"I have already confirmed this," Wu Xiumin said. "The problem does lie with us. The information is not strictly blocked!"
"A teacher from the Journalism Department?" Zhao Yu murmured, "Since you are Kong Xiaoxue's husband, are you... also familiar with Heyang Normal University?"
"There should be no problem with this person," Wu Xiumin replied affirmatively, "The reason why I came back so late is to confirm this person!
"The university he went to in the capital did not go to Heyang Normal University, and..." Wu Xiumin added, "This person is already an authority in Chengzhou in terms of journalism. He often participates in training and is very famous in the industry!
"Moreover, he has a keen sense of news. Our police officers are no match for him. It is not surprising that he deceived the news!"
"Fortunately..." Cui Lizhu smacked her lips, "He just expressed his opinion in the class group. If it was really publicized to the media, it would affect our investigation!"
"Fortunately," Wu Xiumin said, "I just told his wife Kong Xiaoxue and Kong Xiaoxue's classmates... In fact, even if he really releases the news to the media, it will be difficult for us to do anything to him!"
"It doesn't matter," Zhao Yu said calmly, "We have already issued a revelation about the corpse identification, which means that the discovery of four female corpses from Heyang Normal University to Zhenlou has been spread and everyone knows it!
"It has no impact on our case!"
"Team leader," Wu Xiumin added, "after the 3D portraits came out, I have asked every one of Liu Weiwei's classmates, and none of them knew these dead people!
"Probably, it has nothing to do with the students in their school..."
"You said..." Cui Lizhu suddenly thought, "Back then, the murderer brought a strange woman into the school. Shouldn't the guards be aware of it
"At that time, the school was in summer vacation, so the guard might have some impression, right
"If...we find the guard at that time, right..."
"It's been more than twenty years!" Ran Tao smacked his tongue, "Whether the guard at that time was still alive is a question!"
"The boss often says that as long as there is a glimmer of hope, we must fight for it with all our strength!" Cui Lizhu said firmly and resolutely, "Sometimes, what a person sees in a flash of thought may never be forgotten in a lifetime! Maybe, we can find something What is it
"Boss," Cui Lizhu said, "Anyway, my work is now done. In this case, leave the doorman affairs to me!
"I will contact the school right now and ask them to give me the list of the janitors back then. I will look for them one by one!"
Previously, Zhao Yu sent Cui Lizhu to investigate the situation of Liu Weiwei and Nie Ya. Through the investigation, the possibility of these two couples participating in the murder has been basically ruled out.
Therefore, Cui Lizhu's mission has been completed.
"Well..." Zhao Yu smacked his lips and sighed, "Okay! You can also try it, but... I can help you narrow down the scope!"
"Oh? Scope?" Cui Lizhu asked quickly, "What scope?"
"Now that Liu Weiwei's suspicion has been eliminated, then... we can make a simple assumption," Zhao Yu said, "In the year when the National University Games was held, that is, during the summer vacation of 1997, Liu Weiwei wrote down That "My Secret"...
"Then, he lost his manuscript in the winter of his sophomore year, which means that if the murderer got his manuscript and was ready to kill someone, he could only do it during the winter vacation or summer vacation of the next year!
"And the manuscript is written about summer vacation, so... I think it is most likely that the murderer committed the first crime during the summer vacation of 1998!
"Secondly, forensic doctor Zhang said that female corpses No. 2 and 3 were of the same year, so it should be 1999. Now it is discovered that female corpses No. 4 and 5 are of the same year, so it should be 2000!
"So," Zhao Yu said, "when you go to investigate, just focus on the past three years!"
"Oh..." Cui Lizhu nodded.
"It's summer!" At this time, Zhang Peipei suddenly added, "We found the remains of a kind of scavenging bacteria on the bones of the previous four bodies. This kind of bacteria only becomes active when the temperature is higher than 20 degrees.
"So, the first four victims can be judged to have been killed in the hot summer! But as for the fifth one, it is difficult to make an effective judgment yet because it is buried deep in the soil. However, according to the degree of decay of the bones, it should be the same as No. 4 The female corpse is from the same year, so the time is almost the same!"
"Okay, I understand," Cui Lizhu nodded, "I will ask Captain Mou for a few people to come with me later!"
"From 1998 to 2000, five people were killed in three years!" Ran Tao counted with his fingers, "Is this person... a whole year younger than Liu Weiwei? Isn't he their classmate
"In other words," Ran Tao frowned, "Have I done useless work before? Focused all my attention on Liu's only classmate?"
"Huh?" Cui Lizhu slapped her forehead and exclaimed, "Brother Tao, have you taken melatonin? Your thinking today is particularly strange!"
"Come on, let's do the math!" Ran Tao said while picking up the manuscript and writing on it. "Liu Weiwei lost his manuscript in the winter of his sophomore year. After that, there were all murder cases for three consecutive years...
"Then, we assume that a freshman who was a freshman at the time picked up his manuscript, and then the time this person killed according to the manuscript was the summer of his sophomore year!
"After that, I killed two in the summer of my junior year, and in my senior year... um... um... two more?"
"Yes!" Zhao Yu said, crossing his arms, "We have discussed this issue before. It is a bit unreasonable to still kill people in the summer of senior year!
"In April of that year, they had already ended their school career and went to various places for internships...
"If this person is still in the school..." Zhao Yu asked, "Should it be easy to find out?"
"Team leader," Zeng Ke suddenly spoke at this time, "while you were discussing, I quietly checked and found that the students who are one year younger than Liu Weiwei and the others do not live in Zhizhen Building!"
"Oh?" Zhao Yu was surprised, "Don't you live in Zhizhen Tower?"
"Yes," Zeng Ke said, "The records clearly show that because Zhizhen Building was renovated from a teaching building, and there were classrooms on the third floor, it was not convenient, so the school built another dormitory building that year. After Liu Weiwei’s class, there are only sports students left in Zhizhen Tower!”
"Wow," Ran Tao said with a smile, "athletic students love to cause trouble, and our school also allows them to live alone, hahaha..."
"A sports student?" Zhao Yu asked, "In other words, will the person who picked up Liu Weiwei's manuscript be a sports student?"
"The situation is quite chaotic," Zeng Ke said. "There are special recruits among the physical education students. Their dormitory is different from other departments. They are all mixed together. There are students from several seniors in the same dormitory!"
"This is troublesome!" Zhao Yu shook his head, "I remember... the school is very sure that during the summer vacation, there has never been a single student in Zhizhen Tower!
"Could it be that... our previous direction... was wrong!?"
"Wrong?" Ran Tao scratched his head, "What do you mean?"
"The murderer who stole or picked up Liu Weiyi's manuscript and then carried out the murder according to the manuscript," Zhao Yu said with surprise on his face, "is not a student of Heyang College!!?"
