Da Zhao didn't say anything, he walked downstairs quickly, Zhou Ning helped Liu Yongxin, and also climbed down from the attic.

As soon as he came down, Da Zhao was already running back out of breath.

"I asked, the small second floor in front of the Xu family was built in 2000, the couple lived downstairs, and the girl's son's room was upstairs."

The three of them went up to the second floor together, two rooms upstairs, and the middle one was a guest room, Zhou Ning walked to the room on the west side, there was a huge photo hanging on the wall, it was a family of three, it looked very happy, the child was two or three years old, and he was tiger-headed.

Zhou Ning recognized at a glance that this woman was Xu Dan, and glanced at the furnishings of the room, wardrobe, dresser, bed, desk, bookcase, these furniture are all pine, and the color has turned light brown, and there have been many years since such furniture could become such a color.

As for the floor, it was an old-fashioned pine floor, with big gaps in some places, and it looked like it had cracked after drying, Zhou Ning opened the survey box, found the luminol reagent, and began to spray carefully towards the cracks in the floor.

Of course, there is still the position of the baseboard in the corner of the wall, and he did not give up, except for the bottom of the furniture, almost all of it was sprayed, and when he got up, Zhou Ning closed the curtains, and the room went dark.

In the gap in the floor near the bed, a burst of fluorescence was very conspicuous.

Zhou Ning was overjoyed in his heart and shouted towards the door:

"Come to me!"

Liu Yongxin and Zhao Xinli ran to the door quickly, saw the blue-green fluorescence on the ground, and the two looked at Zhou Ning sharply.

"Found bloodstains?"

Zhou Ning nodded.

"The decoration around 2000 is more popular pine flooring, cheap and environmentally friendly, but this floor has a disadvantage, that is, after drying, there will be a big gap, no matter how clean the ground is, there will be blood stains in the gaps, and even under the floor I guess there will be more, help me carry the bed out."

Da Zhao Meizizi walked to the window, opened the curtains, opened the window and shouted down:

"Come up with a few people, move something."

After a while, the person who came up moved the bed out and placed it directly on the floor under the bed, Da Zhao had already sprayed luminol reagent, and sure enough, the fluorescence reaction under the bed was even more powerful.

Da Zhao looked excited.

"Isn't it, can you let Xu Ju catch this Xu Dan?"

"Fingerprint people, tell them to stop."

Zhou Ning shook his head, went to the bed next door to move out of Xu Dan's room, he lifted the sheets, and saw a bloodstain on the mattress underneath, he saw it when he moved the bed, cut it off with a blade, stuffed it into the physical evidence bag and handed it to Da Zhao, and then said.

"The evidence is conclusive, but call Xu Ju and ask him to ask the people around him, did Xu Dan have any good friends or classmates who ran away from home ten years ago?"

"Running away from home?"

Liu Yongxin kicked Da Zhao and glared directly.

"It's not that your kid has been talking so much nonsense lately, you can do whatever you want, there is no matching DNA in the missing person, that is, the family doesn't think that people are dead, so analyzed, there is no way to run away from home, of course, it may be elopement, but at this age, it is rarely done."

Da Zhao came to his senses, quickly dialed Xu Dayuan's mobile phone, and carefully repeated the discovery here, as well as Zhou Ning's words, to Xu Dayuan.

Hung up the phone and returned to the room, Da Zhao walked to Zhou Ning's side with his waist inserted.

"Xu Ju said, since you suspect that there may be more blood stains underneath, then tear down the floor."

Zhou Ning stood up, it is true that although the fluorescence reaction can be found here, it is a little troublesome to really need to extract, and the best way is to remove the floor.

"Let's call someone from the village committee to come up, it can be regarded as a witness, and then you take a picture and ask someone to find a hammer, and pick it out from this position under my feet."

Da Zhao hurriedly went to make arrangements, and Liu Yongxin glanced at the place where fluorescent traces were found on the ground.

"If the murderer is Xu Dan, she killed and divided her body alone, how did she hide in that attic? Ten years ago, Xu Dan was not big, right? ”

Zhou Ning glanced at Xu Dan's age in the notebook, if it was ten years ago, Xu Dan was 18 years old, Zhou Ning was slightly stunned.

"Ten years ago, Xu Dan was 18 years old, and the deceased was 18-20 years old when she took the college entrance examination that year, could it be her classmate?"

Liu Yongxin also came over, and this analysis became more and more reliable.

"I think about it, when I came over yesterday, I was smoking downstairs, when the village people were chatting, I listened to it, it seems that Xu Qing and Xu Dan are all fighting with each other, both of them are studying in Rudong City No. 1 Middle School, one was admitted to China Normal University with high scores, and the other was admitted to Lu Caijing.

However, when Xu Dan went to school, it seemed that he was not worry-free at school, the teacher had found parents, and it seemed that he was in early love, who was it, I didn't hear the name clearly, it seemed to be the third child of the Chen family in Qiandi. ”

As soon as he finished speaking, several policemen and members of the village committee walked in.

Da Zhao took people to tear down the floor, and Zhou Ning and Liu Yongxin dragged the people from the village committee and walked to the door of the next room.

"I'll ask you about something, was the Xu family the year of the college entrance examination? Does their family know? ”

Two people came to the village committee, the man was the village director at first glance, and the woman was estimated to be the women's director or something, the two looked at each other, the woman was silent for a moment, and then raised her head and said:

"After the Xu family's eldest sister's exam, when their family set up a banquet, I remember that a few young people came over, saying that they were classmates of the Xu family's eldest sister, and one of the parents also came with him, and someone knew him, and later heard that it was the director of Qiandi Village, whose surname was Chen Zhonghe, and his third son Chen Ningyu and Xu Dan were classmates."

Zhou Ning looked at Da Zhao, Da Zhao understood that Zhou Ning meant that he wanted to call Xu Ju, so he turned around and quickly went to make a call.

After a while, Da Zhao came back and nodded towards Zhou Ning.

"Xu Ju will come over later."

Zhou Ning didn't say anything more, put away the police pass in his hand, just now he searched Chen Ningyu's identity information, there is indeed such a person, but the ID card is the old version, the photo is blurry, it can only be seen that it is an inch head, the facial features are very thoughtful, and the details cannot be compared.

He turned upstairs, Da Zhao said a few words to the people of the village committee, and then ran upstairs, at this time the upstairs floor had been partially opened, and there were two pools of blood with a diameter of ten centimeters, and Da Zhao leaned over.

"Blood stains have been found, I will take samples first, and then find tools to directly lift the floor completely."

The men also nodded, and found a crowbar to tear open all the floors under the bed, cleaning up the broken floors on the ground, and the blood stains below were completely revealed.

A large pool of traces of blood has completely penetrated the cement floor, Da Zhao approached, directly dug down a piece of cement soaked in blood, and took a lot of samples around, and then stood up holding a piece of floor.

Wipe the broken wood chips on it and hand it to Zhou Ning.

"There is a mark here, it looks like it was left by an axe cut, it is here that the murderer killed the deceased and dismembered the body, it is estimated that there is something on the ground, but this axe still left marks on the floor."

At this time, a rush of footsteps came, Zhou Ning and Da Zhao hurriedly turned back, sure enough, Xu Dayuan came, and saw a house of messes, as well as a pool of blood on the ground, his eyes lit up, and he was about to come in, but was stopped by Liu Yongxin, and Zhang Sannian in the back also looked over.

"Don't go inside, go next door and say, only the three bedrooms on the second floor of the Xu family are paved with pine floors, this kind of floor is not hard, the water content is large, even if the paint is easy to crack, blood stains are flowing down the gap to the bottom, otherwise it is really not easy to leave traces."

Zhang Sannian came over with an excited face.

"I'll let people go now, and the two brothers and sisters of the Xu family will be arrested and brought back to the criminal police team for interrogation."

Xu Dayuan waved his hand, and Zhou Ning asked him to come over, naturally there was something else to discover, after all, there was also a director Chen from Qiandi Village on the phone.

"Don't worry, Zhou Xiaozhou came out to ask about the situation."

Da Zhao cleaned up the scene and wanted to take pictures, Zhou Ning had already come out at this time, he knew that Xu Dayuan was in a hurry, especially if he found some clues, he was even more impatient.

Before entering the next door, Xu Dayuan had already opened his mouth in the corridor and asked:

"Zhou Xiaozhou, hurry up and tell me about the survey results on your side!"

Zhou Ning talked about the attic and the discovery of the scene, of course, there was no mention of the three things that could not be compared with Xu Dan's missing fingerprints last night.

"That's the case, this room is Xu Dan's, there are photos of Xu Dan's family of three on the wall, and according to the reaction of the village committee, in 2002, Xu Dan scored well in the college entrance examination, and a student banquet was held at home, and Chen Ningyu of Qiandi Village may have a relationship with Xu Dan.

I think that Xu Dan can keep an eye on the movements on our side, even if we don't have much evidence for Xu Dan's interrogation now, we can check the Chen family's Chen Ningyu first, and I need someone to send the murder weapon and the woven bag wrapped around the murder weapon for inspection.

If a young woman is the murderer, she may also be injured in the process of dismembering the body, we have to fight for luck, after all, in this scene, there is no conclusive trace left by the murderer, even if Xu Dan is the murderer, there is no way to prove it. ”

Xu Dayuan nodded, Zhou Ning's judgment he absolutely trusted.

"I asked Liu Yufei to stare at Xu Dan and not show up for the time being, but it can be controlled at any time, Da Zhao stayed to deal with the follow-up work and find someone to send it for inspection, didn't you say that Xu Dan's fingers were missing three fingerprints, maybe it had something to do with this, Zhou Xiaozhou and Lao Liu went to Qiandi Village with me.

If the DNA comparison is successful, the identity of the deceased can be determined, but the children in the family have disappeared for so many years, don't you know to look for it? ”

Zhou Ning didn't answer, and he couldn't explain it, after all, all this was speculation, and everything had to be determined by seeing the Chen family.

......

Ten minutes later, everyone came to Qiandi Village, and under the guidance of the personnel of the Renjiazhuang Village Committee, the police car came directly to the Qiandi Village Committee.

As soon as I got out of the car, there were many people around, after all, there were so many police cars, and they were very curious, but no one dared to come up and inquire.

Xiaobai moved quickly, went in for a while, and came out with an old man with gray hair, the old man was holding reading glasses in one hand, and his face was full of doubts and fear.

Zhou Ning squinted his eyes and stared at the old man, yes is fear, his lips trembled slightly, it stands to reason that Xiaobai just asked who the director of the village committee was, and he didn't say the purpose of their coming, why did the old man react like this, is it ......

Xu Dayuan stepped forward to shake hands, and the old man smiled and stretched out his hand.

"Who are you?"

"You are Director Chen, I am Xu Dayuan from the Qindao Criminal Police Detachment, I will learn about the situation with you, is it convenient for you now?"
