Changxin Village.

One after another, foreign vehicles surrounded the southeast of the village and stopped wherever they could.

Some villagers who were excited to see the prey came out to collect parking fees and were called aside for education.

Two technicians from the criminal department, plus the forensic doctor Old Ye, entered the yard in the southeast corner and never came out again. Until they saw Jiang Yuan, the brows of several people were relaxed.

"Come in and take a look. The scene is a bit tragic."

Old Ye saw that Jiang Yuan really came, and his spirit was different.

Since entering the scene, he kept asking Hou Lejia to invite Jiang Yuan over, not only because he was not confident, but also because the momentum of the scene was different.

Although Old Ye has limited ability and average level, he has been doing forensic work for so many years and has seen many scenes.

Some crime scenes created by criminals, you can tell that they are the work of novices at a glance, and some are not simple at a glance.

Jiang Yuan changed into protective clothing and other equipment and entered, and saw blood stains starting from the door.

"Killed in? Did you leave the weapon behind?" Jiang Yuan knew from the bloodstains on the ground and the wall that it was done with a sharp, heavy long knife.

This judgment alone is already LV6 trace tool inspection and LV5 bloodstain analysis.

"No, I looked for it specifically." Old Ye was a little regretful.

This is also one of the signs of a veteran. Many novice murderers like to leave the weapon at the scene, because it is troublesome to hold something in their hands when running away, or they are afraid that if they hold the weapon in their hands, it will be easy for passers-by to find it and call the police, or even feel that they don't know what to do with it if they take it away.

In fact, any way of handling it is better than leaving it at the scene. Because for any homicide case, even with Jiang Yuan's ability, it is difficult for him to confirm the type of weapon in the first time, let alone the specific appearance. The initial judgment is basically based 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 weapon, and the investigation of criminal cases is essentially a resource duel between the police and the criminals.

Consuming more police resources, in theory, reduces the risk of being arrested.

Of course, ordinary criminals will not consider this step at all, because if they consider this step, they should know that not committing highly violent crimes and not creating tragic scenes are more beneficial in reducing police investment.

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

In front of Hou Le's family, Forensic Doctor Ye continued: "It feels very calm. Look, there is so much blood, but there is not even a bloody footprint on the ground. There is more blood inside, and no one stepped on it."

"Indeed." Jiang Yuan agreed, walking along the paved plank bridge while observing the surroundings.

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

Of course, there is a lot of blood on the ground now. The male owner's upper body is spread on the French window, and the waist is almost cut off. The design of the living room is a little invisible, but the foreign style index is rising.

There are still no bloody footprints on the bloodstains in the living room.

Jiang Yuan said: "The murderer left by avoiding the blood left behind. It was really calm."

Although it is said that when the scene is hacked and killed, the blood that bursts out at once will not be as much as it is now, but to avoid the blood, you still have to be extra careful.

Paying extra attention means that the murderer is in a relatively calm state at this time. This alone is very difficult. A normal murderer, no matter how well he planned before, if he is not a repeat offender, is definitely in a state of excitement at this moment. It's better not to shout out, and who cares about what happens afterwards.

One of the secrets of secret marches in ancient times is to require "people to hold their mouths and horses to remove bells", which is to prevent novices from getting excited and shouting.

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

"Yes, the villagers who found the body ran out and shouted, and some people even used crutches to hit the body." Old Ye's face was also dark when he said this.

Wang Zhong, who came with the trace inspection, took photos and looked at the shape of the body, and said: "It's like this, can't you tell that the person is dead?"

"People just want to touch it, what can you do." Old Ye snorted and said: "Old men in the village have bad hearts."

The police at the scene said: "The old man with crutches made a confession and recorded it. He said he wanted to see whether the body was soft or hard, so he hit it a few times."

"The old man is in his sixties and almost seventy, he should be curious." Hou Lejia's face was dark. This kind of thing is the most disgusting. It is the type that is difficult to deal with, and it is disgusting if it is not dealt with.

Naturally, he doesn't want to cause trouble now, so he is in a state of mind to keep things quiet.

"Go upstairs." Jiang Yuan looked at the living room, kitchen and bathroom, and continued to go upstairs.

The second body, that of the hostess of the house, was found dead at the staircase on the second floor, face down, forming a pool of blood.

Further inside, the master bedroom was in a mess, and the dressing room in the master bedroom was full of clothes and shoes.

"There is cash, a little gold, and a wedding diamond." The other two technicians, besides Old Ye, are also older police officers. Hou Lejia took care of them and did not send them on business trips. Unexpectedly, they encountered a more tragic on-site murder.

However, the two's skills are not bad, and they have sufficient experience in on-site investigation, so...they also suggested to Hou Lejia to ask Jiang Yuan to come back-if you don't scan useful fingerprints and DNA at the beginning of the crime scene, then, instead of expecting to scan them later, it is better to expect a on-site investigator who knows bloodstain analysis. For example, Jiang Yuan.

Hou Lejia wanted to hold on for a little longer, but the situation at the scene was not optimistic, and he did not dare to let the gold flow away for 24 hours.

"Take the footprints of everyone who came to the scene, including police and civil servants." Jiang Yuan first reminded him, and then began to do a superficial examination of the body.

"Did you find anything?" Hou Lejia came up eagerly.

"It depends on luck." Jiang Yuan meant that if the luck was bad, a large-scale investigation would be necessary, and if the luck was good, it would be easier.

Hou Lejia felt a little disappointed from his own perspective.

If solving a case depends on luck - although he often relies on luck, it is because he relies on it more that he knows how unreliable luck is.

"Scan the scene."

Jiang Yuan did not find any clues that could directly point to the murderer at the scene, so he could only follow the routine.

Using the LV4 crime scene investigation, even if the murderer was very careful, Jiang Yuan was confident that he could find clues.

Even if it is a skilled crime, its concealment level is limited. Even if it is a criminal who has been trained many times, its maturity is very slow.

This is mainly because the cost of training is too high. If an average of three or four times of practice means one has to go to jail once, it is very difficult for a criminal to have a higher level of proficiency than a police officer.

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

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

The latter are the ones who really rely on luck to survive.

"Give me a few more cotton swabs and evidence bags." Jiang Yuan said as he swept.

Hou Lejia was looking at the house like a headless fly. Hearing this, he immediately walked over and asked, "Did you find anything?"

"There are sweat stains in this jewelry drawer. It may be left by the criminal." Jiang Yuan pointed to the edge of the jewelry box.

In the light-colored wood-grained drawer, two drops of suspected sweat stains can be seen, which are not very easy to find. Jiang Yuan also took the jewelry drawer and looked through it carefully before confirming one.

The victim's master bedroom was turned over thoroughly, including some winter bedding. In addition, the criminal was relatively excited because he had just killed two people, and sweating was almost certain.

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

This type of drawer is actually not easy to disassemble. The criminal probably lowered his head and picked up the jewelry one by one into his pocket.

And it is easy for sweat to fall when you are resting after intense exercise.

Wang Zhong brought more cotton swabs and small evidence bags. Jiang Yuan wet the cotton swabs on the spot and half-knelt to remove the sweat stains.

Hou Lejia looked at this scene, happy and a little inexplicably sad. He had such a large expense. If he saved for a few more years, he might even buy a private jet. Just like this?
