Not only Du Dayong and the others are working hard on this case, the Dongjiao police are also expanding the scope of investigation and collecting biological samples from more qualified men.
Because after testing, the suspect has blood type B, so those who do not meet the conditions are basically screened out immediately.
For three days in a row, Du Dayong and his team members followed the experiments in the rental house and conducted reverse searches on the street, and found three relevant people who had fragments of memories in their memories.
A person who was working the night shift passed by the victim and seemed to hear the sound of yelling, but it was not obvious. He thought the couple were quarreling and did not pay attention, but from the sense of perception, he felt that both men and women seemed to be together.
Not a local accent.
The other two also got off work at ten o'clock. They were not far from where the victim worked, but lived very close to each other. However, after investigation, they found that their blood types were not type B.
However, according to the recollections of the two people, the victim did ride back alone and did not find anyone following him. After the victim turned to the row of rental houses, the two people did not find any suspicious people appearing.
Du Dayong and his team members were also in trouble at this time and had to hold a small meeting after finishing their work on the third day.
Now there are differences of opinion among the team members, and Du Dayong feels it is necessary to discuss it.
It is assumed that acquaintances are supported in committing the crime. However, the victim's circle is very small, there are too few acquaintances, and the blood type of the suspect basically does not match. The only two people with the same blood type did not commit the crime.
Through the retrieval of the victim's call records, basically except for calls from her hometown of Liaocheng, there were almost no outgoing calls. It was also not found that any classmates or friends of the victim had recently come to Dongjiao to visit her.
However, if it is supported that the victim was followed or followed into the house by a stranger, and suddenly the stranger entered the house at around 22:30, as long as the victim calls, there are still many people working nearby, and the suspect should
He would not brave the world's disapproval and forcefully break into the room at such a time. After the victim was not tied up, he not only stayed there for so long, but also used the victim's mobile phone to send messages to her boss. This is obviously inconsistent with the case.
Discover the logic of the scene.
So what is the relationship between this criminal suspect and the victim?
Could it be that the victim had not known the criminal suspect for a long time, and the victim was not too defensive about the criminal suspect? Could it be that the victim had just begun to fall in love with a male friend that no one knows yet?
"Captain Du, what I learned last time is that the victim sends money home once every three months, so the amount of money left in the rental house is not quite right. There is a difference of at least four hundred!"
Fu Cheng's words made Du Da's brain explode.
"I felt like something was wrong. You were right to remind me that if the money had just been sent not long ago, then the amount of money left at the scene was obviously not correct."
"Then the criminal suspect must have either embezzled money or sexually assaulted him. Is the extra 400 yuan compensated by the criminal suspect to the victim? Then the victim was dissatisfied and felt that the compensation was less, and then the criminal suspect became angry.
He killed the victim out of shame!"
Tang Wei suddenly became excited after Du Dayong's words.
However, Du Dayong felt it was inappropriate because it did not fit the victim's personality, but he did not say it out loud, mainly because he was afraid of damaging Tang Wei's confidence in speaking out.
But before it was his turn to strike, Li Xiaohui started to spray.
"Nonsense! This is impossible! No matter whether we have obtained the information or visited the victim in person, the victim did not appear to be in a greedy state. The victim even brought back some toilet paper and soap from the restaurant and talked to Liu Zongxiang or Song Chunfeng about it.
I just brought it back."
Tang Wei was so retorted by Li Xiaohui that she didn't know what to say.
Du Dayong could only come out to smooth things over at this time.
"The case was discussed in a calmer manner. No matter who speaks, it is to contribute to the investigation. Although Tang Wei's opinion is very unlikely, it cannot be denied that it is possible."
"Our No. 1 Squadron is a collective. As the acting captain, I will not make any remarks. If there is anything that needs to be argued, let's not be in a hurry. It's not a life-and-death feud."
Li Xiaohui knew that Du Dayong was criticizing her tactfully, and she couldn't hold back her tears immediately.
Du Dayong's scalp is also numb. Can't he just talk properly? He sheds tears every now and then. What does that mean?
At this time Yunxiang spoke.
"Why are you crying? Wipe your tears. You are a criminal police officer, and you are also a criminal police officer in the special case team. You can't stand any criticism? Then what kind of criminal police officer are you? If you still want to do legal matters, don't report it yourself.
, I finally got into the squadron, but I can’t accept this criticism? Did Captain Du make a mistake somewhere?”
"Tang Wei is just a trainee police officer here, what about you? You are her senior sister and a role model for her to learn from! When people put forward opinions, can you say that others are talking nonsense? Without our help and guidance, how can they grow up slowly?
"
"Captain Du is a young captain, and he is also our leader. I criticize you tactfully because you are a girl, but I think here, first of all, you are a detective, and secondly, you are a girl. Do you understand?
?”
Li Xiaohui took a few deep breaths, wiped away her tears, and quickly stood at attention and saluted.
"Tang Wei, I apologize for what I just said. I shouldn't have spoken so hastily! I'm sorry!"
"It's okay! Senior Sister Xiaohui, I didn't even take it to heart. I know everyone is anxious now and I can understand your mood."
Du Dayong clapped his hands at this time, signaling for everyone to be quiet.
"To make a long story short, these are all minor details. I will go to the site tomorrow. Fu Cheng will be with me. The rest of us will continue to figure it out. We must start with the details this time, especially the origin of the four hundred yuan.
, is it left by the criminal suspect? I will work overtime with Wei, Lu Yi, and Jiang He later to compare all the banknotes carefully to see if we can find any new clues."
"Li Xiaohui and Tang Wei will specifically interview the victim's female colleagues tomorrow to see if they can discover any undiscovered details."
"Master Peng, tomorrow we will lead Shuai Shuai, Luo Xin, Shen Rui, and Chi Yu to continue the visit. We still need to look for clues among the people working the night shift in Zhengjiazhuang."
"Master Yun is still sitting in the team, summarizing the situation of all parties, so that it can be easily inquired when the case analysis meeting is held later."
"It's okay now. Take the time to rest. The second round of inspections, inspections and visits will begin tomorrow morning. The meeting is adjourned!"
Du Da waved his big hand and immediately ended the small meeting.
