First, starting from this unit building, Xiao Zhang stood at the door of Su Nan’s house and chatted with the neighbors, and then asked everyone to go back and then come to ask each other. There are only six floors in this building, and Xiao Zhang chose the order from bottom to top.

The first middle-aged woman in her forties who was asked by Xiao Zhang, said that although she lived in the same building with Su Nan, she rarely dealt with her. Speaking of Su Nan's death, there was a kind of gloating that could not be concealed in her expression.

At the home of the deceased Su Nan, Wang Changping directed his subordinates to search every corner of the room, and did not find any special places. The forensic personnel did not collect suspicious footprints and fingerprints on the spot.

The furniture in the bedroom does have signs of movement. If the deceased once blocked the bedroom door with furniture, it means that the deceased believes that there is danger in the living room outside. In this case, there are two possibilities. One is that the deceased takes the initiative to move the furniture away for some reason (such as thinking that the danger is lifted), and the other is that the murderer chooses to enter through the window.

Suppose the murderer leaves the living room and goes around to the downstairs and climbs up from the platform, then the deceased has enough time to prepare for defense, but why are they both killed by the murderer? Is there more than one murderer?

The doors were blocked, so I wouldn't forget to close the window. Wang Changping subconsciously touched the glass, and Feng Chuan was poking his head out from under the window, panting and said, "It's hard to climb. It rained so heavily last night. Those who can climb up should have received relevant training."

It was almost noon, and the investigation of the scene came to an end. Wang Changping announced the withdrawal of the team, leaving only one auxiliary police officer to guard the scene. Two bodies were taken off the wall and transported away in a black canvas bag. The computer was a key physical evidence and needed to be moved back to the police station.

Outside the cordon, the flat-headed child was still standing there. Feng Chuan asked the others to go back first. He decided to chat with the child.

"Little kid, I am a policeman. Do you have anything to tell the police uncle?" Feng Chuan bent down kindly.

The flat-headed child looked at Feng Chuan, but his mouth was closed, and he didn't dare to say anything.

"Don't be afraid, uncle won't tell others. Uncle's eyes have undergone surgery, so it turns out like this. In fact, I'm the same as everyone else, open my eyes to see things, close my eyes to sleep." Feng Chuan understood why the child was frightened. His pair of strange pupils even had a little timid adult woman who was slightly timid, let alone the baby who was still dry.

The flat-headed child shook his body back and forth, and after making a lot of determination, he said carefully: "I saw a ghost last night."

As soon as he finished speaking, a sneer came from the side. It turned out that the words just now were heard by a half-aged child of fifteen or sixteen. He was imitating the tone of a flat-headed child and making jokes with the people around him.

Feng Chuan scolded a few words, then pulled the child to the side, pointed to Su Nan's house and asked, "Did you see a ghost there?"

"Yes, my family lives opposite." The flat-headed child replied.

"Can you tell my uncle more specifically?" Feng Chuan asked, the case seemed to be moving in a more complex direction.

"When I fell asleep last night, I was suddenly woken up by screams, so I turned on the lights. My mother was sleeping next door, and she was also woken up, and asked me loudly what to do when I turned on the lights. So I turned off the lights, but I felt scared. Fortunately, the lights on the opposite side were on, so I was not so scared. I don't know how long I fell asleep again, and suddenly I heard the screams again. I woke up again and saw that the lights on the opposite side were still on, so I continued to lie down, but I couldn't sleep anymore." The flat-headed child described squeakingly.

Halfway through the words, the flat-headed boy turned his head nervously and looked around, as if he was worried about something.

"What happened later?" Feng Chuan asked anxiously. He hated people who kept silent about their speeches, which made him even more annoying than the commercials in the middle of the TV series.

"Soon, the light on the opposite side went out. The surroundings were very quiet. After a while, I felt something might have happened on the opposite side, so I walked to the window and looked at it. The curtains were not closed opposite. Their computer was just under the window, and the computer was on. There was a person, no, there was a ghost sitting behind the computer, and the round thing next to the computer was a bit like a human head. Then, the ghost lifted the human head and twisted it around his neck. Suddenly the computer flashed, and the ghost stood up from behind the computer. At that time, I was already scared to death. At this time, the ghost seemed to see me, and it also walked to the window and slowly took off his head..." The flat-headed boy said tremblingly.

"What happened later?" Feng Chuan asked.

"Later I fainted and woke up and found myself sleeping in the bed. I told my mother about the haunted thing opposite. My mother told me that it was just a dream. I couldn't figure out whether it was a dream or a real thing." The flat-headed boy said.

"When did you wake up this morning? It was when the police arrived at the community and many people in the community knew that something happened to the other person on the other side." Feng Chuan asked. The child's thinking is relatively simple, and there is a possibility of being induced by the environment.

"Yeah." The flat-headed boy lowered his head, "but there is one thing that proves that it may not be a dream."

"Is it okay to tell my uncle?" Feng Chuan adopted the Huairou strategy.

"I was so scared that I pissed my pants before I fainted. When I woke up, there were signs of pissing on my pants, but there were no on the bed." The flat-headed boy said with a blushing face.

Feng Chuan wanted to ask a few more questions. At this time, a middle-aged woman ran over with a serious face and pulled the flat-headed boy away without saying a word. Looking at the two of them leaving, Feng Chuan guessed that they were a mother and son. Although they could not hear what their mother was talking about, they were obviously scolding the flat-headed boy.

It was really incredible. Feng Chuan looked up and saw that the distance between buildings in Shilitang Community was very narrow.

The case is of great importance. Yancheng Police Bureau has established a special task force, with senior party officials of the police station and director as the team leader, and Wang Changping, the captain of the Criminal Investigation Detachment, as the deputy team leader. Feng Chuan and Xiao Zhang are both members of the special task force.

After lunch, Wang Changping convened all the police forces that can be mobilized in Yancheng City for a meeting. At the meeting, everyone asked to act separately and arrest the murderer as soon as possible. Li Yadong, deputy director of the Iron Wharf Police Department, and other branch offices, all the police from the police station attended the meeting and each received the corresponding tasks.

After a busy afternoon, the task force members met in the evening to classify the clues collected and comprehensively integrate the case information to carry out the next action.

1. The victims are both outsiders and the local relationship is relatively simple.

2. The residents in the community did not have a deep impression of the couple. Some residents said that the hostess in Room 602 of the same building had a fierce dispute with the female deceased not long ago over raising a dog.

3. The property management said that it was insufficient staff and usually cooperated with the streets and communities to do basic work such as population registration and water and electricity bill collection. It did not do well in security and promised to do its best to improve it in the future.

4. The man who called the police station to report the case in the morning was very suspicious. After investigation, the phone was dialed from his mobile phone. It was a local number in Yancheng, but the holder was not registered.

6. On the night of the incident, the female deceased returned from a business trip from Shaocheng. The person who finally saw the female deceased was a black car driver. There is evidence that the black car driver continued to operate on the road that night, and ruled out the possibility of his crime. The black car driver has been transferred to the traffic management department for illegal traffic management laws.

7. The last person who saw the male deceased was a cleaning staff member, which was 7 o'clock in the evening. She said that the male deceased was no different from usual.

8. The autopsy report was released, and the death time was between 12:00 and 3:00 in the morning, which was in line with the guidance left by the murderer on the computer. The cause of death was that he was shot by a nail gun on the forehead, and one shot was fatal. However, it is impossible to determine whether he died at the same time.

9. Except for a fatal shot on the forehead and the wounds that nailed the two deceased to the wall, no nails were found on the scene that leaked or missed, proving that the murderer could use this kind of crime tool very skillfully. The one that cuts the deceased's mouth should be a dagger, a fruit knife and other knives.
