Du Dayong thought so, but why? It stands to reason that such a murderer would never use such harsh methods to deal with an ordinary teacher, not to mention that this teacher has a very good reputation and ethics.
Only then did Du Dayong remember why Deputy Director Sang had to force this case on him. Maybe this case had already been circulated by the Criminal Investigation Corps. After a tour, it should have been in the same state as him, without any clues.
Du Dayong was still a little unwilling to think about it, so he placed the dossier materials and photos separately, showing the photos wherever he saw them, and then started writing and drawing in his notebook, but after a while he got distracted again.
"No, I have to go and take a closer look at the scene. You can't come up with new ideas just sitting here thinking about it for a long time."
Du Da said something to himself.
After going downstairs, I found Wang Binbin and two assisting police officers, and drove to Changle Lane.
When Wang Binbin saw that his director looked ugly, he was so frightened that he didn't dare to say anything more. The two co- police officers were also silent.
I guess these three people all doubted whether the entire institute had received honors and only the director had not?
But when the car drove to Changle Lane, Wang Binbin knew immediately.
"Du Suo, have you taken over the murder case of the female teacher?"
Du Dayong glanced at Wang Binbin in the dark.
"Don't you know how to use the flashlight? Just press the button and it will light up."
Wang Binbin scolded Du Da and quickly turned on the flashlight.
"Don't worry, you are the leader now. Are you ready to take over? Didn't you keep your mind at home? You knew there would be no suspects here? Can't you remember what you should do when entering a crime scene at night? Yes
If you come out with me, your vigilance will be gone?"
Wang Binbin’s scalp exploded when he criticized Du Da.
"Du Suo, I know I made a mistake, and I will definitely not make a similar mistake next time."
Wang Binbin really knew that he was wrong. He should have turned on his flashlight as soon as he entered the alley and searched for places where people could easily hide. After making sure that no one was around, he could enter the communication stage.
Du Dayong took the flashlight from a cooperating police officer, and first took out the photos of the crime scene from his pocket to observe.
"Wang Binbin, stand here and I will stab you with electric shock. Don't hide."
After Du Dayong finished speaking, he pinned Wang Binbin to the position where Pan Guanghui was stabbed.
Then Du Dayong started looking for a hiding place again, but all the hiding places here, if he rushed towards him, would not stop Pan Guanghui from alerting him. As long as he was alert, Pan Guanghui would turn around or stick to the surrounding buildings in the alley.
Things walk.
Then the murderer should look like a passerby, and then just come up and stab him? Du Dayong thinks it's wrong! The murderer can also have the ability to predict the future. Knowing that Pan Guanghui has no one to pick him up today, he is definitely going to take this alley? Isn't this right?
possible.
There is surveillance at the gate of the middle school, which can prove that the guard just stood at the gate and watched, and then returned to the guard's office.
Liu Siji did not have the time to commit the crime, because he was drunk and drank tea with the students' parents until someone called him to tell him that something had happened to Pan Guanghui.
Similarly, the reporter did not have the time to commit the crime. The reporter was still at work when Pan Guanghui was stabbed, because he only discovered the situation after returning home from get off work. By that time, it was already 10:20 in the evening.
No effective clues were found from social relations, because the investigators at that time had reviewed all the call records of the couple, and even the home phone call records were clearly checked.
This case does not involve financial intrusion or sexual assault. So far, no emotional reasons have been found, and no enemies or grudges have been found between the couple.
In addition, the two people have a good reputation! Du Dayong really can't think of any reason at the moment. Pan Guanghui suddenly walked into the alley and went home this way, or was stabbed twice by the murderer not long after entering the alley.
The fragrance disappears and the jade dies.
The forensic autopsy and autopsy examination concluded that based on the location of the knife edge and the channel formed by the knife edge in the body, it should have been stabbed by a person over 175cm tall with a knife.
The investigators originally suspected whether there were students, but they ruled out all students on this basis.
There were only three people with the right height, but these three people were picked up by their parents, and there were only two people who were not picked up, but these two people lived not far from the school gate.
Besides, which student can find the location of the victim's abdominal aorta so calmly? He can stab him twice in a row, draw the knife and retreat far away without leaving any traces at the scene. How can he be so calm?
Du Dayong couldn't even think about it! Because Du Dayong thought that even if he was a policeman, his skills were moderate and his thinking was relatively calm. Compared with the murderer's methods of committing crimes, he couldn't do this.
Du Dayong then called Wang Binbin to the entrance of the alley again, and then he hid in a dark place at the entrance of the alley, and then let Wang Binbin walk in. When he walked in, he could not look both ways. Du Dayong tried to follow him again, but Du Dayong found this method
No, Wang Binbin will still be shocked. Then Pan Guanghui is not deaf or stupid, she can react completely.
