Gu Feng walked forward, looked down, and found that it was an empty two-milliliter injection bottle, and there was still a little liquid left in it.

He waved to the village chief of Baogen, and the village chief of Baogen immediately stepped forward, and when he saw what Gu Feng was pointing at, he was about to reach out and pick it up, but Gu Feng hurriedly stopped him, "Village chief, look at this is the mouse medicine that you accidentally killed your dog last time!" ”

The village chief of Baogen stepped forward, looked carefully and looked at it again, and finally nodded with great certainty. "Yes, that's it, the village issued a certificate, and then went to the county to buy it."

"Huh? Isn't this rodenticide available everywhere and has to be bought? Gu Feng asked.

"Of course not, the drugs used to kill rats are often highly toxic, and several years ago the government has begun to repeatedly decree that it is not allowed to sell rodenticide at will, if there is a rat infestation, you can consult the Patriotic Health Association, and then go to the designated drug sales point to buy rodenticide drugs!" "Even if I had the certificate, I only bought three boxes, and I had already sold them all last time. ”

"Nothing left?" Gu Feng asked.

"Nope!" The village chief shook his head.

Gu Feng nodded, then returned to the consultation room, took a camera, and carefully picked up the empty bottle and put it into a plastic bag. As a special police officer, if he didn't even know how to collect some evidence, he would have participated in hellish training for so long in vain.

After taking the bottle back to the living room, after falling into a short silence, Gu Feng's eyes swept over everyone again, and then stopped on Yan Xinyue and said, "Teacher, let's go to the countryside this time, is there such a drug as rat killer among the medicines we have prepared?" ”

Yan Xinyue thought for a while, nodded and said, "Yes!" Since I came to the countryside this time, I applied for rat poison because I was thinking that there would be rats. ”

"After you came, did you prescribe this medicine to the villagers?" Gu Feng asked again.

Yan Xinyue shook her head, "If it weren't for this incident, I would have almost forgotten about this highly poisonous rat poison." I can't even remember when there were rats upstairs! ”

"Then who can usually come into contact with this medicine?" Gu Feng asked again.

"You can!" Yan Xinyue said stunned.

"Teacher, will I still take the medicine and put it into the meat I eat? I'm in the water! Gu Feng couldn't cry or laugh, and then said, "I'm asking you who else besides me can come into contact with this drug." ”

Your brain is always in water, otherwise you would be entangled with so many women? Yan Xinyue thought so in her heart, and then replied: "In addition to you, there are also me, Zhang Chaoqiang, Ning Qingzhong, and Shui Lanlan can all come into contact with this medicine. ”

"Oh, then you can see if this is our medicine?" Gu Feng handed her the bottle in a plastic bag.

Yan Xinyue looked at it for a while, shook her head and said, "How can you see it like this, you have to compare the model batch number to be clear!" ”

"Then let's go check it out!" Gu Feng Road.

"But didn't you let me out of here?" Yan Xinyue said aggrievedly.

Why are you so brainless, Gu Feng really wanted to spray her, but now he was not in such a mood, and opened his mouth and said, "Now I approve you can leave!" ”

Yan Xinyue got up at this time, ran to the room dedicated to storing medicines, and then brought a small cardboard box.

"This is the box of rat poison, which has not been opened since I went to the countryside...... Hey, how did you open it! And there's one box missing. Yan Xinyue was talking, but found that the carton had been opened, and after opening, there was obviously a small box missing.

"Let's take a look at the model first!" Gu Feng urged.

Yan Xinyue hurriedly compared, and nodded after a while, "Yes, this is the model." The batch number and production date are matched! ”

Gu Feng groaned for a while, and then said: "In this case, it would not be surprising that there is one less box, because this missing box must have been taken by the murderer, and now I already know who is going to drug me!" ”

As soon as these words came out, everyone couldn't help but be surprised, just interrogated a few words, and then found an empty bottle, compared it a few times, and already knew who was the murderer?

This is really too godly! Sherlock Holmes reborn?

"I already said just now, the meat was poisoned after it came out of the pot, if it was a golden lock, she shouldn't have poisoned herself and then personally took the meat to me to eat!" Gu Feng Road.

"It's like, I'm so stupid!" The golden lock is very much the way of the two hundred soldiers.

Gu Feng felt a little funny, but he couldn't help it, and continued very seriously: "It's not the key whether Jin Suo is stupid or not, the key is that she can't come into contact with this drug. In addition, if she really wanted to poison me, she would not pour the meat to the dog, and the reason why she poured the meat to the dog was purely accidental. Why did it say it was an accident, she should have explained it in detail just now, we had a fight, and she poured the meat to the ground in a negative anger. In other words, she didn't know that the meat was poisoned beforehand! ”

"I should give it to you, I should give it to you!" Jin Suo's resentment was great, so he naturally opened his mouth and came.

Gu Feng didn't answer her stubble, but continued: "If this point can be established, then you can be sure of another point, that is, this meat, it was put in by someone in the process of Jin Suo packing up the dishes and chopsticks and coming out to serve food for everyone, and from this point continue to deduce, then there are only two people who are the most suspicious, one, it is Chu Xinran!" ”

"Me?" Chu Xinran was originally just crying silently, but after hearing this, he immediately began to cry.

Gu Feng didn't care about her, but continued: "The other, that is Zhang Chaoqiang!" Because of this gap, the two of them were the only ones who had ever entered the kitchen until the golden lock went back to the kitchen and brought the meat upstairs. And this empty bottle! Gu Feng raised the bottle in the plastic bag in his hand, "It should be that after the murderer drugged in the kitchen, he prevented others from searching him out, and when he came out, he threw it on the patio while people were not paying attention!" But his luck is not good, and my eyes are so poisonous that I can see them all like this! This is in response to the old saying, Skynet is magnificent, negligent but not leaky! ”

In the end, Gu Feng's gaze became extremely gloomy, and he slowly glanced at everyone again, and finally fell on one person, and said word by word: "Classmate Zhang Chaoqiang, do you have to wait until the police come, take fingerprints from this bottle, and then compare them with yours to confirm that they are correct, are you willing to admit that you did this?" ”

As soon as these words came out, everyone's eyes were focused on Zhang Chaoqiang, some were surprised, some were puzzled, but more incomprehensible.

Zhang Chaoqiang's face turned white, and his whole body trembled slightly, but he still sneered: "Why are you sure of me?" ”

"Because of the two major suspects, only you can access this drug!" Gu Feng Road.

Zhang Chaoqiang's mouth opened, and he was about to refute, but Gu Feng had already continued: "Because when I was looking downstairs just now, when everyone suddenly saw me, the eyes of all of you were nothing more than several, one was dazed, the second was accidental, and the third was shocked. Although the accident and the consternation are almost the same, but there is an essential difference, the astonishment is including shock and fear, when you saw me, it was obviously a look of disbelief in the astonishment, and to my eyes, you are also obviously wandering and flickering, Mr. Zhang, we are both clinical medical students, you should have studied psychology, this point, from a psychological point of view, can it be explained as being a thief! ”

Zhang Chaoqiang was speechless, and his expression became complicated and strange.

"Taking a step back, in terms of the motive for committing the crime, you are also the most suspicious! Why do you say this, because I heard Ning Qingzhong say that in your clinical medicine class, you are an outstanding top student, sought after by everyone, and you have been covered by the halo of the protagonist, but after coming here, you were unfortunately misdiagnosed several times, but I robbed you of the edge, making you an insignificant supporting role. You hate me in your heart, I can understand it, but you hate me to the point of killing me, but it makes me too incomprehensible, classmate Zhang, is your thinking too narrow and too vicious......

"What do you know, what do you know, you don't know anything!" Zhang Chaoqiang suddenly jumped up and pointed at Gu Fengdao.

"Am I wrong? You're a shameless villain. Gu Feng knew that there was really not much he could understand, and this matter was becoming more and more complicated, because a person grabbed his own edge, which poisoned and harmed, which was too far-fetched! There must be a deeper story hidden in this story, so he deliberately stimulated Zhang Chaoqiang.

"Haha!" Zhang Qiangchao suddenly looked hideous, and laughed like crazy, "I'm a villain, but I'm also better than you, a hypocrite, do you think I'll tell you everything?" Don't you think! ”

"In that case, there's no way, you can talk to the police!" Gu Feng said and pointed out the door.

Everyone looked up and found that several off-road police cars had been bouncing on the muddy road not far away.

After a while, the police car stopped in front of Jin Suo's house, and the police officers in police uniforms got out of the car and rushed in.

Gu Feng of the parties, as well as the Jin Suo family, Yan Xinyue and others were all taken away, but when the treatment was slightly different, Zhang Chaoqiang's classmate had an extra pair of handcuffs on his wrists and rode alone in a police car that was made of steel......
