Although Zhou Ning is very thin, he is tall and has long arms, and this height is very uncomfortable, if there is a chair outside, he can still climb in, but his figure may be thinner than the previous analysis.

Xu Dayuan looked at the bottom of the window, this is not a modern building, there are no cabinets, range hoods or anything, this window is actually the function of smoke exhaust.

So the inner and outer frames of the window, as well as the metal hook, were all thick black grease, and some of it seemed to be dripping off in the next moment.

Xu Dayuan hugged his arms and stared at the window, wondering in his heart, this is not like a state where someone climbed in?

"According to your analysis, people can indeed come in here, but if you want to get in from here, especially at this height, there must be grease everywhere on your hands, and all corners of the scene, especially the murder weapon and the deceased, have you seen grease? Or did you find the residue? ”

Zhang Chunbo and Bai Hua both shook their heads, in fact, they didn't believe this analysis at first, but after a round of investigation of the scene, except for a half-footprint left on the muddy ground and a dagger on the deceased's body, no traces were left.

Da Zhao leaned his head under the window at this time, Lao Yang supported his head, and took pictures of all the grease on the left and right sides of the window, and then Yang Xuetong sprayed luminol, but there was no fluorescence reaction around it.

Zhou Ning leaned over and looked down, all the grease was about to drip, some showed rattle marks, flowing downward, and some were stuck with dandelions and all kinds of dust, which had not been scratched or rubbed, or even touched.

This is not something you can avoid if you want to, Zhou Ning motioned for everyone to step back, raised his hand and rubbed the back of his hand on the left side, the gloves were glued with a black grease and dust, and then looked at the window and left traces.

Xu Dayuan's face was serious, he looked at Zhang Chunbo and said:

"This window is not a place for the murderer to enter and exit, it seems that the direction is wrong."

Zhang Chunbo and Bai Hua were stunned, this result and judgment made it difficult for them to accept, after all, this courtyard had been surveyed many times, and it was the most likely person to come in here, but now it was denied.

The key is that the evidence presented by the working group makes them powerless to refute, but in this case, how did the murderer get in?

Zhou Ning walked closer and said slowly:

"Can I borrow a tall ladder? The folding ladder we had in our car was not high enough. ”

When Zhang Chunbo heard this, he ignited his fighting spirit again, and turned around to arrange for someone to borrow, after all, every household in the countryside basically has such a ladder, because even if it is a ridged house, many people like to dry some things on the Chaoyang side.

Not to mention the flat-topped ones, they like to sit on the flat-topped roofs when drying all kinds of dried fish, dried radish, and even sewing quilts.

After a while, two ladders were borrowed, and Zhou Ning and Da Zhao gave them instructions, and in pairs, they began to observe the wall, especially the section of the wall with footprints.

Da Zhao went out, climbed the wall from the outside, observed the position above the footprints, the camera clicked continuously, moved twice, Da Zhao waved his hand at Zhou Ning, although he didn't shout excitedly, but his expression already said everything.

"Zhou Xiaozhou, the glass inserted in the wall here, there are traces of fragmentation, not one or two pieces, you see about a meter, there is no sharp glass ballast, and there is no broken glass inside and outside the wall."

Zhou Ning glanced at the location, it was about a meter away from the location of the footprints, and there was hardened ground below, but how could he go back if he jumped down so high?

Could it be that you climbed over the wall and prepared two ladders?

Zhou Ning waved his hand at Yang Xuetong and Sun Gaotie, motioning for them to carry the ladder over.

"Send the ladder to Da Zhao outside the courtyard and see if a single person can put the ladder in from the outside and complete it alone."

The two carried the ladder and ran out quickly, the ladder was bamboo, the height was about 3.5, and the weight was not heavy, but the bamboo had a problem, that is, it creaked, and the sound of the two of them was not small.

Zhou Ning stood by the wall in the courtyard, Da Zhao had already heard what they said, understood what Zhou Ning was going to do, and quickly collected samples from the glass fracture surface at the head of the wall, and then threw the camera and test tube to Zhu Xingxing below.

At this time, Yang Xuetong and them had already reached the foot of the ladder, Da Zhao climbed down a little, took the ladder, and swayed towards it.

Holding the edge of the ladder with one hand to control the balance, and carrying the ladder with the other, the ping-pong kept making a collision sound, and when he reached the wall, he didn't wait for the ladder to be completely put over, and the ladder fell off as soon as his hand was sliding, and it fell outside.

"Stop, even if it's an aluminum alloy ladder, I searched it, the four-meter bamboo ladder is also 9.4 kilograms, carry it up with one hand, and then open it, the sound will not be small, the deceased female sleep is not as heavy as the male, and there is no air conditioning in summer, open the door and open the window, this sound is enough to wake up."

Da Zhao nodded, climbed down quickly, and several people returned to the courtyard, and they were also in trouble for a while.

"There is no trace of entry and exit in the small window, and it is far-fetched to climb in on the wall, so how did the murderer get in?"

Da Zhao's question, Zhou Ning couldn't answer it, he shook his head slightly.

"If you don't understand, then don't think about this first, and carefully investigate the upstairs and downstairs in the room, didn't the villagers reflect that the Wang family was originally the landlord of Jiaotuan Village, and also compensated for the gold bars, since there is this rumor, then check it out to see if there are traces of the deceased's house turning, calling Bai Forensic Medicine."

Da Zhao nodded, he knew what Zhou Ning meant, and asked the white forensic doctor to follow, if they left traces of the police, they could avoid repeating the survey and sampling.

The four of them scattered, and directly called Forensic Doctor Bai upstairs, and Xu Dayuan came over.

"I called someone from the village committee, you come and listen."

Zhou Ning followed Xu Dayuan and came to the outside of the courtyard.

The people of the village committee kept nodding to Xu Dayuan, but no one dared to come up and take the initiative to shake hands, after all, Xu Dayuan looked a little too serious with a dark face.

"After investigation, we listened to the villagers' reactions, after the policy reform that year, Hai'an City compensated the Wang family, saying that it was to return the gold bars confiscated by the Wang family that year, and we want to verify whether there is indeed such a thing?"

The village chief nodded.

"Our old director said before that he compensated Wang Hongzhan's parents back then, and according to the records in the archives, a lot of gold bars and silver dollars were confiscated in the original courtyard of the Wang family, and in the past seven years, seven or eight gold bars were returned to the Wang family, but I really don't know how many gold bars there are, I only know about it."

Previously, Zhang Chunbo and their investigation did not find gold bars, and according to this result, it was enough to turn the nature of the case to money.

Zhou Ning leaned over and asked:

"He Dongmei's list of people who make up classes in the village, do you have it here?"

The village director glanced at Zhang Chunbo, and then nodded.

"Zhang Da asked before, and we also counted it, some of them followed for a few days, and some of them came from Teacher He, and we followed the lecture to the day before the accident, and we made statistics."

As he spoke, the village director pushed the man beside him, and the man quickly took out a list and handed it to Xu Dayuan.

Xu Dayuan glanced at it, there were indeed a lot of names, and handed them directly to Zhou Ning, Zhang Chunbo continued:

"We investigated the above people one by one according to the list, most of them were children under the age of ten, only three children were 12-16 years old, very thin, not small, that is, Wang Guangliang, Jiao Tinglong, Li Zhenxue.

These three people are not too far from the deceased's home, we carefully checked the size of their footprints and shoe prints, and after comparing them with the footprints left at the scene, we found that they did not match, and the surrounding neighbors did not see them go out at night. ”

Zhou Ning went through the list, and indeed according to the above statistics, the maximum shoe size of these people was 40 sizes, which was far from the results of the on-site investigation.

"Director of the permanent population of the village, you should have a list, such as the families of these make-up children, as well as the surrounding neighbors, I want the contact information and identity information of all the men, and whether anyone has gone out to work after August last year?"

Such a question made the village director stunned.

"Wait a minute, I need to go to the village committee to adjust the foundation, I have the names of the people in the village on my mobile phone, but not all of them do not have a phone, such as those who are over fifty-five years old, and they have a phone and a landline, or they are PHS."

After waiting for a while, the clerk brought a large book, which registered all the villagers' information, Zhou Ning called Xiaoqu and a person from the local technical department, these are all handwritten contents, it takes some time to identify them one by one, or do they need to sort it out.

Zhou Ning continued to ask:

"Again, the question just now, after last August, did anyone go out to work? Or if you used to work outside the home, but came back last summer, do you have an impression of such a person? ”

The director of Jiaotuan Village recalled for a while, and seemed to have lost the sense of panic just now, so he said slowly:

"In this way, there is indeed one, Jiao Dazhuang was originally in the south, but at the end of May and early June, he broke his leg and came back to recuperate for two months, and he was scolded by his daughter-in-law for being a waste, and he left in a hurry in mid-August, and the calculation date was on the third day after Wang Hongzhan's accident."

Zhou Ning glanced at Xiaoqu, Xiaoqu hurriedly found Jiao Dazhuang's information, and checked the information found on the police pass.

"Jiao Dazhuang is 33 years old, graduated from junior high school, engaged in the weak current parts processing industry in Jiangsu and Zhejiang Province, worked in Zotye Electric Appliance Group for seven years, his wife Zhu Xiaohui is 34 years old, farming, and his eldest son Jiao Renyou is 10 years old, studying in the third grade of Malan Town Primary School, and He Dongmei has him in the list of supplementary classes."

"Anyone else?"

The village chief shook his head.

"Let's put it this way, there are many people in our Jiaotuan Village, and those who have not come back after the test have settled down in the city, just like Wang Hongzhan, those who are not good at ability are also away all the year round, and rarely come back in the middle, there are almost no strong laborers in the village who are twenty to forty years old, and the work in the fields is done by old people and women."

Xu Dayuan leaned over and waved his hand directly at Zhang Chunbo.

"Bring Jiao Dazhuang's daughter-in-law, Zhu Xiaohui, over and ask."
