Chapter 466 Clean the rooftop

It was useless that Zhou Ning went over, and Da Zhao had already run over with a brick.

Zhou Ning took a closer look and saw that the brick in Da Zhao's hand was similar to the broken bricks thrown on the roof. They all carried moss and looked very old, but dark brown blood could be seen beside the moss.

"Very good, keep looking for it. There are a lot of miscellaneous items on the roof. I checked it inch by inch. Which direction is the surveillance targeted? Where was the body finally found?"

Da Zhao found a hand-drawn picture, and you could tell at a glance that it was in the car. Liu Yufei asked He Hongjian to tell the story. They drew it and compared the direction. Da Zhao pointed to the eastmost side of Building 2 on the north side of the guard and said:

"This No. 2 camera is installed on the east wall of Building 2. According to He Hongjian, the video record given by the police is the picture of this camera. However, after identification, the shoes were dropped. He Hongjian's wife discovered the shoes in the morning.

As for the body, it fell on the west side of Building 3, and was blocked by a row of attached rooms below and fell into the small open space. In the morning, someone wanted to open the attached door to get the electric car, and only then did he find He Jiahong's body."

"That is, is it right if there is no camera facing the west side of Building 3 and the attached room?"

Da Zhao nodded.

"There are three cameras in total. One is across the road from the doorman, facing Building 1, and the other is also in that position. It is just facing several unit doors in Building 2. Even if someone passes below, it is not clear."

Zhou Ning walked towards the west side of the platform. There was no blood on the ground here. The deceased's head was damaged and blood was left on the bricks. But nothing was discovered at the scene. Could it be that this was not the first scene?

"Have you checked carefully? Have you sprayed luminol reagent?"

Da Zhao sighed.

"I have checked it all. I have used seven bottles of luminol reagent. I found a drop of blood on this edge. I don't know what Lao Yang has found."

Lao Yang shook his head. Zhou Ning knew before coming that if a professional person participated in concealing or forging the scene in this case, it would be very difficult during the investigation process. However, he still didn't expect that there was nothing useful.

"I didn't find anything else, but I used test strips to test it. On the door handle on the top platform and the road heading west, there was a large area of ​​chlorine-containing disinfectant. According to the traces left on the ground, it was carefully washed here."

As Lao Yang pointed, Zhou Ning followed quickly to squat down to check. Sure enough, the handle on the west side of the door handle was darker, close to the edge of the south side, there were uniform traces left by brushes on the ground, all of which were fan-shaped traces, extending to the rainwater outlet on the west side.

Lying on the edge of the roof, Zhou Ning looked down and the rainwater pipe was broken four meters away from the ground. It seemed that it was in disrepair.

"When you go down the high-speed rail, let the driver Lao Wang find you a ladder, go up from below, and see if there are any splashes in the rainwater pipe, especially for blood and various liquids, and take samples. As for the locations above and the locations that have been washed, Lao Yang and Da Zhao will also take samples."

Sun High-speed Railway ran down quickly, and Lao Yang was a little puzzled.

"Didn't the boss say that after scrubbing with 84 disinfectant, the blood stains and DNA will be destroyed. What's the point of collecting?"

Zhou Ning shook his head.

"Among the chlorine-containing preparations, 84 disinfectants are the easiest to obtain. Indeed, it can clean up blood stains and destroy DNA and proteins, but it only causes protein denaturation in DNA. However, DNA fragments can still be extracted, and of course, such fragments can be compared."

When they heard this, both of them were a little excited. Da Zhao slapped his head and suddenly remembered.

"I remembered that the figure skating team doctor used this method before, and we still found the DNA in the residue, but it was a sewer and there were a lot of things hanging, this one."

Lao Yang pulled Da Zhao away. Zhou Ning didn't know that there were few traces left here, but it also showed a problem. Perhaps this was not the first scene of the persecution of the deceased.

Zhou Ning called Xiaoqu's phone number, and the other party answered the second time.

"Director Zhou, don't worry, the surveillance has been deleted, the technique is very professional, I am trying to recover, but it takes a little time. As for the video sent by Director Zhong, I watched the Wuqibahei, and something really fell off at 23:37. After slowing down, I can confirm that what He Hongjian said is true. This is a shoe."

"Well, then hurry up and recover. Have you seen the school surveillance?"

"I saw that the situation was basically the same. I deleted the saved monitoring original file. And I found that there was a corner of the monitoring, which happened to be able to capture a corner of the salt industry community. I don't know if it was a subsequent adjustment or it has been like this. I am working hard to recover."

"Okay, let me know."

After saying that, Zhou Ning hung up the phone. At this time, Da Zhao and the others had finished sampling. They lay on the edge of the platform and looked down at Sun Gaoshi. He had climbed to the position where the rainwater pipe was broken. This guy was even more cruel. He did not use a swab to collect it, but directly scraped the paint on the surface of the building with a knife. It seemed that after a while, the paint was scraped into a large piece, and the finishing box in his hand was almost half filled.

Zhou Ning rubbed his nose, and it seemed that he would go down quickly, otherwise this guy could peel the wall from there to the first floor.

"Da Zhao hurried down and told Sunshine to collect some. If you peel them down, all the residents here will complain."

Da Zhao looked puzzled and glanced at him, almost sucking.

"This kid is OK. I will use this trick next time. It will be easy to find any residue."

Zhou Ning glared at him, and Da Zhao ran away happily.

Lao Yang looked sad and pulled off a layer of gloves. The strong chlorine-containing preparation tasted pungent.

"Boss, the sampling has been completed, but I looked at it and it seems that it was not the first scene. The incident happened on March 28th.

The lowest temperature in Xinghua City that day was minus 1 degree, and the wind was six to seventh level. How addicted is it? The cold wind on the rooftop is hehe, what are you doing?”

This sentence reminded Zhou Ning that he had thought before that since there are so many tenants in this community now, there may be one household, which is the place where the violence is really committed.

"Let's go, go downstairs first, and you can see where the deceased fell to see if there are any residues. I'll go to find Sister Fei. Xinghua Municipal Bureau has not yet provided an investigation report on the site. This process is a bit slow."

Old Yang nodded, followed Zhou Ning, carrying the survey box and a box full of samples, and quickly went downstairs.

On the way, Zhou Ning looked at it. Except for the second-floor western home rented by He Hongjian, the other houses did not change the original style of the security door. Some of the doors were covered with the characters of Fu and couplets, and the walls were filled with small advertisements, such as water access, moving, unlocking, and repairing home appliances. They were all kinds of advertisements.

As soon as he went downstairs, he saw Liu Yufei coming. Zhou Ning quickly followed Liu Yufei to a place where no one gathered.

"Neither Xinghua Municipal Bureau nor Director Zheng came here, nor did he send an investigation report?"

Liu Yufei shook her head.

"I called and said that someone was sent to me immediately, but Director Zheng said that he had gone to a company and called the police continuously. He called 110 six or seven times in the morning. I heard that a mentally ill rushed in and committed the murder, carrying a knife to chop people everywhere."

Zhou Ning took a look at the time, and it was only 12:07 at this time.

"I called the police six or seven times, which means I started calling the police very early. This person drank very early. Is this breakfast?"

Liu Yufei frowned and nodded slightly. It was obvious that the authenticity of the police was self-evident. At this time, we could see that No. 5 Middle School began to get off school, and people wearing school uniforms walked into the community one after another.

At the same time, a police car drove straight in, and the sirens roared maniacly, which attracted everyone to look over. Several half-aged children were running and jumping in the community. Even if the parents pulled them, they were almost scratched by the car.

A policeman cursed and seemed to accuse the woman who was taking care of the child. Her hands were stretched out, her fingers turned into palms, and she grabbed the child's head and teased her for a while.

Then he held a file bag and searched for the target. In fact, Liu Yufei was easy to recognize. The woman was wearing a police uniform and had such a strong aura. She found that Liu Yufei was running close to her and handed the file bag to Liu Yufei.

"Sorry, Liu Da, I delayed the road for a while. I am Liu Mo, the deputy captain of the criminal police team of Xinghua Municipal Bureau. This case was determined to be suicide, so there is not much information left and it is not easy to find. This is an investigation report."

Zhou Ning glanced at the deputy captain of the criminal police team, who looked in his thirties. Although he was anxious, he had a smile on his lips, and the smell of smoke was covered with a corner of Huazi's pocket. The police uniform jacket was temporarily put on, and the collar was turned inside. There was dust on the seat belt on his right shoulder.

It seemed that he was deliberately delaying. He smoked cigarettes on the road, and it was such a high-end cigarette. The police car was very new, but no one used the passenger seat belt and was sent to contact the superior task force. He looked so careless. This person was definitely not an ordinary person.

Liu Yufei took a look and then handed the file bag to Zhou Ning.

Zhou Ning looked through it and found that the survey report was so simple that it was outrageous. There were only two pages in total. The first page was the survey discovery and the survey results were also the results. There was a lot of nonsense, and the useful one was just one sentence.

After on-site investigation, it was found that there were footprints of the deceased stepping on the edge of the platform on the roof. No suspicious objects were found at the scene. There was no abnormality around the deceased's death. It was determined that the deceased committed suicide and died. The investigation time was March 29, 2013.

The page behind is a hand-drawn scene picture. The top floor is on it, and there is also the position of the footprints. A comparison photo of the footprints and the soles of the deceased's shoes is clamped. The bottom is a picture of the death position of the deceased. A photo is also pasted. The deceased lying on his back on the ground, his arms stretched straight at a 45° angle toward the south side, and the corpse zombie is very obvious.

Zhou Ning opened the file bag and searched for it.

“No autopsy report?”

Liu Mo slapped his head, as if he had just remembered it, and quickly turned around and ran towards the police car, took out another file bag from the back seat, and ran back again.

"Look at my mind, I just thought about the survey report and forgot what Dr. Zhang gave me."
