Although Zhou Ning is very thin, she is tall and has long arms, and this height is very uncomfortable. If she has a chair outside, she can still climb in, but her figure may be smaller than what she analyzed before.

Xu Dayuan looked at the bottom of the window. It was not a modern building and there were no cabinets, range hoods, etc. This window was actually the function of this smoke exhaust.

So the inner and outer frames of the window and the metal hook are all covered with thick black grease, some of which seem to be dripping down the next moment.

Xu Dayuan held his arms and stared at the window, and couldn't help but wonder, isn't this like someone crawling in?

"According to your analysis, people can indeed come in here, but if you want to get in from here, especially at this height, your hands must be covered with grease. In every corner of the scene, especially the weapons and the dead, have you seen grease? Or found 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 on-site investigation, no trace was left except for a half footprint left on the mud and a dagger on the deceased's body.

At this time, Da Zhao put his head under the window. Lao Yang held his head and took photos of all the oil on the left and right windows. Then Yang Xuetong sprayed lumino, but there was no fluorescence reaction around him.

Zhou Ning came over and looked down. All the oil was about to drip, there were traces of rafting, and some were covered with dandelions and various dust. They had never been scratched or even touched.

This is not something you can avoid just by trying to avoid it. Zhou Ning signaled everyone to retreat, raised his hand and rubbed it with the back of his hand on the left. A piece of black grease and dust were stuck on the gloves, and then the window was then left with traces.

Xu Dayuan looked serious and looked at Zhang Chunbo and said:

"This window is not where the murderer enters and leaves. It seems that the direction of the search is incorrect."

Zhang Chunbo and Bai Hua were both stunned. The result and judgment made them unacceptable. After all, this courtyard had been inspected many times, and only the person here was the most likely to come in, but now it was denied.

The key is that the evidence presented by the working group made them unable to refute, but in this way, how did the murderer come in?

Zhou Ning walked closer and said slowly:

"Can we borrow a relatively high ladder? The folding ladder we brought on our car is not high enough."

When Zhang Chunbo heard this, he became more determined and turned to arrange for someone to borrow. After all, every household in the countryside has such a ladder, because even for a house with a ridge, many people like to dry something on the sunrise side.

Not to mention the flat-topped ones, they like to sit on the roof with a flat-topped ones, dried fish, dried radish, and even sew quilts.

Soon, two ladders borrowed. Zhou Ning and Da Zhao and the others ordered them, and they started to observe the wall, especially the one with footprints.

Da Zhao went out, climbed up the wall from outside, and observed the position above the footprints. The camera kept clicking and moved twice. Da Zhao waved his hand at Zhou Ning. Although he didn't shout excitedly, his expression had already explained everything.

"The glass inserted in the walls here at Zhou Xiaozhou had broken marks, not one or two pieces. It looked like there was about one meter, but there was no sharp glass slag, and there was no broken glass inside and outside the wall."

Zhou Ning took a look at the location. It was about one meter away from the footprints, and there was a hardened ground below. But how can I go back after jumping down so high?

Did you prepare two ladders after climbing over the wall?

Zhou Ning waved his hands to Yang Xuetong and Sun Gaoti, signaling them to carry the ladder over.

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

The two carried the ladder and ran out quickly. The ladder belonged to bamboo, with a height of about 3.5, and the weight was not heavy. However, there was one problem with the bamboo, which was that it creaked and creaked. The sound of the two people shaking like this was quite loud.

Zhou Ning stood by the wall in the yard. Da Zhao had heard what they said and understood what Zhou Ning was going to do. He quickly collected samples of the glass fracture surfaces on the top of the wall, and then threw the camera and test tube to Zhu Xingxing below.

At this time, Yang Xue and they were carrying the ladder to their feet. Da Zhao climbed down a little, took the ladder, and swayed toward the top.

He grabbed the edge of the ladder with one hand to control the balance, and held the ladder with the other hand, making continuous collision sounds. When he reached the wall, he had not waited to completely let go of the ladder, but when the ladder fell, he fell outside. As for this movement, Zhou Ning waved his hand directly.

"Stop, even the aluminum alloy ladder, I searched it and found that the four-meter bamboo ladder had 9.4 kilograms. I carried it up with one hand and opened it. The sound would not be small. The deceased women's sleep is not as heavy as men. There is no air conditioner in summer. Opening the door and window, this sound is enough to wake up."

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

"There is no sign of entering and exiting the small window, and it is far-fetched to crawl in from the wall. So how did the murderer come in?"

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

"If you can't figure it out, then don't think about this for now. Just check the upstairs and downstairs of the room. The villagers have reported that the Wang family was originally a landlord in Jiaodan Village and also compensated the gold bars. Since there is this rumor, let's check it out to see if there are any signs of turning around in the deceased's house, and call Dr. Bai."

Da Zhao nodded. He knew what Zhou Ning meant and asked for Forensic Bai to follow him. If traces of police officers were left, they would avoid repeated surveys and sampling.

The four of them scattered and called for Forensic Doctor Bai to go upstairs. Xu Dayuan came over.

"I'll call the village committee members here, come and listen."

Zhou Ning followed Xu Dayuan to the outside of the yard.

The villagers' members kept nodding with Xu Dayuan and the others, and no one dared to come up and shake hands on their own initiative. 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, Hai'an City compensated the Wang family, saying that it had returned the gold bars that the Wang family had searched that year. We want to verify whether this is true?"

The village director nodded.

"Our old director said before that he had compensated Wang Hongzhan's parents. According to the records in the archives, a lot of gold bars and silver dollars were searched in the Wang family's original yard. In the past seven years, seven or eight gold bars were returned to the Wang family, but I really don't know how much the specific amount is, I only know this."

Previously, Zhang Chunbo and his team found no gold bars during their investigation. According to this result, it was enough to turn the nature of the case into making money.

Zhou Ning came over and asked:

"Do you have any of the people who have given the tutoring in the village?"

The village director glanced at Zhang Chunbo and nodded.

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

As he said that, 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 him and said, "There are indeed many names, and he handed them to Zhou Ning directly. Zhang Chunbo continued:

"We followed the list and investigated the people above one by one. Most of them were children under ten years old. There were only three kids between 12 and 16 years old. They were very thin and quite tall, namely Wang Guangliang, Jiao Tinglong and Li Zhenxue.

These three people are not too far from the deceased's house. We carefully checked their footprints and shoe prints. After comparing them with the footprints left on the scene, we found that they were inconsistent with each other. Moreover, the neighbors around us did not see them going out at night."

Zhou Ning browsed the list and according to the statistics above, the maximum shoe size of these people is 40, which is far from the results of the on-site investigation.

"The permanent residents of the director's village should have a list, such as the families of these children who make up for the lessons, as well as the neighbors around me. I want all the male contact information, identity information, and is there anyone who went 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 get some information. There are names of villagers on my mobile phone, but some of them don't have phone calls. For example, those over 55 years old, who have phone calls are also landlines, or Xiaolingtong."

After waiting for a while, the document brought a big notebook with all the villagers' information registered. Zhou Ning called Xiaoqu and a local technical department person. These were handwritten content. It took some time to identify them one by one, but they still needed to organize them.

Zhou Ning continued to ask:

"It's the question just now. After August last year, did anyone go out to work? Or was they originally working outside, but they came back last summer. Do you have any impression of such people?"

The director of Jiaodan Village recalled it, and seemed to have lost the panic he had just now, and then he said slowly:

"After saying that, 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. He was scolded by his wife for being a waste. He left in mid-August. The date was the third day after the accident between Wang Hongzhan's family."

Zhou Ning glanced at Xiaoqu, and Xiaoqu quickly found Jiao Dazhuang's information and compared the information found on the police channel.

"Jiao Dazhuang was 33 years old, graduated from junior high school, engaged in weak-voltage parts processing industry in Jiangsu and Zhejiang Province, worked in Zotye Electric Group for seven years, his wife Zhu Xiaohui was 34 years old, farming, and his eldest son Jiao Renyou was 10 years old. He was in the third grade of Malan Town Primary School. He Dongmei had him on the list of tutoring."

"Who else?"

The village director shook his head.

"Let me put it this way, our Jiaotuan Village has a lot of people and land, and those who have passed the exam have not returned, most of them settle down in the city. Just like Wang Hongzhan, they are not capable, and they are always away all year round. They rarely come back in the middle. There are almost no strong laborers in the village between 20 and 40 years old, and the work in the fields is done by the elderly and women."

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

"Take Jiao Dazhuang's wife Zhu Xiaohui here to ask."
