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

Models are naturally there, but they don't have any utility as the machine itself, just a small thing of resin. In addition to the model, Boss Qian also gave a small bottle of abrasives and promised that this thing could be shopped around.

After getting the things and leaving the factory, Li Han boasted: "Okay, you kid has some ideas." ”

Back in the car, Li Han was a little impressed by Bai Song. Although it does not mean that this is a useful clue to the case, the investigation of this kind of non-sudden case is a process of trial and error.

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

Bai Song looked at those photos last night and checked a lot of information, and he didn't know if this situation was correct, but the two of them still returned to the unit first and reported the situation to their superiors.

The leaders of the task force attached great importance to this situation and directly arranged the experiment, and in just two hours, the preliminary results were obtained, and the results of the experiment were gratifying.

There is a high probability that the method of shredding the corpse in this case was done by a high-pressure waterjet cutting machine, and the cut marks are very similar to the cut marks of the waterjet, and the abrasives used are also closer.

This time the scope was narrowed down, after all, the high-pressure waterjet cutting machine and the grinding wheel cutting machine in Tianhua City are completely two orders of magnitude. The former can even be searched exhaustively.

On the afternoon of the experiment, other departments also came with gratifying information. The victim's identity was fully confirmed.

Bai Song also knows a little bit about the specific methods and methods, but it doesn't matter, the important thing is that after knowing the victim's information, the information network such as mobile phone, residence, and contact person will come out.

According to this information, it was only one noon that seven relevant persons who had contact with the deceased were criminally summoned to the Public Security Bureau for investigation.

A huge task force, with reasonable arrangements and unity, can open a large shadow for the advancement of almost every point.

When all the shadows disappear, it is time to solve the case.

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 called, 49 years old, the owner of a small gold shop named Wang Qianyi, with whom the deceased had been in contact.

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

Considering the financial situation of the deceased, the police had to make a possible financial killing.

Wang Qianyi is not the last person to have contact with Li, and through inquiries and visits, there are no contradictions and disputes between the two.

After the questioning of the seven people ended, the case file was integrated, and in the evening, Bai Song also had time to look at the file, but he didn't find anything.

All seven of them were put back in the afternoon, and there was no evidence at all.

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

On the afternoon of the third day, the case entered a temporary deadlock. In recent years, all the registered ultra-high pressure waterjet cutting machines have been carpet checked, and no suspicious clues have been found.

On weekends, the white pine has a day off. After six days of work this week, there was still no breakthrough, and everyone was very tired. The task force has only one day off a week, and those who have half a day off on Saturday have half a day off on Sunday.

In the evening, I made an appointment to have dinner with Sun Jie, Hua Dong and others, and during the day, Bai Song was fine, so he walked around.

"Swim and fitness, understand!" a familiar voice interrupted Bai Song's train of thought, as if he had returned to his college days.

"This handsome guy! We have a discount at the gym! Come on, come on, find out!" a man and a woman took a flyer and handed one to Bai Song.

Bai Song habitually took the leaflet from the girl's hand. It's a very young girl, it doesn't seem accurate to use the word young, Bai Song looks at her and is only seventeen or eighteen years old, with a single ponytail, bright eyes and bright teeth, looking forward to the flow, anyone who sees it will praise her, what a lovely girl!

This place is not far from the criminal police detachment, and it is not too far from the Jiuheqiao police station, Bai Song glanced at the flyer, this gym is not bad, the swimming pool is a standard small pool, 25 meters long, and other equipment including a half basketball court are available.

"Now you can enjoy the discount when you apply for a card, today is the last day of the event!" The little brother who handed out the flyer saw that Bai Song did not throw away the flyer, and hurriedly stepped forward to introduce.

Today is the last day? Bai Song didn't say it, he said in his heart, this gym activity, if you miss today, you can only wait until tomorrow!

Thinking that he has been busy recently, Bai Song has no plans to apply for a card, and he just has nothing to do.

"Yes, as long as you register a mobile phone number, you can experience our gym for free, you can try it now. The little beauty with a single ponytail said: "There is no charge for one experience." ”

Saying this, Bai Song was a little moved, after all, today is not too busy, try it first, if it is really good, it is not bad to come over to apply for a card in the future. Bai Song picked up the pen in the girl's hand and wrote his mobile phone number directly. I don't know if it's an illusion, Bai Song feels that the girl is actually a little familiar. But he was sure that he really hadn't seen this beautiful girl.

Bai Song has always been fond of sports since he was in school, and even these days, he will do some equipment-free sports in the house. When he entered the gym, Bai Song was in a good mood, because he didn't bring a change of clothes, he simply did a warm-up, did a few sets of strength training, and began to stretch.

When exercising, sometimes the mind is more agile, and Bai Song began to deduce the case on his own.

The first problem that is now recognized is the motive for committing the crime. Who is it that has such a great hatred for women and does such a cruel and inhumane thing?

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

Oh, and think about the dead themselves.

The deceased, Li, a native of Chacheng, Southern Xinjiang Province, has been in Tianhua City for four years, is 26 years old this year, and his place of residence is located in the jurisdiction of the Sanmu Street Police Station in Jiuhe District, which is a high-end residential area that has been rented for two years.
