Chapter 45 Fingerprints Can Explain the Problem
After dinner, Ouyang Shuangjie and the others did not go back to the guest house, but went to the bureau and returned to their temporary office.

"You drank so much wine, can you still do it?" Xing Na asked worriedly when she saw his face flushed.

Ouyang Shuangjie smiled: "It's okay, I can do it with just this little wine."

Ouyang Shuangjie didn't brag, don't look at his gentle manner, his drinking capacity is not ordinary, and an ordinary little catty can't beat him.It's just that he usually doesn't like drinking it. It's his principle not to drink it if he can't drink it. It's not good to drink too much of this stuff, it hurts the brain.

As for smoking, he can't quit. Although it hurts his body, it helps his thinking, as long as he controls the amount properly.

Ouyang Shuangjie asked Mei Xuefang and Xing Na to go back to rest first, and then he went through the case files carefully. The two women were embarrassed to leave him alone. They said that it was still early and it would be boring to go back, so they stayed and watched with him. Dossier.

Ouyang Shuangjie watched very carefully, he always felt that there must be something he had overlooked.

"Ouyang, look at this!" Mei Xuefang handed over a document: "I drew the money part with a pencil."

Ouyang Shuangjie took it over and looked at it. This is a field survey record from that year. The piece of paper containing rat poison was placed next to the rice vat next to the stove, and it was verified by the technical department that it was indeed covered with rat poison. paper from which the tetramine ingredient was found.

Ouyang Shuangjie frowned: "Well, I remember that Tian Ruchao also mentioned this issue. He also said that there were two small footprints of Tian Ruxi's children left on the stool."

Mei Xuefang nodded: "Yes, this matter is also mentioned above, but you can read this paragraph again." Ouyang Shuangjie saw that the small half pot of white rice left by Tian Ruxi's family was mentioned later, white rice It does contain tetramine.

Ouyang Shuangjie narrowed his eyes and looked at Mei Xuefang, and finally his eyes lit up: "Thank you, thank you Sister Mei, I have been thinking that there must be something I overlooked, and now I finally understand." Xing Na nodded Mishui: "What charades are you playing, let me see!"

Mei Xuefang showed it to her for a long time and she still didn't see why. Ouyang Shuangjie smiled and said, "White rice, the problem lies in the white rice!" Xing Na froze for a moment: "White rice? What's wrong with white rice?" ah?"

Ouyang Shuangjie gave her a white look: "You carefully recall what Tian Ruchen said, how he made his fake medicine, adding incense ash and magenta, that's the way street vendors make their own rat poison. The rat poison distributed was not mixed with these things, Tian Ruchen said that the reason why he mixed these things was because the village chief asked him to buy some from the peddler, so he naturally wanted to make this thing exactly like the peddler’s.”

Xing Na understood now: "That is to say, the rat poison mixed into Tian Ruxi's family food should be left over from previous years!" Ouyang Shuangjie nodded: "That's right."

Ouyang Shuangjie took the case file and continued to look down, and then said: "It said that the police found red rice in some places in Tian's house at that time, that is, rice mixed with magenta. It should be the fake medicine that Tian Ruchen got back. Think about it, is it possible that after Tian Ruxi's wife took the fake medicine back, she sprinkled it. Tian Ruchen also said that the reason why he was in a hurry to buy rat poison was because the rats It's rampant."

Xing Na said: "But this doesn't explain the problem!"

Ouyang Shuangjie said lightly: "It can explain the problem, here!"

He picked up a physical evidence appraisal report: "This report shows that there are two people's fingerprints on that poisonous wrapping paper, one belongs to Tian Ruxi's wife, and the other belongs to their child. Take a closer look, it's How to express it, there is a clear thumbprint of Tian Ruxi's wife on the side of the wrapping paper with poisonous powder, and her other four finger prints were found on the back, so she once took that piece of paper."

Ouyang Shuangjie made a gesture: "There are creases on the paper wrapping the rat poison, indicating that the rat poison should be wrapped, but her fingerprints tell us that she did not fold the wrapping paper."

Xing Na smiled bitterly: "What exactly do you want to explain?"

Ouyang Shuangjie said: "The paper patterns left by their children are very messy. From this report, we can infer that the person who opened the wrapping paper should be that child. So can we make a hypothesis?" That is, after Tian Ruxi's wife took the fake rat poison back, she immediately took it around and scattered it everywhere, trying to exterminate the rats, but it happened that the child did not know where to find the rats that had been distributed before but were not used. The medicine, after opening it, saw rice inside, the child was very curious, so he took the thing to the rice vat to play with, the child, how did he know that it was poison, which could kill people, so he took the medicine Mix it with the rice in the rice vat to play, the rice vat is not big, and there is not much rice in the vat, so let him mix it evenly at once."

The rice vat is not big, and Mi Buduo is written in the case file. Xing Na asked: "Then how to explain the fingerprints left by Tian Ruxi's wife?" Ouyang Shuangjie said: "Tian Ruxi's wife doesn't know that her child Maybe she didn't even remember that there was this thing at home, otherwise she would have used it long ago, so it was probably when she came back to the kitchen after spraying rat poison and saw the child playing with rice Vat, life was not rich at that time, and food was very precious. At that time, it should have happened that the child had mixed rice into the paper, and she took it and poured the rice back into the rice vat. The paper was thrown beside the rice vat!"

Mei Xuefang agreed very much, she said that this assertion is logical, and the fingerprints can explain the problem very well.Xing Na said: "But just based on the fingerprints to infer that they will be convinced? Besides, it's not right that only the fingerprints of their mother and father are on the rat poison. Don't the people who distribute the medicine have to leave fingerprints too?"

Ouyang Shuangjie smiled: "The person who dispensed the medicine should have left fingerprints, but they were filtered out by the police, because the fingerprints were old fingerprints, and the time gap between them and the new fingerprints was too large, so I inferred that the medicine was from previous years." Yes. As for what you said, just fingerprints can’t explain the problem, but the test results of the rice left in the vat and the half pot of rice can. It can only be done by children, if someone intentionally poisons it, the rat poison will look the same as ordinary white rice later on, you just need to stir it gently on a flat surface, there is no need to make it so even."

Xing Na finally showed a smile on her face: "I didn't expect that such a difficult matter would be solved by us all at once. I really want to call Team Peng and the others right now. They will be shocked if they find out. I really don’t know what the people who handled the case did, they didn’t even notice such an obvious problem.”
