As Lu Chuan just analyzed in the case analysis society, Lu Chuan felt that this was most likely not the scene of the first crime.
So if this guess is correct, the suspect dragged, moved or carried the body of the victim Wang Jingya from the car through the yard before entering the room.
What will he interact with during this process?
"Is this a plum tree?"
The distance from the doorway to the room is about 30 meters.
There is a small orchard in the yard, with several fruit trees planted in it. Now the branches are lush and full of fruits.
When Lu Chuan just came here, he saw that every household in this village probably had a small garden like this. Some of them planted some fruit trees, and some planted some vegetables.
The home vegetable garden is a standard feature in rural areas.
Just because most people in Hecun and Town have moved away, many orchards are basically abandoned.
“It’s a plum tree, it’s almost ripe.”
It is already August, and in another week or two at most, the fruits on the trees should be ripe.
After Lu Chuan nodded, he kept walking around the plum tree, carefully observing every branch and leaf on it.
Zhao Zhigao is a little strange, why is Lu Chuan holding on to this tree and not letting go?
"Lijun likes to eat plums?"
Lu Chuan shook his head.
"This tree... is in a good location."
Lu Chuan pointed to the road below the yard.
“Although this plum tree is not big, it has luxuriant branches and leaves. If we don’t hide a little bit when we come in from the outside, we may encounter this tree, right?”
Zhao Zhigao nodded. He had been in and out of the scene many times, and he had to avoid the plum tree every time. Of course he knew what Lu Chuan said was right.
“So, no, Director Zhao, if the murderer comes in and out, will he also touch this tree??”
This...
"We should encounter it."
Not should, but definitely!
Lu Chuan’s on-site investigation started with this plum tree.
The suspect has touched this tree, so it is possible that he left something belonging to the murderer on it.
Of course, this is only a possibility. The tree grows here. The policemen who came and went to investigate the case have also encountered this road, so if there is really something left on it, it is hard to say whether it may point to the murderer.
What Lu Chuan needs to do is not to miss any detail, any point, as long as there is a place or object that may intersect with the murderer, he needs to investigate and conduct trace evidence on the object. collection.
In fact, the collection of trace evidence is not the most difficult task. The key is to discover these things.
So the most important thing when collecting trace evidence is to be good at focusing on details to discover things that others cannot. You can discover clues that others cannot.
The hard work paid off, and soon Lu Chuan discovered some chemical fibers on the plum tree.
And a hair was found on a branch of the tree.
During the whole process, Zhao Zhigao said nothing and watched how Lu Chuan collected trace evidence from the plum tree.
To be honest, Zhao Zhigao admired Lu Chuan very much. First of all, he did not expect that there would be an intersection between the plum tree and the murderer.
He saw this plum tree when he first arrived at the site, and he would avoid this plum tree every time he came in and out of the site.
Lu Chuan was not in a hurry. After spending more than an hour on the plum tree, he still did not leave.
Holding a magnifying glass, Lu Chuan studied every leaf and branch from the root to the top of the tree.
Lu Chuan spent nearly three hours on the last tree. "Okay, let's go."
In fact, Lu Chuan had his own reasons for choosing this plum tree.
The murderer took care of the entire scene, but just like Zhao Zhigao did not pay attention to the plum tree, the murderer would not pay attention to the tree.
Therefore, if the police know some routine physical evidence detection locations or points, the murderer may also know them.
"When the murderer left, the yard was cleaned, right?"
Even though a few days have passed since the crime, part of the yard is obviously cleaner, and there is nothing on the ground. The messy dead branches and dry grass had obviously been cleaned in a short period of time.
But this kind of cleaning is more interesting.
Zhao Zhigao nodded: "The murderer did not clean the entire yard too much, but carefully cleaned the path it walked. To be precise, he eliminated its footprints. What he used was We didn't find it, he was probably taken away by the murderer."
This is what Lu Chuan said is the more interesting part. Although the yard is relatively clean overall, it can be clearly seen that there is a trail in the middle that has been carefully cleaned by him.
This should be where the murderer walked from the room on the road.
Some other corners are still quite messy.
When he walked to the door, Lu Chuan did not go in directly, but walked to the side room next to him.
“Wait for me.”
Just like he had just carefully inspected the plum tree, Lu Chuan carefully inspected everything in this wing.
Because Lu Chuan can be sure that the murderer must have been here.
This wing was a place where the owner originally stored firewood.
There are still some branches inside, some firewood, and some debris piled inside.
The murderer disposed of the body by cooking it.
That will definitely require a lot of dry firewood.
The other party cannot go to other places to collect dry firewood, so he will definitely use these things in the wing.
So the other party should have interacted with the firewood when getting dry firewood, so it is very likely that he will leave something belonging to him here.
Seeing Lu Chuan busy in the woodshed, Zhao Zhigao certainly understood what the other party was thinking.
Although Zhao Zhigao did not think of this when he was doing the on-site survey, he could clearly see what Lu Chuan was thinking.
To be honest, even though Lu Chuan had just arrived at the scene, he had not walked through a few places or even entered the room.
However, Zhao Zhigao had a feeling that after the entire scene was surveyed, Lu Chuan would definitely find important clues.
It seems that Lu Chuan’s idea of doing on-site investigation is completely different from his own.
Lu Chuan didn't even look at some of the points he paid attention to during the on-site survey. Instead, he spent a lot of time working on them in places he had never been to before, spending a lot of energy.
For example, a plum tree, or this woodshed.
More than an hour passed while Lu Chuan was busy inside.
When I came out, I already had four or five collection bags in my hand.
It can be seen from the expression on Lu Chuan's face that he still made some discoveries.
Of course, this does not mean that these collected things must belong to the murderer.
Because logically speaking, the family would also go to the woodshed to buy firewood before leaving, so it is possible that these things belong to the original owner. (End of chapter)
