Chapter 244 Bloodstain

I have to say that this person speaks too artistically.

From the look just now, it was obvious that they were looking for familiar personnel from the Tongshan Sub-bureau or the Beizhai Police Station. This is a department directly under the local area.

How could Xu Dayuan fail to understand such an extended meaning, so Xu Dayuan glanced at him with his hands behind his back.

Zhou Ning didn't look at him, but raised his eyes to look at the top of the building. There was a spherical shape shining on the top. There seemed to be a circle of metal around the edge of the top, presumably it was something like a lightning protection belt.

"Is your person in charge here? I'm not referring to the department manager, but the person in charge of the group. Our city criminal police detachment received a report and started a second investigation into the case of Zhang Yinan's fall from the building.

Call and ask him to explain the situation. Of course, the relevant personnel from the police station and sub-bureau who have been investigated and questioned before should also come here. Please find a big office. "

Xu Dayuan's words made the man obviously startled, and he was about to speak, but Xu Dayuan raised his hand at this moment.

"Another thing I want to say is, from now on, don't leave my sight. Xiaobai goes to the monitoring room. The manager Liu Yufei calls on hands-free. You bring a police officer to record. Everyone he notifies, Name, contact information and position are all recorded one by one.

The people in the second group, called the person in charge of security of Guanghai Pharmaceutical Group, went directly to the top floor to conduct a second survey of the scene of the fall, and turned on all the law enforcement recorders for me, so as not to miss anything. "

Zhou Ning didn't move, Da Zhao waved directly to the person next to him who was holding a mobile phone and wanted to make a call. He had already noticed that this person was winking at the security guards, and everyone obeyed. Obviously this is the head in charge of security.

"My manager, you don't need to call. Later, your president and everything will be investigated and questioned. You can rest assured that you will know about it. Come and follow us to the top floor."

The man glanced at the manager who stopped Xu Dayuan just now, the manager didn't speak, what could he say, now the situation is completely controlled by the police, and no news can be sent out.

Da Zhao pushed the security manager with a smile on his face.

"What's your name, manager?"

"My name is Zhu Dongjie. I'm either a manager or the security captain."

With such an explanation, the purpose is self-evident, and Da Zhao nodded with a smile.

"Let's go, Captain Zhu."

Seeing that no one stepped forward to stop him, Zhu Dongjie knew that he couldn't hide now, touched his pocket, and was about to move forward.

Da Zhao pinched his sleeve with two fingers, Zhu Dongjie paused.

"What's wrong?"

"It's nothing, just to remind you, don't get to the top floor after wearing all the keys, and then you find that the door is locked and you don't have a key. It's boring to say an excuse. Of course, if you don't have a key, we can also go up with tools. , let's not waste time twice, and don't waste time."

Zhu Dongjie's face darkened, and he waved his hands behind him. Someone handed over a keychain with a circle of keys attached to it. The people in the second group followed Da Zhao and Zhu Dongjie and went directly into the lobby of the building.

As soon as they entered, they saw many people in the hall stop and look at them, whispering to each other, as if they were talking about something.

A few people walked to an elevator room in the corner, took the elevator, went straight to the 22nd floor, got off the elevator and walked to the end of the corridor, entered the corridor and walked to the top. It was indeed a double door with a thick chain hanging on it, which was entangled. Lots of circles.

Zhu Dongjie stepped forward and unlocked the chain, Da Zhao pushed the door open, and at the same time looked back, there was no surveillance here, which is why Chen Wenchi called the police at that time, but there was no relevant evidence.

Because it is impossible to prove how Zhang Yinan got to the top floor, and whether anyone went up with her.

Several people came to the top floor platform, the floor was covered with floor tiles, there were even gazebos, umbrellas, tables and chairs, and many landscape shapes, just like a hanging garden.

"So anyone can come up here?"

Zhu Dongjie nodded.

"It used to be a small park for rest. When the weather is good, many employees of the group like to have lunch here. You can see the mountains and the sea from a distance, and the air is fresh. It was only because of the jumping that the top floor was closed. .”

Seeing Zhu Dongjie put his hands in his pockets, Da Zhao smiled at him.

"Don't send messages or make phone calls, and of course don't record anything. It's meaningless to contact right now. Your pants are too thin. You can see them when the screen lights up. I have a law enforcement recorder on me. If there is any objection, we can provide a video of the whole process.”

Zhu Dongjie took out his hand and said nothing.

Xiao Qu held up a camera and turned around on the spot. He was doing scene inversion, which can be simulated later. Zhou Ning glanced at it and waved to Yang Xuetong and Da Zhao.

"Survey the middle edge position on the north side."

The two of them moved over with their suitcases, and the wind was very strong here. Although it felt sunny and sunny when they were on the ground, standing here, it felt like a wind of force four or five.

There are traces of scrubbing on the ground. There is a fence about 1.2 meters high and nearly one meter wide at the edge of the building. There is a fence above the fence. There is a protruding metal outside the fence. Obviously, this is the combination of lightning protection belt and decoration.

However, Zhang Yinan is only 160 tall. At this height, it is very difficult for her to go up directly. The tables and chairs under the parasol next to her are completely fixed, and there is more than two meters away from the wall, so she cannot use her strength at all.

Zhou Ning supported the wall with both hands, and he had already stood up. Zhu Xingxing covered his mouth to prevent himself from screaming, and Da Zhao and the others climbed up the wall on the other side.

However, Da Zhao's hands were firmly grasping the fence, his face was a little pale, the height was very scary, and the vehicles below looked about the size of a matchbox.

Zhou Ning walked towards Da Zhao from where he was, and Da Zhao had already climbed down backwards, waving at Yang Xuetong.

"Brother, go and see the fence. I'm really afraid of heights. After looking at it twice, my legs are weak now."

Zhou Ning waved his hand at this time and reached out to Yang Xuetong.

"Give me a magnifying glass and luminol."

Yang Xuetong handed Zhou Ning the magnifying glass, and at the same time climbed up, tied a safety rope around Zhou Ning's waist, and threw the other end to Sun Gaotie and the others.

Zhou Ning glanced at the position below, corresponding to the orientation of the flower bed, closed his eyes and thought about the fall site drawn by Chen Wenchi, Zhou Ning took a step back and looked at the top of the fence.

Carefully look for information that may remain on the fence. It has been nearly three years since February 2009, 2. If Zhang Yinan was thrown off the top floor, the place will definitely be cleaned carefully, so Zhou Ning mainly observes the outside of the fence. Various gaps.

After all, the fence is made of wrought iron, which is not as glamorous as stainless steel, and the twisted neck of the deceased was dislocated, and the murderer put her in any position at will.

But there is a problem with this. If a normal person is scratched, he will subconsciously avoid it, and if he is on the verge of death, he will not have this reaction.

Because the deceased Zhang Yinan had a bruise on the back of his right hand, Zhou Ning didn't want to understand the origin of these bruises at the time, when he saw the fence, the first thing he thought of was that bruise.

Just when Zhou Ning took another step back, he found that the outer edge of the fence seemed a little dirty, so he blew it, Zhou Ning sprayed the luminol reagent, and then blocked the strong light with his hand, a faint fluorescent light appeared.

Seeing Zhou Ning's actions, Da Zhao quickly handed over a swab dipped in distilled water.

"Zhou Xiaozhou will give you a swab!"

Zhou Ning took samples three times in a row, and took pictures afterwards, but he didn't come down, Yang Xuetong had already climbed up at this time, and was at the side to check carefully, Da Zhao shouted at Yang Xuetong.

"Old Yang, slow down, you are much fatter than Zhou Xiaozhou, and the people behind are a bit strenuous to hold you!"

Yang Xuetong snorted twice. At this time, he also found something on the edge of the fence at the bottom. On an iron barb, he picked up a triangular piece of leather with tweezers, and looked at Zhou Ning with bright eyes.

"The team leader, I found this. I remember that the deceased was wearing a red down jacket and a sweater skirt, with black tights and short boots underneath, but there was no leather defect on the boots."

The two jumped off the wall. Zhou Ning raised the magnifying glass and took a closer look. The inside of the leather fragments was black and hard, while the pores on the front were evenly distributed and shiny. His eyelids twitched.

"Bloodstains! Pack it up and mark it. It looks like a leather glove. The material is very soft, but the inner leather is a little stiff. It may be the bloodstain left by the murderer."

Sun Gaotie hurriedly held up a physical evidence bag and put the things into it. Da Zhao tilted his head and stretched out his hand to gesture for the location.

"That is to say, someone was standing by the fence, holding on to the last railing, and wanted to go up, but the quality of the wrought iron was not good, it pierced a glove, and a piece of leather was hung off. He climbed up the fence, and then put the Someone pushed it down the stairs?"

Zhou Ning nodded.

"One hand grabbed the fence and went up, but the other hand was carrying the deceased. Unfortunately, the clothes of the deceased were not found. It is probably because of the leather gloves. When the deceased was carried up, the cervical spine was misaligned, and he was in a near-death state. .

There is a saying, dead heavy, dead heavy, although the deceased was only 110 catties, but wearing such heavy clothes, it is not easy to carry a person up a 1.2-meter wall with one hand, so he did not pay attention to whether he was injured or not. "

Several people nodded vigorously. After all, there was progress, and everyone was very happy.

After jumping off the fence, the security captain was carried by two economic investigation experts, his eyes were a little erratic.

After the accident, it is estimated that they have redecorated the platform. After all, there are traces of freshly painted on the edge of the wall, and even the tiles on the ground may have been laid later.

But the wrought iron fence on the top is not easy to replace because it is combined with a lightning protection belt, and they didn't think about it. The gaze of the security captain Zhu Dongjie said everything.

Many of them know it!

"Call Xu Da and take this Captain Zhu Dongjie away, he is an insider!"

Da Zhao called Xu Dayuan, and was about to speak, but Xu Dayuan hurriedly said:
"Hurry up and come down to the twentieth floor, Wang Guanli wants to see Zhou Ning!"
