Mao Qiang, male, 38 years old, from this city, currently residing in ......

"Hey, this is not the place where the female deceased appeared with the fat man at that time......"

When Guan Zhonghua saw the address, he instantly recognized that this was the residential building where Lin Yuan delivered food to Ning Cheng and helped Ning Cheng eat chicken, and this Mao Qiang actually lived there.

Who is Mao Qiang?

It was the person who played with torches ten years ago to play with death, because it was manslaughter, well, to be precise, it was the crime of negligence causing death, and he was sentenced to six years, deducting holidays - that is impossible, Huaxia does not deduct holidays, and only good behavior can reduce the sentence, and this Mao Qiang behaved averagely, and he was released after six years in prison.

And after being released, his life seems to be very nourishing, he set up a factory, and now the business in the factory is very good, and he has become a big boss with a net worth of tens of millions, and the house he lives in is also his own.

Guan Zhonghua drove to Mao Qiang's residence, and asked Ning Cheng some details by the way, maybe there was something to discover, criminal investigation work is like this, that is, to find problems in small details, maybe this small detail has been seen many times, maybe it was not found before, and this time it was suddenly discovered.

When he came to Mao Qiang's residence, he found that Mao Qiang was on the floor three floors up from Ning Cheng.

"Ding Dong!"

Guan Zhonghua rang Mao Qiang's doorbell.

"Who. ”

A male voice came from inside, but this voice was not very high, if it weren't for Guan Zhonghua's sensitive ears, he might not be able to hear it, this sound was a natural sound after some people heard the doorbell.

At this time, the door did not open, and a male voice rang on the doorbell: "Who are you?"

This should be a kind of video doorbell, installed directly in the position of the cat's eye, the outside is the camera, the inside is a screen to see the outside, whether it is outside or inside, there are speakers and microphones, and you can talk directly.

Generally, this kind of video doorbell can also be connected to the mobile phone, even if the person is not at home, you can know who is coming, you can also use it as a surveillance, and you can store video recordings.

This kind of video doorbell has several advantages, firstly, it is impossible for the thief to open the door by poking the cat's eye, secondly, he does not have to lie on it to look at the people outside, and thirdly, if there is a bear child to ring the doorbell, you can write it down, of course, there are two or three households on the first floor of this kind of residential building, and basically there will be no bear child to do such a thing, but other places can.

There is also a very important benefit, that is, there is no longer a fear of a killer with a gun against the cat's eye, and then kill himself with a shot, well, this world is very dangerous, such a thing can happen, safety first, this kind of video doorbell must be installed.

Wait, in that case, just check the memory card of this video doorbell and you'll know who's coming.

Guan Zhonghua kept an eye on it, ready to wait for an opportunity to take down the memory card of this doorbell.

"I'm Guan Zhonghua, this is my police ID, I'm here to find Mao Qiang to confirm some things, are you Mao Qiang?" Guan Zhonghua directly took out his police ID card and showed his identity, he came here to ask about that kind of scar, if Mao Qiang is afraid, it means that it has something to do with the current matter.

The door opened, and inside was a somewhat greasy uncle, who looked at Guan Zhonghua for a while, and then said, "Officer, is there anything wrong? Since I was reformed, I have always been a good person who abides by the law and abides by the law. ”

"Don't worry, I'm coming to you today to ask about something, according to your ten-year confession, your whip has been burned by you, right? Guan Zhonghua asked.

"Whip, what whip?" Mao Qiang was stunned for a moment and asked.

"It's the whip you use when you're abusing a woman. Guan Zhonghua glanced at Mao Qiang and said quietly.

"Oh, that's, yes I burned it all because I was afraid of being found out, so I burned it, but then I went and turned myself in. Mao Qiang remembered and said immediately.

"Can you describe what that whip looks like and where you bought it? Guan Zhonghua said.

"What, officer, you also have this interest?" Mao Qiang was stunned for a moment, looked at Guan Zhonghua, and looked ambiguous.

A black line appeared on Guan Zhonghua's forehead, and then said: "I was investigating a case recently, and there was a similar situation, so I came to ask you, this matter will not have anything to do with you, right?"

Guan Zhonghua deliberately showed a suspicious look of Mao Qiang, and his words were also very tactful, without saying specific details, he wanted to test Mao Qiang's reaction.

"Why, I haven't touched those things for a long time, it must have nothing to do with me, as for what the whip looks like and where I bought it, officer, it's been ten years ago, I bought it in a random store, I can't remember it clearly, really, I really can't remember. Mao Qiang immediately shook his head and said, very nervous, but this nervousness is not afraid of being discovered, but just afraid of being involved in the relationship.

At least, on the surface, Guan Zhonghua's observation is like this, if he is wrong, it can only show that this Mao Qiang is not ordinary, but he feels that this Mao Qiang is really ordinary.

Next, Guan Zhonghua made an excuse and went into the house to take a look, Mao Qiang did not refuse, he was not so wary of Guan Zhonghua, which also showed that he might not have any problems.

After observation, Guan Zhonghua didn't find anything, and he also took down the memory card of the video doorbell by the way, and then inserted a card reader, this card reader is not just a card reader, as long as there is a memory card inserted, it will immediately copy the content, support a variety of card formats, and also support USB interface, etc., which is a very convenient auxiliary tool.

After doing these things, Guan Zhonghua left, pressed to Ning Cheng's floor, and chatted with Ning Cheng.

After chatting with Ning Cheng, there was an unexpected gain, that was when he took out the photo of the female deceased, he showed Ning Cheng if he had seen her, and Ning Cheng recognized it at a glance.

"I've seen it, this woman once took the elevator with me, she pressed the same floor as me, but she said that she pressed the wrong floor, and then pressed the next floor, and the day when Lin Yuan came to deliver takeaways, after Lin Yuan left, I saw her come out of the staircase from the cat's eye when I closed the door, and then walked to the elevator and pressed the elevator down, she is so strange, obviously not this floor, you have to go up and down the elevator on this floor, there must be something catty. ”

Ning Cheng put on his glasses in Conan's posture, looking like I was a detective.

“...... , Why didn't you say such an important thing earlier?" Guan Zhonghua was a little speechless, you never talked about such an important clue.

"What did you say earlier?" Ning Cheng didn't understand, what did you ask me to say earlier.

Guan Zhonghua said angrily: "It's her getting on and off the elevator here, and she appeared immediately after Lin Yuan left, which means that Lin Yuan and she haven't met here at all." ”

"I don't know if you want to ask her, when they came to ask me, they asked me when Lin Yuan came over, and then when he left, I didn't look at the time, plus it's been a long time, how can I know." Ning Cheng said directly and angrily, this is to blame me, if you want to blame, blame yourself.

“......”

Yes, why do you want to ask about her, Ning Cheng is just Lin Yuan's time witness, and the people who came to question must have asked about Lin Yuan, not about the female deceased, those people, they won't ask more about this matter.

Hey, it seems that it is better to find a way to get the detachment in this matter, otherwise it is not a solution.
