"Well, do you have a model here? I'll take one back and ask my leader for permission." Li Han asked finally.

Of course there is a model, but the model has no utility of the machine itself, it is just a small resin thing. In addition to the model, Boss Qian also gave a small bottle of abrasive and guaranteed that this thing can be compared with other products.

After getting the things and leaving the factory, Li Han praised: "Okay, you have some ideas."

Back in the car, Li Han had a new respect for Bai Song. Although this did not mean that this was a useful clue to the case, the investigation of such non-sudden cases was a process of trial and error.

As long as a person is still a human being, he must abide by the laws of this world, whether it is the laws of physics or the laws of science, no one can violate them. Some people read a lot of detective novels and watch a lot of legal programs, thinking that they can try to plan some so-called perfect crimes, which is simply courting death.

Bai Song looked at those photos last night and checked a lot of information. He didn't know whether this situation was correct, but the two of them returned to the unit as soon as possible and reported the situation to their superiors.

The leader of the task force attached great importance to this situation and arranged an experiment directly. In just two hours, preliminary results were obtained, and the experimental results were encouraging.

The dismemberment in this case was most likely done by a high-pressure water jet cutting machine. The cut marks are very similar to those made by a water jet, and the abrasives used are also closer.

This narrowed the scope immediately. After all, the high-pressure water jet cutting machines and grinding wheel cutting machines in Tianhua City were completely two orders of magnitude. The former could even be found exhaustively.

On the afternoon when the experiment came out, other departments also received good news. The identity of the victim was completely confirmed.

Bai Song had a general idea of ​​the specific methods, but that was not important. What was important was that after knowing the victim's information, the network's mobile phone, address, contacts and other information would come out.

Based on this situation, in just one noon, seven people who had contact with the deceased were criminally summoned to the Public Security Bureau for investigation.

A large task force, with reasonable arrangements and united efforts, can clear up a large area of ​​shadows with almost every advancement.

When all the shadows disappear, that's when the case is solved.

In the afternoon, the dog team was sent out, and Bai Song and Li Han were responsible for questioning a relevant person.

The person summoned was the oldest of the seven people called. He was 49 years old and the owner of a small gold shop. His name was Wang Qianyi, and the deceased had had contact with him before.

Upon questioning, it was found that the deceased, Li, had gone to Wang Qianyi's store more than a month ago to order a piece of gold jewelry weighing 235 grams, and the cost alone was as high as more than 4,000 yuan. Because of this, Wang Qianyi also left Li's contact information.

Considering the financial situation of the deceased, the police had to make the decision that it might be murder for money.

Wang Qianyi was not the last person to have contact with Li. Through inquiries and visits, there was no conflict or dispute between the two.

After the questioning of the seven people was completed, the case files were integrated. In the evening, Bai Song had time to look through the files, but he didn't find anything.

All seven people were released in the afternoon without any evidence.

The next day, four more people were called in to take statements, and the situation was the same.

On the afternoon of the third day, the case temporarily reached a stalemate. In recent years, all registered ultra-high pressure water jet cutting machines have been thoroughly checked, and no suspicious clues have been found.

Bai Song took a day off on the weekend. After working six days this week, there was still no breakthrough and everyone was very tired. The task force only took one day off a week, half of the people took a day off on Saturday and the other half took a day off on Sunday.

He had an appointment to have dinner with Sun Jie, Huadong and others in the evening. Bai Song had nothing to do during the day, so he walked around.

"Learn about swimming and fitness!" The familiar voice interrupted Bai Song's thoughts, as if he was back in college.

"Handsome guy! Our gym has a discount! Come on, come and find out!" A man and a woman held flyers and handed one to Bai Song.

Bai Song took the flyer from the girl as usual. She was a very young girl. The word "young" didn't seem quite accurate. Bai Song thought she was only about 17 or 18 years old. She had a ponytail, bright eyes, white teeth, and a charming look. Anyone who saw her would praise her, "What a lovely girl!"

This place is not far from the Criminal Police Detachment and not too far from the Jiuheqiao Police Station. Bai Song took a look at the flyer. This gym is pretty good. The swimming pool is a standard small pool, 25 meters long, and other equipment includes half a basketball court.

"You can enjoy discounts if you sign up for a card now. Today is the last day of the promotion!" Seeing that Bai Song did not throw away the flyers, the guy handing out flyers hurried forward to introduce them.

Is today the last day? Bai Song didn't say it. He thought to himself, if I miss today's gym activities, I can only wait until tomorrow!

Considering that he has been quite busy recently, Bai Song had no plans to apply for a card. He just took a look at it when he had nothing to do.

"It's like this. As long as you register a mobile phone number, you can try it out in our gym for free. You can try it now." The little beauty with a ponytail said, "It's free to try it out once."

Bai Song was a little tempted. After all, he was not too busy today. He could try it first. If it was good, he could come back to apply for a card later. Bai Song took the pen from the girl and wrote down his mobile phone number. He didn't know if it was an illusion, but he felt that the girl looked familiar. But he was sure that he had never seen this beautiful girl before.

Bai Song has been fond of sports since he started school. Even in the past few days, he would do some exercises without equipment in the house. Entering the gym, Bai Song was in a good mood. Because he didn't bring any spare clothes, he simply warmed up, did a few sets of strength training, and then began to stretch.

When exercising, one's mind sometimes becomes sharper, and Bai Song began to deduce the case on his own.

The first question that is generally acknowledged is the motive for the crime. Who on earth could have such a deep hatred for the woman that he could do such a cruel thing?

Bai Song began to think about the situation of the eleven people who had been called to the unit in the past few days.

Oh, first consider the dead themselves.

The deceased, Mr. Li, was from Chacheng, southern Xinjiang Province. He had been in Tianhua City for four years and was 26 years old this year. He lived in the Sanmu Street Police Station in Jiuhe District, a high-end residential area that he rented and had lived in for two years.
