of achievement is low.

However, quota prosecutors have greater power. When doing small cases, they often give criminals who plead guilty and accept punishment a suspended sentence, or reduce the punishment to reduce the workload.

In the end, prosecutors, like police, all like to strike hard at criminals

instead of scraping the criminals.

Prosecutor Liu called out the old case files, looked at them for a while, and said to Jiang Yuan: "The previous forensic identification was serious injury second-degree, the victim's disability level is not enough, so calculated, the criminal should be sentenced to three to five years, a little bit short of meaning..."

Jiang Yuan silently handed him a few other photos.

Prosecutor Liu was like getting a cheat sheet in an exam, and couldn't help but say with surprise: "There's more? The same person, or another one?"

"The same criminal, this time using an iron rod. It has edges. It should be at the level of minor injury first-degree. In addition, rape." Jiang Yuan pointed to the surface of the iron rod and said: "He knocked the person down with one rod, and then committed rape. This person is the most brutal among this group."

Prosecutor Liu's eyebrows stood up as he listened, and he couldn't help but say: "I didn't expect there to be such a big case in this."

Jiang Yuan said "Well", and said: "He likes to hang around the national highway, so not only within the jurisdiction of Changyang City, but also in the nearby counties, he has left his footprints. I have people looking for him."

"Serial rape?" Prosecutor Liu was somewhat incredulous. Although he had done many vicious cases, if it were really this vicious, it was still too unexpected.

Jiang Yuan said somewhat uncertainly: "Judging from the proficiency of the cases he committed, it shouldn't be the first time. However, the coverage of the previously prepared cases is not enough. I plan to flip forward to see if there are similar ones in the previous cold cases."

"Good, good, good." Prosecutor Liu nodded repeatedly, then lowered his head and looked at the case file for a moment, saying: "You find two more serious injuries or one rape case, and I have the confidence to nail him to life imprisonment."

"I'll find three for you, striving for the death penalty." Jiang Yuan answered casually. He had done many cold murder cases, and the goals he pursued were naturally more ambitious.

Prosecutor Liu was stunned when he heard this, and then looking at Jiang Yuan's very natural expression and actions, he couldn't help but sigh: "Sure enough, only the name can be wrong, there is no wrong nickname."

"What?" Jiang Yuan didn't hear clearly.

"Nothing, you go ahead." Prosecutor Liu was also a person in his 40s, but after spending a while with Jiang Yuan, he couldn't help but feel waves of warm, chilly wind.

For a whole day, Jiang Yuan chased the marks of a security guard and kept investigating.

Criminals are not made in a day. Guys like this who can skillfully complete robbery, rape, and injury to others must have participated in many fights. Things like causing minor injuries will happen if one is not careful.

It's just that some people always escaped punishment through some means.

This time, Jiang Yuan caught his tail and touched it all the way up.

In modern society, it is very difficult to practice exquisite criminal skills. Most criminals can only improve through a single upgrade route. In other words, their crimes often have patterns.

There may be more powerful criminals who have two or three criminal patterns, but whether it is one or two or three, for criminal investigation personnel, it can only be said to be okay.

Just like most criminals, this parking lot security guard could escape punishment mainly by luck.

Now, his luck is considered used up.

Striking marks, scratching marks, stabbing marks, cutting marks...

Those who like to use weapons may gain an advantage during the commission of the crime, but during the case-solving stage, they will also give obvious signals.

It is still a question of variety. Just the variety of knives is so many, and those who are good at and like to use weapons actually only use a few common ones.

When doing cold cases before, Jiang Yuan did cold murder cases and couldn't take care of ordinary major cases. Now, crawling up along the tool marks, he is grabbing both minor and serious injuries.

Evening.

Shen Yaoguo sent the Sichuan cuisine that everyone loves, the spicy kind.

"Let's eat first. It's too simple. Actually, going to the cafeteria to eat doesn't take much time..." Yu Wenshu didn't go back either. Today's scene was not only big but also interesting, plus there was a prosecutor specially invited, so he accompanied them.

Prosecutor Liu waved his hand indifferently and said: "It's already very good. Sometimes we eat instant noodles when we stay up late

. Today it's my hometown food."

"As long as Prosecutor Liu doesn't mind." Yu Wenshu talked to the few young people next to him, taking care of everyone as much as possible.

When working, one must be serious; when eating, one must be gentle.

Jiang Yuan pushed the organized case file to Prosecutor Liu and began to eat with peace of mind.

Prosecutor Liu naturally took it and read it. He wasn't familiar with other police officers either. The police officers of Jiang Yuan's cold case task force were almost all young people, and they rarely did major cases in the past, so it wasn't their turn to deal with him.

Everyone ate and rested, which was quite relaxed.

Shen Yaoguo, on the other hand, had a full social butterfly attribute, could chat with everyone, walked around, and came back. Seeing that Prosecutor Liu already had sweat on his forehead, Shen Yaoguo smiled and said: "Prosecutor Liu, if it's too spicy, you can eat it with bean curd."

Prosecutor Liu: "It's not spicy; I'm from western Sichuan."

Shen Yaoguo smiled: "Your sweat is flowing down."

Prosecutor Liu wiped his forehead, and sure enough, there was a lot of sweat. He couldn't help but shake his head and said: "I'm not eating spicy food; I'm looking at the case file."

"Why?"

"Looking at it now, I can already request the death penalty." Prosecutor Liu said without a beginning or end, but everyone understood.

Everyone couldn't help but look at Jiang Yuan.

Jiang Yuan scooped a bowl of bean curd and said calmly: "It's not that I found enough cases; it's that he committed enough cases. You'll know after reading the case file; the death penalty is deserved."

Everyone looked at Prosecutor Liu again.

Prosecutor Liu gave a deep "Well".

Jiang Yuan added: "In this case, we should be able to find a breakthrough from this guy."

"That's for sure. He committed so many cases; it's impossible for him to have done them all alone." Prosecutor Liu guessed while looking at the content of the case file: "If the accomplices in several major cases here are all the same person or two people, we can sentence another death penalty."

"That's good." Jiang Yuan picked up several pieces of boiled meat to go with rice, revealing a satisfied smile.

Others present were eating the same spicy Sichuan food, and brain flowers couldn't help but emerge in their minds: Ningtai Jiang Yuan's fierce flames are billowing...
