Chapter 207: Change

The criminal investigation direction is an extremely important power.

Even if cadres from the provincial department arrived in Longli County, theoretically, they would only have the right to suggest, and could not take over the criminal police team. Unless the county agreed.

Many times, for many reasons, the criminal investigation direction cannot be decided at will.

The first person responsible for criminal cases in Longli County will always be Hou Lejia, the captain. He has to consider many situations, and after making a decision, he has to be responsible for everything.

Jiang Yuan expressed all his opinions and went to the door to eat Luosifen.

Compared to instant noodles, Luosifen has one good point: it can be left for a while, and if soaked for a while, the state of the rice noodles is still acceptable. Even because it has been soaked for a period of time, it is even more flavorful.

Jiang Yuan ate it with a slurping sound; if it weren't for the layer of oil floating on top of the noodles, which was a bit hot, he could have finished it in one breath.

Hou Xiaoyong also came out, and seeing Jiang Yuan eating so deliciously, he inexplicably felt a sense of accomplishment and said: "The Luosifen I cooked is still okay, right?"

Jiang Yuan pondered, savored it, nodded, and said: "Quite good, professional level."

Hou Xiaoyong's Luosifen skill was at LV1 level, which was more powerful than his crime scene investigation, much more powerful.

Hou Xiaoyong laughed twice and squatted next to Jiang Yuan to introduce: "Luosifen is simple to cook, but you have to control the order. Like this oil, it's boring if cooked for too long, and peanuts should be put in later, otherwise they won't be crispy..."

Jiang Yuan nodded; it was a very serious bowl of Luosifen.

"Brother Jiang, are we going to scrub the scene in a while?" Hou Xiaoyong leaned in and asked.

Jiang Yuan glanced at him and said: "I'll just scrub it myself."

Scrubbing the scene again was also to verify Jiang Yuan's own ideas, and on the other hand, to see if there were any other more clues.

Similar to many scenes he had scrubbed before, the probability of finding clues in a scene that had already been processed once was very low, and if found, they were usually just clues.

What's more, the scene had been broken into by onlookers in the early stages of the incident, and the value of the evidence was greatly reduced.

In view of this, Jiang Yuan didn't count on others to help.

And even if he asked for help, Jiang Yuan would rather ask Blackie to help than Hou Xiaoyong.

Hou Xiaoyong's face was full of disappointment, rubbing at the door, unwilling to go in, and turned back to whisper: "Brother Jiang, I actually want to learn something from you, steal a teacher, steal a teacher..."

"You can't learn anything from me. You're overthinking it." Jiang Yuan cruelly interrupted Hou Xiaoyong's words.

"I don't need you to teach me, I'll just stand by and watch."

"Watching is fine, but it's not necessary." Jiang Yuan took a breath: "Doing crime scene investigation is a meticulous job, and there are no martial arts secrets. Moreover, for today's scene, I estimate it will be very difficult to find any evidence again."

Hou Xiaoyong looked disappointed.

He really wanted to find a martial arts secret. A martial arts secret for crime scene investigation.

However, as far as Jiang Yuan was concerned, an LV0.6 player wasn't without a chance to practice, so there was no need to force learning.

Even without Jiang Yuan's cheating, practicing for a few months would bring one close to the level of a professional player, which was starting at LV0.9. A 0.6 one was definitely opening a reverse talent.

The requirements for crime scene investigation are actually not high; being sharp-eyed, meticulous, and patient is basic, and having some ideas and association ability is even better.

But Hou Xiaoyong didn't seem to have any of that.

This didn't matter; he was still his mother's good child, society's good baby; he just wasn't suitable for crime scene investigation.

Recognizing reality early and changing positions might be more reliable for Hou Xiaoyong.

"By the way, Wu Wu Fa Yi Ye is here, who is doing the autopsy?" Jiang Yuan asked after finishing the Luosifen.

"Wu Wu Fa Yi Wang Lan." Hou Xiaoyong said.

Jiang Yuan secretly said "as expected".

For newly occurred homicide cases within Qinghe City, Wang Lan went to at least half, but for newly occurred homicide cases in Longli County, Wang Lan almost came every time.

There might be clues on the corpse, but since Wu Wu Fa Yi Wang Lan had no findings, the autopsy was placed in the second priority by Jiang Yuan.

Patting his belly and going to take a pee, Jiang Yuan came back to change clothes and do the crime scene investigation, and by the way, drove most people out.

Wang Zhong helped him, diligently dipping the brush, applying powder, taking photos...

Chacha.

Kaka kaka.

Jiang Yuan did the crime scene investigation with a calm mood, his movements gradually becoming relaxed and rhythmic.

Whether it could be done or not was one thing, being elegant was enough.

Hou Xiaoyong watched at the door for a while, didn't understand, wanted to wait for Jiang Yuan to look over, but couldn't hold his temper, so he withdrew.

Evening.

The crime scene investigation was completed, and some human hair was found, and more were traces of searching at the scene.

Judging from this aspect alone, the component of burglary was strengthened.

After all, if it were done by acquaintances like the husband, there would be no need to steal one's own property. And there would be no need to search so many places, which would only prolong the crime time and make it easier to be discovered.

However, the possibility of acquaintances deliberately confusing the public could not be ruled out. Or, the alien hired by the husband might want to earn an extra income, and might also search everywhere.

Handing the evidence properly to the Longli County evidence room, Jiang Yuan went to their imaging office.

There are many ways to find thieves who commit burglary, but surveillance is the most reliable.

Mobile phone positioning is actually okay; now, positioning through base stations is already very convenient, but this trick can usually only prove that someone is in a certain place, which is good for investigation, but not enough for evidence.

For ordinary burglary, the police are too lazy to use this method. Not to mention finding the technical investigation uncle, they have to find evidence again later, which is equivalent to licking both ends of a bitter melon, using the wrong place and choosing the wrong function.

Of course, the more traditional way of finding fingerprints, or finding DNA evidence such as hair and sweat, is also a better plan. It just tests the ability of crime scene investigators; on the other hand, small thieves who have been caught once in this way, after coming out of prison university, will often grow.

By wearing gloves, wearing jumpsuits, etc., they can often perfectly avoid such evidence. However, the possibility of leaving sweat still exists; the thicker they wear, the greater the possibility of sweating during the crime, it just depends on whether the crime scene investigator can find it.

And in a normal criminal investigation environment, the police system's investment in burglary is mediocre; in fact, they prefer the mode of pulling out the radish and bringing out the mud, which is sitting and waiting.

Otherwise, there are many cases of finding them back through stolen goods.

In contrast, finding suspects through surveillance is a very labor-saving positive case-solving mode.

Hou Lejia looked a bit excited, and seeing Jiang Yuan, whispered: "Recently, there has indeed been a series of burglaries. And, most of the cases have stolen bicycles and electric vehicles; it should be the same person."

"After stealing bicycles and electric vehicles, use them to carry things?"

"Yes, he usually finds the key while stealing, and then loads more large items like computers, and takes them away with the bicycle or electric vehicle. If he can't find the key, he should also be able to pick the lock."

Ordinary recidivists have almost fixed criminal patterns.

This is like ordinary people going to work; after a long time, what time to get up in the morning, which route to take, which bus to take, in the end, are all fixed patterns.

Criminals working is equivalent to going to work; even if they want to escape the crackdown, they can't think of changing at every turn.

They don't have such strong innovative ability.

If they could think of new ideas at every turn, they would have become capitalists long ago; where would they have time to commit burglary.

A successful criminal will often strengthen his criminal pattern, because it works every time, and he will definitely feel that his criminal pattern has its advanced nature.

Similar references can be made to Japanese small movies; the same series doesn't even change the rhythm of the action, just changes the heroine.

"Is there any surveillance video of the suspect?" Jiang Yuan asked directly.

The probability of completely avoiding surveillance after committing multiple crimes is very low.

Moreover, criminals who commit burglary don't need to be so defensive. It's not like people die every time.

Hou Lejia nodded, let his subordinates play it for him to see, and said: "Other videos are still being watched, there should be more later."

While speaking, a black shadow appeared on the screen.

The picture was a bit dirty, the movements could be seen, but the person's face couldn't be seen.

"Can you determine the suspect's identity?" Jiang Yuan asked again.

"Still trying to find a way." Hou Lejia was relatively confident.

As long as surveillance captured it, there were still many ways to find people.

Jiang Yuan looked at the time; it was already 10:00 PM. If he delayed any longer, he would definitely have to stay up all night today.

Jiang Yuan simply said: "Find a computer for me, I'll adjust the image." ===== CHAPTER 208 =====
