Song Min's wife sat on a blue plastic chair in the hall, and when she saw Chen Mu coming out, she quickly stood up, "Captain Chen......"

Chen Mu raised his hand and motioned for him to sit down, "Do you have anything to do?" ”

"Today I cleaned the house and broke the rose pot on the windowsill, and I found this thing when I cleaned it up."

Song Min's wife handed over the things in her hand, which was a key in a plastic bag, and the handwriting on it was clearly visible.

“3—1？” Chen Mu looked at the appearance of the key, the key handle the size of a fingernail, the slender key, and behind it was a string of numbers of unknown meaning.

He immediately asked, "Does Song Min have the habit of exercising, taking a bath, or playing ball?" ”

"No, but ......," Song Min's wife recalled, "he got a gymnasium membership card a month before the accident, and I also said that he spent money indiscriminately, and he was so busy with work that he couldn't go a few times." ”

Chen Mu understood, he pinched the key and gave it to Lin Jialuo behind him: "You go and see what the gymnasiums near Song Min's house are, and then go and ask." ”

Lin Jialuo nodded, turned around and left.

Song Min's wife still doesn't understand, "Captain Chen, this is ......"

"It's nothing, he does his own thing, sister-in-law, I want to ask you something." Chen Mu led Song Min's wife to sit in the office inside, "Does Song Min usually interact with any young girls?" ”

Chen Mu said this straightly, and Song Min's wife's face turned blue all of a sudden, "Captain Chen, I admit that our old Song is blackmailing, but he helps when he is free at home, and he doesn't drink or play cards, such a person, you say this......"

Speaking of the back, Song Min's wife was so aggrieved that she couldn't go on, and she choked on her chest in one breath.

Chen Mu was also helpless, so he pulled out a tissue and handed it over, but people didn't answer it at all. He could only tell the truth, "Sister-in-law, I'm not saying that Song Min has anything wrong with you, it's that he's helping a little girl and doing something." We must find out this little girl now to know who Lao Song provoked and lost his life. ”

Song Min's wife looked up, with tears on her face, "What do you mean?" ”

Chen Mu could only repeat what he had just said again, and at this time Song Min's wife came back to her senses, she took the tissue, cleaned herself up, and said after a while: "The two of us have sponsored a girl in the mountains before, she is a sophomore this year, and she is admitted to this city." When I first went to college, I still corresponded with my family, helping me or something, but I don't know how this year, I haven't been here once. Because Song Min was doing all this, I nagged a few words, and he was still angry with me, saying that it was not easy for people or something. ”

"Do you have a contact number?"

Song Min's wife hurriedly took out her mobile phone and flipped out a number from it.

Chen Mu thought to himself that there was hope now.

Lin Jialuo went to the gymnasium with Ruo at this time, and after talking to the front desk, she took Lin Jialuo to 3-1, and the key opened the door, and there was only a USB flash drive and a few pieces of paper inside.

The colleagues behind him were excited: "I can't run away now." ”

Lin Jialuo's mood is not so good, according to Jian Ru's confession, Zhang Xiao is going to keep accounts, and the video is available, so what about the account book?

Where is this thing?

Lin Jialuo first put the USB flash drive and a few pieces of paper in the physical evidence bag, and then said to the front desk: "Ask, has anyone else come over to take the contents of this locker?" ”

The front desk recalled, shaking his head.

Lin Jialuo looked at the noisy crowd around him, and in a place with a large flow of people, it was certainly easy to save things, but ......

This lock can be easily opened by anyone who knows a little.

If there is no goal......

Lin Jialuo still said: "Please give me the surveillance video of all the cameras in your gymnasium in the past seven days." ”

"Wait a minute."

After Lin Jialuo got the things, he quickly rushed back to the police station, and together with Chen Mu, he used the number on the back of the key to open the file in the USB.

And click on it inside, there are indeed indecent videos, but there is only one actor.

Chen Mu looked at this thing and listened to Lin Jialuo's report, "That means that the person who killed Song Min processed these videos and took Zhang Xiao's account book." ”

"That's right." Lin Jialuo clicked on the surveillance video he brought back, "I thought about it for a while, he may not know where Song Min hid his things, so if he wants to find it, he needs tools, and he needs to rummage through lockers one by one, and it will take time." In this case, he must have an identity that does not arouse suspicion. ”

Lin Jialuo opened a screen, which switched to a man, a man in an electrician uniform and a peaked cap.

"I think this person is very suspicious."

"Why?"

"I later checked with the front desk, and she said that this electrician master had been in it for a long time, and when he came out, his backpack was bulging, but his appearance was a little scary, so I didn't dare to ask more. And when he went in and out of the front desk of the gymnasium, he walked with his head down, with a sense of anti-reconnaissance. ”

"Scary, what's a scary law?"

"There's a scar on his face, but it's on the left or the right, the front desk can't remember it anymore."

Chen Mu patted Lin Jialuo's shoulder, "Yes, the progress is very fast." ”

Liu Binglei held her mouth on the side, "I'm making rapid progress." ”

"Yes, you're fast, too." Chen Mu was like an old father comforting his daughter, "Now, let's sort it out." ”

Chen Mu began to draw a straight line on the whiteboard, and then marked the time point.

First of all, at one o'clock in the afternoon on the day of Song Min's death, he went to the property to get the key, saying that he needed to return to the scene because of work. The time we found out was two o'clock in the afternoon the next day. According to Yan Lingyun's time of death, Song Min's real time of death was between six o'clock in the afternoon and seven o'clock. Because the whole community monitoring is being updated, we have no way of knowing who has entered the community after 4 o'clock in the afternoon. Chen Mu paused, "During this time period, someone entered the community, talked to Song Min, gave him water doped with tranquilizers halfway, and may have looked through Song Min's mobile phone and learned about the existence of the gymnasium." Then ......"

"Kill Song Min at six o'clock in the evening?" Liu Binglei replied quickly.

But Chen Mu stared at the line, "Would you talk for so long about the person you want to kill?" ”

Why did it take so long? What happened in between?

Chen Mu couldn't figure it out, there were only the two of them at the scene, and if it was faster, it would be easier to escape, so why bother?

This doesn't make sense.

Liu Binglei looked at the large blank space, "Maybe he has something to delay?" ”
