Zhao Yu swore, but reality slapped him in the face.
After five consecutive days, there was still no progress in the investigation of the murder diary.
Zhao Yu was really puzzled. The answer was right in front of him, but there was still no sign of it. They had used all the technical means that they could use, but there was still no sign of the mysterious murderer.
In the past five days, they had investigated most of the guards at the Normal College. According to the school's information, there were only two guards who had guarded the Zizhen Building, and both of them were no longer alive!
Even so, the police still found the families of the two people and did a DNA test. After the test, it proved that their DNA did not match the one on the body bag, so they were ruled out as suspects.
At present, Captain Mou was looking for other guards, but because of the long time, many of them were no longer alive, so it was very difficult to find them.
In addition, there was no news from the 3D reconstruction images. The experts had restored all the heads of the five bodies, and the police had also released the portraits through various platforms.
But so far, no one had come to claim the bones. Although the police had some clues, they needed to verify them one by one.
Also, the progress of the suspect's DNA map had also encountered a setback. Through the analysis and comparison of the experts, they only found a few similar targets, but there was still a big gap between the DNA of these people and the suspect.
In layman's terms, these people who had similar DNA to the suspect were already related to the suspect. If they were to really search for them, it would be a lot of work, and it would be impossible to narrow down the scope in a short period of time.
In addition, the detection of the bones had also done their best. However, because there were too few clues found on the bones of the deceased, and no relics or clothes of the deceased were found, there was still no way to confirm the identity of the deceased.
In order to find the possible relics of the deceased, the police did not hesitate to turn over the entire garbage road, and they also dug deep pits under the big banyan tree.
If there was any gain in the past five days, it would be the comparison of similar cases. According to the situation of the deceased, the police found more than 100 missing cases that year.
Now, they were carrying out a detailed investigation, hoping to find out if there was anything related to the five murdered women in the missing cases.
However, it was obvious that this would take a lot of time.
Time, time …
In fact, the investigation of a case that happened more than 20 years ago did require enough patience. There were many things that could not be found just because one wanted to hurry up.
Zhao Yu naturally understood this, but for some reason, his heart was tangled with something and he just couldn't let it go.
Perhaps, it was because there was still a mission to find Xi Wei's vault waiting for him in Korea.
He was always worried that Miao Kun would call him at any time to urge him to return to Korea to complete the mission.
Because of this, his tinnitus not only did not improve, but it even got worse. But this time, Zhao Yu had learned his lesson. When his ears were ringing, he didn't show it, so no one noticed.
At that moment, Zhao Yu was not idle. He called the chairman of the Couplet Association, Liu Weiyi, into an office and questioned him.
"Yes, yes …" Liu Weiyi said. "Back then, the guard was an old man. When we came in and out, we all called him Lao Song. We didn't know if he was Lao Song or Lao Song. We also didn't know if his surname was Song or his name was Song. Anyway, everyone called him Lao Song!
"This person was very old," Liu Weiyi said. "He was almost 70 years old at that time, right? I don't know who he was, but he was still a guard at such an old age!
"However, this old man didn't care about anything. He just locked the door when it was time. We passed by the guard room ten times, and he was sleeping eight times!"
"Are you sure that there's only one guard?" Zhao Yu asked.
"Yes! That's right. From the time we moved into Zhizhen Building until we graduated, it was him! " Liu Weiyi said. "Police officer, I can guarantee that he definitely has nothing to do with the murder diary. You don't know, but his vision is very blurry, and he doesn't seem to be able to read. He usually listens to the radio …"
"Then …" Zhao Yu asked again, "Try to recall carefully. Other than the guard in your building, are there any other security guards or guards that you are familiar with?"
"Um … Well …" Liu Weiyi said very seriously. "Police officer, I'm really upset that such a big thing happened. Although I'm not the murderer, this case started because of me. I haven't slept much for the past few days!
"Ever since you asked me that question that day, I've been thinking about who it was. Who was it? But … "Liu Weiyi said in annoyance," I recalled so many people, but I didn't find any abnormal!
"I drew a list for myself and wanted to list all the suspects that I could think of, but in the end," Liu Weiyi shook his head and said, "I didn't write down any names!
"I really carefully recalled a lot of people, including my classmates, security guards, chefs, school workers, and even teachers, but I didn't feel that there was anything unusual about them!"
"To be honest, I'm quite an emotional person. I'm very sensitive to other people's reactions. I think that there's really nothing wrong with the people that I know.
"So, the more I think about it, the more I feel that my manuscript was lost, and it was picked up by a stranger …
"So, I don't know the real murderer …"
"Teacher?" Unexpectedly, when Liu Weiyi spoke, the word "teacher" was suddenly nailed to Zhao Yu's mind.
F * ck …
He was speechless. Could the real murderer be a teacher at the Teacher's College?
Thinking about it carefully, he felt that it was possible. In fact, it seemed … very likely.
A teacher would understand the situation in the school and the students' dormitory. Because of the teacher's identity, it would not arouse suspicion. Even if he brought a girl into the school, people might mistakenly think that the girl was a teacher's student.
For a university teacher, would he have a certain advantage when it came to chatting up strange girls?
Liu Weiyi said that there was no dedicated dormitory manager at that time, and the teacher was always a guest manager. So, the teacher knew the dormitory better …
Also, if the teacher wanted a key to the Zhenzhen Building, it didn't seem to be difficult …
Also, a lot of materials and tools were needed to open the garbage chute, put the corpse in, and then seal the garbage chute. If it was the teacher, wouldn't it be easier to get them?
Wow …
The more Zhao Yu thought about it, the more frightened he became. Could the truth of the case be like this? A teacher who looked kind and gentle was, in fact, a devil with a dark heart and cruel emotions?
In the end, when the teacher saw Liu Weiyi killing people, his desire to kill was completely ignited? So, he stole Liu Weiyi's manuscript and started to kill people according to the contents of the manuscript?
