At noon on the fifth day of the first lunar month, the office of the head of the criminal investigation detachment of the Xuanhu City Police Bureau. Xue Yuanjian is waiting for Wang Yijun: Wang Zhi went to the DNA laboratory to get various physical evidence inspection reports of the "Ning Yuanfu Murder Case" in Tongxi County?

"Xue Zhi, the biological samples sent by Tongxi Punishment University have all been made. There is an abnormal situation-" Wang Yijun entered the door and said: "The bloodstains extracted from the desk at the murder scene made a set of male DNA data, not the victim Ning Yuanfu, nor the suspect Yuan Sitian..." Xue Yuanjian was surprised: "Could it be a mistake?" "No, it won't. I specifically asked Director Rao, and she did it herself. If the on-site inspection material is 'hair', it can't be ruled out that it was left by our on-site technician? Now it's 'splattered blood', which can only be left by a man's injury. Wang Zhi continued to analyze: "The situation is very complicated: it is most likely that there was a man at the scene at the time of the crime, and he happened to be injured; Or maybe a man went to Liu Guanglan's bedroom before or shortly after the crime and was injured at the desk and left blood stains? Technology alone can't be determined—the blood stain was left on the night of January 6. Wang Yijun is very professional and cautious, and pays great attention to all traces and physical evidence related to the "Ning Yuanfu disappearance case", and has communicated and confirmed with Ai Chunguang one by one before.

"Technology can't do it. The widow could be arraigned: Did any other man go to her bedroom before and after the crime? And - where did her desk come from? It could also be the blood accidentally shed by the porter..."Xue Yuanjian said after groaning: "If there was really a man at the scene at the time of the crime, he was most likely involved in the crime and was injured... Zhang Ju and Cheng Da are 'in trouble'! Speaking of which, Xue Zhi couldn't sit still any longer. He stood up and grabbed the work bag that had been prepared, and urged: "Hurry up and go-go to Tongxi!" "Do you want to report to the money bureau first?" Wang Zhi asked. "Not yet. Let's figure it out and talk about it. As Xue Yuanjian spoke, he had already walked briskly to the door of the office: the Qian Bureau assigned him in the morning to bring the backbone of technology and investigation to Tongxi Criminal University to support, in order to wait for Wang Yijun to rush back from other places - it had been delayed for half a day; I didn't expect to wait for a very strange DNA test result......

The Office of the Criminal Detective Group of the Ji'an Police Station. Inspector Ren and Li Wei watched the video materials collected in the early stage with full attention: Looking back from 22:05:17 on January 6, searching for the trace of the little white ape off-road vehicle point by point? The leopard traces the location of the car in chronological order on a map of the city, and slowly pursues it to the vicinity of the cross street - and the buggy disappears.

The two expanded the scope of the search video, and found that the little white ape car entered the city from the east of Ji'an Avenue, and at about 6 pm on the 6th, it drove into the East Street of Cross Street. There are few probes on East Street, and the vehicles are parked in a mess, so the off-road vehicle cannot be found for a while. "The little white ape said to himself: he was 'eating hot pot' that night, and Widow Liu called. I guess he parked his car in front of which hot pot restaurant? Really, it would be nice to ask more 'where did you eat hot pot' during interrogation. It also saves us from wasting our lives! Heh-" Li Wei was depressed and yawned: he majored in "interrogation", and he rarely watched videos for such a long time, and he was already tired.

"We are not gods, and some questions are only thought of and felt important as the investigation deepens." The leopard saw that Xiao Wei was impatient, so he said: "The East Street Night Market is bustling, and I often take my friends to it, and there is a 'Donglaishun Hot Pot Restaurant' that tastes great." It's only the fifth day of the new year today, I don't know if the door is opened? Let's go yo-yo and see which stores have cameras? By the way, go and fill your stomach - how? "Well, I'll see it!" Li Wei immediately agreed: After he visited the "diesel purchase point", he wanted to go back to the headquarters to read the case file and pester Yang Da - arraignment of the little white ape, it is better to take him with him? But the old inspector asked him to accompany him to find the track of the off-road vehicle, and he was embarrassed to refuse. From the bottom of his heart, he believes that Yuan Sitian was an "outsider" before the case, and it is not worth spending time investigating at all; Ni Yutong's kid is lucky—what he did today is the right thing!

East Street, Donglaishun hot pot restaurant. Boss Cai and his wife were cleaning the store, and someone pushed the door in? "Boss, the last sheep's hoof hot pot?" The lad shouted. "The shop has just opened, and it hasn't opened normally..."Boss Cai didn't finish his reply, and his wife agreed: "The boss really knows how to eat, and 'sheep's trotters' is our signature dish!" Please sit down first-" "Boss Cai, forget it if it's inconvenient. The middle-aged man said. Convenient, convenient, do small business, still afraid of visitors! Boss Cai hurriedly turned around: the store didn't prepare anything, and it won't be open until tomorrow, but his wife agreed, and he couldn't object. Then some fried tofu and spinach, and two people will eat. Thank you! After Li Wei finished ordering, he sat in the "No. 1" booth. Seeing this, the leopard sat down opposite Williams.

"Lao Cai, I'll go to the farmers' market, you hurry up and make tea!" After the proprietress finished speaking, she took off her apron and went out. Boss Cai made two cups of tea and brought them to the guest table. "Boss, we are from the police station, I want to ask you something?" Li Wei said. As he spoke, he took out a photo of Yuan Sitian and asked, "Have you seen this person?" After Boss Cai looked carefully, he said slowly: "He has been..."The first ticket business of the year, it was the police, he was strange? Sure enough, not only to eat, but also to inquire about people. "You know him, what's his name? When was the last time it came? How many people? The leopard asked, overjoyed!

"He's a regular customer who often comes to take care of my business years ago. But I don't know his name. "Boss Cai answered truthfully: There are so many people who come and go every day, and they are all guests, not relatives or reasons - how can it be possible to inquire about people's names." How can you be sure that he is your regular customer? Williams asked. The guest was white and thin, and he was very recognizable. He is especially fond of drinking, and he drinks until midnight! Most of the time he left, I closed the door. "What Boss Cai said is very affirmative." Is he from Tongxi? "Lao Ren asked: There are many people who look alike, and the little white ape is like a local." No, he speaks with a 'Jiangbei Yankee', and he looks like we're here. "Boss Cai said without hesitation.

The leopard and Xiao Wei glanced at each other, and said in their hearts: It should be like a "little white ape", although it can't be confirmed, ask - it is necessary! Inspector Ren looked at the probe and asked, "Is the monitoring in your store good?" How long can it be stored? "If you can find a video of Yuan Sitian eating hot pot, it will be conclusive. Boss Cai rubbed his hands and said, "The video is good... Ann's people said: Can it be kept for half a month, do you want to see it? "Then please show us." Old Ren Dao. Li Wei thought to himself: "It's been almost three weeks since January 6th. The video at that time has long been overwritten, what is there to see? Waste of life!" The old inspector wants to see it, and he can't object to it......

When the proprietress came back from grocery shopping, Chef Cai began to cook. The leopard, who didn't see the "6th video", decided to talk to the proprietress: The woman is responsible for serving the food and collecting the money, maybe she has seen the little white ape? The proprietress was a chatterbox, and quickly recalled-

"Mr. Bai" (note: the guests are white, as women call them) often come to eat hot pot, and like to eat "bullwhip" cooking. Last year, there were a lot of people who came during the lunar month, and they were usually alone. As the saying goes: one person doesn't drink, two people don't gamble. But Mr. Bai is different, he always sits on the card seat, asks for a bottle of "Gujing Gong", burns a bullwhip hot pot, plus a plate of peanuts, and drinks it late. The woman was particularly impressed with him!

Once, Mr. Bai came and wanted to go to the upstairs box, saying that "a friend is coming". The woman immediately agreed. Later, Mr. Bai's friend came, but there were only two men: an older one and a young man. The woman recognized the young man, who was the "Boss Fan" who sold daily chemical products in the gossip mall. She often goes to Boss Fan's store to wholesale detergents, and she recognizes it at a glance. Boss Fan estimated that something was wrong, so he left in a hurry after not eating for long. Mr. Bai didn't do as usual - he drank until midnight, checked out after drinking a bottle of liquor, and left with his friend......

The proprietress said with her eyebrows fluttering, Xiao Wei was bored and smoking, and the leopard was shocked when he heard it, but it was inconvenient to show it: he was familiar with the entire case of Ning Yuanfu's disappearance, and knew that this "Fan Kun" was the little boss of Fan's daily chemical industry, and he was also the younger brother of Ah Bao, the leader of Ma Zai, and the task force had arrested him before; Fan Kun and the little white ape eat hot pot together, which is also too strange!
