Several of us were startled, and Leng Tong hurriedly screwed the lid on, and said with a change in face: "Liquid nitrogen!" ”

"I'll go! I thought the grenade was scared! The big thunder urn shouted angrily, looking really startled: "Leng girl, what the hell is liquid nitrogen?" ”

Only Da Leizi dares to call Leng Tong like that, but Leng Tong doesn't seem to care about him, but Da Leizi's question is also what we want to ask, I have only heard of liquid nitrogen, and I don't know much about it.

"Thanks to me, cover it in time, otherwise your hands will be frozen." Leng Tong glared at Da Leizi, and then said: "This kind of thing is used to make refrigerant, the temperature is extremely low, minus two hundred degrees is its boiling point, let alone room temperature, how can Uncle Li have such a thing?" ”

When I heard the word refrigerant, my heart moved, and I contacted the refrigerator and blurted out: "I thought this refrigerator was a little abrupt just now, could it be used to freeze something?" Maybe it'······"

"Human organs?" Leng Tong's big eyes were already big, but at this time, they were even more round, staring at me for a moment.

I also nodded, realizing that this may be the source of the murder of two people in a row, since this case happened, we have not figured out the motive for the killing, and Professor Li has no enemies, if there are any interests involved, or some kind of crime, it is difficult to say!

"It's very likely that this is the first scene, processed!" Leng Tong immediately said: "And freezing is not just such a thing, there must be other utensils." ”

As soon as the two of us said this, Team Xing's face also changed, and several of us thought almost at the same time that this place where the utensils were loaded might be the place where clues would be found, and everyone walked towards the refrigerator.

I have already looked at the handle just now, there are no fingerprints on it at all, and I opened the refrigerator to look at it, and at this time I came over and looked at it to the side, and this look made me ecstatic - on the right side of the refrigerator, the side piled up against the table and chairs, I can clearly see that there are four fingerprints in the dust!

But this fingerprint is not necessarily left by the murderer, the murderer has dealt with the scene, unless this place is omitted, or it is left by Uncle Li.

I didn't make a sound, and motioned for Leng Tong and Captain Xing to come over, and the two of them came over to take a look, and they both showed surprised looks, but Team Xing soon showed puzzled eyes again.

Leng Tong came over and stood in front of the refrigerator, looked left and right, and stretched out his little hand to gesture in the void, and then whispered: "Team Xing, Xiaoxiao, it's not far from solving this case, this is very likely to be left by the murderer, and it is the murderer we can find!" ”

I looked at Leng Tong's comparison, and my heart suddenly woke up, this big beauty is really powerful, and she deserves her name!

Team Xing obviously didn't react for a while, looked at Leng Tong and asked, "Xiao Leng, why do you say that?" ”

Leng Tong stopped talking, staring at me with big eyes.

I really don't understand, this beautiful woman knows it, but she always doesn't say it, as if she deliberately wants to give me credit.

Team Xing didn't care about that, and seeing that Leng Tong didn't speak, he immediately cast an inquiring glance at me.

"Team Xing, look at the location of this trace, between the two doors of the refrigerator, a little down." I can only tell Team Xing: "According to our previous inference, according to the murderer's size is about one meter six, then, if he is holding the refrigerator and opening the refrigerator door, it should be in this position, Uncle Li is not short!" ”

"Yes, yes!" Captain Xing was sincerely happy this time, and said with a smile: "Gao Ming, Gao Ming!" It's really not far from solving this case! ”

"You can't startle the snake!" Leng Tong whispered: "Team Xing, if our inferences are all true, and these things are still found in front of us, then this case is not a crime committed by one person, I guess there must be a criminal gang behind, even if we can find one of the murderers, there is also a gang behind!" ”

We all understand Leng Tong's words, judging from all kinds of signs, it seems that there is also a case of reselling human organs, then it is not a person who can do it, one of the murderers should indeed be on campus, if we catch this murderer, then the members of other gangs are likely to flee!

When Team Xing came in the morning, he was still frowning, he was so anxious that he was going crazy, and the pressure was very great, but at this time, he was overjoyed, and nodded at the two of us, signaling the two of us to come out first.

When he walked to the door, Captain Xing told Li Li to extract the fingerprint on the side of the refrigerator as soon as possible, and then went directly out of the door.

The two of us followed Team Xing to a secluded place, and Team Xing said with a smile: "For so many years, except for Lao Wei who can help me, I am fighting alone, but I didn't expect that not long after the two of you joined the work, you are about to help me solve a big case!" Are there any questions about this case? ”

Leng Tong no longer stiffened his face at this time, but he didn't show any smile, and he didn't say anything.

I can only analyze it again for Team Xing.

The corpse killed again, this is still nonsense, and the first scene of the crime can be determined, it is at Uncle Li's residence.

Judging from the scene, the refrigerator and liquid nitrogen in Uncle Li's room can prove that they are related to this case, otherwise Uncle Li would not have these things in a guard room at all, and other frozen utensils may have been transferred by the murderer, and the scene has been dealt with after all.

This can be concluded that Uncle Li must also be involved, and it is very easy to be exposed, and yesterday we also asked Uncle Li for the key to the back door, which made the murderer a little frightened, which made the murderer have to kill people.

Judging from the fact that Uncle Li was killed and his frozen organs were involved, it can be inferred that Professor Li Guanli was also killed because he was involved in this case.

Then everything suddenly came through, and now the only person who knows the inside story is the murderer inside, and the murderer outside is likely to be the member of the organ reselling gang.

I briefly analyzed it for Team Xing, and then said with some regret: "Actually, yesterday I also thought that Uncle Li might have some problems, he has the key is one of them, he is often here, and some insiders may also know, but I didn't expect Uncle Li to participate in helping to freeze organs and be killed!" ”

"Yes, I didn't expect that yesterday we still wanted to solve this case quietly!" Team Xing sighed and said: "Don't mention it now, what has happened, two people have died in a row, the murderer is still suspicious, this case must not be delayed, otherwise the impact will be greater, what to do next, tell me your opinion!" ”

Leng Tong stared at the big eyes again and stopped talking, and I could only say according to my thoughts: "Team Xing, we have analyzed so much before, and we have also found some characteristics of the murderer, I believe it is easy to lock the murderer, the murderer is an insider, and it is very likely that it is in this teaching building, or you go to the principal and cooperate with our investigation." ”

At this time, Leng Tong took it and said: "Yes, this method is good, let's meet these tutors directly, start from this teaching building, and investigate and understand them, it is normal." ”

Team Xing immediately nodded and said, "Okay, let's go, let's find Principal Qi to cooperate, and now we will start looking for teachers to investigate the situation one by one, and strive to lock the target as soon as possible!" ”

The three of us have made a plan, and before we have walked a few steps, a few people in front of us hurriedly walked over, and the middle one is over the age of six, with gray hair, a straight nose and a square mouth, and the momentum is extraordinary.

The Xing team also immediately greeted him, called Principal Qi, and immediately told Principal Qi about the situation of the case, and said that it was best to let Principal Qi help, and it was best to gather everyone so that we could investigate one by one in a short time.

Principal Qi is more anxious than us, we are under pressure, and the superiors attach importance to urging, but Principal Qi is facing the inability of the school to operate normally, such a large campus, tens of thousands of students, that is okay!

Principal Qi immediately nodded and agreed, let us go upstairs and sit down first, and he immediately gathered the professors and teachers in the small conference room, cooperated with the police to handle the case, and inquired about the situation one by one, and tried to solve the case as soon as possible.

The Xing team was very happy, and hurriedly called the deputy captain Gao Peng and Lao Wei to investigate and understand the situation in groups.

Leng Tong's big beauty also looked for a female teacher behind the principal at this time, asked where the small conference room was, gave me a look, turned around and went upstairs.

As soon as I heard Leng Tong ask about the location of the small conference room, I understood what this big beauty was going to do, and sure enough, she was smart, and hurriedly trotted two steps to follow, and asked with a smile: "Tongtong, should we go and wait first to see if we can find someone who matches the physical characteristics?" ”

"What do you call me? Call sister, you know? Leng Tong paused for a moment, glanced at me, and then said: "Count you smart, our speculation will not be wrong, go!" ”

I just blurted out when I was happy, Tongtong's name is very smooth, it's good, although Leng Tong glanced at me, he didn't look too angry, so he smiled and agreed, and followed Leng Tong to the door of the small conference room on the fifth floor.

Team Xing and the others also came up quickly, and when they saw the two of us standing not far from the door of the conference room here, they smiled and didn't say anything, and followed Principal Qi into an office next to them.

In just ten minutes, some teachers and professors walked to the conference room, some of them whispering something.

Leng Tong motioned for me to turn around a little bit, don't stare closely, but the corner of my eye was staring at these people.

Speaking of the faculty and staff, there are always more than thirty looks, the women are temporarily excluded, the two of us only stare at the men, the shorter ones, the fifty-year-old ones, and some of the little ones, if the professor appears in our sight, these characteristics are enough.

At first, there were a large number of people who went in, and then there were fewer people, and they came up sparsely, and we kept staring, and there was no one who met these characteristics at all, even if there were some that barely met, there were also one or two things missing, either the age gap was too big, or there was no point, or it was not fat.

The two of us looked at each other, and there were some doubts in each other's eyes, could it be that the murderer inside was not in this school building? Or is there something wrong with what we speculate?
