As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

Guan Hongyuan frowned and said, "Maybe he just miscalculated?"

"No, I think the murderer could have planned to kill two men and cleaned up the scene so thoroughly, so he wouldn't have made a mistake. Or the possibility of making a mistake is not high. On the contrary, another possibility is more likely."

"That is..."

Ye Lin strode to the front of the projection screen and tapped the big hole on the screen with his fingers.

"This place was originally dug to bury a person!"

Bury only one person?

The atmosphere in the conference hall suddenly became quiet, and everyone was shocked by Ye Lin's inference.

Looking at the earth pit in front of me, combined with my previous experience in handling cases, it seems that the depth of this pit is not enough.

Guan Hongyuan didn't say anything. He turned the document in his hand to the first set of photos, which was what it looked like before excavation.

In the photo, a skeletal hand stretched out from the soil, and he remembered clearly that the forensic doctor only dug a very thin layer of soil and found the body.

At that time he thought it was washed away by rain. Now according to Ye Lin, the pit that was originally used to bury one person now has two people buried in it. It really cannot accommodate both of them, and there is not much soil on top.

"Then why are there two people inside?" Xiao Peng asked, raising his hand.

Ye Lin smiled calmly, "I will make a bold guess about the situation at that time."

"There are at least three people now, maybe more."

"After victim A was killed, the remaining people began digging a hole. Since they were only burying one person, the hole only needed to be larger than one person's body."

"And just after the pit was dug, they worked together to put Victim A in it, and that's when the murderer took action."

Ye Lin picked up a pen from the table and stabbed it in the air. "The murderer attacked Victim B from behind and then pushed Victim B into the pit. That's why there are two people buried in the pit that was supposed to be used for one person."

After Ye Lin finished speaking, there was no response in the conference hall for a long time.

Everyone was thinking, they wanted to find something unreasonable, but the more they thought about it, the more frightened they became. Ye Lin's inference seemed very reasonable, at least it made sense logically, even more so than a strong man killing two people.

Seeing that everyone gradually understood, Ye Lin continued, "So, there are two cases here. One is that the murderer and victim B killed victim A together, and the other is that the murderer killed victim B."

"And." Ye Lin paused.

"We previously speculated that the murderer might be a strong man, but this may have to be overturned."

"At this point, even a thinner man or even a woman could have committed this crime."

Ye Lin's words once again shocked everyone present. This inference completely overturned the previous direction of the investigation.

Previously, the investigation focused on tall and strong adult men, but now even women are possible, and the scope of the investigation has expanded a lot.

This undoubtedly added difficulty to the investigation, and everyone's brows were furrowed even more.

Guan Hongyuan saw that the atmosphere was a bit low, so he quickly clapped his hands, "What Xiaoye said just now is very good, and this is also an idea. Then let's first determine the identity of the deceased, and then study the murderer's motives and methods of crime."

"Hey, Xiao Xu, you contacted the school. Is there any news about the identity of the deceased?"

"Hey." Xiao Xu scratched his head, stood up and said, "Captain Guan, I asked the school security department, and there have been no missing students in the past five years, not to mention the past three years."

"That's impossible. Two grown men. The school didn't lie to you, did it?"

"No, I have contacted their school leaders. They are also having a headache now. They hope that we can solve the case as soon as possible. Otherwise, many students will go to the grove to watch the fun every day."

"The main reason is that they are not students of the school. Now many parents say that there are security issues at the school and are making trouble with the school. They will not lie to us at this time." Xiao Xu explained.

After hearing what Xiao Xu said, everyone fell into deep thought again. If the identity could not be confirmed, the subsequent work could not be carried out at all.

"Everyone, think about it again. Do you have any new ideas about identifying the identity?" Captain Guan looked at everyone.

Several people shook their heads and said nothing.

Guan Hongyuan placed his last hope on Ye Lin, "Xiao Ye, what do you think?"

Ye Lin lowered his head and said nothing. His mind was constantly calculating. He whispered, "Two young men around 22 years old died on the university campus. The school has no missing records yet."

"Captain Guan, I have a true story here. Please listen to it and see if it has any reference value." Ye Lin said.

"Tell me about it." Guan Hongyuan said seriously. He had to say that Ye Lin was really amazing. Several key points of the case were discovered by Ye Lin.

"Everyone, I just graduated from the police academy. In my class, I heard from my classmates that a buddy went to work in the unit right after graduation. As a result, there was a big case in the station, and this guy went there directly without contacting his family.

As a result, his family thought he had lost contact and went directly to the school. The school had no choice but to contact his unit, which allowed him to call home, and his family knew that he was not missing. "

Ye Lin looked around at everyone and continued, "What I meant by this is, is it possible that these two people are graduates, the kind who have already graduated and can leave school at any time."

Guan Hongyuan understood, his eyes lit up, and he said to Xiao Xu: "Contact the school immediately and ask if they have received such calls or parents looking for graduates."

"Yes."

"Captain Guan, why don't we go together?" Ye Lin said.

"Okay, then Xiao Xu, let's go to school together."

Ye Lin always felt that there was something wrong with the security department of this school. They casually said that no students had gone missing in five years. They probably thought Xiao Xu was young and just made a random remark.

Many times, the information that they think is unimportant and there is no need to tell the police is the most critical information.

......

Yue Province University of Technology.

Zhao Changde, the head of the security department, sat in the boss chair with an impatient look on his face. "Captain Guan, I have said this countless times. Your young comrade has also come here many times. I have said everything I should say. There is really nothing more to say."

Looking at his attitude, Ye Lin understood that Xiao Xu would not be able to get any useful information out of him before.

"Chief Zhao, this time we're here not only to find out whether there are any missing persons, we also have some other things we want to ask." Ye Lin said.

Section Chief Zhao was stunned for a moment. Who is this young man? Their team is in charge. When will it be his turn to speak?

But he was too lazy to care about the police force. He just wanted to get rid of the police as soon as possible. These people were annoying and slow in solving cases. He still had to go play cards later.
