"Tian Nan! Come out!"
Wen Sibao pulled Xu Tiannan out of the command room without any explanation. After a long explanation, the other party understood what happened just now and asked in surprise: "Fourth Master, what do you mean... Meng Qinghan?
You haven’t come to the bureau in two days?”
Wen Sibao nodded, "Just like you, I can't contact anyone."
"I go!"
Xu Tiannan let out a long sigh and said, "She is her, and I am me. No one will think that I have been with her these two days, right?"
Wen Sibao smiled bitterly and said, "What do you think? Didn't you see the way Ah Shui looked at you just now? He was almost angry."
Xu Tiannan hesitated and said: "According to what you said... Shui Gen's current mood is not right?"
Wen Sibao curled his lips and said: "It's not just wrong! Seeing that the man he likes is doing the same thing and saying the same thing as his ex-girlfriend, it's like something that can only be done by people with connected minds. You
Do you think this kind of thing will be easy for Ah Shui? Let me tell you! You should think about how to explain it to her first!"
Xu Tiannan: "I...what should I explain?"
Wen Sibao: "Of course I want Ah Shui to believe that you and Meng Qinghan are not doing something... to rekindle an old relationship."
Xu Tiannan said unconvinced: "It's a shame to revive an old relationship! I was the victim back then, and it was Meng Qinghan who dumped me. How do you want me to explain this kind of thing?"
"Definitely!"
Wen Sibao waved his hand and said, "You can keep talking to Ah Shui about this by yourself. I don't want to get involved. Now back to the subject, what Meng Qinghan just said at the case discussion meeting, Deputy Director Yang has already
A search and arrest operation has been launched in the main house. What you have to do now is to put other things aside for a while. After you go in, share the clues you have investigated in the past two days with everyone. Do you understand?
"
Xu Tiannan took a deep breath, then bravely walked into the command room.
Xu Tiannan obediently followed what Wen Sibao taught him this time. When he walked into the command room, he first smiled stiffly at Murong Shui, but was frightened by the angry look in his eyes and immediately moved away.
caught sight.
Of course, Deputy Director Yang also felt that the atmosphere between these people was a bit strange, but after all, the case was imminent, so he had no choice but to ask Xu Tiannan: "Mr. Xu, you just said that you also discovered some doubts in this case, what do you think about it?"
?"
Xu Tiannan nodded, "Yes, in addition to what Captain Meng just said about prolactin at the veterinary station, call recordings and the investigation of unemployed people, I think there is another clue that can be investigated."
"Speaking."
Xu Tiannan cleared his throat and walked onto the podium, but did not dare to look directly at Murong Shui in the audience. Then he projected an electronic version of the inspection report on the screen and explained.
——"The direction of the investigation I want to say is actually related to this mad dog. In fact, just after yesterday's shooting incident, I went to the shelter and saw the mad dog."
——"According to another police officer at the scene, everything that happened at that time was too coincidental. The mad dog happened to get into the car, and the scene of the car accident attracted the Wu brothers and Zhao Luobo."
——"So I think we only need to rely on one characteristic of this mad dog as a breakthrough in this case."
——"Then we need to determine whether this mad dog was captured from the wild by the murderer, or has been kept by the murderer?"
Meng Qinghan responded.
——"I have already tried this question, but I didn't get an answer."
——"Just this morning, I tied the dog with a long rope and brought it back to the scene of the crime."
——“I originally wanted to throw it to the crime scene to see if I could find the way home through dog scent analysis, but I found that the dog was running around aimlessly and almost got bitten in the process.
Passersby."
Xu Tiannan explained.
——"I can probably guess the situation you mentioned. If I were really the murderer, I probably wouldn't have made such a big flaw."
——"After all, the murderer only had to drive the dog to the scene of the crime, and then spray disinfectant, irritating scented items such as Fengyoujing or chili oil on the way there, which could interfere with the dog's sense of smell and make it more dangerous.
The dog can't find its way home."
——"But there is a most direct way to determine whether this mad dog is wandering in the wild or whether it was specially raised by someone."
After finishing speaking, Xu Tiannan clicked on the inspection report on the big screen and continued to explain.
——"Just after the incident occurred yesterday morning, I took some fecal samples of this mad dog and asked my colleagues in the university laboratory for test reports."
——"Before that, I want to tell you one thing, that is the stray dogs we usually see. They often eat leftovers, carrion or garbage discarded by others in the wild."
——“Therefore, the feces of stray dogs will definitely contain different components of putrescine, cadaverine, Staphylococcus aureus or botulinum toxin.”
——"But according to the feces test report of the mad dog at the time of the incident, the feces of the mad dog did not contain the above ingredients, but instead contained a large amount of meat, cereals and various undigested vitamin additives.
.”
——"So I can tell you with certainty that although this mad dog looks dirty and refuses to get close to people, it has been kept in a cage for a long time."
Deputy Director Yang attached great importance to Xu Tiannan's inspection report, so he immediately asked: "In this case, can we determine the type of dog food based on the ingredients in this feces sample? So as to find out where the murderer bought it.
Dog food?”
Xu Tiannan: "It's very difficult. The meat, grains, vitamins and other ingredients we tested this time. Generally speaking, all dog food contains the above ingredients, but some are chicken ingredients and some are beef ingredients, so this
The road is impassable."
Xu Tiannan said, and suddenly changed the topic: "But my colleagues in the laboratory found conclusive evidence in the fecal samples of this mad dog."
