Chapter 233 One
After she finished speaking, she immediately ran towards Gu Nankai and the others. When she got there, she found that several people were staring in the same direction. She followed their gaze and frowned, "This is..."
“
As soon as he finished speaking, Gu Nankai immediately responded. As soon as he finished speaking, everyone looked at him with a hint of teasing in their eyes. Gu Nankai rolled his eyes and woke them up helplessly: "What are you thinking about? You can't pretend to be innocent at this time."
"Boss, don't be so blunt. I'm still a young man, pure and innocent."
Gao Yuan chuckled. Cao Cang had already stepped forward and put the thing stuck to the trash can into the evidence bag. At the same time, Gu Nankai rolled his eyes at Gao Yuan and turned around and said, "The victim may have been sexually assaulted before his death. Go back and check the contents carefully."
"Boss, I understand."
Cao Cang nodded and said, "Boss, the reason why the victim was killed was because he was sexually assaulted?"
He obviously felt that this possibility was not true, and his eyes were full of doubt. At the same time, Gu Nankai also said, "This possibility is not impossible, but why did they cut off the victim's feet? This is obviously not worth the loss for a murderer who has chosen to corrode the victim's body. Since the murderer has chosen to corrode the victim's body, it means that cutting off the victim's feet was not to cover up her identity. We need to investigate the motive behind this."
Gu Nan's analysis made everyone feel that this matter was not that simple. Several people's faces changed and became very solemn. Thinking of this, Gu Nankai quickly assigned tasks: "Everyone look around to see if you can find some clues. I'll go to Shanglu to check the condition of the body."
Wu Qingluan didn't dare to follow, so she hurriedly pulled Cao Cang away and said, "Cao Cang, I'm in your group, let's go and look for it quickly."
Gao Yuan and Li Meng looked at each other, smiled, and dispersed to look for clues.
Gu Nankai quickly returned to Shang Lu, squatted down and asked, "How is it, did you find anything?"
Shang Lu raised his eyebrows, exhaled, turned his head to look at Gu Nankai, and answered his question at the same time: "What caused the corpse to rot was a highly corrosive strong acid, which is what we often call 'aqua regia'."
She then clicked her tongue twice: "To destroy the body in such a cruel and horrible way, how much does this murderer hate the victim."
Gu Nankai added at the right time: "We just found a rifle and suspect that the victim may have been sexually assaulted before his death."
"Sexual assault?"
This surprised Shang Lu a little. He frowned and looked at Gu Nankai: "A tragedy caused by unrequited love?"
Gu Nankai shook his head uncertainly: "It's not certain yet, but I can't rule out this possibility, and it's a relatively high possibility."
Shang Lu sighed, he simply couldn't understand why there would be such a person. If you can't get someone, you have to destroy that person? Not only destroying someone, but also leaving their body mutilated, what kind of pervert could do such a thing.
"Okay, let's not talk about this for now. Can the cause of death be determined?" Gu Nankai pondered for a moment, then immediately came to his senses and asked Shang Lu again.
Shang Lu shook his head in embarrassment. "It's still unclear. The body is almost reduced to bones under the effect of strong acid. It's hard for me to determine how the victim died. Maybe she was sexually assaulted and fell into a coma, and then was killed by the killer's strong acid. Or maybe she was already dead before she was corroded. Or there may be other ways of death that I haven't thought of. The conditions at the scene are too simple. If you want to know more, you have to talk to the serious crime team first."
Gu Nankai looked at the mutilated body, sighed, nodded, and said, "Looking at the current situation, I'm afraid it will be difficult to determine the identity of the victim for the time being."
Shang Lu also looked at the body and nodded, and then she pointed to the position above the body and said, "Boss, look at this air conditioner."
Gu Nankai's eyes quickly moved over. There was an air conditioner on the body, which was good. This was understandable for a laboratory . What was Shang Lu's intention in letting him look at this? He narrowed his eyes with a sharp light. Soon, he looked at Shang Lu with bright eyes: "You mean, the murderer tried to stuff the body into this air conditioner to hide the scene?"
"That's right." Shang Lu nodded. " But the air conditioner is too small, and the body can't be stuffed in. That's why the murderer chose to use strong acid to corrode it. Obviously, the murderer doesn't want everyone to know the identity of the victim."
Gu Nankai thought for a moment with a serious look in his eyes, and then said, "Moreover, it is difficult for ordinary people to come into contact with aqua regia. Aqua regia is a liquid that is particularly easy to deteriorate, and it must be prepared and used immediately. This requires certain chemical knowledge and the ability to operate relevant measures. In addition, the aqua regia that can corrode the victim's entire body must be prepared. Could the murderer be a chemistry student?"
"I think so too. You see, this laboratory is very familiar to the students of the Department of Biochemistry. It would be very convenient for them to do something here." Shang Lu nodded repeatedly and responded to Gu Nankai's words.
Gu Nankai's eyes darkened again and he said, "And according to my observation, the surveillance camera outside this laboratory seems to have been removed recently."
Shang Lu's eyes glared like two big copper bells, and he rolled his eyeballs a few times and said immediately: "With the right time, right place and right people, who can stop you from doing something bad!"
Isn't it? Gu Nankai took a deep breath, and his thoughts were the same as Shang Lu's. Such a hidden and safe crime scene was simply a paradise for the murderer, allowing him to carry out the murder smoothly.
Thinking of this, Gu Nankai seemed to have thought of something else: "Take a look at the body to see if there are any traces of aqua regia at the laboratory site."
Shang Lu nodded quickly and focused his attention on the corpse again, and Gu Nankai stood up to verify his previous thoughts.
The laboratory was quite large. In order to quickly confirm his idea, Gu Nankai called Cao Cang to check with him. When the two met, Gao Yuan shook his head and said, "Boss, there is no trace of aqua regia in this laboratory."
Gu Nankai also nodded solemnly, "Indeed, I didn't find any traces in any of the facilities. I just asked Zhang Quan, and he said that the experimental materials used in the laboratory need to be applied for in advance and sent to each class in a certain quantity. They need to prepare enough aqua regia to corrode the entire corpse. If this happened, the school would have discovered it long ago."
"In other words, the murderer most likely got the materials from outside?" Gao Yuan no longer looked nonchalant, and looked at Gu Nankai very seriously.
Gu Nankai nodded solemnly: "If Zhang Quan's statement is correct, and there is no problem with the school, then the only possibility you mentioned is this."
"Oh my God, the murderer had been planning to kill the victim for a long time." Gao Yuan exclaimed, looking at Gu Nankai with some fear.
Gu Nankai's face was solemn. At this moment, Shang Lu called out to Gu Nankai: "Boss, come and take a look!"
The voice was filled with surprise. Gu Nankai's face changed and he patted Gao Yuan and immediately turned around to go to Shang Lu.
"What did you find?"
As soon as he arrived, he asked Shang Lu directly. Shang Lu asked him to look at the victim's head. He immediately squatted down to look. He actually found something and a hint of joy appeared on his face. Everyone had been searching for a long time without finding anything valuable, but now they finally made a discovery.
