Chapter 157: KPMG

Jiang Yuan and Wen Ming met in the parking lot. When they got in the car, their expressions were a bit confused.

"Are we going shopping together?" Wen Ming asked: "It's a bit strange."

"We are handling the case." Jiang Yuan said.

"Then the specific content of our case handling is shopping?"

"Hmm..."

Wen Ming sighed: "I used to pick up girlfriends like this..."

Jiang Yuan and Wen Ming reconfirmed their eyes before saying: "Then find someone else?"

"Three men shopping?" Wen Ming's expression was about to become uncivilized.

"Mu Zhiyang's arm is still hanging with a plaster, count him as half, that's two and a half..." Jiang Yuan paused and started sending WeChat.

"Are you calling Mu Zhiyang?" Wen Ming's face was full of disgust. Two and a half men shopping, how could it be worse than two men shopping.

"I'm calling Wei Yin." Jiang Yuan put down his phone.

Wen Ming was stunned, then his whole body stiffened: "You actually called Master's daughter to accompany you shopping?"

"Do you know any other female police officers?" Jiang Yuan asked back.

Wen Ming shook his head foolishly. Where can male police officers come into contact with female police officers?

What male police officers can come into contact with are all tomboys.

After a while, Wei Yin appeared in front of the two wearing a white T-shirt.

The front of the T-shirt is an Astro Boy, looking not very serious. The khaki shorts are knee-length, the style is very casual, but the exposed calves are white and thin.

"Senior Sister." Wen Ming looked a bit embarrassed, but actively opened the car door.

Jiang Yuan sat in the driver's seat, turned around and handed Wei Yin a bottle of water, and smiled: "Sorry, we don't want to go shopping together."

"Are you buying something?" Wei Yin looked generous, and looked at Jiang Yuan again, saying: "I heard you encountered danger yesterday, are you okay?"

"Maybe I scared myself." Jiang Yuan was a little embarrassed.

According to the mode said by Master Wu Jun, as a police officer, making judgments all the time, there will always be times when you guess wrong.

If you guess wrong, don't feel embarrassed. Many times, except for yourself remembering your previous judgment, everyone else has forgotten.

Jiang Yuan felt that what his master said was very reasonable before, but now it seems that someone still remembers something.

Wei Yin chuckled, looked at the time again, and said: "I can only accompany you for two hours, where do you want to go shopping?"

"Just look for sneakers." Jiang Yuan said while driving, only involving the case, his expression was slightly serious.

Wei Yin saw it and asked: "Is it needed for solving the case?"

She has also seen footprint solving cases.

Jiang Yuan only said "Hmm," and then said: "I can't say the specific situation."

"I understand, just say what you can say." Wei Yin smiled and said: "You explain a little more detailed, so we can narrow the investigation range."

"Just look for sneakers first. When we arrive, I want to see the soles of all their shoes."

"This requirement... is actually not low." Wei Yin nodded.

Wen Ming interjected: "Do you want to look online."

"Look again later. If you can't find it in the store, look online." Jiang Yuan explained: "Judging from the suspect's age, he should be more accustomed to buying things in the store."

The age of the criminal suspect Jiang Yuan judged from the footprints is 45 to 49 years old, and then expanded by two years, which is 43 to 51 years old. But this is the safe age range Jiang Yuan delineated, basically determining the real age of the criminal suspect, which must be within this range.

But judging from a more radical perspective, Jiang Yuan is more inclined to the suspect's age being older.

Because judging age by footprints is also affected by the suspect's muscle ability. Judging from the fact that the criminal suspect returned to the crime scene, Jiang Yuan believes that his muscle ability should be relatively strong.

Because a person's confidence is undoubtedly affected by their physical state.

A physically weak criminal suspect, or even a middle-aged man with ordinary physical fitness, will not easily make the decision to return to the crime scene.

The three of them arrived at the commercial street of the county town while talking.

Wei Yin naturally became the leader, striding with Jiang Yuan and Wen Ming, from Nike to Adidas, from Peak to Hongxing Erke...

In the store, Jiang Yuan didn't do it himself, just let the two and the clerk take out various shoes and look at the soles one by one.

And in order to facilitate the inspection of the soles, Jiang Yuan bought two pairs of shoes directly after entering the store.

Soon, the three of them were full of shoes in their hands.

"If you can't find it again, you should change shoes for everyone in the team." Wei Yin found it a bit funny.

Wen Ming was also a bit anxious and said: "I heard that the pattern of the sole seems to have a database."

"Hmm, query the shoe style by sole pattern." Jiang Yuan nodded and said: "But every year in the country, there are about 600,000 kinds of sole patterns. Very few are recorded in the database. Even big-brand sneakers are not necessarily recorded."

Wen Ming was stunned: "There are so many?"

"There are more than 100,000 regular and irregular shoe factories in the country." Jiang Yuan said: "It is impossible to exclude those small workshop factories."

Criminal suspects who are still committing violent crimes now are many in the two-low-one-high population, that is, low income, low education, and high age. And these people wear shoes and will not go to specialty stores all day long.

Speaking of which, it is the people in the era when violent crimes were frequent in previous years who are still willing to commit violent crimes now. And the new generation of young people, when participating in crimes, are more willing to commit non-contact crimes such as telecommunications fraud.

Serial rape cases that often appeared in the past have also been heard less and less since the new century.

Wen Ming was silent for a while before asking: "If it's not recorded, how to check?"

"Just look for it like this now. If you can't find it, there is no way to find the person through the shoe style." Jiang Yuan said the truth.

Footprint evidence is actually the trace evidence with the largest management volume in the country, and the quantity has long exceeded fingerprint evidence.

But in terms of database management, footprint evidence is too weak.

Wen Ming sighed helplessly. He was originally looking forward to solving another serious case.

Jiang Yuan and Wei Yin smiled at each other. Solving cases is never smooth sailing.

"There are quite a few people over there, many of them are elderly, right?" Wei Yin pointed to the front, which was a discount store.

Nowadays, a store that can keep people coming is absolutely prosperous. There are still several waves of people shopping in this store, which immediately attracted Jiang Yuan and others.

Approaching, I saw a small store with a lot of clothes, pants, and shoes.

There are also sneakers, basically black, white, and gray color schemes, and then dark blue, which meets the aesthetics of middle-aged and elderly people.

Jiang Yuan saw that no one greeted him, so he didn't be polite and turned the shoes himself.

After turning seven or eight pairs, a pair of gray and white sneakers fell into Jiang Yuan's hands.

The pattern at the bottom is completely consistent with the shoe print Jiang Yuan extracted from the scene.

Jiang Yuan looked at the brand calmly: Bi·Mawei.

It feels quite foreign, but it feels like it shouldn't be a shoe factory that needs auditing very much.

"Has anyone bought this pair of shoes before?" Jiang Yuan asked this question because he suddenly thought that the shoe style at the crime scene was very new, and this brand was so unfamiliar...

The clerk frowned: "There are so many people every day, how can I remember."

"Are you the only one in the store?" Jiang Yuan continued to ask.

"There is another one who went to the warehouse." The clerk was busy checking out, and asked again: "What are you doing?"

Wen Ming looked at Jiang Yuan with inquiring eyes, and seeing Jiang Yuan nod, he walked closer and said: "You call that clerk back."

Saying that, he showed his police officer ID.

The clerk was panicked when he saw it was the police, then happy, and asked: "Can I take a picture?"

Wen Ming frowned and said: "You can take a picture, you call your colleague over first."

"Alright, alright." The clerk responded and asked again: "Did she commit a crime? What did she do? I said this girl is tea-like, did she get involved in a case..."

"Where is your store's surveillance video?" Jiang Yuan interrupted the clerk's narrative.

"Just... here." The clerk pointed to the checkout counter.

"Do you remember which day you sold this shoe last time?" Jiang Yuan confirmed that the surveillance was on the hard drive of the host, and then continued to ask.

The clerk took out a notebook from under the checkout counter and turned it quickly.

The sales of this store are quite good, and dozens or hundreds of things can be sold every day, which is considered the best store in the vicinity.

The clerk turned it quickly, pointed with his hand, and said: "I sold one the day before yesterday, with clothes, pants, and socks. It's rare to buy a whole set..."

"You didn't sell it?" Jiang Yuan asked.

"Hmm, my colleague sold it." The clerk answered.

Jiang Yuan waited patiently for the clerk's colleague to come back, asked similar questions, and asked her to point out the person on the surveillance video.

The clerk's colleague looked a little prettier, dressed more beautifully, turned the surveillance on the computer for a while, and then slapped her forehead, recalling: "He was sitting at the door at that time, let me take the shoes for him. Didn't walk in."

"What did he pay with?" Wei Yin helped ask.

"Cash, I remember, this person is quite strange." The pretty clerk smiled beautifully.

Jiang Yuan and Wen Ming looked at each other and felt that there was a play.

Jiang Yuan asked first: "Did he touch anything? Did he wear gloves?"

"Didn't... right, touched where, I don't remember." The pretty clerk tilted her head embarrassedly.

The ordinary clerk looked at her with disdain and said: "Try shoes, you have to support the stool or something."

"Then I don't remember. How many people sit on this stool every day." The pretty clerk retorted unceremoniously.

Jiang Yuan looked at the red small square stool at the door, knowing that he couldn't wipe anything out.

However...

"The mall should have surveillance." Wen Ming didn't need Jiang Yuan to remind him, and had already thought of it. ===== CHAPTER 158 =====

But...

"There should still be surveillance in the shopping mall." Wen Ming didn't need Jiang Yuan to remind him; he had already thought of it.
