Hello, Miss Ann!

"Horizontal cut marks, forensic identification is done by knife tools!" Bai Chun said that he handed a piece of information to the table top and motioned for Xiao Yao to take a look. Xiao Yao quickly played a group of videos. According to the video, Bai Chun went on to say, "but there is a kind of murder weapon, fish silk thread, that can cause horizontal cutting marks."

"Fish thread?" There are questions.

"The fatal injury is undoubtedly suffocation caused by throat puncture, but the wound where the victim's limbs were separated is most likely caused by fish thread." Pointing to the scene of the crime, Bai Chun pointed to the murder weapon he was looking for near the crime scene. He continued, "we found the murder weapon near the crime scene, but after identification, it was found that the thickness of the blade was not consistent with the thickness of the wound on the limbs of the deceased. Obviously, the thickness of the wound of the deceased was relatively thin and narrow! When the police searched near the crime scene again, they found that area C on the third floor of 215 building was a fishing business district! And in the C901 shop to find the fish thread with blood, DNA verification, the blood on the fish thread is the deceased's! "

Bai Chun goes to the whiteboard, looks at the whiteboard, is stunned for a while, he starts to write.

1、 The murderer is about 30-40 years old, male;

2. Businessman, or engaged in trade procurement;

3. Good at computer, once engaged in related occupation;

4

At the fourth point, Bai Chun stops writing.

Bai Chun said, "building 215 is a trade building! 215 building, the eighth floor is the computer mall! The police have investigated some special circumstances of the victim Ke Xin. Every month, he comes to the 215 building computer shopping mall to buy computer equipment, but he basically won't do it, because the equipment he chooses is rare or expensive. For some businesses in the computer mall, the expensive equipment is imported, which is not only difficult to import, but also has a lot of taxes, unless ordered Otherwise, they will not purchase any goods! For computer mall buyers, such as Kexin technology house is the best, but also the most troublesome guests! Kexin once bought a set of projection equipment in b892 shop of computer mall, worth 1 million yuan! This news spread all over the computer mall, many businesses know that there is a guest Ke Xin! Therefore, it may also be the reason why the prisoner targeted Kexin. "

"Boss, do you mean that criminals kill for money?" Xiao Yao asked.

"This is the first possibility!" Bai Chun said.

After hearing this, they were all puzzled.

Bai Chun continued, "the projection equipment ordered in b892 shop is not ordered by Kexin! It's another buyer, but the buyer has been unable to contact after the deposit, until now the business can not contact this buyer

"Is that the second possibility?" Xiao Yao suddenly suddenly suddenly, he said excitedly, "because the thing that you like is robbed by people, and you have hatred, so you kill people?"

"But didn't you look into the buyer's information?" Bai Chun said.

Xiao Yao thought for a moment, nodded and said, "the buyer is a student. It seems that he has made a lot of money by doing live broadcasting. He originally wanted to buy a set of Nissan's projection equipment, upgrade the configuration and carry out the live broadcast! As a result, he didn't want to buy the Live Broadcasting website because of its poor income! He looked for a business to refund the deposit, but the merchant refused to return the deposit on the ground that he had purchased goods. He had to swallow his anger! Results after a while, the projection equipment of the b892 shop was bought by Kexin! After the merchant has made a sum of money, he doesn't want to return the deposit. If the student doesn't come to recover it, it's over! "

Xiao Yao continued to think, continued to say, "in this case, the second possibility is not tenable, right? Who killed Kexin

"It's not only the student and Kexin, but also other people who are interested in the projection equipment." Bai Chun said.

"Others?" Xiao Yao was puzzled.

Obviously everyone doubts.

Bai Chun went to another white board, pointed to the third floor of 215 building, and said in a voice, "that man is here."

……

Come to the shopping mall on the third floor of 215 building to buy fishery supplies.

The trade building is the trade building. No matter where it is, there are lots of people.

Bai Chun and Xiao Yao go to the shop where the murder weapon was found. The shop has been closed. Then the flow of people around here is obviously less than that of others. Until they get to a corner, the flow of people is even less.

"What do you want to buy, boss? All the fishing rods in our shop are imported! "

"Boss, come in and have a look! There are many special items for you to choose from

"Boss, have a look, have a look!"

……

Many businesses are peddling, seemingly lively, but there is no one.

"Oh! Inductive cameras? " Xiao Yao saw a shop in the corner of the door, actually with the most advanced induction camera, this camera can be based on human body heat to track observation, for ordinary businesses, this kind of thing is not cheap.

"Go in and have a look!" Bai Chun opens his voice.

They walked into the store. The door was automatic, and there was a voice welcome mode. Although it was not a novelty, for other stores, this one was a bit of high-tech."What can I do for you, boss?" The mechanical sound came.

On the shelf near the door, there is a small robot, shaking its head and waving its hands according to its speed.

"Boss, there are guests, come out to entertain the guests!"

"Would you like something to drink? We have water and tea here

……

Standing in the middle of the shop, the shop is very big, but it seems a little crowded. There are five robots, large and small, in different corners of the shop.

It seems that the whole shop is operated by robots.

"No, no, no That's good. I, I, I I just Just eating Eat. "

A stammering man came out of the cubicle, a little plump, and his face looked a little surprised at the presence of guests, but soon there was a welcome smile on his face.

"Please Excuse me, boss, you What do you want to buy what? My shop All imported fishing rods All of them, Bao Guarantee that Certified product

After listening to the man struggling to finish speaking, the robot behind him also began to sound.

"Guest, I'm sorry! We boss don't speak well. It's rude! Can you tell us what you need! We are very enthusiastic to serve you! "

"Guest, do you want us to introduce you?"

"Guest, would you like tea or water?"

……

He said, "look at the boss's silent face, it's a sharp look from his eyes. It's a sharp look on the boss's face."

"Yes, yes Yes Xie Feng answered.
