Chapter 411: Calmly

Changxin Village.

Incoming vehicles, one after another, parked around the southeast of the village, finding every available space.

Some villagers who saw the opportunity to make money came out to collect parking fees, only to be called aside and educated.

Two technicians from the Criminal Science Team, plus Wu Wu Fa Yi Old Ye, entered the courtyard in the southeast corner and did not come out again until they saw Jiang Yuan, at which point the brows of several people finally relaxed.

"Come in and take a look; the scene is a bit miserable."

Seeing that Jiang Yuan had really come, Old Ye's spirit was different.

Ever since he entered the scene, he had been constantly asking Hou Lejia to invite Jiang Yuan over, not only because he lacked confidence, but also because the atmosphere of the scene was different.

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

Some crime scenes created by criminals, at a glance, you know it's the work of a novice, while others, at a glance, you know it's not simple.

Jiang Yuan changed into protective clothing and other equipment and entered. He saw that bloodstains appeared starting from the door.

"Killed their way in? Was the murder weapon left behind?" Jiang Yuan knew from the bloodstains on the ground and the wall that this was done with a sharp, heavy, long knife.

Just this one judgment was already Lv6 trace tool inspection and Lv5 bloodstain analysis.

"Didn't leave it; specifically looked for it." Old Ye was a bit regretful.

This was also one of the signals of an experienced hand. Many novice murderers like to leave the murder weapon at the scene because it is troublesome to hold something while running away, or they are afraid that holding the murder weapon will be easily discovered and reported by passersby, or they don't know how to deal with it.

In fact, any way of dealing with it is better than leaving it at the scene. Because for any homicide case, even with Jiang Yuan's ability, it is difficult to confirm the type of murder weapon at the first time, let alone its specific appearance; initial judgments basically rely on guessing.

And in the later stages, in order to ensure the integrity of the chain of evidence, the police will also spend great efforts to find the murder weapon, and the investigation of criminal cases, in essence, is a resource confrontation between police and bandits.

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

Of course, ordinary criminals don't consider this step at all, because if they considered this step, they should know that not committing high-violence crimes and not creating tragic scenes is more beneficial in reducing police investment.

But most criminals tend to do the opposite. Ultimately, when they choose to commit a crime, the factor of confrontation is already expanding.

Wu Wu Fa Yi Ye said in front of Hou Lejia: "A very calm feeling. Look, so much blood flowed, and there isn't even a bloody footprint on the ground. There is even more blood inside, and it hasn't been stepped on."

"Indeed." Jiang Yuan agreed, walking inside along the laid-out wooden bridge while observing the surroundings.

This house in Changxin Village was built in recent years. The large courtyard at the entrance was paved with anti-corrosion wood, and the four-story building was not large in area, but the first floor was set up with an entrance hall, and after bypassing it, it was a large living room with floor-to-ceiling windows, looking atmospheric and bright.

Of course, there was a lot of blood spilled on the ground now, and the male owner was lying on the floor-to-ceiling window with his upper body, his waist almost severed, and the design sense of the living room couldn't be seen, but the "foreign" index was rising.

On the bloodstains in the living room, there were still no bloody footprints.

Jiang Yuan said: "The murderer walked while avoiding the blood left behind. It really is very calm."

Although, when hacking and killing at the scene, the blood that bursts out won't be as much as it is now, but avoiding this blood still requires extra attention.

Extra attention means the murderer's state at this time is relatively calm. Just this point is very difficult. Normal murderers, regardless of how well they planned before, if they are not repeat offenders, at this very moment, they are absolutely in a "hot-headed" state. Whether they shout out or not is one thing, but they can't care about what happens afterwards.

One of the secret manuals for secret marching in ancient times was to require "people to hold chopsticks in their mouths, horses to remove bells," to prevent novices from getting hot-headed and shouting loudly.

At the same time, Jiang Yuan noticed a large number of footprints in the living room and sighed, asking: "Have villagers come in?"

"Yes, the villager who discovered it ran out to call people, and someone even used a crutch to poke the corpse." Old Ye said this, and his face was black.

Wang Zhong, who came along as a trace examiner, took photos and looked at the shape of the corpse, saying: "It's already like this, and they still can't tell the person is dead?"

"People just want to touch it; what can you do." Old Ye hummed and said: "Old men in the village, there are also bad-hearted ones."

The police officer at the scene said: "We took a statement from the old man with the crutch and recorded it. He said he wanted to see if the corpse was soft or hard, so he poked it a few times."

"The old man is nearly seventy; it should just be curiosity." Hou Lejia's face was black. This kind of thing is the most disgusting, belonging to the type that is not easy to handle, and disgusting if not handled.

He naturally didn't want to create extra trouble now, so he also had a mentality of avoiding trouble.

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

The second corpse, the female owner of the house, died at the stairs on the second floor, the corpse face down, forming a pool of blood.

Further inside was the master bedroom, which was turned upside down, and the floor of the master bedroom's changing room was covered with clothes and shoes.

"Cash was lost, there was a little gold, and there were diamonds from the wedding." The two technicians other than Old Ye were also older police officers. Hou Lejia took care of them and didn't send them on business trips, but didn't expect to encounter a more tragic homicide.

However, their technology was not bad, and their experience in doing scene investigation was also very sufficient, so... the two also suggested to Hou Lejia to invite Jiang Yuan back—if you didn't scan any useful fingerprints and DNA at the beginning of the crime scene, then instead of expecting to scan them later, it's better to count on a scene investigation who understands bloodstain analysis. For example, Jiang Yuan.

Hou Lejia wanted to persist for a while longer, but the situation at the scene was not optimistic, and he didn't dare to let the golden 24 hours flow away.

"Take the footprints of everyone who has been to the scene, including police and civil servants." Jiang Yuan instructed first, and then began the corpse surface examination.

"Any findings?" Hou Lejia leaned over anxiously.

"Depends on luck." Jiang Yuan meant that if luck is bad, a large-scale investigation is needed, and if luck is good, it will be easier.

Hou Lejia was a bit disappointed from his own perspective.

If solving the case depends on luck—although he often relies on luck—it is precisely because he relies on it so much that he knows how unreliable luck is.

"Scan the scene."

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

Using Lv4 crime scene investigation, even if the murderer is very careful, Jiang Yuan has the confidence to find clues.

Even if it is a skilled crime, its concealment level is limited. Even for criminals who have studied multiple times, their maturity is very slow.

This is mainly because the cost of training is too high. If you have to go to prison after practicing on average three or four times, 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 are likely to be at a disadvantage compared to police officers with generally higher education, especially criminal science personnel.

Especially in the state of serious crimes where everyone is very serious, criminal science personnel with theoretical guidance always perform much better than criminals without theoretical guidance.

The latter truly live by luck.

"Give me a few more cotton swabs, and evidence bags." Jiang Yuan said while scanning.

Hou Lejia was looking around the room like a headless fly, and when he heard this, he immediately walked over and asked: "Any findings?"

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

In the light-colored wood-grained drawer, two suspected sweat stains could be seen, which were not easy to detect. Jiang Yuan also held the drawer containing the jewelry and looked at it carefully before confirming one spot.

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

And the victim's jewelry was placed in the drawer at the bottom of the wardrobe. At this time, some large jewelry packaging remained inside, but the rings, necklaces, etc., inside were gone.

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

And after strenuous exercise, it is easy for sweat to fall.

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

Hou Lejia watched this scene, both happy and a little inexplicably sad. He had such a large expense, and if he saved for a few more years, maybe he could buy a private jet, and this is it? ===== CHAPTER 412 =====
