Four days later, there was still no progress in the investigation.
Other than an old pimp's confession, the police suspected that female corpse number three might be a woman who worked in a nightclub, everything else was in a deadlock.
Within four days, the police had compared the DNA of a large number of related people, including the students, security guards, school workers, and teachers, but they still couldn't find a match.
According to the geneticists' DNA tests, they couldn't narrow down the scope of the DNA map. The criminal was very lucky. Among his close relatives, no DNA data was left behind.
In addition, the 3D reconstruction of the image and the comparison of the missing person's case were also making slow progress.
Including today, the special investigation group led by Zhao Yu had been in Chengzhou for almost half a month. No one would have thought that the case would reach such a stage.
Now, the police had expanded the scope of the search and started to target the sports students of the school, as well as other students related to the Zhenzhen building.
At that moment, in the special investigation group office, the atmosphere was slightly heavy.
No one expected that the case that seemed to be solved within a day would go further and further.
Now, the public media was in an uproar. The old murder case had attracted attention from all walks of life.
As the case happened on the university campus, it attracted the attention of the university students.
Although it looked calm on the surface, in reality, Heyang Normal University had long been pushed to the forefront of public opinion.
The school was naturally more anxious than the police. If they couldn't find out the truth, it would definitely have a huge impact on the school.
Not only would it affect the enrollment rate, but it would also seriously affect the school's reputation.
The power of the media was strong. So far, there were hundreds of vivid versions of the case on the internet. Some said that the school was involved in the underworld, some said that a classroom was a psychopathic murderer, and the worst was that there were people spreading rumors, saying that the school was a brothel back then, and that they organized female students to sell their bodies and so on. The stories were incredible and as ugly as it could be …
Under such circumstances, Zhao Yu and the others undoubtedly felt a great deal of pressure.
Zhao Yu then understood that this case was really different from the previous ones. Moreover, he had to ensure that he was a hundred percent dedicated.
So, in the past few days, he had returned to his old working state, and he was fully focused on investigating the case every day.
He didn't know why, but after Zhao Yu took it seriously, his tinnitus never happened again.
"Team Leader," Zeng Ke reported to Zhao Yu, "I can't get in touch with the owner of the bookstore and the phone shop. The school doesn't even remember his name …"
It turned out that according to the memories of the students and the school, there used to be a row of bungalows outside the Zhi Zhen Building. Those bungalows were rented out by the school, and many people started small businesses such as hairdressers, canteens, fruits, snacks, etc. Among them, the most popular were the rental bookstore and the telephone store …
This kind of campus shop was very popular at that time, and it almost became an inseparable part of the university life of the students.
It was precisely because of these shops that there was no way to standardize the management.
Zhao Yu thought about it. As the row of shops was very close to the Zhenzhen building, there was a possibility that the people in the shops had committed the crime.
Therefore, he had asked Captain Mou to investigate this a long time ago. Unfortunately, the management of those shops was relatively scattered. The shops were like a merry-go-round, constantly changing every year, so it was quite difficult to find them.
Zeng Ke told Zhao Yu that, so far, they hadn't found the owner of the bookstore and the telephone store.
Previously, Zhao Yu had carefully analyzed it. If the Murder Diary Case was related to the people in these shops, then at least the shops had been in the school for a long time.
After some confirmation, the police found that the bookstore, the telephone store, and the barbershop had been in operation for the longest time, which matched the criteria of the Murder Diary Case.
However, according to the memories of Liu Weiyi and the others, the barbershop was run by an elderly woman, so the barbershop had been ruled out.
The owners of the bookstore and the phone shop were both young men. So, Zhao Yu wanted to find the two of them and conduct a comparative investigation.
Unfortunately, the row of bungalows had been completely demolished in 2005. As the school couldn't find the lease contract from that year, the police couldn't find the two parties involved, nor did they know their names.
Liu Weiyi and the others also said that they only remembered that the two bosses were men, but they had never asked for their names.
The police found a few classmates who often rented books back then and asked them to draw portraits, but none of them could remember their names.
In addition, the situation with the telephone store was similar. The police could only investigate the information from the telecommunications bureau, but because of the long history, it would still take a lot of time.
Of course, in addition to these people, the police were still actively investigating and looking for people like the boiler worker, plumber, and even the cafeteria chef.
"Team Leader," Zeng Ke reported to Zhao Yu, "Lao Song's nephew has been found, and we are checking his DNA, but … You know, the possibility is not high …"
"Mm …" Zhao Yu nodded. Of course, he knew that although Lao Song was no longer alive, the police had previously extracted the DNA of Lao Song's relatives and compared it with the target.
So, Lao Song's nephew's DNA was similar, so he shouldn't be related.
However, in order to ensure that nothing went wrong, he still had to do what needed to be done. What if the nephew wasn't related to Lao Song by blood?
Just like that, the investigation continued, and Zhao Yu and the police detectives didn't rest for even a moment.
In the blink of an eye, it was already late at night.
Zhao Yu was the only one left in the office.
This time, he wasn't standing in front of the whiteboard. Instead, he was watching the video of the sorority party carefully.
Zeng Ke, Ran Tao, and the others had carefully reviewed the video of the sorority party and recorded any information that might be related to the Murder Diary Case.
For example, Lao Song's nephew had been found through this method.
After a few days of investigation, they had basically ruled out most of the clues. However, Zhao Yu was afraid that Zeng Ke and Ran Tao might have missed something, so he insisted on watching it again.
Zhao Yu said that he was going to watch it again, but in fact, he had already watched it for the umpteenth time.
At that moment, he was watching a video of the school leaders. The people sitting at the table were the old leaders of He Yang School, as well as the new leaders.
Among them, a current vice principal was sipping wine and sighing with emotion.
"If you ask me, it's absolutely impossible for us to not acknowledge the free will of the heavens!" He put down his wine glass and said to his colleagues, "The Zizhen building should have been demolished a long time ago.
Over the years, the sports department at He Yang Normal School has achieved good results. So, the school originally decided to demolish the Zizhen building and build an auxiliary gymnasium!
He then said with a mysterious expression, "If it was really demolished, then the bodies hidden in the garbage would have been found long ago, right?"
