As Lu Yingwei and He Xiaohui drove back to the police station, He Xiaohui, who was sitting in the passenger seat, looked out the window and said nothing. Seeing her serious look, Lu Yingwei asked jokingly:
"What's wrong, beauty? Who has offended you?"
"There's no one else, what do you think?"
"Hey, did I really offend the beauty? I'm a bit flattered!"
"Okay, Brother Lu, don't be joking. I always feel that Yang Hui is a bit fishy. How could he be missing?"
"Well, I also feel that something is wrong."
"How about we go to Yang Hui's house and have a look?"
"Well, this is a good idea. Let's go see if we can find any clues in his home."
Yang Hui's home is a house with two bedrooms and one living room. The living room is small and the lighting is not good. Wu Qingxiang turned on the lights in the living room to make people feel more comfortable.
"Let's take a look at Yang Hui's belongings and see if we can find any clues about his disappearance." He Xiaohui said to Wu Qingxiang, who looked suspicious.
"Oh, please see, our home environment is relatively poor, please don't be offended." Wu Qingxiang said politely.
Wu Qingxiang took a look at the two bedrooms and saw a large bed in both bedrooms, so she asked:
"Which room does Yang Hui live in?"
"It's this room. My son sometimes sleeps with me and sometimes with him, so we have two big beds."
"Did you clean up this room after Yang Hui left?" He Xiaohui walked into the room and asked.
"No, there's nothing to clean up in his room."
He Xiaohui saw that except for a bed, a table, a chair and a wardrobe, there was almost no other debris in the room. The quilt on the bed was folded very neatly, and the pillows were also placed neatly. On the table were
Several electrical books are also neatly stacked.
He Xiaohui opened the closet and saw that the clothes in the closet were all hung on hooks, and there were not many extra hooks.
"Didn't he take away his clothes when he left?" He Xiaohui asked.
"No, it's just like this in the closet."
He Xiaohui opened the drawers on the table and checked them one by one. The cloth bags in the drawers caught He Xiaohui's attention. She picked them up and asked Wu Qingxiang:
"What's in this bag?"
Wu Qingxiang took it and looked at it carefully for a long time, shook her head and said:
"I don't know. I've never seen this bag before. Maybe Yang Hui brought it back recently."
He Xiaohui opened the bag, but there was nothing inside. Just when He Xiaohui was about to put the bag back, He Xiaohui suddenly smelled a smell. She felt that the smell was very familiar, but she couldn't remember what it was. He put the bag
Passed it to Lu Yingwei and said:
"Do you smell what this smells like?"
Lu Yingwei took the bag, put it under his nose, smelled it and said:
"It has no taste."
He Xiaohui glared at him and said to Wu Qingxiang:
"Can we take this bag back for identification?"
"Okay, no problem, you can take it."
After looking around the room, except for the bag with a special smell, there was nothing else that caught He Xiaohui's attention. When she turned around to go out, she saw that the bed sheet was tightly covering the bottom of the bed, so she bent down and lifted the bed sheet.
, saw several pairs of shoes placed under the bed. He put down the sheets and asked casually:
"What size shoes does Yang Hui usually wear?"
"Size 41."
"Oh, size 41."
He Xiaohui bent down again and took out a pair of shoes from under the bed and asked:
"Can we borrow a pair of shoes to check them out?"
"Okay, you can take it."
On the way back to the police station from Yang Hui's house, Lu Yingwei asked He Xiaohui:
"Why are you taking a pair of shoes back?"
"Didn't you hear that it's size 41? Aren't the shoes we picked up on the river beach also size 41?"
"What's wrong with code 41? I'm still code 41. Do you want me to test it for you?"
"Okay, take it off and test it together."
"Why do you doubt Yang Hui?"
"I have no reason to doubt Yang Hui. I just think the size 41 shoes are too coincidental. I just want to test my intuition."
After returning to the police force, He Xiaohui retrieved the shoe found in the river beach, and took the evidence recovered from Wu Qingxiang's house to go to the police dog training ground. He saw Lu Yingwei sitting at his desk in a daze, so he called:
"Brother Lu, let's go with me to check your shoes."
"No, you want to link that drunkard Yang Hui with the shooting. I don't believe it." Lu Yingwei waved his hands and said.
"Oh, believe it or not, you'll know if you go there." In the end, He Xiaohuisheng forced Lu Yingwei to the police dog training ground.
After they explained their purpose to the trainer, the trainer quickly took out Ali, who was on duty that day. The trainer first asked Ali to smell the shoe found on the river beach, and then opened the bag containing Yang Hui's shoes.
As soon as the bag was opened, Ali screamed excitedly. The trainer put the mouth of the bag under Ali's nose, and Ali screamed even louder.
"These two pairs of shoes belong to the same person." The trainer said to He Xiaohui and He Xiaohui with certainty after seeing Ali's reaction.
"What? Are they really the same person's shoes?" Lu Yingwei couldn't believe what was happening in front of him.
"It's unmistakable. My communication with Ali is very tacit and I understand his reaction very well. The result is absolutely unmistakable," the trainer said.
"Okay, Xiaohui, you have made a great contribution today." Lu Yingwei said to He Xiaohui with his thumb raised.
"How about it? My intuition is right." He Xiaohui said proudly.
He Xiaohui took out the cloth bag again and said to the trainer:
"The smell here is very familiar to me, but I can't remember what it is. I wonder if a police dog can find out what kind of smell it is?"
"Oh, this is a bit difficult. The police dog can't speak. He can only judge whether the smell is the same or trace the source of the smell. It is really difficult to ask him to identify it."
"It doesn't matter, just give it a try. It doesn't matter if you can't find it."
"You can try it, but we have to go to the sample room. There are dozens of common items there. Maybe Ali can identify what was in this bag."
The three of them came to the sample room and saw forty kinds of common smelly things placed on the walls of the sample room, including food and cosmetics, medicines and drugs, and some daily necessities. On each sample there was
There was a number plate hanging on it. The trainer opened the mouth of the bag, let Ali smell it, then pointed to the sample on the wall and patted Ali's head.
Ali walked back and forth in front of the sample wall and smelled it. After walking back and forth several times, he returned to the trainer, smelled the smell in the bag again, and then returned to the sample wall and smelled it back and forth. Suddenly Ali
Li called out softly a few times, bit off one of the number plates, returned to the trainer and handed it to him. The number 26 was written on the number plate.
The three of them walked to the sample wall with their number plates and saw a pistol placed in sample box No. 26.
"Gun? Can Ali smell the smell of a gun?" Lu Yingwei asked in surprise.
"Yes, guns have a smell. All guns have been tested before leaving the factory. They will have the residual smell of gunpowder, plus the smell of firearm lubricating oil, so the gun has a mixed smell of gunpowder and lubricating oil."
"Oh, I said the smell of this bag is so familiar. It turns out to be the smell of guns." He Xiaohui said to herself.
"Xiaohui, that's right. If you work harder, Ali will be unemployed." Lu Yingwei joked without losing the opportunity.
"This is the special feeling of a criminal police officer, hum!" He Xiaohui smiled proudly.
Su Zhengyang was also shocked when he heard what He Xiaohui and Lu Yingwei had discovered.
"Yang Hui? How is that possible? That weak technician, that drunkard. This really overturned my entire understanding of people."
"Master, are you praising me or criticizing me?" Seeing Su Zhengyang's confused look, He Xiaohui asked carefully in a low voice.
"Praise, of course it is praise. You two have made a great contribution this time. I will take credit from you when the case is concluded."
"Captain Su, this is all the result of Xiaohui's nose."
"Nose, what's wrong with the nose?"
"Fuck you." He Xiaohui pushed Lu Yingwei coquettishly.
"If Yang Hui is the murderer of Wang Sheng, have you ever thought about why he killed Wang Sheng?" Su Zhengyang asked.
"Master, I've thought about this issue, but I can't connect these two people no matter what," He Xiaohui said.
"Also, how did Yang Hui get the gun? Even if he wanted to buy it, he must have channels. You said he is a technical person, how could he know the gun seller?" Lu Yingwei said.
"Did we meet on the Internet? These technical men are all keen on surfing the Internet." He Xiaohui said.
"But we didn't find the computer when Yang Hui arrived at his home."
"Maybe he is surfing the Internet at work?"
"Well, I think it's necessary for you to go to his work unit to understand the situation. But last time he confessed that the work unit fired him. Alas, I really regret letting him go now." Su Zhengyang sighed.
"It's understandable that Yang Hui had the motive to kill Ding Peng, but why did he want to kill Wang Sheng?" Lu Yingwei said.
"Yes, why did he want to kill Wang Sheng?"
"And that Dai Tonghe, Wang Sheng was killed by Yang Hui after receiving a call from Dai Tonghe. Could this be related to Dai Tonghe?"
"If this matter has anything to do with Dai Tonghe, then what is the relationship between Yang Hui and Dai Tonghe?"
"Wang Sheng received a call from Dai Tonghe at 9:19 and was killed between 11 and 12 o'clock. What did Wang Sheng do in these two hours?"
"So the whereabouts of Wang Sheng and Yang Hui that night need to be further investigated to see when they met."
"Team Su, I have an idea. Since Wang Sheng's murder is related to Yang Hui and Dai Tonghe, is this case also related to Ding Peng's murder?"
"I feel there may be a connection here, but we still don't understand some situations and can't connect the two things."
"It cannot be ruled out that there is a direct conflict between Wang Sheng and Yang Hui."
"And where did Yang Hui go? Did he run away? Or was he dead?"
"Well, so now we have to start the investigation surrounding Yang Hui." Su Zhengyang thought for a while and continued to arrange the work.
"Xiao Lu and Xiaohui, go to Yang Hui's unit to understand the situation, and then talk to Wu Qingxiang and ask her if she knows about Wang Sheng. I will arrange for Guan Jie and others to investigate Wang Sheng's family and the source of the gun.
In addition, I will immediately apply to arrest Yang Hui."
