Bai Song has really never been to a bank to retrieve anything. In Li's case, he has seen bank transactions, so he understands the situation. He also knows that it is indeed possible to work for a long time and get nothing, but once the idea comes out,

Lingering.

In the end, Bai Song got through to Wang Xu and reported the idea to Wei Suo together.

In fact, the work of the case handling team has been reduced a lot recently. Most of what the case office can do is basic work, and there is no progress despite dozens of records. Therefore, Wei Office agreed to Bai Song's request and divided it into two groups.

Start querying bank transactions of specific people.

It was almost two o'clock at noon when the video was retrieved. Wang Xu asked Bai Song to have some authentic mutton soup. The two of them changed into their casual clothes in the car and went to a mutton soup restaurant.

According to Wang Xu, this store has a history of more than 40 years. Wang Xu’s master drank mutton soup here when he was a child, and it is very authentic.

Ten yuan for a big bowl, soup, sesame sauce, spicy food as you like, sesame seed cakes for 80 cents each, assorted vegetarian dishes, braised beef head, authentic halal way to eat.

After taking a sip of the sesame-colored hot soup with a hint of red oil, most of the coldness of the day was dispelled.

Bai Song stirred the mutton soup with a spoon, and the rich soup stirred into a small vortex. "Brother Xu, tell me, is it possible that these two people didn't run away at all?"

"Didn't run away?" Wang Xu didn't understand.

"We have ruled out many, many possibilities. Can you understand it this way? These two people had other residences in the Daguangli community. When they finished killing people, they went to the bungalow opposite to throw away some masks and other things and exchange them for

Put on clothes, and then returned to their residence in Daguangli Community, waiting for the police to complete their investigation before coming out?" Bai Song said: "As long as they don't leave this bungalow and Daguangli Community, the surveillance video will basically not be able to capture them.

, compared to the fact that there are no cameras between the two places.”

"Hmm... That's possible when you say that." Wang Xu said thoughtfully: "Avoiding surveillance videos is now a basic skill for criminal suspects. There are so many movies now... The cameras in our police station are far behind. If they are like those at the Sanlin Road Police Station

Enough."

"Then we will go to the site later?" Bai Song asked.

"Okay." Wang Xu nodded.

After eating, the two returned to the vicinity of Daguangli Community and walked to the door of the house where Sun died. The door was still locked, and it was obvious that no one had been here these days.

"First of all, judging from the traces on the roof, the suspect entered the house from the roof and the method of killing was poisoning. Preliminary analysis shows that the suspect first hid and then waited for the victim to smell and drink cyanide-containing

The hydrogen water appeared later, and then they had a quarrel with the victim. Later, the victim was poisoned and fell to the ground. The two opened the door and ran away, taking away the container." Wang Xu said that this is the most reasonable explanation at present.

"Well, there are a few questions," Wang Xu analyzed to himself: "The first is that there are no signs of fighting at the scene, but there are signs of quarrel. Logically speaking, Sun should know these two people; second,

That is, if they came down from upstairs, where is the fixed point? And how to remove the rope?"

"Is there such a possibility?" Bai Song said: "In fact, only one of these two people knows Sun, and we don't know. In fact, there was only one person who entered this house, and he was probably short.

The taller one actually didn't come in. He used his body to hold the rope on the roof. He waited for the shorter one to successfully commit the crime, then packed up his things and left together."

"Huh?" Wang Xu said: "This can explain the problem of the rope upstairs. Then, why do the people upstairs wait for the person downstairs to go with him after he succeeds? If he stays on the roof for too long, he is not afraid.

Has it been discovered?"

"Very few people go up to this kind of floor. If the person downstairs succeeds faster, it's not impossible."

"As you said," at least one of these two people must know Sun, and be relatively familiar with him. Otherwise, if someone suddenly enters someone's home, even if they are friends, they will probably start a fight.

?" Wang Xu said.

"If you say so, familiarity is not enough. You have to be a relative or friend. Suppose you are at home one day and you don't open the door. Suddenly you see me at your house. It will scare you to death, right?

Right? You can probably beat me out..." Bai Song complained.

"There are indeed many doubts here. Let's go downstairs." Wang Xu said.

"Well, let's recreate the crime scene. After the two of us went downstairs, the neighbor had already opened the door and saw Sun falling on the ground. At this time, you and I had already gone downstairs and walked out together. Then the neighbor reacted

Come here, look out the window, and you will see us walking out."

Bai Song stood in the open space in Daguangli and looked up at the window on the sixth floor. There are many trees in this old community. It is not easy to see the people below from the sixth floor. This is what happened on the tenth floor.

In February, if it's June or July, the trees are so leafy that you can't even see the people downstairs.

"The time we came down is only a minute and a half. The only place where the neighbors can see us is this area." Bai Song gestured to a small area around him. As he walked further, he left the field of vision, and behind and on both sides,

It was difficult to see from the sixth floor. You had to stick your head out to see it. But my neighbor didn't stick out his head and saw it directly from the top.

"Based on the analysis of DNA, height, footprints, etc., the two suspects match the physical condition of the two people identified by the neighbors. We assume that these two people are murderers. Then, walking from the building to here is not easy.

That's right." Bai Song gestured: "The entrance to this unit door, if you want to go to the bungalow opposite, you don't need to go this way, just go straight. Since you didn't go straight, but turned right first and walked here, then

It means that as soon as they came out, they did not rush to the bungalow to change clothes."

"Maybe they are not familiar with this area?" Wang Xu retorted.

"If they were people who came to collect debts, killed someone in passion, and stabbed Sun to death, I believe what you said, but these two people acted carefully and planned before they took action. The surveillance around them must have been studied in advance. How could they not be familiar with them?

?”

"Well, that makes sense." Wang Xu nodded: "If you say that, does it mean that these two people did not go to the bungalow immediately?"

"No, they must have gone to the bungalow, and they must have changed clothes there. I asked Zheng Yanwu, and the time period he mentioned was very close to the time when the murder occurred, so these two people should be the first
