Chapter 21 The Blood on the Door

Liu Wangcai's reaction was very intense.

Zhou Ning didn't seem to notice, hung the camera around his neck, found the scissors from the survey box, and stood beside the chair.

Xu Dayuan waved his hands, and two policemen stepped forward, grabbed one hand each, handcuffed Liu Wangcai's hands, and then pressed Liu Wangcai's wrists hard.

Zhou Ning leaned forward, brushed the scissors twice, the gauze was cut on the back of the hand, Liu Wangcai clenched his fist, and the gauze was pinched in the palm, so that even if the gauze was pulled out, the wound would be damaged.

Zhou Ning raised his head and looked at Liu Wangcai who was writhing like a maggot.

"Your current actions will be recorded by surveillance. Are you guilty of reacting like this? Only by checking the wound can you prove your innocence, so don't make unnecessary struggles. This will only make you more suspicious."

Zhou Ning's voice was not loud and his speech speed was not fast, but Liu Wangcai didn't move for a moment, as if he felt that what Zhou Ning said was reasonable, and seeing that he was not struggling, the two policemen let go of their hands, and they retreated panting.

It is not difficult to see from the state of the two policemen that Liu Wangcai is very strong, which does not match his figure.

Zhou Ning was not in a hurry. Liu Wangcai, who was loosened, slowly loosened the gauze in his hands. Xu Dayuan glanced at Zhou Ning appreciatively, waved to the two policemen, and the two went out. There were only three of them left in the interrogation room. indivual.

Zhou Ning gently pulled the gauze, because he just squeezed it hard, the wound oozes blood again, so the gauze bonded to the wound is not so tight, he gently lifted it with tweezers, and the wound was exposed.

Liu Wangcai suffered extensive abrasions on his hands. Among the bloody wounds, he could see a cut on the inner surface of his right thumb, which was not covered up by the abrasions and skin damage.

The cut was very deep. Zhou Ning raised his camera to take a picture, and found a small scab on his left palm, hidden in the damaged abrasion wound.

Zhou Ning handed the camera to Xu Dayuan, grabbed the scab with tweezers, and put it directly into the evidence bag. His movements were smooth and smooth, and Liu Wangcai was a little dazed.

"Xu Da, I'll go and compare, and I'll report back to you later."

Xu Dayuan nodded, and Zhou Ning left with his things.

He took three steps at a time and went straight up to the second floor, and entered the photos just now into the comparison software. This time, he didn't have much time to wait, and a comparison result popped up with a snap.

The palmprint collected on the handle of the murder weapon overlapped 80% with Liu Wangcai's palmprint. Zhou Ning punched hard.

The scratches look terrible, but if they are not deep, they will not affect the palm prints. They can overlap by 80%, and they are still close to the interface between the thumb and index finger, so it can be concluded that Liu Wangcai is the murderer.

However, it is hard to say whether the court will accept this evidence. If such evidence is handed over, the dossier may be returned. If there is other evidence to cooperate, it will be more perfect.

Zhou Ning sent a message to Xu Dayuan, and Xu Dayuan pushed the door in after a while.

"Compared?"

Zhou Ning nodded vigorously.

"There are 80% overlapping traces of the palm prints. This evidence is not solid. Xu Da, I want to go to the first scene and Lan Taizi to see."

"Lan Taizi? What are you doing there?"

"Xu Da is like this. The female deceased, Zhu Meifeng, was starved for more than 48 hours before she died, and there was no restraint injury on her body, so I think she must have been locked up somewhere. Since Liu Wangcai knew that they had been to Lantaizi, he may will also go.

Furthermore, Liu Wangcai can think of using an unfamiliar number to come back and contact me. I think he is very likely to find a foothold nearby. Didn’t you say that this Lantaizi is not far from the village, and it is secluded and very suitable for hiding. You can look for it . "

Xu Dayuan smiled and patted Zhou Ning on the back.

"Let's go and have a look. Let's not miss any possibility. It's better if we can find it. If we can't find it, we'll wait for the news from Ludong City and the report from yesterday's inspection. After all, we won't have a letter until the afternoon. .”

"Don't worry Xu Da, I'll call you as soon as I find out."

after an hour.

Zhou Ning closed his eyes and sat in the back row. Zhao Xinli's car was fast, and Xiao Liu was in the co-pilot. He didn't dare to make any movement. Xu Da said, let Zhou Ning take a good rest on the road. I can think of something useful to solve the case.

But Zhou Ning didn't sleep, because when he closed his eyes, the large transparent screen lit up in front of his eyes. When the countdown was 48:00 hours left, it flickered for a while, as if it was full of joy, and the brightness of the size was not the same. grade.

In this way, wouldn't it be blinding in the remaining 24 hours?
Zhou Ning was a little speechless. Today he took the initiative to say this to Xu Dayuan. The biggest reason was the countdown. This thing looked terrible, and with the brakes shaking the car stopped, Zhou Ning's eyes also opened.

The view 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. The houses are built with big stones and covered with blue color steel tiles.

Zhou Ning got off the car, Zhao Xinli and Xiao Liu carried a camera on their backs, and the other carried a reconnaissance box. The reef here needs to go up all the way, and it is not easy to walk. Take a closer look.

Zhou Ning stood on a high place, did not rush to look at the stone houses on the terrace, but stood on the edge of the stone steps he climbed up, and observed carefully.

"There seems to be a black spot in the gap, have you seen it?"

Zhao Xinli and Xiao Liu shook their heads together.

"Xiao Zhou's forensic doctor, this reef is black, how can you tell it apart? I didn't see the black spots you mentioned, so I thought they were all black."

Zhao Xinli slapped Xiao Liu on the back of the neck with such force that Xiao Liu was stunned.

"Brother Zhao, why did you hit me?"

"Hitting you is light, do what you are asked to do, stop talking nonsense, Xiao Zhou's forensic doctor has found out, then we will do as ordered, are you professional, or is he professional?"

Xiao Liu became wilted, Zhou Ning waved his hand, held up the luminol reagent and sprayed it, but there was no fluorescent reaction, so he stood up.

"I'm wrong, please help me observe carefully, although this is a black reef, but the black of the stone is gray, if there is blood, it is purple black.

If according to my previous deduction, the murderer took Zhu Meifeng to hide here after killing Li Delin, then the wound on his hand would definitely leave traces here. "

Zhao Xinli was taken aback.

"How do you know that the murderer was injured? Xu Da didn't say anything?"

Xiao Liu curled his lips with dissatisfaction, but he didn't dare to resist. Zhou Ning was a special protection group, Zhao Xinli couldn't beat him, and his qualifications couldn't match him, so he could only mutter.

"Aren't you also questioning?"

Zhao Xinli rolled his eyes.

"Come on, I'm just seeking knowledge. If you don't understand, just ask. I'll understand next time. I didn't see the small notebook on the door of my car. I have experience in many cases."

Zhou Ning glanced at Zhao Xinli in surprise, and looked at Zhao Xinli's chubby face. It turned out that he was the one with a heart. It was impossible not to ask Zhou Ning, and he was willing to tell.

Thinking of what Xu Da and his grandfather said about withdrawing the county and changing the district, will the forensic room also be expanded?

Zhao Xinli didn't know that Zhou Ning was playing with him, and smiled obsequiously at Zhou Ning. Zhou Ning didn't hold back, and laughed.

"Don't worry, I'll tell you when I ask, I'll give you a bottle of this luminol reagent each. I saw the houses on Lantai, all of which have wooden doors, some are tied with wires, some are hung with chain locks, and the door handles are all Spray the luminol reagent and see who finds the fluorescent door first."

Both Zhao Xinli and Xiao Liu were very happy. After all, they were young. When they usually investigated, they mostly looked at them, and there were very few things they could do. They were either guarding or moving along. It was quite interesting to spray this.

"to make."

Saying that, the three of them separated, one by one 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 it was all rotten. walk between.

The second room looked very new, with a red chain lock on the door, and the new one did not have a trace of rust. Zhou Ning paused. A small window with a length of 1.7 centimeters, the window is covered by the ceiling, and the outside cannot be seen.

Zhou Ning raised the luminol reagent in his hand. Before spraying it, he saw a smear of red on the inside of the door handle. Zhou Ning touched the handle, and the chain shook a bit. A vertical bloodstain appeared on the handle on the chain. under the lock.

Zhou Ning took a deep breath and shouted loudly:
"Come on, I found the blood!"
