All the evidence points to Principal Zhang, and now as long as one thing is confirmed, the case can basically be closed.
Guan Zengbin has the DNA taken from Zhang Mingliang's body, and if Principal Zhang's DNA matches, everything will be right.
Half an hour later, Guan Zengbin compared the DNA of daily necessities in Principal Zhang's house with those found in Zhang Mingliang's body, and we got an expected answer, the DNA matched.
Therefore we can draw a conclusion:
Four nights ago, Principal Zhang saw the note that Zhang Mingliang had left for him and thought it was from Hu Jiajia. So he came to the long-suspended construction site as promised, and he saw Zhang Mingliang. In the dark, he mistook Zhang Mingliang for Hu Jiajia.
Zhang Mingliang was worried about being discovered by the old Zhangtou who was watching the gate, so he took Principal Zhang into a building and walked up.
When they reached the fifteenth floor, Zhang Mingliang felt that the old man would not be able to spot the two at such a height, so he stopped.
Principal Zhang followed behind her, and all Zhang Mingliang left for Principal Zhang was a back view.
Principal Zhang fulfilled his promise.
Principal Zhang covered Zhang Mingliang's mouth with one hand. Zhang Mingliang, who had just finished the operation, was very weak and unable to resist.
In the dark, Principal Zhang didn't even recognize that this person was actually a transgender person.
Even if Zhang Mingliang is a ghost, he will not understand what brought him the disaster of killing himself.
Principal Zhang looked at Mingyue outside the building and smiled. Grabbing Zhang Mingliang's neck, he wrote the famous love poem on the wall:
Asking what love in the world is, it is only a promise between life and death.
Then he threw the body down from the fifteenth floor, and at the same time, a thief was caught by the old dog's trap.
When Lao Zhang went upstairs, Principal Zhang hid on the sixteenth floor. When Lao Zhangtou went downstairs, Principal Zhang followed behind Lao Zhangtou. He might have wanted to kill Lao Zhangtou, but in the end he didn't do it.
After going downstairs, Principal Zhang carried Zhang Mingliang's headless body on his back, and entered the sewer through a drain in the construction site. After walking about a kilometer along the sewer, Principal Zhang randomly threw the headless body in the sewer, thinking that it would never be discovered by anyone.
Then, Principal Zhang ran away from another place.
"Is this your conclusion?" After listening to Guan Zengbin's reasoning and analysis, I couldn't help asking.
"That's right, it's very logical." Guan Zengbin nodded and said.
I shrugged, sat on the sofa, and stretched out three fingers: "Well, I will ask you three questions about your analysis. If you can answer them, I will assume that the facts are what you said .”
"Okay!" Guan Zengbin sat opposite me, raised his eyebrows, and stared at me with a pair of big eyes.
"First question," I said. "Where did the barrel that old man mentioned earlier go? Your story doesn't mention that."
Guan Zengbin thought for a moment, and then slapped himself on the forehead: "Yes, the one that cut off Zhang Mingliang's head was a very sharp weapon. Of course, Principal Zhang couldn't be holding it in his hand, so he must have something to hold this weapon. Then That barrel is what holds the weapon, so Zhang Mingliang won’t be suspicious.”
"Carrying a bucket is more suspicious! Then the second question." I continued: "If Principal Zhang kills someone and hides on the sixteenth floor, there will be traces, but there is no blood on the scene except for the fifteenth floor. And Since he already killed one person, why didn't he kill Lao Zhangtou, so he wouldn't be afraid of what Lao Zhangtou would find out?"
Guan Zengbin's face was pulled down, his eyebrows were furrowed, and he rested his hand on his chin: "Principal Zhang only kills Hu Jiajia, and the rest are not killed."
"The third question." I continued to ask: "Since Principal Zhang thought that he would not be found by throwing the body in the sewer, why did he disappear? Isn't this place without three hundred taels of silver to make people doubt him?" ?”
"Well, maybe he thinks that the old man saw him..." Guan Zengbin scratched the back of his head and said.
I stretched out a finger and shook it: "Then why didn't he kill Lao Zhangtou?"
Guan Zengbin smashed a cushion on the sofa on my head: "Psychopathy!"
I cradled the cushion in my arms, thinking about the circumstances of the case.
Principal Zhang undoubtedly did something to Zhang Mingliang, but it didn't look like Zhang Mingliang killed him. Could it be that Principal Zhang wasn't the murderer, but someone else? Perhaps the young man caught in the trap was the real murderer
No, the time is not right.
It was about ten o'clock when the old Zhangtou heard the movement, and it was about ten ten o'clock when he arrived at the place. And at this time, the young man escaped the trap and ran away. Then the old man was about to go back, but he heard something from upstairs. It was around ten fifteen at this time.
With the physical strength of the old Zhangtou, he went upstairs layer by layer and observed the movement of each floor. It was about eleven o'clock when he reached the fifteenth floor. According to Guan Zengbin's autopsy report, Zhang Mingliang had just died at this time. Even if there is a few minutes, the young man downstairs is absolutely impossible.
That young man can never fly.
Nothing to say all night.
Director Shao's office.
The search for Principal Zhang has already started in the whole city, but there is still no trace of Principal Zhang, as if he has evaporated from the world. Mary retrieved the information of the train station, bus station and airport, but found that Principal Zhang did not purchase tickets through his ID card at all. The monitoring of various streets did not show that Principal Zhang returned to his office or his home.
The strange thing is that the surveillance near Principal Zhang's home seemed to have been sabotaged in those few days.
"I don't think the headmaster committed suicide in fear of guilt." Mary, who was eating watermelon, said vaguely.
"Wu Meng, team leader, we have a clue." Xiao Liu pushed open the door.
Team leader Shao still held the white teacup and asked, "What's the matter, in a hurry, is someone dead?"
Xiao Liu wiped the sweat profusely from his head: "Yeah, someone found a dead body on the mountain, and it was rotten."
"By the way, Xiao Guan, take that box with you," Team Leader Shao said.
Guan Zengbin's eyes lit up, and he said, "Is this the toolbox of Forensic Doctor Yang?"
"Yes, specially made." Team leader Shao said: "I said before, maybe one day this box will fall into your hands."
"Then forensic doctor Yang?" Guan Zengbin asked, "I haven't heard from her for many years."
Team leader Shao waved his hand, as if he didn't want to talk about these things: "Go, there are still corpses waiting for you at the scene."
The weather was still hot like a stove, so Gu Chen and I simply took off our shirts and watched Guan Zengbin dissect a corpse in the tent built temporarily by the villagers.
Compared with Zhang Mingliang's corpse, this corpse is worse than Zhang Mingliang's. The face is so rotten that we can't tell who it is, but after the last shock, Gu Chen and I are obviously on good terms. a lot of.
Seeing Guan Zengbin sweating profusely, Gu Chen and I were a little ashamed sitting here, so I took a towel, poured some mineral water on it, and walked to Guan Zengbin's side.
Guan Zengbin carefully dissected the corpse, and I wiped her sweat with a towel: "Did you find anything?"
Guan Zengbin held the dissection tools in both hands, and let me wipe her sweat, and then said slowly: "There is a discovery, and there is a big discovery, do you know who this person is?"
"Who?" I asked.
"This person is Principal Zhang!" Guan Zengbin glanced at me and said lightly.
Principal Zhang's body was found here, and it seemed to be very decomposed.
"Do you know the time and cause of death?" I asked hastily.
Guan Zengbin nodded, not knowing what he was operating in the box: "The time of death was probably a few days ago, and the time calculation should be a few hours after Zhang Mingliang's death. It hit the head."
Principal Zhang killed Zhang Mingliang, and then someone killed Principal Zhang
"Xiao Liu, how was the body discovered?" I called to Xiao Liu who was taking notes in the distance.
"The body was found on the mountain. Someone buried a pit, but it wasn't deep. Someone passed by and found a piece of clothing exposed. That's how it was discovered." Xiao Liu shouted.
"Is it buried deep?" I asked.
"Yes." Xiao Liu said: "The villager said it was easy to find, but there are not many people going to that place."
One wave of ups and downs and another wave of ups and downs.
Who are the people who know about Principal Zhang's actions
Anyone who knows about Principal Zhang's actions must be someone who has a good relationship with Principal Zhang, and I just happen to know that there is such a person.
Could it be that he was the murderer who killed Principal Zhang
