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

Chen Mu raised his hand and signaled him to sit down, "Is there anything you have to do?"

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

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

"3-1?" Chen Mu looked at the key, the key handle the size of a fingernail, the slender key, and behind it was a series of unknown numbers.

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

"Not even, but..." Song Min's wife recalled, "I applied for a membership card for the gymnasium a month before the accident. I also said that he spent money randomly. He was so busy at work that he couldn't go there a few times."

Chen Mu understood, and he pinched the key and gave it to Lin Jialuo behind him: "Go and see what are the gymnasiums near Song Min's house, 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 business. Sister-in-law, I want to ask you something." Chen Mu led Song Min's wife to the office inside, "Did Song Min usually interact with any young girls?"

Chen Mu said this, and Song Min's wife's face suddenly turned pale, "Captain Chen, I admit it, but he helps when he has time at home, and doesn't drink cards or plays like this. You say this to such a person..."

Speaking of later, Song Min's wife was so aggrieved that she couldn't continue to say anything, and she couldn't breathe into her chest.

Chen Mu was helpless and took a tissue and handed it over, but the other person didn't answer it at all. He could only tell the truth, "Sister-in-law, I'm not saying that Song Min is sorry for you, but he is helping a little girl and doing something. We must find out this little girl now to know who Lao Song has messed with and lose his life."

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

Chen Mu could only repeat the words just now. At this time, Song Min's wife came to her senses. She took the tissue and cleaned herself up. After a while, she said: "We two sponsored girls in a mountainous area. She is already in her sophomore year this year and is in the city. When she first went to college, she still had contact with my family and was in charge of the company. I don't know why this year, but I haven't been there once. Because Song Min was doing this, I just nagged a few words. He was still angry with me and said that it was not easy for me."

“Do you have a contact number?”

Song Min's wife quickly took out her cell phone and found a number from it.

Chen Mu thought there was hope now.

Lin Jialuo took Yao to the gymnasium at this time, and after talking to the front desk, she took Lin Jialuo to 3-1, the key opened the door, and there was only a usb plate and a few pieces of paper inside.

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

Lin Jialuo was not in such a good mood. According to Jian Ru's confession, Zhang Xiao wanted to keep accounts. With the video, what about the account book?

Where is this thing?

Lin Jialuo first put the USB disk and a few pieces of paper into the physical evidence bag, and then said to the front desk: "Is there anyone besides us who came here to get the things in this locker?"

The front desk recalled and shook his head.

Lin Jialuo looked at the noisy crowd around him. In places with a large flow of people, it is easy to preserve things, but...

This lock can be easily opened by anyone who understands it 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."

"Please wait."

After Lin Jialuo got the things, he quickly rushed back to the police station and, together with Chen Mu, opened the files in USB with the numbers on the back of the key.

But when you click inside, there is indeed an indecent video, but there is only one male lead.

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

"That's right." Lin Jialuo clicked on the surveillance video he brought back, "I thought about it. He may not know where Song Min hid the thing, so if he wanted to find it, he needed tools, lockers to search, and time. In this way, he must have an identity that does not cause doubt."

Lin Jialuo opened a picture and switched to a man, a man wearing an electrician uniform and a baseball cap.

"I think this person is suspicious."

"Why?"

"I later confirmed it with the front desk. She said that the electrician had been in it for a long time. When he came out, he was bulging in his backpack, but his appearance was a bit scary, so he didn't dare to ask more questions. Moreover, when he went in and out of the front desk of the gymnasium, he walked down and had the awareness of counter-scoring."

"Scary, how can you scare me?"

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

Chen Mu patted Lin Jialuo on the shoulder, "No, it's progressing very quickly."

Liu Binglei held her mouth aside, "I'm making rapid progress."

"Yes, you're very soon." Chen Mu, like his old father, comforted 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 1:00 pm on the day of Song Min's death, he looked for the property to get the keys and said that he needed to return to the scene because of work. The time we discovered was two o'clock the afternoon the other day. According to Yan Lingyun's death time, Song Min's real death time was from six o'clock in the afternoon to seven o'clock. Because the entire community surveillance was being renewed, we couldn't know who entered the community after four o'clock in the afternoon." Chen Mu paused, "At this time period, someone entered the community and had a conversation with Song Min, and gave him water mixed with sedatives in the middle. It was possible that he 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 answered quickly.

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

Why did it take so long? What happened in the middle?

Chen Mu couldn't figure it out that there were only two of them on the scene. If you were faster, it would be easier to escape. Why bother to do this?

This is not consistent with common sense.

Liu Binglei looked at the big gap, "Maybe he has delayed something?"
