I hung up the phone and said to Ling Fei, "The poison has come out, it's rat music, a kind of rat poison with blood toxicity." Pen %Fun %Pavilion www.biquge.info"

Ling Fei reacted quickly, as soon as she heard this amazing news, she immediately reacted, she said, "Teacher Su, then should we hurry up and extract these samples from the scene?" ”

I said, "Well, we need to hurry." ”

The first thing that came to my mind was of course the milk carton in the attic bedroom, this box is now an empty box, since in Liqiang's bedroom, it was either Liqiang who drank it, or Xiuxiu drank it, so I don't care about it so much for now, let's test it.

And the food residue in the kitchen trash can, of course, also needs to be brought back and inspected immediately.

I said goodbye to Xiao Wang, hurriedly left the small supermarket, and rushed back to Yejiawu, the forensic research institute is like my base camp, providing a steady stream of technical support, strong support is my continuous breakthrough strength.

When I returned to the unit and handed over the samples to Wu Haoyu in the laboratory, I returned to the office and immediately reported the comprehensive situation to Liu Da.

Liu Da said: "I think this is basically a poisoning case, you should pay special attention to the investigation site, and be sure to find the source of the poison." ”

I said, "Okay, if necessary, we'll ask someone from the lab to investigate the site, and we'll find the source of the poison." ”

Liu Da said: "I will send an elite to investigate here, and I will definitely find out something." ”

Hanging up Liu Da's phone, I was thinking in my heart, if it is determined that it is a poisoning case, then the most likely way to poison now is food, Liqiang's main meal now does not seem to be very similar, because Liqiang is eating with Xiuxiu, I suddenly thought about it again, why did Liqiang hear the doctor say that he suspected poisoning and did not call the police immediately, and waited until the doctor persuaded him to call the police? In this way, did Xiuxiu eat with Liqiang, and how long did Xiuxiu take until she finished eating? It seems that all samples must be treated equally, and until Wu Haoyu's results come out, everything is possible.

I was going to go to the hospital to ask some more questions, but now it seems that it is completely unnecessary, since no one can believe it, it is in vain to ask, so I just waited for Liu Da's investigation and Wu Haoyu's test results, which can be regarded as waiting for work.

I leaned back in my chair, looked through Forensic Toxicology, found the chapter on Rat Music, verified the mechanism of poisoning and the manifestations of poisoning, and everything was on track.

In the evening, I saw that Wu Haoyu's results had not come out, so I went to the laboratory to see what Wu Haoyu was doing, I rang the doorbell, Wu Haoyu came to open the door, he said, "What? I can't wait so much, I'm coming to the door. ”

I said, "How can you not be in a hurry?" This case is on you. ”

Wu Haoyu was working on the last procedure, and I was sitting in his laboratory, watching him busily operate on the machine, and suddenly I found myself sitting and doing nothing, and watching others work turned out to be a very pleasant thing.

Wu Haoyu said: "Su San, all the samples in front of me have been sacrificed, and they are all negative results, don't say it so seriously, my hands are shaking." ”

I said, "Don't, don't shake, you shake, wait until the case is gone." ”

Wu Haoyu injected the extract into the instrument, clapped his hands and said, "Just look at this needle!" ”

I looked at the computer monitor next to the instrument, on which the data stream transmitted from the instrument moved slowly, and Wu Haoyu kept recording it in his inspection notebook.

Wu Haoyu's spacious laboratory is full of all kinds of instruments, many of which I can't even name, most of them are chemical analysis instruments, usually I only look at the test results, and I have never observed the laboratory so closely as tonight.

Not long after, Wu Haoyu said, "There is." ”

I immediately slid my wheelchair over, and by this time Wu Haoyu had already laid out a table on a piece of paper, on which I recorded in detail the various samples I sent for testing.

Wu Haoyu said: "I have listed this table very clearly, you can see it yourself." ”

I took the form and was amazed, only the last specimen detected the rat, which was the milk carton on the table in the attic bedroom, which means that the kitchen trash can residue I sent for inspection and the various food items on the shelves were not found to be poisonous.

I said, "Wu Haoyu, the case is settled, the source of the poison has been clarified, it is this milk carton." ”

I took the report and called Liu Da, who was very happy when he heard it, and he said: "That's right, you are now in the police station, and we have also investigated some suspicious things, so we just need to discuss them together." ”

The police station was already full of people, and when I went in, Liu Dazheng said: "At present, it seems that there are several clues, the most important one is Liqiang himself, although the possibility of poisoning his own child is relatively small, but some of Liqiang's practices are still questionable, according to him, he said that he heard the doctor say that there was poisoning and called the police, but the doctor said that he called the police under his repeated persuasion, which is always not very reassuring." ”

I found an empty seat and sat down and said: "There is a table in the bedroom in the attic of the scene, and the same rat poison was detected in an empty milk carton on it, and now it seems that the way of poisoning can be determined, the murderer put the rat music into the milk carton, and Xiuxiu drank the milk without knowing it." ”

A police officer asked, "Is the source of the milk determined?" ”

I said, "Because Liqiang's house itself is a small supermarket, he has the same kind of milk on the shelves, and even the production date is the same." ”

The police said: "The production date is the same? Is it possible to assume that this poisonous milk is taken from this shelf? ”

I said, "It's more likely, at least other supermarkets might sell milk with the same production date, I know what you mean, are you skeptical that you're most likely to get this carton of milk from the shelf?" But I want to say that even if only Liqiang's supermarket sells this batch of milk, other people can go to Liqiang's house to buy milk first, and then take it back to Xiuxiu to drink after poisoning? ”

Liu Da said: "We will go to the manufacturer's sales channels for further verification of the production date of this milk, but at least one thing can be said that there is the same batch of milk in the small supermarket of Liqiang, so Liqiang cannot escape our sight." ”

Another police officer said: "I learned about a situation here, which I went to ask with Xiao Wang at the police station, and a neighbor of Liqiang reported that Liqiang's wife died suddenly three years ago, and he felt something abnormal, and Liqiang told others that his wife died of a cerebral hemorrhage." ”

I asked, "Liqiang's wife died of a cerebral hemorrhage?" Do you have any medical records from the hospital? ”

The police said: "Later, we went to Liqiang to verify the situation, and Liqiang said that his wife usually had high blood pressure, and the death of cerebral hemorrhage was judged by himself, and there was no medical record to prove it." ”

Death from cerebral hemorrhage? If it is really a cerebral hemorrhage death, then there should be a coma process, can it be considered the other way around, at that time, Liqiang's wife suddenly fell into a coma, so Liqiang judged that it was a cerebral hemorrhage death?

Coma? I immediately had the appearance of Xiuxiu in a coma in the children's hospital in my mind, is there any connection between Liqiang's wife's coma and Xiuxiu's coma?

I casually asked, "After Liqiang's wife died, was the body cremated at that time?" ”

A police officer from a police station said: "Liqiang's wife's body was not cremated at that time, but was transported back to her hometown. ”

After I heard the news, I was very surprised, as long as there is no cremation, if the case needs to be the next step, you can also consider an open coffin autopsy on Liqiang's wife, I said: "So, Liqiang's wife's body is buried, and after three years, the bones should still be there." ”

Liu Da said, "Su San, what do you mean?" ”

I said, "I'm just thinking about it now, just ask, and I'll see when the time comes." ”
