When Mo Haiyou knocked on the door, it happened that the middle-aged woman was hanging a blanket on the shelf outside the window with a small stool, and suddenly heard the knock on the door and almost slipped off the chair.

"I've been here many times today, really." She complained, put the blanket in her hand on the back of the chair, wiped her hands, and hurried to open the door.

When she saw the person standing at the door, the middle-aged woman was stunned for a moment, and the person in front of her was obviously talking to her mother inside, how could she change her clothes and appear at the door again? Could it be twins?

The middle-aged woman was a little stunned for a while, so she didn't say hello immediately. When Mo Haiyou saw her like this, he knew that she had confused herself with Yun Yeyao, so he said: "My name is Mo Haiyou, I am a forensic doctor in the police station, and I am not the same person who came just now, I have something to find the two of them, can you let me in?" ”

"Uh...... Good, okay, Mo... Forensic. The middle-aged woman finally held back a sentence, and quickly got out of the way and asked Mo Haiyou to go in.

The structure of the room is similar to that of the upstairs, and the door is open because there are guests, so Mo Hai can see the old man sitting by the window and Yun Yeyao's half body at a glance, he thanked the middle-aged woman and prepared to take off his shoes and enter.

The middle-aged woman hurriedly stopped him, "No, Mr. Forensic Doctor, you don't need to take off your shoes, you see I'm still wearing the shoes that came in from outside!" ”

"Oh, then I'm going to bother you, Auntie."

The sound of the conversation between the two people came into the room, Yun Yeyao immediately poked his head out and looked at the door, and saw that it was Mo Haiyou coming, he immediately ran out and said, "Xiao Zuo, is the autopsy over?" ”

"Not yet, just some preliminary results, overtime tonight, a whole bunch of things to be examined, and some things that will not be determined until the body is dissected." Mo Haiyou replied casually.

At this time, the information that the old woman could provide was almost finished, and Xie Yunmeng also stood up and said politely: "Thank you, the information you provided is very useful, then we will leave." ”

Mo Haiyou and Yun Yeyao at the door saw that Xie Yunmeng had finished asking, and they no longer went into the apartment, and the two of them stood at the door and waited for Xie Yunmeng. Mo Haiyou's right hand naturally rested lightly on Yun Yeyao's shoulder.

The middle-aged woman standing at the door of the kitchen looked at Yun Yeyao and Mo Haiyou, and forgot to continue drying clothes. The two people are the same height, the same body type, and their looks are exactly the same, if it weren't for the bangs on their foreheads, they would look softer; And the other completely combed his hair back to the back of his head, and his aura was serious and indifferent. Middle-aged women really don't recognize who they are.

Soon, the three of them left room 202 and returned to the living room of the murder scene upstairs.

Xie Yunmeng leaned on the side of the corridor, and after glancing inside, he said to Mo Haiyou, "Let's talk about your findings first." ”

"First of all, most of the wounds of the corpse were concentrated near the forehead and eyes, and it can be preliminarily estimated that the height of the murderer was much taller than that of the victim. Secondly, the victim fell backwards in front of the large closet, and it is very likely that the murderer was hiding in the large closet at the time, which makes it easy to launch a surprise attack on the person who opened the cabinet door. Mo Haiyou replied.

"Of course, the possibility that the murderer was an acquaintance of the victim cannot be ruled out. So everywhere I could hide people, I asked my colleagues in the laboratory to re-search fingerprints and dander and hair and so on. What we now need to determine is whether there is anyone else in the room besides the victim and his husband. ”

"That's what I thought, too, else?" Xie Yunmeng asked.

"Also, two incomplete bloody handprints were found on the victim's face and the handle of the murder weapon, the handprints on the face were horizontal, and I judged that the murderer should have pressed her head with his hand when he cut the victim's lips. But it doesn't make sense here, if you press the victim hard, the handprint should be very clear, and it is absolutely impossible to be incomplete. Moreover, the bloody handprints on the face are not as easy to deal with as on the hilt. ”

"The murderer left a handprint on the victim's face, which inferred that he should have held the knife in his left hand, and the handprint left on the handle of the knife was indeed a left-hand handprint. The jury is still not conclusive here. Because only the fingertips of the five fingers on the handprint on the handle were clear, and the rest of the parts were mixed with the blood, I tried to separate the undried blood stains on the surface, but the palm marks that appeared inside were so shallow that they were barely visible. ”

"The murderer must hold the hilt of the knife hard, otherwise he will not be able to exert his strength. I suspect that it is possible for the murderer to erase his original handprint and then place the victim's hand on it to make fingertip marks, which is why the palm part is so shallow and mutilated. After Mo Haiyou finished speaking, he looked at Xie Yunmeng and waited for him to speak.

Xie Yunmeng said: "Almost all of the investigation results on our side revolve around the male host, Ning Key. The first point is that Ning Key has a habit of going out to play chess with a friend at night, and often does not return home at night, and the tenants here are suspicious that Ning Key may be befriending a woman outside. But no one has ever seen this person's true face, and no one knows her identity. ”

"Second, the relationship between Ning Key and his wife is not very good, her wife often complains to her neighbors, and almost all the residents on the first to third floors know that Ning Key doesn't care about his wife. Ms. Pang, the first eyewitness at the scene, was very close to Ning Key's wife, and she heard Ms. Pang's husband say that she had made an appointment with a beautician tonight to go to Ning Key's house to do beauty with his wife. ”

At eight o'clock in the evening, they heard a fierce quarrel in Ning Key's house, so Ms. Pang hurried out to have a look, and met Ning Key who also went out, at that time there should be no blood on Ning Key's body, or Ms. Pang should not have noticed anything unusual about Ning Key, so she also talked to Ning Key at the door. After Ning Jian left, Ms. Pang entered his room. ”

"Third, the old woman in room 202 has the habit of going out for a walk at night, and when he and his daughter went back to the apartment before 8:20 today, they also met Ning Key, who left in a hurry at the elevator downstairs, and they greeted each other, according to the old woman's daughter, she didn't find anything unusual about Ning Key at that time, and her expression was also very calm."

"The testimony given by all the witnesses is at least temporally consistent, and it is preliminarily determined that Ning Jian had a conflict with his wife before 8:10 because he went out at night, met Ms. Pang between 8:10 and 15 and had a few conversations, and met the old woman and his daughter downstairs at the elevator on the first floor between 8:17 and 8:20. During this time, Ning Keydu behaved very normally, and no one suspected him. ”

At around 8:15, Ms. Pang entered Ning Key's house, as if the door was not closed at that time, and she went in directly. Then at around 8:20, Ms. Pang saw the horrific corpse and was so frightened that she fainted on the spot. There are two inferences that can be drawn from this: first, Ning Jian was the murderer of her wife, and after the killing, she pretended to talk to her neighbor as if nothing had happened, and then fled. At present, we have dispatched personnel to search for Ning Key throughout the city, and urgently notified all stations, airports, and toll booths on highways to strictly screen Ning Key to prevent Ning Key from leaving the city. ”

"The second inference is similar to what Forensic Doctor Mo just said, assuming that when Ning Key left, his wife was not dead, then the murderer could only be someone hiding in the room, but Ning Key left and Ms. Pang entered the room for only five minutes, how did this person use such a short time to commit murder? I think it's almost impossible. ”

"There was also a problem of escaping, there were still a lot of people coming in and out of the apartment at that time, and there was a lot of traffic on the road outside, even if the murderer succeeded in killing someone, he would not have been able to avoid all the neighbors while escaping. I asked the police upstairs and downstairs and around the people, and no one saw a stranger. ”

"Could it be an acquaintance who lives in the neighborhood or in this apartment?" Mo Haiyou asked.

"It's also unlikely, Ning Jian and his wife moved here more than two years ago, and there are no people in the neighbors here who knew them before, of course, this point will have to be carefully investigated after the personal information of each apartment resident and the surrounding residents to be determined."

After Xie Yunmeng finished speaking, he and Mo Haiyou looked at Yun Yeyao on the side at the same time, he had been listening and pondering, and he had hardly expressed his opinion until now, which was not like the performance he should have.
