Nan walked to the body and looked at the purple-red particles collected in Wu Fayi's evidence bag. He seemed to realize something.
"Xiaotao, hurry up and check if there is anything like ham sausage in this room." Qin Nan stood up and looked at Ma Xiaotao and said.
Ma Xiaotao didn't ask much. She also knew what Qin Nan was thinking. Several people found a black plastic bag by the window of the house. When they opened it, they found ham sausages wrapped in black plastic.
.
At a glance, several people understood that these were the ham sausages used to poison the pets. From this, it can be seen that the key suspects in this case were those who had pets, or that their pets were poisoned to death and then sought revenge from the murderer.
If the purple-red drug in Xiang Chuang's mouth was tested, it should be an ingredient similar to the poisonous drug, because it was very similar to the pack of poisonous drug he saw at the property this afternoon.
The crime-solving team members left the scene of the crime one after another, and Xiang Chuang's body was sent back to the forensic room of the bureau by the police. Wu Haotian and Qin Nan came to the property and handed over the poisonous rat in the property to Ma Xiaotao.
And asked her to hand it over to Wu Fayi and the others to see if the ingredients in the poisonous rat poison were consistent with the poison in the victim's mouth.
"You don't want to sneak back, do you?" Ma Xiaotao said as he took the pack of Poison Rat Qiang.
"You actually think so, that's right. I just want to check the surveillance at the property to see if I can find any relevant clues. You should be fine after you return to the police station." Qin Nan said.
Ma Xiaotao looked at Qin Nan up and down, without saying anything, and left the property directly and returned to the police station.
Qin Nan and Wu Haotian sat in the monitoring room of the property. The security guard was also sitting nearby, warming himself by the stove and fell asleep. It seemed that there was someone here, which made him sleep so peacefully.
Qin Nan brought a pen and paper and sorted out the timeline for tonight.
The anchor started the live broadcast around 21:00. At 21:20, there was the noise of karaoke in the live broadcast room. At 21:26, the anchor stopped broadcasting and at the same time called the video in the group.
At 21:36, because the live broadcast room was too noisy, I downloaded the broadcast in the group, and then called the property management to complain. I met Aunt Wang at 21:43, and got on the elevator at 21:46.
According to the traveling speed of the elevator, it should have reached the victim's floor at 21:47, and the victim died of poison just when he was discovered.
Qin Nan looked at the time, it was already 11:30 in the evening, and he called Wu Fayi.
"Fayi, have you found out what kind of poison it is?" Qin Nan asked.
"We found out that it is an acute poisonous rat poison, which is called 'dead by smelling it' among the people. This thing is impossible to buy because it is so toxic that pets will basically die if they smell it.
Like in some previous videos, the pet dog passed through some places and after smelling it, its body began to twitch within a few seconds. If a person eats it by mistake, it should be fine if the stomach is washed in time.
However, the victim actually ate too much, and it was force-fed, and a lot of 'death at first smell' was found in the trachea of the lungs," Wu Fayi said.
"How long will it take for the current amounts on the victim to cause death?" Qin Nan asked.
"Five minutes." Wu Fayi said.
"Are there any signs of defensive struggle on the victim?" Qin Nan asked.
"Yes, now we have found slight strangulation marks on the neck. I judge that they were pinched with hands, but they are not obvious." Wu Fayi said.
"Okay, thank you for your hard work." Qin Nan hung up the phone after saying that, and then wrote three words on the white paper: five minutes.
He took the pen and then looked at the surveillance camera. At 21:43, he met Aunt Wang. At 21:47, he noticed that the victim's body was twitching. There was another four-minute error in between.
Qin Nan swallowed and looked at Aunt Wang inside the surveillance camera. Her eyes suddenly widened. The pen that was originally spinning in her hand also fell to the table at this time...
The next morning, Qin Nan explained the situation to Song Yi. He and Wu Haotian would not clock in at work this morning because he had a major suspect.
Qin Nan looked at the time, it was seven in the morning, because Qin Nan roughly knew the time when Aunt Wang went to work, and it was always around eight o'clock, so he probably got up at this time.
"Dong, dong, dong..." Qin Nan knocked on the door and calmed down his emotions, because he did not want Aunt Wang to be the murderer. He knew her best and there was absolutely no way she would do such a thing.
And there is no conflict of interest between Aunt Wang and Xiang Chuang.
"Who is it..." Aunt Wang opened the door and found it was Qin Nan.
"Hey, Officer Qin, what's the matter so early?" Aunt Wang asked.
"Um, Aunt Wang, I have something to do that will delay you for ten minutes. I have a question I want to ask you." Qin Nan said hesitantly.
"Come in, let's talk later. I happen to be cooking noodles. Have you had breakfast?" Aunt Wang asked.
"Um, it's not over yet. Thank you Aunt Wang." Qin Nan wanted to refuse, but he didn't know why he agreed.
He walked into Aunt Wang's house and closed the door. The house was very neatly tidied. Although it had a cement floor, it looked much more comfortable than the house he lived in now.
There are also several bags of cat food, cat litter, and two cat climbing frames in the room. It is obvious that Aunt Wang likes cats very much.
"Meow~" At this time, on a cat climbing frame in the corner, Xiao Hui was looking at Qin Nan, as well as an orange cat and a white cat. This was the first time he saw these two cats.
"Aunt Wang, did you raise this too?" Qin Nan asked.
"Yes, that's from my friend's house. There are too many stray cats in her house, so I'll help her share the burden. By the way, do you want chili oil?" Aunt Wang said while mixing the seasoning.
"Yes, thank you Aunt Wang." It didn't take long for Aunt Wang to cook the noodles. Qin Nan picked up his bowl. The aroma of the chili was still the same as before.
When he was at school, every time he passed by Aunt Wang's door during meal time, he would smell a particularly fragrant chili aroma. He really wanted to try it, but he was too embarrassed.
Qin Nan hurriedly stirred it evenly and took a sip. He felt that the taste of this homemade noodles was slightly better than the noodles cooked by Wu Haotian.
"How about it? Let's have some flavor?" Aunt Wang asked with a smile.
"Yeah, yeah, it's delicious, even better than what my cousin makes!" Qin Nan said while eating.
"By the way, Officer Qin, what do you want from me?" Aunt Wang said, stirring the noodles in her bowl.
The noodles that Qin Nan was about to put into his mouth also stopped in mid-air at this moment. He really forgot the purpose of coming here for a moment.
He looked at Aunt Wang, then put down the chopsticks in his hand, organized his words and said:
"That's it, Aunt Wang. There was a murder on the eighth floor of the second building last night..." Before Qin Nan could finish speaking, Aunt Wang's eyes widened and she said, "What murder? Oh my God."
"Well, there was a murder on 8-4, so I want to ask you if you noticed anything unusual when you left the eighth floor and got into the elevator last night?" Qin Nan asked.
"Abnormal? No abnormality was found?!" Aunt Wang said with a frown.
"Do you know the victim? His name is Xiang Chuang." Qin Nan asked.
"I don't know you. I've never heard of this name..." Aunt Wang seemed to realize something. Her eyes that were originally widened widened a bit, then she frowned, stood up and said:
"Officer Qin, are you suspecting that I killed that person named Xiang Chuang..."
"Aunt Wang, don't get excited. We are just suspicious, so I just want to ask you if you noticed anything strange, or where were you at that time?" Qin Nan also stood up and smiled awkwardly.
"I'm at my friend's house. These two cats were brought here from my friend. She can vouch for me," Aunt Wang said.
"Do you remember what time it was when you left your friend's house?" Qin Nan asked.
"It seems to be between half past nine and nine forty. I forgot the specific time." Aunt Wang looks like you are a little anxious and want to recall the specific time.
"Aunt Wang, don't worry, we just wonder where your friend is on the 8th floor. Let's go ask her about her situation." Qin Nan asked.
"I'll come with you. I just have a rest today." Aunt Wang said as she took off her apron, as if she wanted to go out immediately.
"Well, Aunt Wang, there's no need to be in such a hurry. It's not too late to leave after I finish eating this noodle..."
