Chapter 6 The Second Case Gray Scientific Research (4)

The isolation belt at the crime scene has not yet been removed. The security guard who reported the crime warmly received Huang Yiwei and his party. The security guard said: "The school will start soon. I didn't expect such a thing. The school asked the security guards to increase the number of patrols. I hope

Please solve the case as soon as possible."

Huang Yiwei responded: "Yes, solve the case as soon as possible. Are we here again?"

The security guard said with emotion: "What a pity, he is still a doctor!"

Huang Yiwei was surprised: "How do you know she is a doctor? Do you know her?"

The security guard flashed a hint of panic: "I don't know him. I am a security guard and he is a doctor. How can I know him? I saw it on the Internet."

Huang Yiwei saw his panic and asked casually: "Really? I haven't seen the news on the Internet. Where did you read it? Tell me."

The security guard obviously did not think that Huang Yiwei would do this. He hesitated, took out his mobile phone, and searched for a long time before finding news about the Tianyang University female corpse case on a certain website. After taking his mobile phone, Huang

Yiwei read the news from beginning to end and found that the whole article did not mention that the deceased was a doctor, only that he was a college student. Huang Yiwei calmly returned the phone to the security guard: "Go and do your work.

If necessary, we will come back to you." The security guard took the phone and left.

Captain Yan, who was traveling with him, understood the situation and immediately took people to check the security guard's identity information and search the security guard's dormitory. Huang Yiwei continued to lead the technical investigation team to re-examine the scene. Others searched for suspicious traces at the scene, and Huang Yiwei

Yiwei stood behind the tree where the murderer was hiding, deducing the murderer's crime process. He thought

: "The deceased separated from her boyfriend, entered the school alone, and walked back to the dormitory through the tree-lined shortcut. The murderer hid behind a tree and waited for the deceased, indicating that the murderer was familiar with the deceased's habits. It is during the summer vacation, and there are few people here around 0:00 in the morning. Why did the murderer

Not immediately, but at 1 o'clock in the morning

Where to start? They were acquaintances, they must have talked, and the last words did not agree, and the murderer finally killed the deceased. But how did the murderer come in and out? Why didn't the murderer come in and out from the south or west exit, which is the only exit of the boulevard. If

You didn't go out through the exit. You must have crossed the holly before going out.

Yes, after leaving the woods, you still need a door or exit to escape. The cameras in the library and the surveillance at the entrance of the South School of Chemical Engineering did not capture anyone leaving. This shows that if you want to escape, the murderer should have other exits, otherwise he has no choice but to

Climb over the wall, this may be the place that was missed in the last survey."

Thinking of this, Huang Yiwei walked towards the gap between the hollies on the east side of the woods. He came out of the woods and saw the east wall. He had seen it last time. He checked it carefully to confirm that there were no signs of climbing. He saw it again.

Under the wall, there are some large display racks used for school promotion, with content such as "Welcome New Students" written on them.

Just when Huang Yiwei was fascinated, a puppy suddenly emerged from behind the promotional page. At the same time, he heard a cry outside the wall, as if saying "Nini". Huang Yiwei suddenly understood something, he

He picked up the puppy and walked along the fence to the school gate. He walked to the old lady outside the fence who was calling for the puppy and handed the dog to the old lady.

Sure enough, there is a small door made of welded steel pipes, and the puppy entered the school through here. The steel pipes are covered with rust, and traces of rust being rubbed away were found between two of the steel pipes. Someone may have been in and out here.

The scratched mark is about 70 centimeters long from top to bottom, and the highest point is about 1.45-1.5 meters, indicating the height of the person.

Not high. Huang Yiwei tried it, and found that the gap in the steel pipe was big enough for his head to get through. Generally speaking, if the head can go through, the body can go through. Pi Peng took a photo, and Dai Jiaxing called the security captain. Huang Yiwei took a picture.

Pi Peng pointed over his shoulder at the camera at the door of the small hotel outside the east wall of the school. Pi Peng immediately understood what Huang Yiwei meant and walked towards the small hotel.

The security captain said: "This small gate is at least ten years old. At that time, the school's gate was closed at 12:00 at night, leaving only this small gate for entry and exit. This small gate could accommodate at most one person riding a bicycle. Later, the gate was rebuilt.

Now, the road has been widened, cameras and landing gear have been installed, and the door is no longer closed at night. This small door has been abandoned and has not been used for many years, so some promotional shelves are often placed next to the wall.

."

Speaking of this, the security captain suddenly remembered something, "One thing is very strange. After my shift yesterday morning, I found that the advertising page had been moved away. I spent a long time sorting it out."

Pi Peng said angrily: "Who asked you to tidy it up?"

The security captain was startled and explained: "If we don't tidy things up, the leader will curse again."

Huang Yiwei hurriedly advised Pi Peng: "You are not wrong. We sorted it out when we came here yesterday. You can try again and see if you can extract any useful clues."

Pi Peng was obviously very upset and didn't say anything. He was busy minding his own business. Now it seems that the murderer entered and exited the crime scene through this abandoned door, so the campus surveillance did not capture him. This shows that the murderer is very

If you are familiar with the environment around the school, you are likely to be someone from the school.

Team Yan found out that the security guard who reported the case was named Fan Ruojun, 22 years old. In the closet of Fan Ruojun's dormitory, only some personal items were found, mainly clothes, books, fitness cards, and an eagle-bill knife. There was a set of "I am

"Special Forces" series of novels, there is a pair of Martin boots under the bed. It seems that Fan Ruojun is a military fan. No relevant clues were found.

Just when everyone was about to go back, Captain Yan received a call from Li Jianqiang: "Captain Yan, Peng Ying checked the surveillance and saw that at 11:05 yesterday morning, a security guard walked into the south entrance of the boulevard. At 11:07, the security guard held a black

bag, came out of the south exit of the boulevard, and then walked east toward the security dormitory. Intel did image processing and it was the security guard who reported the crime. There must be something wrong with him."

After hearing this, Captain Yan immediately asked everyone to search Fan Ruojun's belongings again, but still found nothing. The knife was not the murder weapon, and there was nothing suspicious about the other parts. Yan Gang thought about it, and finally his eyes fell on the fitness card.

on.He picked up the card

It said "Landao Fitness Club" on the top and the membership card number on the bottom. Turning to the back, he found the four numbers 7458. Team Yan decided to go to the Blue Island Fitness Club to have a look and called Tan Hailong. Ling Shuang also wanted to

Go. Captain Yan stopped her, but Ling Shuang was not convinced.

Captain Yan told her: "We are going to the men's locker room in the gym, do you still want to go?" Ling Shuang stopped talking, and Captain Yan asked her to stay and help Huang Yiwei.

Captain Yan and Tan Hailong arrived at the Blue Island Fitness Club and learned from the front desk that the card was a VIP card. The closet is fixed and can only be opened by guests holding the card. The number on the back is the number of the closet. Sure enough, Captain Yan was in the closet.

The deceased’s mobile phone and shoulder bag were found inside

Bao. Team Yan immediately called Ling Shuang and asked her to find Fan Ruojun and keep an eye on him. At the same time, he notified Li Jianqiang and Han Wenjun to immediately meet up with Ling Shuang and arrest Fan Ruojun. After they met, they took Fan Ruojun away from the Tianyang University concierge.

, he made no resistance.

In the interrogation room, Fan Ruojun sat opposite Li Jianqiang and Han Wenjun, and Yan Gang sat in the observation room next door.

The interrogation is ongoing.

"I am calling the police, why are you arresting me? I have been cooperating with you to solve the case, but you are too careless!" Fan Ruojun complained.

"Stop talking nonsense! I asked you what to say. Let me show you a video." Li Jianruo motioned to Han Wenjun, "Xiao Han, play it for a moment."

The TV showed a video of Fan Ruojun walking out of the boulevard with a black satchel. After watching the video, he immediately became honest.

He said: "That day, I went on patrol with the captain as usual. I found a black satchel on the avenue. I looked inside the holly and saw a few pieces of paper scattered in the middle of the grass. I walked around the holly and found the body. I was scared at the time.

, I don’t know what to do. After calming down for a while, I know that the surveillance camera cannot capture the inside of the boulevard.

I wanted to check if there was any money in the bag, but I heard the captain calling my name. I hid the bag in the holly bushes in a hurry, then called the captain, and finally reported the crime. I just wanted to get some money to replenish my life.

VIP fitness card, I didn’t expect——” As he said, he started crying, “you guys would find out so soon.”

"Look at how bad you are?" Li Jianqiang couldn't help but laugh, "Why do you put the deceased's belongings in the gym?"

"The gym is safer than the dormitory and is less likely to be discovered." Fan Ruojun said with a sad face.

Li Jianqiang asked: "Why don't you throw away the bag?"

He said frustratedly: "There was no money in the bag, only a few bank cards, credit cards and so on. I didn't know the password, and I didn't dare to withdraw the money. I just thought about whether I could sell the bag for some money, so I kept it and returned it.

There was no time—and then here we are.”

Li Jianqiang asked: "Do you know the deceased?"

He shook his head: "I don't know, I am just a security guard, and he is a doctor."

Li Jianqiang slammed the table hard: "How dare you lie! If you don't know her, how do you know she is a doctor?"

He plausibly said: "There is news on the Internet, I have read it."

"We have seen the news you pulled out, and it did not mention that the deceased was a doctor at all." Li Jianqiang slammed the table again, startling Fan Ruojun, and said sharply: "Tell me, how did you kill the victim?

"

Fan Ruojun cried again: "I don't know her, why should I kill her? During the epidemic, you have to check your student ID card when coming in and out. I have seen her student ID card. She is a doctor. I have never seen anyone with such a high degree of education, so I just remembered it."

Live."

After hearing this, Li Jianqiang felt that the reason was reasonable, so he said nothing more. Captain Yan used the microphone to remind him that what Fan Ruojun said should be true. He was on duty during the time of the crime, so he could end the interrogation and release the person.

In the office, Huang Yiwei, Pi Peng, Peng Ying, and Dai Jiaxing sat around the computer and looked at the surveillance videos collected from the investigation and visits, including the street directly opposite the door and the surveillance videos at the door of the small hotel outside the east wall of Tianyang University. Peng Ying

A video was quickly found of the deceased's boyfriend Wang Zhili entering the car and driving away. The departure time was 00:05 midnight.

According to the city's Sky Eye system's vehicle tracking survey, Wang Zhili arrived at a bar at 00:35. The waiter at the bar confirmed that Wang Zhili stayed until the bar closed at 2:00 in the morning. He seemed very happy and gave each table a drink.

A bottle of wine. Consistent with Wang Zhili’s confession, Wang Zhili had no time and motive to commit the crime, so suspicion can be ruled out.

Playing the surveillance video at the entrance of the small hotel outside the east wall of Tianyang University, Peng Ying directly increased the video playback speed to 16 times.

Dai Jiaxing complained: "Intel, are you crazy? Who can see clearly so quickly?" Pi Peng looked elsewhere, his eyes dazzled.

Peng Ying said calmly: "I can see it clearly. Such a video can be viewed at 16x speed."

Dai Jiaxing was still reluctant: "What do you mean you can watch a video like this at 16x speed? Are you saying I have a low IQ?" He wanted to say something else, but found Huang Yiwei staring at him and said nothing more.

Huang Yiwei said: "You really don't have any IQ when watching the surveillance video. The picture was taken in the early morning, and there were few people on the street. Viewing it this way can improve efficiency, and Peng Ying often watches the surveillance video, so he is more efficient than others in identification.

Yes, it's completely understandable. What do you think?" Dai Jiaxing was obviously convinced and couldn't say anything.

At this moment, I suddenly heard Peng Ying shout: "Boss, we found it."

Everyone looked at the computer screen. Peng Ying had adjusted the screen to normal speed. In the upper right corner of the screen, a person came out of an abandoned door. He was wearing a peaked cap, a long-sleeved shirt, trousers, and white shoes.

He walked from the far end of the screen to the door of the hotel, and then disappeared from the screen. The video pixels were good and had been processed clearly. The person in the screen was wearing a mask, and there seemed to be something on the mask.

Some patterns or patterns. The video was taken at night, and the color of the clothes is not easy to distinguish. The strange thing is that the road is clearly on the right side at the bottom of the picture, but he walked straight to the door of the hotel. Did he stay in the hotel? Huang Yiwei asked.
