After many investigations, we have more and more clues, and they are becoming more and more complicated. It seems that every clue is inseparable from the case, but it seems that every clue has not brought any breakthrough value to the case.

So much so that every clue we have must carefully analyze the role of this clue in this case, as well as all the possibilities brought by this clue.

When we analyze and discuss all the possibilities of this clue and reject it, we can completely abandon this clue.

Because of this, the workload is very high, and there are so many things to think about.

The most troublesome thing for us is that because of the uncertainty of the clues, we found a lot of contradictory situations between the clues when we analyzed and discussed, and the incomplete consideration of the possibilities made us dare not easily let go of any hard-won clues.

It's like right now—

Ren Qiushi passed the autopsy and said that the murderer and Shan Jinfeng had the deepest hatred.

Jiang Tingbai passed the trace examination and said that the murderer's shoes were size 36 and he was wearing slippers, and there was no situation where big feet wore small shoes and small feet wore big shoes.

Li Meng wrote through the foul profile, saying that the murderer's age was between fifteen and twenty years old, and the family had been changed to join the single family, but the single family hated this murderer who came to join the family.

Also, the eleven-year-old Guo Jialu, who had a conflict with Shan Jinfeng, is a 36-yard foot.

Also, Guo Jialu's father, Guo Dahao, is deliberately hiding some things from us.

These clues are contradictory, first of all, Ren Qiushi's autopsy, we investigated that the person who had a conflict with Shan Jinfeng was Guo Jialu, a classmate, but could Guo Jialu really complete the murder of seven people in a row alone?

If Guo Jialu's father Guo Dahao is guiding him to commit crimes, what hatred does Guo Dahao have with the Shan family?

According to Li Meng's criminal profile, we conducted an investigation through the relatives of the single family, and no suspects who matched the image of the criminal profile appeared.

In addition, Shan Jinfeng suffers from aplastic anemia, is this case related to his disease?

Perhaps, we really missed some key clues.

Or, we haven't found this most crucial clue yet.

This analysis and discussion of the facts of the case has not reached any substantive results, and what we need to do now is to deal with the single reports that are still coming to find a single declaration of debts.

He is still locked up in the detention room of the criminal police team, Lin Zifan went to investigate the situation of the Qingju Inn that he confessed, if the situation is true, then he has a sufficient alibi, this murder case has nothing to do with him, and he can be released.

As for Guo Dahao, Guo Jialu's father and son, we still have to investigate him, even if their family has nothing to do with this Chinese New Year's Eve murder case, they must have done other illegal and criminal things.

Today is the first day of the Lunar New Year, and 24 hours have passed since the incident, and in just 24 hours, we have investigated the hospital where Shan Jinfeng was treated, Shan Jinfeng's teacher Yin Meng, Shan Jinfeng's classmate Guo Jialu, and Shan Bao, who had an economic dispute with Shan Xuan.

After a while, Officer Wang and his criminal police officers also returned to the criminal police team.

They went out for a day today to investigate the cake shop where Shan Xuan and Qin Jing worked respectively, and at the same time conducted a social relationship survey on the three elderly people of the Shan family.

However, because today is the first day of the Lunar New Year, which is a special time, and the employees are returning to their hometowns for the New Year, their investigation work is not comprehensive, but they are doing their best.

Now that it was dark outside, I asked the other members of the serious crime team to go back to rest first, and I went to the criminal police team myself to communicate with them about the clues from this investigation.

In the office of the criminal police team, everyone was full of exhaustion, Officer Wang calmed down, cheered up and said: "We have mainly conducted an investigation today on the work units of Shan Xuan and Qin Jing, and we have conducted a social relationship investigation on the three elderly people of the Shan family. ”

After everyone briefly reported their work, then Officer Wang said a problem he found today: "Through the investigation of Shan Xuan and Qin Jing's work units, we found that Shan Xuan and Qin Jing have been asking their colleagues about borrowing money in the past month, and they seem to be raising money for their eldest son Shan Jinfeng's bone marrow transplant. ”

Hearing this, I was suddenly stunned, because Li Meng and I went to the First People's Hospital of Ningzhou City, where Shan Jinfeng was treated, and also met Qin Yidan, Shan Jinfeng's attending physician. But Qin Yidan didn't say that he found a bone marrow match for Shan Jinfeng? Did they find a bone marrow match through other sources? But where did they find the bone marrow match where they didn't even have a high degree of matching with their biological parents?

The cost of a bone marrow transplant is generally divided into preoperative, intraoperative, and postoperative.

The preoperative costs are the cost of examinations and medicines, as well as the cost of surgery.

The intraoperative cost is the cost of a bone marrow transplant, which is lower if a relative provides hematopoietic stem cells, and higher if it is provided by a volunteer or bone marrow bank.

The postoperative cost is the cost of recovery, and in addition to regular check-ups and medications, corresponding rehabilitation training and nutritional supplements are required.

The cost of a bone marrow transplant ranges from tens of thousands to hundreds of thousands, and the difference lies in the source of the bone marrow.

Since Shan Xuan and Qin Jing are already raising money for their son's surgery, it means that they must have found a suitable bone marrow match.

"So will this person who provided hematopoietic stem cells have anything to do with this case?" I pondered for a moment, then suddenly muttered.

"Team Qin, what did you say?" As he spoke, Officer Wang suddenly stopped and turned to me.

I was stunned for a moment, but I hurriedly came back to my senses and said, "It's nothing, you go on." ”

"Oh." Officer Wang looked at me in some surprise, and then said to everyone, "Go on, what else did the teams find?" ”

"Through the investigation of the capital flow of a single family, we found that they have had a large number of consumption records in the past month, ranging from a few thousand yuan to tens of thousands of yuan each time, and they have purchased health care drugs and nutritional products." A criminal policeman said in a deep voice.

After hearing this, Officer Wang nodded thoughtfully: "There are elderly people and sick people at home, so it's not strange to buy health care medicine and nutritional products......

"It's really not strange to buy health pills and nutritional products at home, but it's very strange to give these things to anyone......" I frowned and said lightly.

"Team Qin, did you think of something?" When Officer Wang heard me speak again, he felt that something was wrong and hurriedly asked me.

"Perhaps, the single family has found a bone marrow matching ...... privately"
