Chapter 217

"What, you said the man who poisoned the cow had been to my house!" Tian cuie was surprised.

Zhao Yusheng also came over and squatted down to check the shoe prints. At the same time, he took out his mobile phone and compared it with the shoe prints left by the suspect on the mobile phone.

"Oh, it's just like the shoe prints left by the suspect."

Zhao Yusheng can't help but take a look at Han Binggao. There are no bricks in the yard. It's all dirt roads. There are a lot of messy shoe prints. It's hard for ordinary people to distinguish the suspect's shoe prints from the chaotic ones.

"Isn't the suspect poisoned in the grass? How can he come to my house?" Tian cuie looked worried and asked Zhao Yusheng: "director Zhao, the suspect doesn't want to harm my family."

"Don't be nervous. Maybe the shoes are the same. You may not be a suspect." Zhao Yusheng comforted.

"People have different body structures and different walking postures. Even if they wear the same shoes, the footprints will be different. I'm sure the footprints are left by the suspects." Han Bin is right.

"What can I do? Do you put back my family's old money? What can I do if the suspect harms me again? I can't fight him as a woman." Tian cui'e took the opportunity to say.

"Don't worry. Remember, who has been to your house these days?" Han Bin asked.

Tian cui'e shook her head and sighed, "ah, my cattle have been poisoned. People in the village have heard about it. Many people have come to watch the excitement. I was also worried that day. I can't remember the chaos."

"It seems that acquaintances are very likely to commit crimes." Li Hui guessed.

"When you think of a person, write down a person in a notebook, especially a middle-aged man about 40 years old, who is about 175cm tall." Han Bin said.

"You mean the man who poisoned my cattle is a man about 40 years old and 175 cm tall." Tian cuie asked.

"It's not absolute, but it's very possible." Han Bin said.

Tian cuie doubts a way: "how do you know?"

"I know a little bit about footprint identification."

"Just by looking at the shoe prints? It's amazing. You can tell how old you are by the shoe print. " Tian cuie is a little incredible.

"Different people's age, the way of walking will also change, according to the foot shape, stride characteristics, gait characteristics of comprehensive analysis, including step angle, step width, step length, foot weight; indentation, lift marks, pedal marks, tread marks, dig marks, after a series of analysis, data comparison, we can get the approximate age of the suspect." Han Bin explained.

However, people are still at a loss.

Li Hui, who had seen Han Bin's skill in footprint identification, was very confident of him and said with a smile, "since our group leader said that he is a middle-aged man about 40 years old, he must not be wrong."

"Team leader Han, could you explain it briefly? I'm a little confused." After all, Zhao Yusheng is a deputy director, and has no blind obedience.

Clues to solve the case are all about evidence. It's the first time he and Han Bin meet. It's impossible for him to believe what the other party says.

If other people ask, Han Bin may not explain, but Zhao Yusheng is different. Han Bin is a stranger here and needs the other party's assistance in handling the case.

"The simplest way to judge is the indentation method, which is closely related to gender, age, height and posture. The younger the age, the more forward the pressure surface of the forefoot; the older the age, the more backward the pressure surface of the forefoot, and move outward." Han Bin said, pointing to the ground:

"the heavy pressure of the forefoot of this shoe print is outward and backward; the indentation is lighter in the front, heavier in the back, lighter in the inside and more emphasis on the outside; the indentation area of the heel is large; the pick and scratch are obvious. According to my experience, it's about 40 years old."

"I see." Zhao Yusheng still did not understand, however, or casually echoed a sentence.

Seeing that Han Bin said so professionally, he also believed 70% to 80%. Moreover, he was an old police officer after all, and his position was higher than Han Bin's. He continued to ask questions, but he didn't have any light on his face.

"Director Zhao, if you can release my family's old money, I have no bottom at home." Tian cuie said.

"Don't even think about good things. The criminal cases committed by your family's old money will not come out for a while. If you are really afraid, you will go to live with your relatives for a few days and come back after the case is solved." Zhao Yusheng snorted.

"When can you solve the case?"

"When the case is solved, you will be informed." Zhao Yusheng said perfunctorily.

He is not an immortal, nor is he able to calculate. How can he tell the exact time.

"Officer, you're from the city. You can say something for me. It's not easy for my family to get rich. We can't spare him this time. Are we willing to pay more Tian cuie said to Han Bin.

"It's a good idea for you to contact the victims of food poisoning in the city. As long as you can get their understanding and take the initiative to make compensation, you can help Qian Jinfeng reduce his sentence to a certain extent when the court decides." Han Bin said.

"I don't know any victims. Can I give you the money? Please say something for me." Tian cuie said.Han Bin laughed and declined politely, saying, "I'm only responsible for handling cases, and I don't care about anything else."

Han Bin's family is not poor in money and has a bright future. How can he make such a low-level mistake.

"How long does my family have to keep the money?" Tian cuie asked.

"It's up to the court how long the sentence will be, and we can't answer you."

Li Hui frowned and urged: "you'd better cooperate with our investigation. If you catch the suspect early, maybe you can get some compensation."

"Compensation?"

Tian cui'e's face showed a touch of joy, and quickly asked, "can you really compensate my family if you catch the poison cow criminal? How much can I give you? "

"Don't say you're fat, you'll be panting. Let's catch the suspect of poison cow first." Zhao Yusheng waved his hand and said impatiently:

"it's important to cooperate with these comrades to take notes."

Later, a group of people entered the room. Li Hui and sun Xiaopeng took notes for Tian cuie.

Tian cuie is in her forties. She is good at farming, but she can't use a smartphone and has no opinion. Many of her answers are ambiguous. After asking for a long time, she has no new clues.

However, I recalled a few people who came to her home. There were eight names of men and women. This was only part of it, and there were still some things I didn't remember.

Some of these people came to comfort her relatives and friends, and more of them came to see the busy people.

In Tian cui'e's words, some villagers who don't travel much are willing to come to her house for a walk when they hear that something has happened to her family. They are just like greedy cats who smell the fishy smell. They say a few words of concern, but they are gloating in their hearts.

……

After recording, they returned to Xizhang town police station.

"Team leader Han, where did you learn to identify your footprints? It's good enough." Zhao Yusheng is curious.

"I've specially looked for some relevant materials. I like to ponder over them when I have nothing to do. I have some experience." Han Bin said perfunctorily.

"No wonder you can be the head of the criminal police force at a young age." Zhao Yusheng praised.

"You flatter me." Han Bin answered, and the conversation changed:

"director Zhao, since the suspect has been to Qian Jinfeng's home, he may be an acquaintance or even a villager in the village. I think we can further narrow the scope of investigation."

"What do you suggest?" Zhao Yusheng asked.

"The state has banned the sale of tetramine. You can check the source of its sale and radiate it around Zhangcun village in Northwest China." Han Bin suggested.

Han Bin is not familiar with beixizhang village, which is more convenient for the local police station to investigate.

"No problem. I'll arrange it when I get back to the Institute." Zhao Yusheng nodded.

Beixizhang village is not far from Xizhang town. It's a short drive.

Han Bin returns to the temporary office and finds that Zhao Ming and Tian Li have come back.

Han Bin did not care about the rest, open-minded way: "how is your investigation?"

"We found Zhang Lei's feed store, but he went out to purchase, not in the store." Tian Li Road.

Li Hui poured a glass of water and gently sat down on the chair: "this boy is not afraid of crime to abscond."

"We visited the surrounding people again. According to them, Zhang Lei is really about 40 years old, but he is not tall, and he is only about 1.7 meters tall." Tian Li said.

"Brother bin, Zhang Lei's height is not quite consistent with your judgment, so we feel that his suspicion has dropped a lot." Zhao Ming shrugged.

"When will he be back?" Han Bin asked.

"We called and he said he would be back tomorrow morning." Tian Li said.

"Go again tomorrow morning, and be sure to see him." Han Bin knocked his right index finger on the table and continued:

"most people's height and footprints are in line with a certain proportion, but this is not absolute. Some people are born with big or small feet, so footprint identification can only be used as the basis of investigation, not as conclusive evidence."

The more cases he has experienced, the more cautious Han Bin is. Some common sense inferences may make the case fall into the wrong area. Nothing is absolute.

That's the same thing. The evidence will prevail.
