When Du Dayong led three people to the crime scene, it was already dark.
After getting off the car, Du Dayong looked around. It was around seven o'clock in the evening, and it was still very lively here.
"You get off the car and circle around the scene first, see how many of the ten households are at home now, and see how much traffic there is on the Zhengjiazhuang road or on the paths. The scene is still here, but the scene is still there.
Everything around us changes at any time, which is very important for us criminal police officers.”
When the three people heard this, their scalps exploded. Is this the realm of masters? Why did we want to move the equipment down and enter the site immediately as soon as we arrived!
"Bring your notebooks and don't crowd around the crime scene. The east-west direction here is very short, but the north-south direction is very long. Each of you walks along the north-south road to observe. It extends five hundred meters to the north and one to the south.
Fifteen hundred meters.”
"I'm observing step by step along the east-west path. It's now 7:20, and every half hour the north-south paths alternate from east to west until 10:30. Tang Wei and Li Xiaohui are in a group, and I
Team up with Fu Cheng."
After Du Dayong finished speaking, he walked away calmly.
Even though Fu Cheng had been in the criminal police brigade, no one had ever asked him to do this on the spot.
Du Dayong also knew that there must be people from the Dongjiao police stationed at the scene of the crime, and everyone knew that it was very likely that the suspect would stay here again.
What Du Dayong could also feel was that it was almost impossible for the suspect to return to the scene.
Du Dayong also has his own judgment. After all, it has been more than two months since the crime occurred. If the suspect is really not far away, if he wants to observe the crime scene, he should come within a week.
Once it exceeds a month, the criminal suspect himself will ignore such a problem, let alone more than two months now.
Today's squatting and surveillance are more like buying lottery tickets. There is only hope, but more often there is no hope at all.
The four of them wandered around like this until half past ten, before they gathered at the crime scene again.
It's Fu Cheng's business to open the door, because he has the key to this rental house.
However, before entering the crime scene, Du Dayong received a call from Wu Zhengping.
"Dayong! Why did you go to the crime scene so late? Did you find any new clues?"
As soon as the call was connected, Wu Zhengping's urgent voice came.
"Hello, Captain Wu! Let's take a look at the crime scene and see if we can get any new insights! There are really no new clues. If there are any, I will definitely report it to the team and you."
Du Dayong is definitely not able to sing two songs on the same mountain now.
"Dayong! Your kid is almost a sperm now. Haha! I'm not trying to trick you. I've already discussed it with your Li team. No matter who breaks through, half of the family will do it."
"Team Wu! Don't worry, as long as you discuss it with the leader, I will definitely have no objections. As long as there is a breakthrough in the case, I will definitely inform you after I report it to the leader."
"Okay! I won't make it difficult for you front-line criminal police. Now, it doesn't matter which one is broken. The key is to seize the time to break it. You also know that the weather is getting hotter. If you don't hurry up and break it,
If so, the people here will have too much to worry about."
"Team Wu! I will definitely do my best."
After Du Dayong hung up the phone, he also shook his head. He was now sitting in the position of a small leader and knew that leading a team was not easy.
"Are you all dressed? Don't touch anything after you get in."
The three people quickly responded yes!
After entering the room, Du Dayong did not turn on the light, but asked Fu Cheng to hold the equipment, the purple light.
He, Li Xiaohui, and Tang Wei all held strong flashlights.
"Is the power strip strap long enough?"
Du Dayong's first question after entering was to ask Fu Cheng.
"Captain Du! That's enough! It's about ten meters!"
"Let's shine the light from the inside to the outside of the house little by little. Fu Cheng first took the purple light to the bedside, making sure that the wires don't touch anything."
Fu Cheng slowly placed the wires on the wiring board and slowly moved the purple light closer to the bedside.
Du Dayong asked Li Xiaohui and Tang Wei to turn on the strong flashlights.
There was an obvious light difference between yellow-white light and purple light, but none of the three people knew what to look at.
Du Dayong, however, stared closely at the bedside.
"There is dust in the room. When the room is no longer occupied, the dust will slowly begin to adhere to the objects. You can see that as long as it leaves a mark on the bedside that night, after the dust falls, there will be no traces.
The imprinted area must have an extra layer of accumulated dust than the imprinted area.”
"I'll hold the purple light, and the three of you will take turns looking at it."
After Du Dayong said that, he handed the flashlight to Fu Cheng, and then took the purple light from Fu Cheng's hand.
Fu Cheng started to read it slowly, but after looking at it for a long time, he didn't know why.
Du Dayong then asked Li Xiaohui and Tang Wei to take a look at it, and they were also confused.
"Have you noticed that although the headboard is purple, there is one area that is the cleanest. So that area must be where the victim's head and hair are when sleeping. Which direction is the thinner dust?
"
"On the right!" "On the right!"
The two female generals said it immediately.
"That's right! Because the victim has long hair, the direction to get up is to the right."
"On the cornice of the bed, there are obvious wiping marks, especially on the left side of the bed. There are also obvious wiping marks, but there are none on the right side. What does that mean? It means that the suspect got out of bed from the left.
.What does that mean?”
When Du Dayong said this, he turned his head and looked at these three people.
