Bai Song hasn’t really gone to the bank to retrieve anything. In Li’s case, he has seen the bank’s flow. So he understands this situation. He also knows that this job is indeed likely to be busy for a long time and get nothing, but once this idea comes out, Lingering.

　　 In the end, Bai Song still made sense of Wang Xu and reported this idea to Wei Suo together.

In fact, the recent work of the case-handling team has decreased a lot. Most of the work done in this case is basic work, and dozens of records have been recorded and no progress has been made. Therefore, Wei Suo agreed to Bai Song’s request and divided two people into it. Begin to inquire about the bank transactions of some specific personnel.

　　 It was almost two o’clock at noon that the video was transferred. Wang Xu said that he would invite Bai Song to drink the authentic lamb soup. The two changed into the plain clothes in the car and went to a lamb soup restaurant.

　　 According to Wang Xu, this shop has a history of more than forty years. Wang Xu’s master drank lamb soup here when he was young, and it was very authentic.

　　 A large bowl of ten yuan, add any soup, sesame sauce, and spicy pepper, eight cents a biscuits, assorted vegetables, beef stew, authentic halal way of eating.

　　 I drank a sip of the hot soup with a little red oil in the sesame sauce, and the cold for a long time dissipated most of it.

　　 Bai Song stirred the lamb soup with a spoon, and the rich soup whirled in a small whirlpool under the stirring of the spoon, "Brother Xu, is it possible that these two people didn't run away at all?"

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

"We have eliminated many, many impossibility, can we understand this. These two people have other residences in Daguangli Community. When they finished killing, they went to the opposite bungalow and threw away some masks and other things. After getting on the clothes, they went back to their residences in Daguangli community, waiting for the police to complete their investigations before they came out?" Bai Song said, "As long as you don’t leave this bungalow and Daguangli community, surveillance video will basically not catch them. , Compare there is no camera between these two places."

"Well... it's possible for you to say that." Wang Xu thoughtfully: "Avoiding surveillance video is now the basic skill of criminal suspects. Now there are so many movies... Our cameras are far behind, if it's like the Sanlin Road Police Station. Enough."

　　 "Then we two will go to the scene again later?" Bai Song asked.

　　 "Good." Wang Xu nodded.

　　 After eating, the two returned to the neighborhood of Daguangli Community and walked to the door of the house where Sun Mou died. The door was still locked here, and they knew 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. The method of killing was poisoning. According to preliminary analysis, the suspect first hid it, and then waited until the victim smelled it and drank it containing cyanide. The hydrogen water only appeared later, and then quarreled with the victim. Later, the victim fell to the ground after being poisoned. The two opened the door to escape and took away the container." Wang Xu said, this is the most reasonable explanation so far.

"Well, there are a few problems," Wang Xu analyzed to himself: "The first is that there are no signs of fighting at the scene, but there are signs of noisy. It is reasonable to say that Sun should know these two people; second; That is, if they came downstairs, where is the fixed point? How did they take 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 it. In fact, there is only one person who entered this house, and it is very likely that he is short. That, the tall one didn't actually come in. He grabbed the rope with his body on the top of the building. Waiting for the short man to succeed in the crime, he packed up his things and left together."

"Huh?" Wang Xu said: "This can explain the rope problem upstairs, so why should the people upstairs wait for the downstairs to get their hands on walking with him? If he stays on the roof for too long, don't be afraid Was it found?"

　　 "This kind of floor, few people go up, if the person downstairs succeeds faster, it is not impossible."

"That's what you said." Of these two people, at least one of them must know Sun Mou, and it's a relatively familiar one. Otherwise, someone will suddenly enter the house, even if it's a friend, maybe they will have to fight. ? "Wang Xu said.

"If you say that, it's not enough to be familiar with this level. You have to be relatives and friends. You can suppose that one day you are at home and you did not open the door. Suddenly you saw me appear at your house, and it scared you to death. Right? You can beat me out..." Bai Song vomited.

　　 "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 like this, the neighbor had opened the door and saw that Sun had fallen to the ground. At this time, you and I had already gone downstairs and walked out together, and the neighbor reacted. Come here and look out from the window, just in time to see the two of us walking out."

Bai Song stood on the open space in Daguangli and looked up at the window on the sixth floor~lightnovelpub.net~ 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 in December. If it was in June and July, the trees were so luxuriant that there would be no people downstairs in sight.

　　 "The time we got down is one and a half minutes. The only place where the neighbors can see us is this area." Bai Song gestured to a small area around it. Going further forward, I left the field of vision, and the back and both sides are hard to see from the sixth floor. You have to stick your head out, but the neighbor didn't stick out his head and saw it directly upstairs.

"Analyzed from DNA, height, footprints, etc., the two criminal suspects fit the physical conditions of the two people identified by the neighbors. We assume that these two are murderers. Then, walking here from the building, That’s right.” Bai Song gestured: “At the door of this unit, if you want to go to the bungalow opposite, you don’t need to go here, just go straight. Since you don’t go straight, you just turn right and walk here. Then It shows that as soon as they came out, they were not in a hurry to go to the bungalow to change their clothes."

　　 "Maybe they are not familiar with this neighborhood, right?" Wang Xu retorted.

"If it is someone who comes to collect debts, kills people passionately, stabbed Sun Mou to death, I believe what you said, but these two people acted carefully, planned and moved later, and the surrounding surveillance estimated that they had studied in advance, so how could they be unfamiliar? ?"

　　 "Well, it makes sense," Wang Xu nodded: "If you say that, it means that these two did not go to the bungalow the first time?"

"No, they must have gone to the bungalow, and they must have changed their clothes there. I asked Zheng Yanwu, the time period he said was very close to the time when the murder happened, so these two people should be the first I changed my clothes in no time." Bai Song said, "I have an inference."
