Chapter 438 Calmness (seeking a monthly ticket)

Changxin Village.

The incoming vehicles, one after the other, circled the southeast of the village and stopped at every turn.

Seeing Lie Xinxi's villagers come out to collect parking fees, they were called aside for education.

Two technicians from the criminal investigation team, together with Lao Ye, the forensic doctor, entered the courtyard at the southeast corner and never came out again. Their brows relaxed when they saw Jiang Yuan.

"Come in and have a look, the scene is a bit miserable."

When Lao Ye saw that Jiang Yuan had really come, his spirit changed.

Ever since he entered the scene, he kept asking Hou Le's family to invite Jiang Yuan over, not only because he was not confident, but also because the momentum of the scene was different.

Although Lao Ye's ability is limited and his level is average, he has been doing forensic work for so many years, and he has been to many scenes.

Some of the crime scenes created by criminals can be seen by novices, while others can be seen as not simple.

Jiang Yuan changed into protective clothing and other equipment and entered, and saw bloodstains appeared from the position of the door.

"He went in? Did the murder weapon stay?" Jiang Yuan saw the blood on the ground and the wall and knew that it was cut with a relatively sharp and heavy long knife.

As far as this judgment is concerned, it is already the trace tool inspection of LV6, and the bloodstain analysis of LV5.

"I didn't keep it, I looked for it specially." Lao Ye was a little regretful.

This is also one of the signals of veterans. Many novice murderers like to leave the murder weapon at the scene, because it is troublesome to hold something in their hands when running, or they are afraid that with the murder weapon in their hands, it is easy for passers-by to find out and call the police. I even felt that the murder weapon was taken away, and I didn't know what to do with it.

In fact, any way of dealing with it is better than leaving it on the spot.Because in any murder case, even with Jiang Yuan's ability, it is difficult for him to confirm the type of murder weapon in the first place, let alone the specific appearance. The initial judgment basically depends on guessing.

In the later stage, in order to ensure the integrity of the chain of evidence, the police will also spend a lot of effort to find the murder weapon, and the investigation of criminal cases is, in essence, a duel of resources between the police and the robbers.

Consuming more police resources theoretically reduces the risk of arrest.

Of course, ordinary criminals will not consider this step at all, because if they consider this step, they should know that it is more beneficial to reduce the investment of the police not to commit high-violence crimes and not to create tragic scenes.

But most criminals tend to do the opposite.In the final analysis, when they choose to commit a crime, the factor of confrontation is inflated.

In front of Hou Le's family, Forensic Ye continued: "It feels very calm. You see that there is so much blood, there is not even a bloody footprint on the ground. There is more blood inside, and I didn't step on it."

"Indeed." Jiang Yuan agreed, walking along the paved bridge while looking around.

The house in Changxin Village was newly built in recent years.The large courtyard at the entrance is paved with anti-corrosion wood. The four-story building is not too big, but there is a porch on the first floor. After walking around, there is a large living room with floor-to-ceiling windows, which looks atmospheric and bright.

Of course, now there is a lot of blood spilled on the ground, the upper body of the male owner is spread on the floor-to-ceiling windows, and the waist is almost cut off. The design of the living room is a bit unrecognizable, but the foreign style index has risen.

There were still no bloody footprints on the bloodstain in the living room.

Jiang Yuandao: "The murderer escaped while hiding the blood left behind. He was indeed very calm."

Although it is said that when cutting on the spot, there will not be as much blood gushing out as now, but to avoid this blood, you still have to be extra careful.

Paying extra attention means that the murderer is relatively calm at this time.This alone is not easy. A normal murderer, regardless of how well he planned before, if he is not a repeat offender, at this moment, he is definitely in a state of superiors. How about it.

One of the secrets of secret marches in ancient times is to require "a person gets the title, and the horse picks the bell", which prevents novices from shouting.

At the same time, Jiang Yuan noticed a large number of footprints in the living room, sighed, and asked, "Did any villagers come in?"

"Well, the villagers who found it ran out to shout, and some even beat the corpse with crutches." Lao Ye's face was also dark when he said this.

Wang Zhong, who accompanied the trace examiner, took photos, looked at the shape of the corpse, and said, "It's all like this, and you still can't see that someone is dead?"

"He just wants to touch it, what can you do." Lao Ye snorted, and said: "The old man in the village also has a heart to break."

The policeman at the scene said: "I made a statement for the old man on crutches and recorded it on video. He said he wanted to see if the corpse was soft or hard, so he pounded it a few times."

"The old man is in his 60s and is going to be [-]. He should be just curious." Hou Lejia's face darkened. This kind of thing is the most disgusting.

Naturally, he doesn't want to cause extra problems now, so he also has the mentality of letting things go.

"Let's go to the second floor." Jiang Yuan looked at the living room, kitchen and bathroom, and continued to go upstairs.

The second body, that is, the hostess of the house, died on the stairs on the second floor. The body was facing down, forming a pool of blood.

Further inside is the messy master bedroom, as well as the clothes and shoes in the dressing room of the master bedroom.

"I lost some cash, a little gold, and diamonds from when I got married." The two technicians other than Lao Ye were also older police officers. Hou Le's family took care of them and did not send them on business trips. More tragic scene of murder.

However, the skills of the two are not bad, and they have a lot of experience in on-site investigation, so...the two also suggested to Hou Lejia to ask Jiang Yuan to come back—if you did not scan useful fingerprints and DNA, then, instead of expecting to be scanned later, it is better to expect an on-site investigator who understands bloodstain analysis to appear.For example, Jiang Yuan.

Hou Lejia wanted to hold on longer, but the situation at the scene was not optimistic, and he didn't dare to let the gold flow away 24 hours a day.

"Take the footprints of all the people who have been to the scene, including the police and civil servants." Jiang Yuan ordered a step first, and then began to check the corpse form.

"Did you find anything?" Hou Lejia eagerly approached.

"Look at your luck." Jiang Yuan meant that if you are unlucky, you need to do a thorough investigation. If you are lucky, you can relax a bit.

From his own point of view, Hou Lejia felt a little disappointed.

If solving a case depends on luck—although he often relies on luck, it is only after relying on it that he knows how unreliable luck is.

"Sweep the scene."

Jiang Yuan didn't find any clues at the scene that could directly point to the murderer, so he could only proceed step by step.

With LV4's crime scene investigation, even if the murderer is very careful, Jiang Yuan is confident to find clues.

Even if it is a skilled crime, its level of concealment is limited.Even criminals who have been educated many times, their maturity is very slow.

This is mainly because the cost of training is too high.If you practice three or four times on average, you will go to prison once. It is very difficult for a criminal to have a higher proficiency level than the police.

In addition, criminal behavior is also a competitive behavior. From this point of view, criminals with generally low education levels are likely to be at a disadvantage compared to police officers with generally higher education levels, especially criminal officers.

Especially in some serious crimes where everyone is very serious, criminal officers with theoretical guidance always perform much better than criminals without theoretical guidance.

The latter is really living by luck.

"Bring me some more cotton swabs and evidence bags." Jiang Yuan said while sweeping.

Hou Lejia was looking at the house like a headless chicken, but immediately walked over when he heard the words, and asked, "Did you find anything?"

"There are sweat stains in this jewelry drawer, which may have been left by the criminal." Jiang Yuan pointed to the edge of the jewelry box.

In the drawer with light-colored wood grain, two drops of suspected sweat stains can be seen, which is not easy to detect.Jiang Yuan was also holding a drawer for jewelry, and looked through it carefully before confirming one place.

The victim's master bedroom was thoroughly turned over, including some winter quilts.Coupled with the fact that two people had just been hacked to death, the criminal was relatively excited, and sweating was almost certain.

The victim's jewelry was placed in the drawer under the closet. At this time, there were still some large jewelry packaging inside, and the rings, necklaces, etc. inside were all gone.

This kind of drawer is actually not easy to disassemble. The criminal most likely lowered his head to pick up the jewelry one by one into his pocket.

And resting after strenuous exercise, it is easy to sweat.

Wang Zhong brought more cotton swabs and small evidence bags, Jiang Yuan moistened the cotton swabs on the spot, and knelt down to pick up the sweat stains.

Looking at this scene, Hou Le's family was both happy and a little inexplicably sad. With such a large expenditure, if he saved a few more years, he might even buy a private jet. That's it?
