When the police car stopped at the gate of Nanshan Laboratory, a young man in casual clothes quickly opened the iron door and took the initiative to greet him.
"Comrade police, you are here."
"What happened?" Gu Chen got out of the car first, turned on the law enforcement recorder he carried with him, and asked him: "Did you call the police?"
"Yes...yes." The young man nodded quickly and explained: "Yes...I called the police."
"The alarm center said there was an explosion in your laboratory. What happened?" Lu Weiwei, who then walked to Gu Chen's side, also quickly arranged her hair and put her police hat on her head.
The young man shook his head. He was extremely nervous and felt extremely frightened.
Gu Chen took out his notebook and asked him calmly: "Don't be nervous. Tell me slowly what happened here."
"It's my fault." The young man lowered his head and said regretfully: "Gao Cheng and I were originally on duty tonight, but I didn't know that something like this would happen. The laboratory exploded and Gao Cheng was seriously injured, but I was not with him.
, Gao Cheng might die."
Seeing the remorseful look on the young man's face, Gu Chen and Lu Weiwei looked at each other, wondering what happened in the laboratory?
So Gu Chen asked again: "Was Gao Cheng the only one in the laboratory at that time? Is there only one person on duty in your laboratory at night?"
"That's right." The young man said with a sad face and nodded repeatedly: "Originally, Gao Cheng and I were on duty together, but I was temporarily called out for dinner by my colleagues."
"At that time, I thought that with Gao Cheng in the laboratory, there would be no problem. But when I returned to the laboratory, Gao Cheng had fallen into a pool of blood, with glass shards everywhere on his body, and he had fainted.
Already."
"When I arrived, Gao Cheng seemed to be almost out of breath. I quickly called 120. Just before you arrived, Gao Cheng had just been sent to the hospital."
After saying this, the young man wiped his tears again.
Gu Chen wasn't very clear about the situation at the scene and couldn't make a conclusion, so he had to go to the laboratory to have a look, so he asked the young man: "What's your name?"
"My name is Liao Feng, and Gao Cheng and I are both Professor Zhang's assistants."
"Okay Liao Feng, since Gao Cheng has been sent to the emergency room, can you please take us to the laboratory to have a look?" Gu Chen said.
Liao Feng did not hesitate, and directly gave up his position and said: "Then you all come with me, I will take you there."
Following Liao Feng's footsteps, everyone walked through an office building and arrived at a shorter building at the back of the office building.
"This is our laboratory." Liao Feng turned around and introduced it to everyone.
At this moment, he quickly took out the key and opened the laboratory door.
As soon as he stepped into the door of the laboratory, Gu Chen found that the ground was full of glass residue and various fragments were scattered on the ground.
When you step on it with the sole of your shoe, it will make a "crunching" sound from time to time.
"Wait a minute." Officer Wang stopped advancing and said to Liao Feng: "Who else has come in here besides you?"
"Is there no one? I'm not sure."
"You don't know?" Gu Chen frowned and asked again: "When you left the laboratory, the door was not closed, right?"
"Yes." Liao Feng did not deny it, but directly explained the situation to Gu Chen: "Because we were on duty that night, I was called out to eat temporarily, so the laboratory was not closed. I don't know who came in.
Clear."
"But judging from the situation at the scene, I don't know what happened, because there were many broken glass fragments on the floor of the laboratory."
As if he thought of something, Liao Feng added: "Oh, by the way, there is also a stone with a diameter of about 18 centimeters."
After saying this, Liao Feng noticed the stone at his feet and was about to bend down to pick it up.
"Wait a minute." Gu Chen pulled him back and reminded: "Don't move, leave this to us."
"Ah?" Liao Feng didn't seem to understand. He was stunned for a moment. He didn't react until he saw Gu Chen put on white gloves.
Gu Chen first held the big stone in his hand and weighed it, then turned to ask Liao Feng: "Does this stone already exist in your laboratory?"
"No, I haven't seen it either." Liao Feng said this, and suddenly hesitated, so he added: "Although I haven't seen it, this stone may be in the laboratory, but I didn't notice it myself."
"Then have you ever touched it?" Seeing that Liao Feng was preparing to lift the stone with his bare hands, Lu Weiwei couldn't help but ask.
Liao Feng continued to shake his head: "I haven't touched it before. I just thought it was strange. After all, how could there be such a large stone in this laboratory?"
"I don't know who brought it in, because when I came back from dinner, I found Gao Cheng lying on the ground with a lot of broken glass in his face and chest, and his body was covered in blood."
"Then I found this big stone on the floor. I felt that Gao Cheng must have been attacked, so I quickly called the police after making the emergency call."
"Wait a minute." Gu Chen interrupted Liao Feng's words and asked him: "How can you be sure that Gaocheng must have been attacked by someone and not some dangerous items in your laboratory that exploded?"
"Impossible, absolutely impossible." Liao Feng directly denied Gu Chen's remarks and said: "We know very well that there are no dangerous items in this laboratory."
"There was no dangerous nitroglycerin, no gunpowder, and no traces of burning. However, the situation at the scene was obviously caused by an explosion. But where did the explosion come from?"
Liao Feng kept asking questions, which made Gu Chen unable to answer for a while. He could only say calmly: "Don't get excited. Let me see the scene first. Please retreat to the door first and don't destroy the scene."
"Okay... okay." When Gao Cheng saw Gu Chen, Lu Weiwei and Officer Wang all starting to put on foot gloves, he consciously retreated to the door in order not to cause trouble for everyone.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! At this moment, Gu Chen, Lu Weiwei, and Officer Wang also began to investigate the scene.
Not only were glass fragments scattered everywhere on the ground, Gu Chen, who had a sharp eye, even found a broken glass bottle cap in a corner with several knotted metal wires tied to it.
Gu Chen picked up the glass bottle cap and put the metal wire in his hand to observe carefully.
"What is this?" Lu Weiwei also noticed it and hurriedly walked to Gu Chen and knelt down to check it out.
"It seems to be piano wire." Gu Chen also frowned. For a while, he couldn't explain why the piano wire in his hand was here and tied with a knot to the glass bottle cap.
Officer Wang came over, stretched out his hand and said, "Show it to me."
Gu Chen handed it over to him and then continued to search other corners of the laboratory, but there seemed to be some doubts in his heart.
"It seems that the explosion was caused by the contents of the glass bottle." Gu Chen looked at the broken glass on the ground and related it to the bottle cap, and he probably made some conclusions of his own.
Gu Chen picked up the fragment of the bottle cap just now, put it to the tip of his nose and smelled it. It seemed to smell of alcohol.
"That's strange." Gu Chen frowned and after looking around, he found that there were no so-called dangerous and flammable items around him.
And it’s the same as what Liao Feng said just now.
"There was no dangerous nitroglycerin, no gunpowder, and no traces of burning." Looking back at the debris on the ground, Gu Chen shook his head slightly: "But how did this explosion occur?"
It seemed that he was also caught up in Liao Feng's doubts just now, but while Gu Chen was thinking about it, he suddenly discovered that a wooden bookshelf seemed to be wet and dripping.
Gu Chen quickly walked to the bookshelf, first used his hand to stir the tip of his nose a few times, and after discovering that the liquid was colorless and odorless, he gently touched the water stain with his hand.
"Isn't this water?" Looking at the wet water stains on the bookshelf, Gu Chen suddenly pondered: "Maybe the glass bottle just now must be filled with water, but water will not explode."
Shaking his head, Gu Chen called Liao Feng to his side again and asked him: "Tell me about your activities tonight, the more detailed the better."
"Yes...it's okay." Liao Feng nodded, and after calming down, he said: "Gao Cheng and I are both assistants to Professor Zhang, and we interned here after graduation. In fact, there are no dangerous items in this laboratory.
, most of them are experimental equipment.”
"Tonight, Professor Zhang originally arranged for me to be on duty with Gao Cheng, but then another colleague of mine called me and asked me to go out for supper together. He said he would pay the bill."
"Of course I was happy when I heard it. After all, I hadn't gone for a late-night snack in a long time. I thought since Gao Cheng was in the lab at that time, everything would be fine, so I went out with another colleague."
"Do you know the approximate time of the explosion?" Gu Chen asked again.
Liao Feng shook his head: "Well, I really don't know. I also returned to the laboratory after eating the midnight snack and saying goodbye to the colleague. It was already quite late at that time, and I only found out that something happened in the laboratory."
"When I saw Gao Cheng lying on the ground, bleeding everywhere, I thought it was some dangerous item exploding in the laboratory."
"But when I think back, it's wrong. There are no dangerous items in our laboratory, but how did Gao Cheng get injured?"
"But it feels like someone attacked him. I don't know what to do, so I called you to help."
"Got it." After Gu Chen looked around the scene, he took photos of the scene to collect evidence. He then collected some bloody glass fragments in an evidence collection bag and prepared to take them back to the technical department for testing by the municipal bureau's technical department.
"Are you ready?" Seeing that Lu Weiwei was still searching, Officer Wang on the side quickly reminded her.
"No dangerous items were found." Lu Weiwei has checked the scene three times. As before, it seems that there are no so-called flammable and explosive items at the scene.
Officer Wang said: "The most important thing now is to see the situation in Gaocheng. Only Gaocheng knows what happened tonight."
"Yes." Gu Chen also crossed his arms and nodded slightly, but he fell into deep thought.
But suddenly, out of the corner of Gu Chen's eyes, he was attracted by a dark shadow at the door.
"Who is it?" Gu Chen immediately turned around and asked.
"I...I am Lao Zhang, the professor here." A middle-aged man wearing a leather jacket was standing at the door anxiously.
"Professor Zhang, Professor Zhang, you are here." Liao Feng saw him and quickly walked to him. Then he introduced to Gu Chen, Lu Weiwei and Officer Wang: "Comrade police, this is Professor Zhang from Nanshan Laboratory.
Gao Cheng and I both work as assistants under him."
"Hello, Professor Zhang." Gu Chen took off his white gloves, shook hands with him and said, "I am Gu Chen from the Criminal Investigation Group Three of the Furong Branch."
"Hello...Hello." Professor Zhang's attention at the moment seemed not to be on Gu Chen at all, but instead focused on the inside of the laboratory.
He was about to lift his legs to enter the door, but was blocked by Gu Chen.
"Professor Zhang, this laboratory is currently under the control of our police until the matter is clarified." Gu Chen told him directly.
Professor Zhang frowned: "But...but what is going on here?"
"Professor Zhang." Seeing that the professor he informed had just arrived, Liao Feng hurriedly reported to him: "Gao Cheng is injured, covered in blood, and there are glass fragments everywhere on his body."
"What about the people in Gaocheng now?" Professor Zhang asked him quickly, feeling extremely nervous.
"He was sent to the hospital. I guess... it's probably a very bad time." After saying this, Liao Feng burst into tears.
Professor Zhang was so anxious that he stamped his feet: "I said Liao Feng, what on earth did you do? I asked you to work the night shift in the laboratory, what on earth did you do here?"
"Professor Zhang, I'm sorry." Liao Feng burst into tears and said with regret: "Originally, I was here to accompany Gao Cheng on duty, but later, Zhang Hao called me and asked me to go out for supper."
"I thought, since Gao Cheng is in the laboratory anyway, nothing will happen, so I went out for supper with Zhang Hao."
"But later, after I said goodbye to Zhang Hao, I returned to the laboratory and found that Gao Cheng had already fallen to the ground, and he seemed to have fainted."
"And the blood on my body was bleeding a lot. I felt that Gao Cheng was about to die, so I quickly called 120 for emergency treatment."
"Then...then what did the doctor say when you sent him to the ambulance?" Professor Zhang suddenly turned blue.
Liao Feng shook his head and kept shaking his head.
Professor Zhang was so angry that he pushed him: "Liao Feng, you should speak quickly."
"The doctor said he... said he might be dangerous."
"What else?" Professor Zhang was so anxious that his neck twisted at 45 degrees, and he looked at Liao Feng without daring to look away for a moment.
"No... no, no." Liao Feng burst into tears and seemed to be in extreme grief.
Professor Zhang was so frightened that he took two steps back and leaned against the wall. His face turned blue and he said, "So, you don't know what happened in this laboratory?"
"I don't know, I really don't know." Liao Feng wiped his tears and said with a choked voice: "If I could come back earlier, I might be able to find out right away that Gao Cheng wouldn't have shed so much blood.
There is no way it could be life-threatening."
"It's all my fault, it's all my fault. I shouldn't have left my post without permission, and I shouldn't have gone out for supper at night. I'm sorry for Gao Cheng, and I'm sorry for him."
"You all calm down first." Seeing that Liao Feng and Professor Zhang were interfering with the investigation by crying, Lu Weiwei came directly to them and said: "We need to temporarily seal off this laboratory, and irrelevant personnel are prohibited from entering or leaving.
, please cooperate.”
"No... no problem." Professor Zhang agreed readily: "This laboratory is for these assistants to do projects and experiments. There is nothing special and valuable in it. You can seal it if you want. But please
You must help us investigate clearly."
"Don't worry about this." After completing the evidence collection work at the scene, Gu Chen came to Professor Zhang and said, "It is our police job to investigate and collect evidence. We will definitely help you find out the cause. We also ask for your Nanshan Laboratory's active cooperation.
."
"That's for sure." Professor Zhang nodded frequently.
"Besides..." Gu Chen looked up at the two of them and asked, "You are the person in charge of this laboratory, right?"
"That's right." Liao Feng nodded.
"Then please fill in your name, ID number and phone number. If there is any latest situation that requires cooperation, our police will contact you in time."
Seeing that the two of them were stunned for a few seconds, Gu Chen asked again: "Any questions?"
"Oh! No... no problem."
"Leave your phone number, right? We'll fill it in."
Also at Gu Chen's prompting, Liao Feng and Professor Zhang respectively filled in their names, phone numbers and ID numbers on the blank pages of the investigation transcript.
Gu Chen closed the notebook and then said: "Seal this place down. In addition, come with us to the hospital to see Gaocheng's current situation."
"Okay, let's go now." Professor Zhang said.
After locking the laboratory, Lu Weiwei also took out the portable cordon from the tool bag and posted it on the door.
A few people then went downstairs and rushed to Gaocheng Emergency Hospital together.
Professor Zhang's car was in front and the police car was behind.
When we arrived at the emergency center, it was already late at night.
At this moment, the lights at the door of the emergency room are still on, and everyone is waiting anxiously at the door.
Looking at the light that was on, everyone hoped that it would go out quickly so that Gao Cheng could come out safely.
At the same time, I was worried that the lights would go out and people would leave, leaving only a body behind.
There weren't many people in the corridor.
Gu Chen, Lu Weiwei and Officer Wang were leaning against the walls on both sides of the corridor, while Professor Zhang and Liao Feng were standing at the door of the emergency room.
It was like the first news coming from the emergency room, both of them were the first to know.
He didn't know how long he had been waiting, but there was a sudden buzzing in Gu Chen's ears, and the light on the door of the emergency room suddenly went out.
At this moment, Professor Zhang and Liao Feng both stood up straight, while Gu Chen, Lu Weiwei and Officer Wang all turned their attention to the door.
It seemed that he was waiting for the doctor who came out first to inform everyone of his death or survival.
"Creak!" The door opened.
As soon as a middle-aged man wearing surgical clothes went out, Liao Feng rushed over and grabbed him with both hands.
"Gao Cheng...is he still alive?"
