Chapter 207 Change
The direction of criminal investigation is an extremely important power.

Even if the cadres of the provincial department came to Longli County, in theory, they only had the right to make suggestions, and could not just take over the criminal police team.Unless the county agrees.

In many cases, for many reasons, the direction of criminal investigation cannot be decided arbitrarily.

For criminal cases in Longli County, the first person responsible will always be Hou Lejia, who is the team leader.There are many situations that he has to consider, and after making a decision, it is all his responsibility.

Jiang Yuan expressed all his opinions, and went to the door to eat snail noodles.

Compared with instant noodles, snail noodles are good, that is, they can be stored for a little longer and soaked for a while, and the rice noodles are still in an acceptable state.It is even more delicious because it has been soaked for a while.

Jiang Yuan snorted as he ate, if it wasn't for the layer of oil floating on the noodles, which would have scalded his mouth slightly, he would have dried it all up in one breath.

Hou Xiaoyong also came out. Seeing how delicious Jiang Yuan's food was, he felt an inexplicable sense of accomplishment, and said, "The snail noodles I cooked are still good."

Jiang Yuan pondered for a while, took a smack, nodded, and said, "It's pretty good, professional level."

Hou Xiaoyong's snail powder skills are at LV1 level, which is much better than his field survey.

Hou Xiaoyong laughed twice, squatting next to Jiang Yuan and introduced: "Snail noodles are easy to cook, just control the order well, like this oil, it's boring to cook for a long time, and the peanuts should be put in later, otherwise It's not crispy anymore..."

Jiang Yuan nodded, it was a serious bowl of snail noodles.

"Brother Jiang, shall we wipe the scene later?" Hou Xiaoyong asked closely.

Jiang Yuan glanced at him and said, "I'll just wipe it myself."

Wipe the scene again to verify Jiang Yuan's own thinking, and on the other side, to see if there are any other more clues.

Similar to many scenes he had brushed before, the probability of finding any clues in this kind of scene that had already been dealt with once was very low.

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

In view of this, Jiang Yuan does not expect others to help.

Moreover, even if he asked someone for help, Jiang Yuan would rather ask Heizi for help than Hou Xiaoyong.

Hou Xiaoyong's face was full of disappointment, he lingered at the door, unwilling to go in, turned his head and said in a low voice: "Brother Jiang, I actually want to learn something from you, to steal from you..."

"You can't learn anything from me. You think too much." Jiang Yuan interrupted Hou Xiaoyong cruelly.

"You don't need to teach me, I'll just stand by and have a look."

"It's okay to look at, but it's not necessary." Jiang Yuan breathed a sigh of relief: "The survey is a meticulous job, and there are no martial arts cheats. Moreover, I guess it will be difficult to find any more evidence at the scene today."

Hou Xiaoyong showed disappointment.

He really wanted to find a kind of martial arts secret book.Martial arts cheats from on-site investigation.

However, from Jiang Yuan's point of view, it's not that LV0.6 players have no chance to practice, so there is no need to forcefully learn.

Even if Jiang Yuan doesn't open the game, after a few months of practice, he can approach the level of a professional player, that is, start at LV0.9. This kind of 0.6 is definitely a reverse talent.

The requirements for crime scene investigation are actually not high. It is basic to have a clear eye, a careful mind, and patience. It would be better if you have a little thinking and a little associative ability.

But Hou Xiaoyong seemed to have nothing to do with it.

It doesn't matter, he is still a good boy for his mother, a good baby for society, he is just not suitable for crime scene investigation.

It may be more reliable for Hou Xiaoyong to recognize the reality early and change positions.

"By the way, forensic doctor Ye is here, who is doing the autopsy?" Jiang Yuan asked again after finishing eating the snail noodles.

"Forensic doctor Wang Lan." Hou Xiaoyong said.

Jiang Yuan said inwardly that it was true.

Wang Lan went to at least half of the murder cases in Qinghe City, but Wang Lan went almost every time to the murder cases in Longli County.

There may be clues on the corpse, but when Wang Lan's forensic doctor found nothing, Jiang Yuan put the autopsy in second place.

After patting his stomach and urinating again, Jiang Yuan came back to change his clothes for on-site inspection, and drove most of the people out by the way.

Wang Zhong helped him, diligently dipped the brush, put on powder, and took pictures...

Cha Cha.

Kakaka.

Jiang Yuan was doing the on-site survey in a calm mood, and his movements gradually became soothing and rhythmic.

It's one thing whether you can do it or not, and it's over with elegance.

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

evening.

After the site survey was completed, some human hairs were found, and more were traces of rummaging at the site.

From this aspect alone, the element of burglary has been strengthened.

After all, if it is done by acquaintances such as the husband, there is no need to steal one's own property.Moreover, there is no need to go through so many places, and the time for committing the crime will not be prolonged, making it easier to be discovered.

However, the possibility of deliberate confusion by acquaintances cannot be ruled out.Or, maybe the alien hired by the husband is trying to make some extra money, or maybe rummage around.

After properly delivering the evidence to the evidence room in Longli County, Jiang Yuan went to their imaging office.

There are many ways to find burglars, but monitoring is the most reliable.

Mobile phone positioning is also possible. Now it is very convenient to locate through the base station, but this method usually only proves that someone is in a certain place. It is good for investigation, but it is not enough for evidence.

The police are too lazy to use this method for general burglary.If you don’t want to talk to Mr. Technical Detective, you have to look for 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 looking for fingerprints, or looking for DNA evidence such as hair and sweat is also a better solution.It is to test the ability of the current survey. On the other hand, the thief who has been caught once in this way will often grow after he comes out of the prison university.

Such evidence can often be perfectly circumvented by wearing gloves, coveralls and the like.However, the possibility of leaving sweat still exists. The thicker the clothing, the greater the possibility of sweating when committing crimes. It depends on whether the current survey can find it.

In a normal criminal investigation environment, the police system's investment in burglary is average. In fact, it prefers the model of pulling carrots and mud, which is to wait.

Otherwise, there are more cases of looking for stolen goods.

In contrast, looking for suspects through monitoring is a very labor-saving positive case-solving mode.

Hou Lejia looked a little excited, saw Jiang Yuan, and whispered: "Recently, there have been a series of burglaries. Moreover, most of the cases involved the theft of bicycles and electric vehicles, which should be done by the same person. .”

"After stealing bicycles and electric vehicles, are they used to carry things?"

"Yes, when he steals, he usually finds the key, installs some large items such as a computer, and brings a bicycle or electric car. If he can't find the key, he should also unlock the lock."

Ordinary recidivists have almost fixed patterns of crime.

This is like ordinary people going to work. After going to work for a long time, what time to get up in the morning, which route to take, and which car to take, all have a fixed pattern in the end.

A criminal's work is equivalent to going to work. Even if he wants to escape the blow, he can't just think about changing.

Not so innovative.

If he could come up with new ideas at every turn, he would have been a capitalist long ago, and he would have no time to engage in burglary.

A successful criminal will often strengthen his criminal pattern, because he has tried and tested repeatedly, and will definitely feel that his criminal pattern is advanced.

Similarly, you can also refer to small Japanese movies. In the same series, the action rhythm is not changed, and the heroine is changed.

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

Committing crimes many times, the probability of completely evading monitoring is very low.

Moreover, criminals who burglary did not need to be on guard to such an extent.It's not like every time someone dies.

Hou Lejia nodded, asked his subordinates to watch it, and said: "I'm still watching other videos, there should be more later."

While speaking, a black shadow appeared on the screen.

The picture is a bit dirty, you can see the action, but you can't see the face.

"Can you identify the suspect?" Jiang Yuan asked again.

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

As long as the surveillance captures it, there are still many ways to continue to find someone.

Jiang Yuan looked at the time, it was already 10 o'clock in the evening, if you delay, it will definitely be all night today.

Jiang Yuan simply said: "Find me a computer, I'll adjust the picture."

　Recently chewing ginseng code words, the effect is quite good.Gradually, I was able to feel a hint of sweetness from chewing ginseng... Today I found that I ate half a can of ginseng, and I felt that I had eaten too much, so I took a piece under my tongue at night, and the effect seemed to be good...
