After committing a thousand perfect crimes, he joined criminal investigation

Chapter 40 Dormitory 308 (seeking further reading)

For a case, the direction of investigation largely determines the outcome of the investigation.

Because for the police, manpower, material resources, and energy are limited.

For example, if it is determined to be a murder of love, then most of the energy will be focused on investigating the people around the victim, especially suspects with emotional entanglements.

However, if the investigation direction is wrong, a lot of time will be wasted in the early stage and the best time to solve the case will be missed.

At this time, if you want to adjust the detection direction, the difficulty will be exponential.

So when Wei Chengye asked about the direction of the investigation, everyone present looked at Peng Jun.

Peng Jun did not answer immediately, but looked at Wu Wenhua, and after the other party nodded, he said:

"After Lao Wu and I analyzed the case, it was decided that I would lead a team to focus on investigating Diao Aiqing's interpersonal relationships.

Another group, led by Lao Wu, conducted a platoon investigation around the slaughtering experience. "

Two detection directions, a two-pronged approach, it will not be said that there is no way out after taking one path.

"good."

Wei Chengye nodded with satisfaction: "But I have to remind you that there are still six days left before the time required by the superiors to solve the case."

Six days~
  As soon as these words came out, the atmosphere instantly became depressing, and everyone had a solemn look on their faces.

Wei Chengye said nothing when he saw this.

There was nothing he could do. Now the case was spreading on the Internet, and everyone in forums and media videos were paying attention to it.

Don't talk about them, even the pressure above is not that great!
  Peng Jun looked at everyone at this time: "You heard me, comrades, we don't have much time left."

"Next, we will divide into groups, Tang Zhengyang, Sun Youmeng, Gao Yi... you guys will follow me to investigate Diao Aiqing.

Wei Qiang, Zhou Peng... You guys are working with Captain Wu to investigate the suspected murderer. "

Peng Jun must have discussed it with Wu Wenhua beforehand, so he quickly allocated manpower.

But after the distribution was completed, Peng Jun noticed Gao Yi in the lower row~
  From the beginning of the meeting until now, he spent most of the time staring at the information in his hand. Even though the meeting was about to end, he still had no intention of looking up.

"Digest yourselves, and start taking action after digestion!"

At that moment, Peng Jun shouted to everyone, then left the seat and came to Gao Yi's side.

At this time, Peng Jun found Gao Yi looking at a photo.

The photo was very familiar to Peng Jun. It was a travel bag used by the murderer when he dumped the body in Huainan University.

The bag was not big, about 60 centimeters long and 30 centimeters high. Because it was contaminated with human tissue, the inside of the bag was mixed with blood and grease, and it looked very oozing.

But Gao Yi was looking at it intently at the moment, which aroused Peng Jun's curiosity, and asked immediately: "What, is there something wrong with this photo?"

"Team Leader Peng!"

Gao Yi's train of thought was interrupted. He looked up and saw Peng Jun looking at him with a smile. He stood up and said, "There is nothing wrong with this picture."

"There's no problem and you're still looking at it so absorbedly?"

Peng Jun smiled.

There is nothing wrong with this photo, but do you take it seriously?

But as soon as he finished speaking, Gao Yi picked up the photo and pointed at the details inside the travel bag:

"It's okay if the bag is a very ordinary travel bag, but here..." Gao Yi pointed to the wear marks on the two ends of the bottom of the backpack and said:

"There's a big problem here."

"Oh?"

Hearing Gao Yi say there was a "big problem", Peng Jun suddenly became interested.

"Xiao Gao must have discovered another clue, right?"

On the side, Tang Zhengyang and others even looked sideways and cast curious glances.

Even Wei Chengye and Wu Wenhua were attracted by the noise here and came over to watch the excitement!
  "Would you rather tell me what's the problem?"

At this time, Peng Jun glanced at the people gathered around him and asked more curiously.

"Since Team Leader Peng asked me to talk, I will tell you my opinion~"

Gao Yi is not polite. After all, one more clue means one more way to solve the problem.

So he pointed to the worn spots on both ends of the bottom of the backpack in the photo:
  “The two wear spots are almost the same size, so they are most likely caused by the same object.

Then I noticed this~"

As he said that, Gao Yi took out two more photos, which were detailed pictures of the inside of the backpack. There were two spots of wear on both sides.

It’s just that compared to the wear spots on the bottom, the wear spots on both sides are smaller and crescent-shaped.

"What does this mean?"

Tang Zhengyang looked at the three photos carefully, and finally turned his attention to Gao Yi.

What do four wear points mean?
  "gun."

At this moment, Gao Yi didn't play riddles, and calmly uttered a word.

"gun?"

Everyone was speechless when they heard this.

Peng Jun and Wu Wenhua looked at each other for an instant, and both took a breath!
  Obviously, they understood what Gao Yi meant~
  "Yes."

At this time, Gao Yi nodded affirmatively:
  "Pay attention to the bottom. The worn area is long and slightly curved.

Look at the wear on the side, forming a crescent.

If you guessed correctly, it should be a shotgun with the tip of the gun pointing upward and the butt of the gun downward. "

As he spoke, Gao Yi gestured with his hand: "The length is about 70-80 centimeters. The murderer used this backpack for a long time, and signs of wear will naturally appear over time."

"This……"

Listening to Gao Yi's analysis, everyone felt incredible.

"Can you tell it's a gun based on the signs of wear and tear everywhere?"

Suddenly, Wei Chengye, who had been beside him, touched his chin and asked.

It could also be wear and tear on other items.

Why are you so sure it's a gun?
  At this time, Gao Yi shook his head:
  "With four wear spots, we can't tell it's a gun, but look carefully at the wear spots on both sides and pay attention to the black particles~"

"Black particles?"

Tang Zhengyang took the photo and looked for it: "Where is it?"

"Is this it?" Sun Youmeng on the side squinted his eyes and finally saw a few sporadic black spots.

Really, if you don’t look carefully and carefully, you wouldn’t even dare to say that they are particles!

"Are this boy's eyes magnifying glasses?"

At this moment, even Peng Jun couldn't help but complain.

No wonder Gao Yi kept staring at the photo. Just a few black spots would be ignored even if you pay attention.

So subtle!

After sighing with emotion, Peng Jun looked at the attending forensic doctor Chen Huimin: "Forensic doctor Chen, please do a detailed inspection of the backpack again!"

"it is good!"

Chen Huimin responded immediately.

If the particles are detected to be gunpowder residue, it means that the murderer is likely to have a shotgun.

This is definitely a major discovery!

"Not bad!"

Wei Chengye nodded with satisfaction, then looked at Peng Jun and Wu Wenhua:

"How about it? Are you satisfied with the person I found for you?"

"Satisfied, satisfied!"

Peng Jun was smooth in dealing with things. Hearing this, he immediately smiled and nodded: "The person Captain Wei has found for us is definitely the right one!"

"He carries a shotgun, has experience in butchering, may have cats at home, has regular items in his life, and is from around Hengqiao Road~" Wu Wenhua once again integrated the characteristics of the murderer at this moment.

Just having a shotgun can greatly reduce their search workload. Peng Jun nodded and asked again: "Are there any questions now?"

"No problem." Gao Yi and others responded.

"Okay!" Peng Jun straightened up, looked at everyone with sharp eyes, and shouted in a low voice: "Action!"

……

Fifteen minutes later, Gao Yi, Peng Jun, Tang Zhengyang, Sun Youmeng and others arrived at Huai University.

"Zhengyang, go and get all the surveillance of Huai University for the past ten days. I want the exact information about where Diao Aiqing went to Huai University during this time!"

Peng Jun gave the order.

"Yes!" Tang Zhengyang responded solemnly.

"Gao Yi, Mengmeng, you two go to Diao Aiqing's class and learn about the situation from classmate Diao. You must be precise about what Diao did every day before he disappeared."

"it is good."

Gao Yi and Sun Youmeng nodded.

"Go."

Peng Jun waved his hand.

He needed information about Diao Aiqing's latest news at school.

So Peng Jun stopped wasting time and went straight to the counselor's office.

On the other side, Gao Yi and Sun Youmeng came downstairs to the freshman girls dormitory.

As the final exam is approaching, school classes have been suspended, leaving a week for students to review.

Many universities have such regulations.

So most of the students are in the dormitories at the moment.

"Hello, detective from the Serious Crime Division of our Criminal Investigation Detachment. This is my ID."

At the door of the dormitory, Sun Youmeng found the dormitory manager, immediately showed his ID, and then pointed to Gao Yi: "This is my colleague."

Gao Yi also took out his ID and showed it to the dormitory manager.

"Ouch~" The dormitory aunt obviously didn't expect that one day she would meet the criminal police. She said "Ouch~" and asked quickly: "Crime team... why are you here?

What happened? "

Seeing the excited look in the dormitory aunt's eyes, Sun Youmeng smiled bitterly and then said, "Please check which dormitory Diao Aiqing from Computer Class 1 lives in."

"Okay, wait a moment."

The dormitory aunt looked at Sun Youmeng and Gao Yi while getting the roster, and quickly found Diao Aiqing: "Live in 308."

Immediately afterwards, the aunt added: "But she moved out a week ago and hasn't come back recently."

"Moving outside?"

This news shocked Gao Yi, and he immediately asked: "Do you know the reason?"

"Oh, girls have so many things to do together!

No, a week ago, on the day they suspended classes for review, the school organized a dormitory check, and high-power electrical appliances were found in dormitory 308.

Diao Aiqing was the dormitory director at the time, so she was also responsible for this incident. In the end, she got angry and applied with the counselor to move out of the dormitory and rent a house outside. "

"That seems to be the case." At the end of the sentence, the dormitory aunt scratched her head unsurely.

"Okay." Sun Youmeng nodded with a sweet smile: "Thank you for the clues you provided."

"It seems that the reason why Diao Aiqing's disappearance was not reported has been found."

On the way to 308, Sun Youmeng said to Gao Yi.

"Seven days, that is to say, Diao met the murderer one or two days after leaving school." Gao Yi hummed and quickly sorted out the timeline in his mind.

Seven days ago, on June 6, Diao Aiqing moved out of the school dormitory.

Five days ago, around June 6, Diao was quartered.

There was a gap of two days.

It seems that these two days are the key to solving this case.

What did Diao Aiqing do these two days?
  Also, he was punished during the inspection and moved out of the dormitory on the same day. Is Diao Aiqing so efficient?
  Or is there another secret behind renting a house outside?
  As the timeline was sorted out, questions began to emerge in Gao Yi's mind.

Finally, Gao Yi came to Dormitory 308 with these questions.

Although it is already past eight o'clock, most of the students in the dormitory are still in bed.

Gao Yi glanced at the eight-person room with bunk beds.

The upper bunk near the door was empty, and there were a lot of sundries piled on it.

There is a girl lying on the lower bunk, watching MP4.

On the opposite bunk bed, two girls were also lying, one reading a book and the other listening to music.

Walking inside, there are four beds, but there are only two people, one is reading on the desk and the other is sleeping.

Two more are missing.

"Is there a problem?"

At this time, the girl on the lower bunk at the door saw Gao Yi and Sun Youmeng, especially the police uniforms they were wearing, and immediately sat up from the bed.

Her words also attracted the attention of other classmates in the dormitory, and they all looked at the door for a while.

"police?"

"what happened?"

"Who was cheated? Or who committed the crime?"

……

As students, they rarely come into contact with the police, let alone two of them, so they immediately became nervous.

Fortunately, Sun Youmeng stood up and reassured everyone with a smile:

"Don't be nervous, we are just here to understand some situations."

After saying that, Sun Youmeng walked into the house and asked, "Do you know Diao Aiqing?"

Gao Yi took out the photo and showed it in front of everyone: "That's the person in the photo."

"We know each other!"

It was the girl at the door who nodded immediately after seeing the photo: "What's wrong? Did Ai Qing make any mistake?"

"She made no mistake."

Sun Youmeng shook his head and asked the girl who spoke in a calm tone:
  "Do you know where she is?"

[As expected of a member of the Crime Squad, he has some skills]

On the side, Gao Yi looked at Sun Youmeng who was asking, and secretly approved in his heart.

This kind of criminal investigation officer obviously knows what method and tone of voice to use to interview the most efficient person.

Just like now, when facing these students who have never been exposed to society, you can't be serious and gruff when you come up.

This will make them nervous and prone to forgetting details.

At this moment, Sun Youmeng was handling it very well, her voice was gentle and calm, as if she were chatting.

In this context, the person being asked will be willing to chat with you.

Easier access to useful information.

"I don't know." The girl shook her head and said:
  "She hasn't been back since the last time she moved out of the dormitory."

"Yeah, it's been more than seven days and I haven't answered the phone!" At this time, a girl with a ponytail echoed.

seven days?

Not answering the phone?
  Sun Youmeng glanced at Gao Yi, and then immediately asked: "There has been no news for seven days, why didn't you call the police?"
