Chapter 136 Re-entering the scene
Gu Nankai frowned slightly and looked at Shang Lu: "Hydrogen sulfide poisoning?"
Shang Lu nodded first, then shook his head uncertainly: "It is very likely hydrogen sulfide, but it is just my guess. However, based on the pungent smell we smelled, it shouldn't appear in that place, so I think so."
Gu Nankai thought about it, he tilted his head back and took a sip of water, then looked at Cao Cang: "Cao Cang, was the bathroom door open normally at that time?"
"Not really." Cao Cang shook his head, and Li Meng quickly took over his words: "I helped Cao Cang at that time."
Cao Cang nodded quickly: "Yes, the door was a little difficult to open at first, but it seemed to be just blocked or something, so Li Meng helped me push it from behind, and I used some strength to open it. It wasn't difficult at all, maybe it was just rusty."
Gu Nankai listened to Cao Cang's words and thought for a while, then he said: "So it is certain that the door can be opened, it just requires a little force, right?"
Cao Cang and Li Meng both hummed.
Gu Nankai quickly found the loophole: "So, if a person is not locked up there, why doesn't he come out?"
He thought for a moment and said, "Shang Lu's statement makes sense. We can even be sure that the murderer died of suffocation due to hydrogen sulfide poisoning. Otherwise, the stench of the corpse alone would not be what we smelled. We can find out by testing it later. I just observed that the door of Chen Hui's bathroom is very tight, and there is no vent in that place. If the smell dissipates randomly, it will be very slow. It can even be said that due to the various conditions in his home, the air circulation is very slow. The murderer seems to have deliberately blocked the bathroom door to cover up the volatilization of the smell. So the murderer wanted to kill the victim through hydrogen sulfide poisoning."
But at the same time, Gu Nankai raised another question that made everyone fall into deep thought: "But if that's the case, why didn't the murderer just close the bathroom door? He didn't seem to be worried about this problem, and based on the condition of the body I saw, the victim didn't fight or struggle."
Shang Lu took a deep breath: "Unless the victim is immobile and cannot pose any other threat to the murderer, the murderer will not be worried that he will come out."
"It's very likely." Gu Nankai nodded, agreeing with Shang Lu's guess.
Yang Dong listened to their analysis back and forth in amazement. Before they had fully examined the body, Gu Nankai and the others had already been able to infer such a brilliant conclusion based on the tiny evidence they had found. This made him deeply aware of his own inadequacies. He secretly thought that if it were him, he would never have thought of these things.
Thinking of this, Yang Dong looked at Gu Nankai with even greater admiration. He was proud from the bottom of his heart that he had such an idol. He was even more proud because one day he would be able to listen to Gu Nankai's analysis of the case at such a close distance. Although it was only a small part, it was enough to benefit him a lot. It also made him realize that even the people around Gu Nankai, he still had to make a lot of efforts to catch up.
It seems that everyone has expertise in their field.
"Okay, let's get ready and go in to take a look." Looking at the time, it had darkened unknowingly, but the number of people watching the excitement around was still the same. Gu Nankai signaled everyone to enter the crime scene again.
"Captain Gu!" Yang Dong suddenly called out, and everyone's eyes turned to him.
"Um..." The young man suddenly felt a little insecure, but for what he wanted in his heart, he still mustered up the courage to look at Gu Nankai: "Can I...can I apply...to work on the case with you..."
Hearing this guy say this, Gu Nankai looked at him, and his heart was slightly touched by the hopeful and excited light in his eyes. Wu Qingluan and others also looked at Gu Nankai. Yang Dong had helped them many times when they needed help, and today he saved everyone from danger. In their opinion, Yang Dong's request was not excessive, and Gu Nankai should agree to it.
Everyone thought so, but Gu Nankai's next answer surprised everyone.
"No, you can't go in." Gu Nankai said this to Yang Dong, which made Yang Dong's face change in an instant. He looked at Gu Nankai disappointed and hurt, and asked with some stammering: "I... am I not qualified..."
Everyone felt that there was no need for Gu Nankai to let a child suffer such a blow.
Gu Nankai seemed to know what everyone was thinking. After Yang Dong asked this question, he chuckled and quickly shook his head: "It's not that you are not qualified, it's that this scene is not suitable for you to enter."
He pointed at Cao Cang, Li Meng and the others, and quickly said, "Your senior brothers and sisters have seen too many corpses, so they can ensure that their psychology is not greatly affected. You are still young, and you should not face such a damaged corpse as soon as you get involved in a case. This will have an impact on your future case handling. Everything has a gradual process. Do you remember what I told you when we first met? Some things can't be rushed. You are still young, and you need to take your time."
Seeing the boy's expression gradually changing, Gu Nankai patted his shoulder and said, "I didn't let you enter the scene to protect you, so that you can better face every case in the future. At the same time, I also tell you that for this case, in addition to not being able to enter the scene, I can let you listen in on our subsequent case-solving process."
"Really?" Hearing Gu Nankai's words, Yang Dong's eyes lit up as if stars were coming out.
"Really? So now you still need to assist our teacher Wu and work with her to get more clues from the onlookers so that we can understand Chen Hui from many aspects. I believe you can definitely do this."
After hearing this, everyone understood Gu Nankai's considerations. They had not expected that Gu Nankai had such considerations as to why he did not agree to let Yang Dong go in with them, and their thoughts at the time seemed a little narrow-minded.
Yang Dong was extremely excited to be able to participate in it. He didn't know what prize he had won to be able to receive such teaching from Gu Nankai. He looked at Gu Nankai and nodded his head excitedly and solemnly.
"Okay, except for Teacher Wu and Yang Dong who stay outside, the rest of you follow me into the scene." Everything was arranged, and Gu Nankai called on the remaining few people to follow him into the core scene of the crime again.
"Based on the conditions at the scene, everyone should quickly carry out the evidence collection work." After entering, Gu Nankai gave everyone an instruction that for safety reasons, everyone should still wear masks on their faces.
Shang Lu did not focus his attention on the corpse in the living room again.
"Boss! Let's go to the bathroom!" She said to Gu Nankai. Putting aside her initial shock, for a forensic doctor, she felt eager to try when she saw such a corpse. This should be a rare type of corpse she had ever encountered. However, the bathroom was too cramped, and probably only two people could complete the evidence collection work.
Gu Nankai originally didn't want to let Shang Lu enter the bathroom because of her gender, but Shang Lu was the most suitable person to go in. Now that she said that, Gu Nankai thought about it, and Shang Lu gestured to her and said, "I'm not afraid! Don't worry! It's safer if I go in! Come with me!"
Thinking that what Shang Lu said made sense, Gu Nankai finally nodded.
