I shook my head, habitually glanced at the person opposite, and when I boarded, I froze in place. Because on the opposite wall, there is a point of light, which is the point of light that reflects the light of the metal substance! Looking down, in the flower pot, a very small but dazzling light was also reflected!

I hurriedly took a photo of the archive, put on gloves, and gently peeled off the leaves of the flowers, a substance resembling a porcelain shard, revealing a horn in the soil.

And that light is reflected from this thing.

I hurriedly informed Xu Liang, and in a few moments, they came.

In half an hour, more than a dozen porcelain fragments were cleaned out in this flower pot, and after comparison, these fragments all belonged to the same piece of porcelain.

At 3 p.m., they replied: from the thirteen fragments, the residue of insulin was extracted.

No wonder, the cause of Wang Jiumei's death has not been found, it turned out to be insulin. Insulin is a drug that has a significant effect on diabetics. It enters the human body and lowers blood sugar. However, once the intake exceeds the tolerance range of the human body, it will cause life-threatening!

Even better: before a person dies, the body quickly releases a large amount of blood sugar, which brings the blood sugar level back to normal.

"We've taken two different fingerprints from this fragment!"

Hearing Xu Liang's words, I was overjoyed that there had been a breakthrough in the case.

"How long does it take?"

Xu Liang paused and said, "The result will be available at about 8 o'clock." ”

I nodded, and now it is basically certain that these two fingerprints are inseparable from Wang Jiumei's death, and it is very likely that they were left by the murderer.

After anxious waiting, the results of the comparison are finally out.

One is from Chen Cheng, and the other is from Wang Cailing!

I was not surprised by the first fingerprint, but the second one was Wang Cailing's, which surprised me very much!

Wang Cailing was admitted to the hospital at 10:38 a.m. on the 12th, and Wang Jiumei was found dead in the rental house at 4:05 a.m. on the 13th, and the time of death was 22:00 on the evening of the 12th.

And just now, the composition of atropine has been detected in Wang Cailing's body, and it is 3 times that of a normal person! The situation in front of me made me have no time to think, even if I applied for the summons document against Chen Cheng, and at the same time notified the forensic doctor to speed up the treatment of Wang Cailing and speed up the autopsy of Wang Jiumei.

When Chen Fang learned the news, he and I took Xiao Liu and others to summon Chen Cheng with documents.

But when we arrived at the tube building, we learned that Chen Cheng had disappeared like the world!

"Now Chen Cheng is the number one suspect." I said to Chen Fang.

Chen Fang agreed with me, so we began to investigate, asking Chen Cheng's family and neighbors when he was last seen. Because what we need to determine at the moment is: Chen Cheng ran away? Or was it also killed?

As for whether he might go out and buy something or something? That's almost zero. Because we have already understood earlier, Chen Cheng is an otaku who needs to rely on his parents for help.

It's a pity that the result disappointed us, because no one knew when Chen Cheng left, and most people had no impression of him as a person.

In desperation, we had no choice but to go back to the police station first. Because the case was at an impasse, I sat down at the conference table, arched my hands, and pressed my fist against my eyebrows.

The details of the case, one by one, passed through my mind like a slideshow. From the time I didn't come here, before I got in touch with this case, to when I came, I encountered all kinds of strange things.

Is it really just a coincidence?

Just as I was thinking about it, a voice suddenly came to my ear: "What should we do now?" ”

When I heard this voice, I immediately raised my eyes, but I was actually startled in my heart. After looking at it, I realized that the person who appeared next to me was Chen Fang.

"It's you, who else should I be, and I was startled." I whispered.

He immediately sat down next to me, looked back at me, and asked, "Are you okay?" Why do you look a little dazed, you shouldn't have had a good rest these days, right? ”

"Well, this case is not that simple."

Chen Fang probably saw that I looked stunned, so he got up again and said to me, "I'll go and make you a cup of coffee first." ”

Although I said no, he still went, and said while making coffee: "Actually, you don't have to pay too much attention to this case, after all, so many of us have spent so long and no clues have been found, in fact, you have done a good job." ”

Just as he brought me the coffee, I just said, "You've changed!" ”

"Has it changed?" He smiled, put the coffee on the table in front of me, sat down next to me and said, "I don't think I've changed, if I really have changed, then it can only be said that the wise man went with the flow." ”

I shrugged, took a sip of the coffee he had made for me, and asked, "You don't seem to have said your personal opinion on this case?" ”

"Weird! It's a lot of cats! That's his assessment.

I looked at him with interest, and carefully recalled the facts of the case, and sorted out all the people involved in the case. In an instant, many names came to my mind, and many faces also appeared.

Then, I asked, "Actually, what do you think are the chances of Chen Cheng committing a crime?" ”

Chen Fang thought for a moment and said: "80%, now he may be worried about the East Window incident, so he will abscond in fear of crime." "For Chen Fang's reasoning, I feel that it is very reasonable and reasonable.

And after Chen Fang thought about it for a moment, he said: "There is also Wang Cailing, which is actually very suspicious. Lao Lu, think about it, why did she go to a mental hospital in the morning, and Wang Jiumei died that night. If that's true, it's too much of a coincidence, isn't it? ”

I gently placed my hands on the table, stacking them on top of each other, making a very serious appearance. After careful consideration, I shook my head and said, "It's hard to say, I don't know if you've heard that there is some kind of connection between relatives?" ”

As soon as the words fell, I saw Xiao Liu walk in from outside. As soon as he came in, he raised his eyes to look at me and shouted, "Advisor Lu." ”

I immediately asked, "Any news?" ”

"Nope!" He walked over slowly, "Actually, that's what I'm talking about, and now I don't have any clues." So aren't you leaving? ”

I turned my head to look at Chen Fang, wanting to see what he meant. I saw him look back at me, shrug his shoulders, and smile faintly.

It's just that I already understood what he meant, so I turned my head and said to Xiao Liu: "You go out first!" We still have something to discuss. ”

Xiao Liu answered, and then left. The two of us watched him leave before continuing the conversation.
