Chapter 284 The drowned child in the pickle jar

An hour later, the car arrived in Hai'an City.

On the way, Xu Dayuan had received several calls and reported the details of the two cases in Rudong City to Bureau Hu. Of course, at the end, Xu Dayuan told him about Fat Master.

Director Hu was silent for a long time and agreed to Xu Dayuan's arrangement and placed the case on the last itinerary of the working group.

As soon as the car stopped, there were many people standing in front of the car door. You can tell that this was the leaders of the Hai'an Municipal Bureau. Such enthusiastic treatment was really a big difference compared to Rudong City.

The captain of the criminal police team was Zhang Chunbo, who seemed to be very familiar with Xu Dayuan. The two chatted for a few words and then greeted everyone. Xu Dayuan said a few simple words, with only one purpose. They came here to clean up the backlog of cases. The first job was to persuade everyone to leave.

Zhou Ning and the others followed Xu Dayuan and then went to a conference room. As soon as they came in, they found that there were people sitting inside. Zhang Chunbo grinned and said:

"Don't be surprised, we have been waiting for you to come. Last night, I asked someone to stay at Rudong Municipal Bureau. I have the first-hand information on your investigation progress. Seeing that the matter was over there, I think I should be able to come today, so I might as well get everyone here and let's analyze the case?"

Looking at Zhang Chunbo with a passionate face, Xu Dayuan was also a little helpless.

"Why are you so anxious? Oh, can't we take a break when we come?"

Zhang Chunbo waved his hand, looking indifferent.

"What are you resting? After investigating these cases, isn't it nice to go back to my home to rest? What does it mean? When I arrived in Rudong, it was said that the construction started that day. Why did I have the money here?"

Xu Dayuan smiled, punched Zhang Chunbo and sat directly in the middle. Zhang Chunbo introduced the names of the personnel in their team. Xu Dayuan looked at the file in front of him and paused.

"The backlog of cases you have filed are not two, why are there three files here?"

Zhang Chunbo grinned.

"Don't be excited, the backlog of cases is indeed two. The other is a case we are investigating now. The identity of the deceased has not been found. I heard that you brought Director Zhou here, so I think I might as well take it out and help us determine it together so that we can also have an investigation direction.

After all, the identity of the deceased needs to be found out, and even if 80% of the investigation of this case is clear, why don’t we look at the two cases from many years ago first?”

Xu Dayuan glanced at Zhou Ning, saw that he didn't say anything, and nodded at Zhang Chunbo.

"Let me introduce the case."

Zhang Chunbo opened the notebook and said hurriedly:

"The first was the family-killing case in 2011. The case occurred in Jiaotong Village, Baishahe Street. Early in the morning of August 14, the Jiaotong Village clerk reported the case. People died in Wang Hongzhan's family in Jiaotong Village. Our criminal police team arrived at the scene at 8:22.

After being investigated by the forensic doctor Bai Hua, he found that there was a deceased in the middle of the yard, Wang Hongzhan's wife He Dongmei. She lies prone to the ground with a knife in her back, piercing her heart.

After evidence collection and testing, no DNA from a second person other than He Dongmei was found on the knife, and there were only fingerprints of a thread glove on it. The inside of the yard was sealed, and the gate was locked from the inside. There was a ten-centimeter hole in the gate, which was used to unlock and tying the door.

As for all windows, there are guardrails and no one can enter or exit. The only one without guardrails is the kitchen window, but adults cannot pass through. We guess the murderer is a thin adult or a tall and thin teenager.

After investigation, it was found that the deceased He Dongmei was at home with her two-year-old son Wang Jiahan. Wang Hongzhan worked in Shenzhen market all year round and came back for more than ten days every year during the Chinese New Year. He heard that his wife and children were killed, so he rushed back.

We began to search for the courtyard of Wang Hongzhan's house. Under the eaves on the west side of the main house, we found a pickle jar pressing on stones. We opened the body of Wang Hongzhan's son Wang Jiahan.

The child was curled up and stuffed into the pickle jar with his head facing down, and had drowned. The time of death was the same as He Dongmei, between 22:00 and 23:00 on August 14.

The pickle jar was 45 cm in diameter and 45 cm in height. The neighbors said that this was used by the Wang family to make pickle, but after the old man of the Wang family passed away, he never used it again. He Dongmei was born on May 22, 1980. She is a teacher at Hai'an No. 6 Primary School. She is humble and has no grudges with others.

Usually, He Dongmei lives in the city with her children. The parents of the Wang family live in this old house. After the old couple died in a car accident in 2009, they did not come back. However, in July last year, they notified that they would survey and map and let the family keep people. He Dongmei came back with her children and helped the children in the village to make up for free.

After visiting, we found two statements, saying that Wang Hongzhan might have offended people and left Hai'an City. However, our investigation found that Wang Hongzhan is a very powerful person in IT and is preparing to buy a house in Shenzhen and move his family over, but he didn't expect that this happened.

There was also an old man who said that the Wang family's parents died suddenly and did not leave anything at all. However, the Wang family was once the largest landlord in Jiaodan Village. All the land in this village belonged to their family. After the rumor was reported, the land was not given to them, but the debts for the house searches were returned that year, as if they were given a lot of gold bars.

However, we thoroughly searched the Wang family's old house many times, but we did not find the hidden gold bars or any effective clues. We just found two footprints in front and back beside the flowers on the west wall. At that time, we compared them with the villagers and found no same sole prints.

One of the footprints is very complete, and the bottom is still mud. We brought them back to keep samples. As for the old house of Wang Hongzhan, Wang Hongzhan left the key. No one has been there for us this year. We have also investigated Wang Hongzhan himself. He has a good relationship with his wife. He is a classmate in junior high school and does not have an affair."

"Did the deceased's mobile phone remain at the scene, the last call record on it, and are there any clues on the text message?"

Zhang Chunbo nodded.

"There are mobile phones, and the call records have been verified one by one. They are all colleagues and relatives, and there are no special contacts. We have contacted all the people who have called within a week and investigated the activity trajectory of the deceased's death time, and found no valuable information."

Xu Dayuan kept recording that the photos taken on the big screen were on-site investigations and the photos taken were very detailed. When the photos stopped on the footprint, Da Zhao raised his hand and shouted to stop.

A middle-aged woman who controlled the computer looked up at Da Zhao, and it was obvious that she was the local forensic Bai Hua.

A female forensic doctor who can carry the job of a county-level city by herself shows that her ability is definitely not inferior to Xu Guanhai in Rudong City. Moreover, the photos on the scene are so detailed that she is indeed doing her best.

Da Zhao stood up and gestured with his thumb and index finger.

"Can doctor Bai enlarge the picture? It's like footprints on the soles of the shoe. I want to see the soles of the shoe."

Bai Hua nodded and said while zooming in:

"We compared it. This is a sneaker. The shoe size is 43. The shoes were the spring style of that year. The price is very expensive, even if there is a discount in summer, it will cost 1,868 yuan.

Jiaotuan Village is not a surplus village. Those who can afford such shoes should be at least fashionable young people. We screened all the young people who entered and left Jiaotuan Village from August 13 to 14, but there was no consistent result."

Da Zhao was not panicked at all and nodded at Bai Hua with a smile.

"Forensic Bai did a very meticulous job. Captain Zhang just said that this piece of mud with footprints was brought back. I don't know where it was kept. Can you take a look?"

The questioning of Da Zhao caused Xu Dayuan to look at him sideways. Generally, Zhao Xinli is still very modest, unless he found something, and Zhou Ning did not move, obviously supporting Da Zhao's approach. Xu Dayuan also looked at the forensic Bai Hua.

She nodded.

"Wait for me to get it. To prevent air drying, this one is stored in a closed cover to maintain humidity."

After a moment, Bai Hua came back with a transparent plastic box and placed it in front of Da Zhao and the others. Zhou Ning touched her body. Sun Gaoti stood up and pointed downstairs. Zhou Ning shook his head slightly.

He was used to it and liked to use the LED magnifying glass to observe the details. However, since Da Zhao wanted to see it, he must have discovered it. Zhou Ning was not in a hurry. After waiting for a long time, everyone stared at Da Zhao's movements. Seeing that he was constantly calculating what was written on the paper, he stopped writing and said:

"Forensic Bai, I would like to ask if the spacing between the two footprints was measured during on-site investigation. Can you tell me the value?"

Bai Hua flipped it out.

"Step 97 cm."

Da Zhao calculated again before stopping.

"Based on the depth of the footprint in the soil, the size, shape, distribution position of the force point, stride, etc., I estimated the height and weight of the suspect who left the footprint. The suspect's weight was about 150 kilograms, and the height was estimated between 175-180.

It can be seen from the footprint that the suspect's feet are slightly larger than the shoes. At the edge of the shoe, the marks of pressing down are very heavy, especially at the thumb and metatarsal joints. I think the normal size of the murderer's feet is 44 sizes, with a thumb valgus of more than 20 degrees."

This analysis made Xu Da look at him subconsciously. Zhou Ning nodded solemnly, which recognized Da Zhao's judgment.

However, Bai Hua on the opposite side frowned slightly and subconsciously looked at the footprints in the transparent box again. The details were indeed as Da Zhao said, but she was indeed not good at this judgment.

“Is there a formula?”

Da Zhao nodded and handed Bai Hua the piece of paper he had just used to calculate. Bai Hua still frowned after reading it, obviously not agreeing with this method.

Zhou Ning knew this kind of gaze too well. He thought that Zhao Xinli was young and did not look convincing. He didn't have the Mediterranean hairstyle, nor was he over forty years old. Zhou Ning didn't care. He knew that Da Zhao wouldn't care.

In fact, this case is strange enough. I don’t live in the old house all year round. I only have more than a month back. I still tutor the children in the village every day and were killed overnight.

Especially when a child is drowned in a water tank, is he seeking revenge or seeking money?

This cannot be used as a fact based on the speculation of the villagers alone.

The deceased was stabbed toward the gate of the yard and was stabbed in the back of the center of the yard. In the photo, the deceased was wearing a cool nightgown, with no shoes on his feet and around his body. He was woken up in the middle of the night and wanted to escape, or went out to call for help, and was killed by a knife.

The inside of the courtyard gate was locked, and there was no sign of a lock prying. It seemed that they did not come in from the main entrance. It was probably because of this. The people from the Hai'an Criminal Police Brigade believed that the murderer came in from the small kitchen window.

Zhou Ning put away his thoughts, looked at Bai Hua, and said with a smile:

"This calculation formula was taught by my teacher Li Chengbin. If Dr. Bai is interested, he will ask Zhao Xinli to copy it to you. There are many related formulas."

When Bai Hua was obviously stunned when he heard Li Chengbin's name, he sat directly on the chair. Seeing that she didn't say anything else, Zhou Ning said:

"I wonder if the dead body has been preserved or has been dealt with?"
