The direction of criminal investigation is a very important power.

Even if the cadres from the provincial department come to Longli County, theoretically, they only have the power to suggest and cannot take over the criminal investigation team. Unless the county agrees.

Many times, for many reasons, the direction of criminal investigation cannot be decided arbitrarily.

In Longli County, the person responsible for criminal cases is always the captain, Hou Lejia. He has to consider many situations, and once he makes a decision, he is fully responsible for it.

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

Compared to instant noodles, snail noodles have one advantage, which is that they can be left for a longer time and soaked for a while, and the condition of the rice noodles can still be accepted. Even because it has been soaked for a while, it tastes even better.

Jiang Yuan ate with gusto. If it weren't for the layer of oil floating on the noodles, which was slightly hot, he could finish it in one breath.

Hou Xiaoyong also came out and saw Jiang Yuan enjoying the food so much that he inexplicably felt a sense of accomplishment and said, "The snail noodles I cooked are pretty good."

Jiang Yuan pondered for a moment, tasted it, nodded, and said, "Not bad, professional level."

Hou Xiaoyong's snail noodle cooking skill is at level 1, which is much better than his crime scene investigation skill.

Hou Xiaoyong smiled and squatted next to Jiang Yuan, introducing, "Cooking snail noodles is simple, but the order needs to be controlled. For example, this oil, it's not interesting if it's cooked for too long, and peanuts should be added later, otherwise they won't be crispy..."

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

"Jiang Ge, should we process the crime scene later?" Hou Xiaoyong asked.

Jiang Yuan glanced at him and said, "I can handle it myself."

Processing the crime scene is also to verify Jiang Yuan's own ideas, and on the other hand, to see if there are any more clues.

Similar to many crime scenes he had processed before, the probability of finding any trace in a scene that had already been processed once is very low. If something is found, it is usually just a trace.

Moreover, this scene had been invaded by the villagers who had gathered around during the initial stage, so the value of the evidence was greatly reduced.

In view of this, Jiang Yuan didn't expect anyone else to help.

And even if he wanted someone to help, Jiang Yuan would rather ask Heizi for help than Hou Xiaoyong.

Hou Xiaoyong looked disappointed and lingered at the door. He didn't want to go in and whispered, "Jiang Ge, I actually want to learn something from you, to learn from you..."

"You won't learn anything from me. You're thinking too much." Jiang Yuan ruthlessly interrupted Hou Xiaoyong.

"You don't have to teach me, I'll just stand here and watch."

"You can watch, but there's no need." Jiang Yuan took a deep breath. "Crime scene investigation is a meticulous job, and there are no martial arts secrets. Moreover, it's very unlikely to find any evidence at the scene today."

Hou Xiaoyong looked disappointed.

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

However, in Jiang Yuan's opinion, a player at level 0.6 still has the opportunity to practice, so there is no need to forcefully learn.

Even if Jiang Yuan doesn't cheat, with a few months of practice, he can reach the level of a professional player, starting at level 0.9. A player at level 0.6 is definitely a player with a reverse talent.

The requirements for crime scene investigation are not high. Having sharp eyes, being meticulous, patient, having some ideas, and having some associative ability are basic. But it seems that Hou Xiaoyong doesn't have any of these.

It doesn't matter though. He is still a good child of his mother and a good baby of society. He's just not suitable for crime scene investigation.

Recognizing reality early and changing to a different position may be more reliable for Hou Xiaoyong.

"By the way, where is forensic Ye? Who is doing the autopsy?" Jiang Yuan finished eating the snail noodles and asked.

"Wang Lan, forensic Wang." Hou Xiaoyong said.

Jiang Yuan secretly thought to himself, as expected.

For the recent homicide cases in Qinghe City, Wang Lan is involved in at least half of them, but for the homicide cases in Longli County, Wang Lan is almost always present.

There may be clues on the body, but if forensic Wang Lan hasn't found anything, the autopsy is put in second place by Jiang Yuan.

Patting his stomach, Jiang Yuan went to relieve himself and then came back to change clothes for the crime scene investigation, also driving most of the people away.

Wang Zhong assisted him, diligently dipping the brush in powder, taking photos...

Click, click, click.

Jiang Yuan calmly conducted the crime scene investigation, and his movements gradually became relaxed and rhythmic.

Whether he can find anything or not is one thing, being elegant is what matters.

Hou Xiaoyong watched by the door for a while, didn't understand, wanted to wait for Jiang Yuan to look over, but couldn't wait and left.

In the evening.

After completing the crime scene investigation, some human hair and more traces of searching the scene were found.

From this perspective, the element of burglary has been strengthened.

After all, if it was done by someone familiar like a husband, there would be no need to steal their own belongings. Moreover, there would be no need to search so many places, which would only prolong the time of the crime and make it easier to be discovered.

However, it cannot be ruled out that someone familiar intentionally confused the situation. Or perhaps, the husband hired aliens who wanted to earn some extra income and searched everywhere.

After properly handing over the evidence to the evidence room in Longli County, Jiang Yuan went to their video office.

There are many ways to find a thief who broke into a house, but surveillance is the most reliable.

Mobile phone tracking can also be used, now it's very convenient to locate through base stations, but this method usually only proves that someone was at a certain place, it's good for investigation, but not enough for evidence.

For ordinary burglaries, the police are too lazy to use this method. They have to find the technical investigation experts, and then they have to search for evidence again, which is like licking a bitter gourd on both ends. If used in the wrong place or for the wrong purpose, it's a waste.

It can be hard to make great work when its stolen from bit.ly/3iBfjkV.

Of course, the more traditional methods of finding fingerprints or DNA evidence such as hair and sweat are also good options. It just tests the ability of the crime scene investigator, and on the other hand, using this method to catch a thief who has been caught once, often grows after coming out of prison.

Through wearing gloves and coveralls, one can often perfectly avoid leaving such evidence. However, the possibility of leaving sweat still exists. The thicker the clothing, the greater the likelihood of sweating during the crime, and it depends on whether the crime scene investigators can find it.

Under normal criminal investigation circumstances, the police force's efforts towards burglary are just average. They actually prefer the "pulling up the radish and bringing out the soil" approach, which is to wait.

Otherwise, it's often the case that they trace back through the stolen goods.

Compared to that, finding the suspect through surveillance is a very effortless way of solving the case.

Hou Lejia looked a bit excited. Seeing Jiang Yuan, he whispered, "There have been a series of burglaries recently. And in most cases, bicycles and electric bikes have been stolen. It should be the work of the same person."

"Stole bicycles and electric bikes to carry things?"

"Yes, he usually steals and finds the keys at the same time, then loads up larger items like computers, and takes the bicycle or electric bike. If he can't find the keys, he should be able to pick the lock."

Most repeat offenders have a similar crime pattern.

It's like ordinary people going to work. After a while, what time to get up in the morning, which route to take, which bus to take, all become a fixed pattern.

Criminals working is also like going to work. Even if they want to evade punishment, they can't always think about changing.

They don't have that strong innovative ability.

If they could come up with new ideas at any time, they would have become capitalists long ago. Who would have time to commit burglary?

A successful criminal often reinforces his crime pattern, because if it works every time, he will definitely think his crime pattern is advanced.

Similar examples can be found in Japanese adult films, where even the rhythm of the action doesn't change in the same series, just the female lead changes.

"Did you capture the suspect on surveillance video?" Jiang Yuan asked directly.

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

Moreover, burglars don't need to be so cautious. It's not like there's a death every time.

Hou Lejia nodded, had his subordinate play the video, and said, "There are other videos being reviewed, there should be more later."

As he spoke, a shadow appeared on the screen.

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

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

"We're still trying to figure it out." Hou Lejia was relatively confident.

As long as the surveillance captured it, there are still many ways to continue looking for the person.

Jiang Yuan checked the time, it was already 10 p.m. If he delayed any longer, he would definitely have to pull an all-nighter.

Jiang Yuan simply said, "Give me a computer, I'll adjust the image."

Recently, I've been chewing on ginseng while writing, and the effect is quite good. Gradually, I can taste a hint of sweetness from the dry ginseng... Today I found that I've eaten half a jar of ginseng, and I feel like I've eaten a bit too much, so I put a piece under my tongue tonight, and the effect seems to be not bad...
