The red light spot is so penetrating that when you look out from the darkness, your vision immediately becomes blurry.
Liu Sheng covered his eyes and raised the flashlight and waved it twice before the red dot on the opposite side moved.
"There are too many cameras, and those who didn't know it thought they were targeted by snipers." Liu Sheng walked to the door and couldn't help complaining.
"There is no harm in having more evidence." Liu Jinghui agreed with Tao Lu's arrangement. Although it may not be useful in the court stage, when facing the scene, the ironclad evidence is like the "mountain" in the mountain, which is really meaningful.
Liu Sheng muttered, not really objecting to anything, but stood there a little dull.
There was basically nothing for him to do. This place was very remote, and it was impossible to go back, so he could only stay there.
Liu Jinghui walked up and down, and when inspiration burst out in his mind, he stood next to Liu Sheng, thinking hard.
Looking at the two people standing across from each other, I feel that their eyes are out of focus, but one person's brain is spinning crazily, and the other person's brain is lying flat.
Jiang Yuan first walked through the three floors, then returned to the first floor and began to change clothes and gloves.
Liu Sheng seemed to come to life at this time and asked quickly: "How is it?"
"There is a lot of evidence, and the evacuation was not in a hurry, but there was not much evidence cleared, and there was basically no systematic cleaning." Jiang Yuan said and glanced at Liu Jinghui.
Liu Jinghui was also activated instantly and frowned: "That means this is probably not the first scene."
The deceased Zhang Lizhen fell into the water nearby, and the pollen information on her body also showed that she had entered this courtyard, but this does not mean that Zhang Lizhen must have died in the yard.
Maybe he died outside the yard, or maybe he died outside on the grass or under the woods.
Judging from logical reasoning, the police followed the information about Zhang Lizhen's body and found the house here. And such a good house with obviously high cost was abandoned, and the calculated time was close to the time of Zhang Lizhen's death. So, Zhang Lizhen's
The relationship between death and the house is bound to be inseparable.
Based on common sense, in this case, if Zhang Lizhen died in the house, it would be the most normal idea to do some cleaning to remove the evidence.
Therefore, if there are no traces of cleaning in the courtyard, it is very likely that the first scene is not in the courtyard, making cleaning unnecessary.
Of course, there is another possibility that the person in charge of the house did not know about Zhang Lizhen's death. However, based on common sense, it is difficult to believe that the person in charge of such a remote and special house would have such weak control ability.
On the other hand, even if the person in charge of the house did not know that Zhang Lizhen was dead and therefore did not clean the house, the murderer should return to the scene and clean it.
Liu Sheng also came back to his senses, thought for a while, figured it out, and asked further: "Actually, even if this is not the first scene and nothing happens, isn't it normal to clean it up?"
"Your question is very interesting. The person in charge has time to take away the picture frames and the like, why don't you clean the room?" Liu Jinghui paused and said: "There are two reasons, either because he feels it is not necessary, or
I feel it is necessary.”
"No need to clean up? Someone has died. This reason is obviously inappropriate." Liu Sheng said.
Liu Jinghui nodded.
Liu Sheng continued: "Necessary means that the person in charge feels it is necessary to leave evidence?"
Liu Jinghui nodded slowly: "That's the only way to explain it."
The two of them looked at Jiang Yuan as they spoke. They were showing off their reasoning here, but in the final analysis, the truth must be supported by evidence.
Jiang Yuan waved to a policeman with a camera, and then brought a spotter to start the investigation from bottom to top.
"First take the footprints on the ground." Jiang Yuan asked someone to turn on the survey light and then take the footprints one by one.
Soon, the investigation lights were turned on in the dark room.
For now, Jiang Yuan believes that the value of footprints is very great.
Footprints can not only determine a series of identity characteristics of the people present, but most importantly, they can see whether there was any struggle, resistance, dragging, etc. at the scene.
People are easy to die but difficult to kill. Even if the deceased is a woman, it is not easy to kill her cleanly. Although the previous reasoning and discussion have already been in favor of the first scene not being indoors, it still needs to be seen.
Moreover, behaviors such as fighting and dragging are seen because they are different from ordinary and are more intense activities.
For Jiang Yuan, as long as there are footprints, less intense activities can actually be seen.
He has now developed the crime scene reconstruction (temporary +1) skill, which is equivalent to LV5 crime scene investigation. At the same time, he has a more advanced specialty item equivalent to LV6 crime scene reconstruction.
At this level, as long as you are willing to invest time and energy, you can not only see how and where the owner of the footprints walked, but you can even see what the owner of the footprints did before and after he landed.
A simple example, when there are traces of left and right twisting on a footprint, it means that the owner of the footprint may have turned.
Many human movements must have a foothold. As long as the ground conditions are good enough, these can be seen. However, the house has been closed for more than a year, and the accumulated dust has become...
Conducive to footprint identification.
Jiang Yuan and others first built a Banqiao to collect and record the footprints layer by layer.
At the same time, while others were taking the footprints, Jiang Yuan did another round of analysis, and then went around several more footprints and observed in a spiral.
I picked up some hair or dander and the like, and marked and photographed them separately.
For Jiang Yuan, the on-site survey itself is not difficult, but to organize it well, not only the survey stage must be methodical and organized, but also the later investigation stage, and even the litigation stage, must be provided with powerful information at any time.
Evidence support is the most difficult part.
As you can imagine, there were a lot of people living or visiting this house. To extract them all in an efficient and orderly manner would require a lot of work.
Three floors, going up one level after another, and then coming down to collect evidence, it was already dark.
After taking the footprints, take fingerprints and classify the various traces.
Normal on-site inspections do not actually do this. They usually only take key fingerprints and traces at key locations.
Otherwise, this electronic age would be just that. 20 years ago, when paper materials were popular, the size of evidence would have become a problem.
This time's scene is different. Tao Lu and others, including Tao Lu, tend to obtain as much evidence as possible and target as many people as possible.
This work continued until night, and then most of the current survey work was completed.
Compared with the situation indoors, there are no valuable clues in the yard. More than a year in the woods and more than a year in the city are completely different concepts.
With so many microorganisms and all ecological niches fully filled, it is difficult to find fingerprints and footprints in the courtyard, let alone use them to prove anything.
"Tao Zhi, the on-site investigation is complete." When Jiang Yuan took off his gloves again, it was already dark.
"The work of fingerprint identification and footprint identification has also been left to you?" Tao Lu asked.
Jiang Yuan nodded: "It can be done."
"Okay, then I'll join the dog."
Forensic doctor Jiang nodded again.
Tao Lu took out his walkie-talkie and said, "Let the dog in."
Several fat and strong police dogs immediately appeared in front of Jiang Yuan and others.
