Chapter 21 Blood on the Door

Liu Wangcai's reaction was very intense.
Zhou Ning seemed not to see it. He hung the camera around his neck, found a pair of scissors from the investigation box, and stood next to the chair.
Xu Dayuan waved his hand, and two policemen stepped forward, each grabbing one of Liu Wangcai's hands, and handcuffed both of them directly, and then pressed down Liu Wangcai's wrists hard.
Zhou Ning came closer and cut the gauze on the back of his hand with two scissors. Liu Wangcai clenched his fist with the gauze held in his palm, so even if the gauze was pulled out, the wound would be damaged.
Zhou Ning raised his head and looked at Liu Wangcai, who was wriggling like a maggot.
"Your current actions will be recorded by the surveillance camera. Are you feeling guilty for reacting like this? Only by checking your wounds can we prove your innocence, so don't struggle in vain. This will only make you more suspicious."
Zhou Ning's voice was not loud and his speech was not fast, but Liu Wangcai stopped moving instantly, as if he felt that what Zhou Ning said made sense. Seeing that he did not struggle, the two policemen let go of his hands and retreated panting.
It is not difficult to see from the condition of the two policemen that Liu Wangcai is very strong, which is inconsistent with his body shape.
Zhou Ning was not in a hurry. Liu Wangcai slowly loosened the gauze in his hand. Xu Dayuan glanced at Zhou Ning with appreciation and waved to the two policemen. The two went out, and there were only three of them left in the interrogation room.
Zhou Ning gently pulled the gauze. As he had just squeezed it hard, the wound started bleeding again, so the gauze that was glued to the wound was not so tightly attached. He gently lifted it with tweezers, and the wound was revealed.

Liu Wangcai had large areas of abrasions on both hands. In the bloody wounds, a cut could be seen on the inner side of his right thumb, which was not covered by the abrasions and skin damage.
The cut was very deep. Zhou Ning raised his camera to take a picture and found a tiny scab on his left palm, hidden in the broken abrasion.
Zhou Ning handed the camera to Xu Dayuan, picked up the scab with tweezers and put it directly into the evidence bag. His movements were so smooth that Liu Wangcai was a little confused.
"Xu Da, I'll go and compare it and report back to you later."
Xu Dayuan nodded, and Zhou Ning left with his things.
He took two steps at a time and rushed straight up to the second floor. He entered the photo into the comparison software. This time he didn't have to wait long. With a click, a comparison result popped up.
The palm prints collected from the handle of the murder weapon overlapped 80% with Liu Wangcai's palm prints. Zhou Ning punched hard.
The abrasions look horrific, but they are not deep and will not affect the palm lines. There is 80% overlap and they are close to the interface between the thumb and index finger, which shows that Liu Wangcai is the murderer.
However, it is hard to say whether the court will recognize this evidence. If such evidence is submitted, the file may be returned. It would be perfect if there is other evidence to support it.
Zhou Ning sent a message to Xu Dayuan, and a moment later Xu Dayuan pushed the door open.
"Did they match?"
Zhou Ning nodded vigorously.
"There are 80% overlaps in the palm prints. This evidence is not very solid. Xu Da, I want to go to the first scene and Lan Taizi to take a look."
"Lantaizi? What are you going there for?"
"Xu Da, this is the case. The female victim, Zhu Meifeng, was starved for more than 48 hours before her death. There were no restraints on her body, so I think she must have been imprisoned somewhere . Since Liu Wangcai knew that they had been to Lantaizi, he might have gone there too.
Besides, Liu Wangcai thought of using an unfamiliar number to contact me. I think he is very likely to find a place to stay nearby. Didn’t you say that Lantaizi is not far from the village and is secluded and very suitable for hiding? We can go and look for it.”
Xu Dayuan smiled and patted Zhou Ning on the back.
"Okay, let's go check it out. We shouldn't miss any possibility. If we can find it, that's great. If not, we'll just wait for news from Ludong City and the report sent in yesterday. After all, we won't get any news on either until the afternoon."
"Don't worry, Mr. Xu. I'll call you as soon as I find anything."
after an hour.
Zhou Ning sat in the back seat with his eyes closed. Zhao Xinli's car was driving very fast. Xiao Liu was in the passenger seat and dared not make any noise. Xu Da said that Zhou Ning should have a good rest on the way because his brain was precious and he might be able to think of something useful that would help solve the case.
But Zhou Ning did not sleep, because when he closed his eyes, the large transparent screen lit up in front of him. When the countdown reached 48:00 hours, it flashed for a long time, as if with joy, and the size and brightness were not at the same level.
At this rate, won’t the remaining 24 hours be blinding?
Zhou Ning was speechless. The biggest reason why he took the initiative to talk to Xu Dayuan today was because of this countdown. This thing looked terrible. With the shake of the brakes, the car stopped and Zhou Ning opened his eyes.
What you see outside the window is a reef, not a beach. There is a row of stone houses on the reef. In fact, they are all made of local materials, with large stones built up and covered with blue colored steel tiles.
Zhou Ning got off the car. Zhao Xinli and Xiao Liu, one carrying a camera and the other carrying a survey box. The reefs here require climbing up all the way and are not easy to walk on. After the three of them climbed up, they found that the view here is wide, which allows them to have a panoramic view of the village.

Zhou Ning stood on a high place and did not rush to check the stone houses on the Lantai. Instead, he stood on the edge of the stone steps and observed carefully.
"There seems to be a black spot in the gap. Do you see it?"
Zhao Xinli and Xiao Liu shook their heads together.
"Mr. Zhou, this reef is black. How can I tell it apart? I don't see the black spots you mentioned. I think it's all black."
Zhao Xinli slapped Xiao Liu on the back of his neck with such force that Xiao Liu was stunned.
"Brother Zhao, why did you hit me?"
"Beating you is a light punishment. Just do what you are told to do. Stop talking nonsense. Xiao Zhou, the forensic doctor, has made a discovery. We just need to follow his instructions. Are you a professional, or is he a professional?"
Xiao Liu was dispirited. Zhou Ning waved his hand, raised the luminol reagent and sprayed it. There was no fluorescent reaction, so he stood up.
"I must have seen it wrong. Please help me observe carefully. Although this is a black reef, the black of the stone is tinged with gray. If there is blood, it would be purple-black.
If according to my previous inference, the murderer killed Li Delin and took Zhu Meifeng to hide here, then the wound on his hand must have left a mark here. "
Zhao Xinli was stunned.
"How do you know the murderer was injured? Didn't Xu Da tell you?"
Xiao Liu curled his lips in dissatisfaction, but did not dare to resist. Zhou Ning was a specially protected person, he could not beat Zhao Xinli, and he was not qualified to compete with him, so he could only mutter.
"Aren't you questioning that, too?"
Zhao Xinli rolled his eyes.
"Don't give me that. I'm seeking knowledge. If I don't understand something, I'll ask. I'll understand it next time. Didn't you see the little notebook on my car door? I've followed many cases and I have experience."
Zhou Ning glanced at Zhao Xinli with some surprise. Looking at Zhao Xinli's silly fat face, he realized that he was the one with a thoughtful mind. It was impossible for him not to tell Zhou Ning after he asked, and he was willing to tell.
Thinking about what Xu Da and Grandpa said about abolishing the county and changing it into a district, does the forensic room also need to be expanded?
Zhao Xinli had no idea that Zhou Ning was plotting against him, and he smiled at Zhou Ning in a flattering manner. Zhou Ning couldn't help but laugh too.
"Don't worry, I'll tell you when I ask. I'll give each of you a bottle of this luminol reagent. I looked at the houses on the terrace. They all have wooden doors. Some are tied with wire, and some are chain-locked. The door handles are all sprayed with luminol reagent. Let's see who finds the door with fluorescent reaction first."
Zhao Xinli and Xiao Liu were both very happy. After all, they were not very old and usually they watched mostly during investigations and rarely got to do anything. They were either on guard or helping with the moving and lifting. It was quite fun to spray this.
"become."
As they spoke, the three of them separated, one person in a row, and began to search on the reef.
Seeing the two of them running away, Zhou Ning walked alone to the door of the first stone house in the middle row. This stone house had no door or roof and was completely rotten. Zhou Ning glanced at it and walked straight to the second house without stopping.
The second room looked very new, with a red chain hanging on the door. It was brand new without a trace of rust. Zhou Ning paused. The door was tightly closed. There was a small window ten centimeters high and forty centimeters long on the edge of the south wall, which was 1.7 meters high. The window was blocked by the ceiling and one could not see outside.
Zhou Ning raised the luminol reagent in his hand, but before he sprayed it, he saw a hint of red on the inside of the door handle. Zhou Ning's hand touched the handle, and the chain shook. A vertical line of blood appeared on the handle below the chain.
Zhou Ning took a deep breath and shouted loudly:
"Come on, I found the blood!"
