Chapter 156 KPMG

Jiang Yuan and Wen Ming met in the parking lot. Before getting in the car, they both looked confused.

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

"We are investigating a case." Jiang Yuan said.

"Then the specific content of our investigation is shopping?"

"Hmm..."

Wen Ming sighed, "I used to hook up with my girlfriend this way..."

Jiang Yuan and Wen Ming reconfirmed their eyes before saying, "Then find another person?"

"Three men shopping?" Wen Ming's expression was almost uncivilized.

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

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

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

Wen Ming was stunned, and then his whole body stiffened: "You actually asked the master's daughter to go shopping with you?"

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

Wen Ming shook his head stupidly. Male police officers usually don't get to know female police officers.

The ones that male police officers can get to know are all female men.

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

There was an Astro Boy with iron arms in front of the T-shirt, not very serious. The khaki shorts were knee-length, and the style was very casual, but the exposed calves were white and thin.

"Senior sister." Wen Ming looked a little embarrassed, but he got out of the car and opened the door actively.

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 going to buy anything?" Wei Yin looked generous and looked at Jiang Yuan again, and said: "I heard that you were in danger yesterday. Are you okay?"

"Maybe you scared yourself." Jiang Yuan was a little embarrassed.

According to the model that Master Wu Jun said, as a policeman, you have to make judgments constantly, and there will always be times when you guess wrong.

Don't feel embarrassed if you guess wrong. Many times, except for you, everyone else has forgotten your previous judgment.

Jiang Yuan thought that what Master said made sense 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?"

"Just look for sneakers." Jiang Yuan said while driving, but his expression was a little more serious when it came to the case.

Wei Yin saw it and asked, "Is it needed to solve the case?"

She had also seen the case of footprints solving the case.

Jiang Yuan only said "yes", and then said, "I can't tell you the specific situation."

"I understand, just say what you can say." Wei Yin smiled and said, "If you say a little more details, we can narrow the scope of investigation."

"Just look for sneakers first. When we get there, I want to look at the soles of all their shoes."

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

Wen Ming interrupted, "Do you want to check it online?"

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

The suspect's age, as determined by Jiang Yuan from the footprints, is 45 to 49 years old, and if extended by two years, it is 43 to 51 years old. But this is the safe age set by Jiang Yuan, and it can be basically determined that the suspect's real age must be within this range.

But from a more radical perspective, Jiang Yuan is more inclined to believe that the suspect is older.

Because judging age by footprints is also affected by the suspect's muscle ability. From the point of view of the suspect returning to the crime scene, Jiang Yuan believes that his muscle ability should be stronger.

Because people's confidence is undoubtedly affected by their physical condition.

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

While the three were talking, the Land Cruiser arrived at the commercial street of the county town.

Wei Yin naturally became the leader, leading Jiang Yuan and Wen Ming in big strides, from Nike to Adidas, from Peak to Hongxing Erke...

In the store, Jiang Yuan did not do anything, but asked the two and the clerk to take out various shoes and turn them over to check the soles one by one.

In order to check the soles conveniently, Jiang Yuan would buy two pairs of shoes after entering the store.

Soon, the three of them had their hands full of shoes.

"If you can't find it again, it's time to change the shoes for everyone in the team." Wei Yin thought it was a little funny.

Wen Ming was also a little anxious, and said, "I heard that there seems to be a database of shoe sole patterns."

"Yes, you can look up shoe samples through the shoe sole patterns." Jiang Yuan nodded and said, "But there are about 600,000 kinds of shoe sole patterns in the country every year, and only a small part of them are entered into the database. Even for big brand sports shoes, they may not be entered."

Wen Ming was stunned: "Are there so many?"

"There are more than 100,000 formal and informal shoe factories in the country." Jiang Yuan said, "It is impossible to exclude those small workshops."

Many of the suspects who are still committing violent crimes are people with two lows and one high, that is, low income, low education and high age. And these people will not run to specialty stores all day long to wear shoes.

Speaking of which, people from an era when violent crimes were common a few years ago are still willing to commit violent crimes. The new generation of young people, when involved in crime, are more willing to commit non-contact crimes such as telecommunications fraud.

Serial rape stories that once appeared frequently are becoming less and less common after the new century.

Wen Ming was silent for a moment and then asked: "If it is not entered, how can I check it?"

"Just like now, if you don't find it, you won't be able to find the person through the shoe sample." Jiang Yuan told the truth.

Footprint evidence is actually the trace evidence with the largest amount of physical evidence management in China, and the number has already exceeded fingerprint evidence.

But when it comes to database management, footprint evidence is too weak.

Wen Ming sighed helplessly. He was originally looking forward to breaking through again.

Jiang Yuan and Wei Yin looked at each other and smiled. Things like breaking the eucalyptus would not always be smooth sailing.

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

Nowadays, a store that can keep people in the store is definitely doing a booming business. There were several waves of people shopping in this store, which immediately attracted Jiang Yuan and others.

When I got closer, I saw a large number of clothes, pants and shoes in a small store.

There are also sports shoes, which are basically in black, white and gray colors, and then dark blue, which is in line with the aesthetics of middle-aged and elderly people.

Jiang Yuan saw no one to greet him and was not polite, so he turned over his shoes by himself.

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

The pattern on the bottom completely matches the shoe prints Jiang Yuan extracted from the scene.

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

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

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

The clerk frowned: "There are so many people here every day, how can I remember to come here?"

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

"There is another one that has gone to the warehouse." The clerk was busy doing the checkout and then asked, "What do you do?"

Wen Ming looked at Jiang Yuan with inquiring eyes at this time. When Jiang Yuan nodded, he walked closer and said, "Call that clerk back."

As he spoke, he showed his police officer ID.

When the clerk saw it was a police officer, he was first panicked, then overjoyed, and asked, "Can I take a photo?"

Wen Ming frowned and said, "You can take pictures. You need to call your colleagues over first."

"Okay, okay." The clerk agreed and asked again: "Did she commit a crime? What did she do? I'll just say that this girl is full of tea. She must have gotten into trouble..."

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

"Just...here." The clerk pointed to the cashier.

"The last day you sold these shoes, do you remember?" Jiang Yuan confirmed that the monitoring was stored on the hard drive of the host computer, and then asked.

The clerk looked at the KPMG shoes and said, "Then I have to check the account?"

"Check it." Jiang Yuan stood and watched.

The clerk said from the cashierbr/>The sales of this store are very good. They can sell dozens or hundreds of items every day. It is considered the best store in the neighborhood.

The clerk flipped through the pages quickly, pointed with his hand, and said, "I sold one the day before yesterday. It comes with clothes, pants, and socks. It's quite rare to buy a complete set..."

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

"Well, my colleague sells it." The clerk replied.

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

The clerk's colleague was a little prettier and better dressed. After flipping through the monitor on the computer, he suddenly slapped his forehead and recalled: "He was sitting at the door and asked me to bring him some shoes. No. walk in."

"What did he use to pay?" Wei Yin asked helpfully.

"Cash, I remember, this guy is quite weird." The pretty clerk smiled pleasantly.

Jiang Yuan and Wen Ming looked at each other and felt that something was funny.

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

"I wasn't wearing it... maybe. I don't remember where I touched it." The pretty shop assistant tilted her head in embarrassment.

The ordinary store clerk gave her a disdainful look and said, "You are not allowed to hold a stool or anything when trying on shoes."

"Then I don't remember. How many people sit on this stool every day?" the pretty clerk replied rudely.

Jiang Yuan looked at the small red square stool at the door and knew that nothing could be wiped out.

but……

"There should be surveillance in the mall." Wen Ming thought of it without Jiang Yuan reminding him.
