The three of them studied the diary, contacted the 1210 case, and quickly figured out a clue.

On December 9, Jian Zheng and Ling Chunxue took and put on the pair of high heels in Wang Yan's store and left the store, and then the shoes broke on the way. It should be not far from the yard that was about to be demolished, otherwise Ling Chunxue wouldn't have been wearing broken heels all the time.

That night, Jian Zheng and Ling Chunxue took the shoes into the courtyard that was about to be demolished.

At half past three on December 10, Jian Zheng walked out of the small courtyard alone, and Ling Chunxue did not come out with him.

On December 12, the young man known as "Brother Qian" brought the pair of shoes to the store for repairs.

Mu Nan remembered that the last time he was in the detention center, Jian Zheng said that they had never left that courtyard.

Then it can be inferred that after Jian Zheng left that courtyard, Ling Chunxue left that courtyard and gave away the shoes, or someone entered the courtyard to pick up the shoes.

If Ling Chunxue had left that courtyard later, it would prove that Jian Zheng was not a murderer at all.

If someone had entered that courtyard later, it would have been necessary to find out the person, and perhaps he would have been able to prove that Jane was not the murderer, and more likely that the person was the murderer.

In the end, Mu Nan said: "I think we have to find out three things: first, whether the shoes Ling Chunxue wore that night in the video were the shoes that Wang Yan took in the store; second, who is the one named Brother Qian, and how did he get these shoes; Third, whether Ling Chunxue personally gave the shoes out, or someone else came to pick them up, and who was the person who took the shoes. ”

"You're right!" Ruan Xianchao agreed with her opinion, "I will immediately report this situation to the bureau and ask for instructions on the next step." With that, he was ready to make a phone call.

"Wait a minute!" Mu Nan immediately stood up and pressed his phone, "Let's do it first, and then report it when we have eyebrows, do you think it's okay?" ”

"Why?" This is a bit puzzling for Ruan Xianchao, who has always acted according to orders.

"This—this," Mu Nan couldn't figure out how to explain it for a moment, "because our analysis is not very mature, I don't think it's good to report it now." ”

"Well, listen to you!" Ruan Xianchao saw her eyebrows flickering when she spoke, and knew that she must have something hidden, so he no longer insisted, "Then look, what will we arrange next?" ”

"I think so." Mu Nan began to arrange the next move, "Wang Yan, you take the homeless girl outside home first and settle down." ”

"Take her home?" Wang Yan pointed to the homeless girl outside the door, her expression was very puzzled.

"Yes, take it home!" Mu Nan said very affirmatively, and smiled brightly, "You go buy a few better clothes, help her wash them well, treat her as your sister and treat her well." ”

To be honest, Wang Yan was a little unhappy, but she felt that she had no reason to refute Mu Nan, so she could only roll her eyes at Mu Nan.

Mu Nan ignored her little emotions, of course, she also knew that Wang Yan would definitely support her. She said to Wang Yan again: "You help me get two pairs of new shoes, one is the one that Ling Chunxue took that day, and the other pair is for that girl to wear." ”

"The most unlucky thing in my life is that I met you!" Wang Yan glanced at her. But she did it anyway, despite what she said.

Seeing Wang Yan take the shoes, Mu Nan said, "Let's go, you don't have to do business today, call it a day early, and we'll go our separate ways." ”

Wang Yan didn't want to close the door like this, but she felt that the matter of Mu Nan was a big deal, so she did it.

They took the shoes off the wandering girl's feet and packed them in a new shoebox. This is physical evidence, and it needs to be kept safe.

Then Mu Nan called a taxi and arranged for Wang Yan to take the homeless girl home.

After watching Wang Yan leave, Ruan Xianchao couldn't help but ask Mu Nan: "Then what are we doing now?" ”

"Let's go!" Mu Nan waved his hand, "Get in the car and go back to your bureau first." After getting into the car, she began to talk about her plans: "Let's go and call up the video of that night first, and take a serious look at the shoes that Ling Chunxue wore at night to see if they are these shoes." As he spoke, he shook the shoebox in his hand.

"After viewing the video, we went to Ling Chunxue's ex-husband's house to find out the situation, their son's name is 'Yao Qian', let's go to verify whether the 'Brother Qian' Wang Yan said is 'Yao Qian'. Ask them how they got their hands on the shoes. Wait until we have a preliminary conclusion and then report to your bureau, do you think that's okay? ”

"Yes!" Ruan Xianchao has no objection to Mu Nan's arrangement, because he also thinks so, but his opinion is to report to the bureau first, of course, he is more willing to listen to Mu Nan.

Everyone in the Public Security Bureau knew Ruan Xianchao, so it was also very convenient to do things, and the staff quickly helped them find the video file and send it to Ruan Xianchao's office.

The video file is in a USB flash drive.

Mu Nan couldn't wait to plug the USB drive into the computer, open the video and watch it.

The two of them watched it over and over again, but unfortunately, the lights were not very bright that night, and they couldn't tell if the shoes on Ling Chunxue's feet were the ones they were holding now.

Mu Nan's excitement at the beginning disappeared half of a sudden, and she asked him a little angrily, "What should I do, is there any other way?" ”

"Don't worry!" Ruan Xianchao thought for a while and said, "You wait here, I'll go and ask other colleagues to see if they have any solutions?" And with that, he went out.

But soon he came back and said excitedly: "I just asked the technical appraisal center in our bureau, and they said that there should be no problem. ”

"Really?" She suddenly became excited again, "Great! ”

"Really, they're sure of that." As he spoke, he grabbed the shoes, unplugged the USB drive from the computer, and prepared to send them to the technical appraisal center.

"Wait!" She stood up and stopped him, "You put it down first, I have something to say." ”

He was stunned for a moment, looked at her in bewilderment, and finally put the things on the desk as she intended.

Mu Nan walked over and closed the office door before speaking: "In this way, these shoes may eventually become the most important evidence, so we should be cautious, it is better to keep them with you." Do you think we can take that new pair of shoes and give them a test? ”

"That's right!" Ruan Xianchao patted his head and laughed, "These shoes are so old, the victim was still wearing a brand new pair at that time, and the new pair should be used for comparison and identification." ”

"That's right, you're more right!" Mu Nan smiled charmingly, "Besides, can't I make a copy of this video before I send it out?" ”

In the process of handling cases, all kinds of archival materials are managed very strictly, and they cannot be copied without permission, and the same is true for these electronic documents.

Now she made this request very difficult for him. He didn't want to do anything against the law, because he had never done anything wrong. But he didn't want to refuse Mu Nan, because in his heart, he never wanted to refuse any of her requests.

Mu Nan saw his embarrassment, so he looked around the room and said, "I want to have a Coke, can you go down and help me sell a coke first?" ”

He smiled wryly, "I'm sure you must have your reasons, and I know you don't want to embarrass me, but I want to be your accomplice today." As he spoke, he walked to his desk, sat down, opened a drawer and rummaged through it, took out a USB drive and inserted it into the computer, and inserted the USB disk containing the video file into the computer, "I'll help you copy this video to another USB drive, and I'll take the responsibility." ”

Mu Nan was moved again, and he blamed himself again. Why is he being so nice to himself? Why do you always trouble him when you know that you don't have that heart for him?

She said leisurely, "Thank you! ”

"Thank you? I do. After saying that, he probably felt that something was wrong again, and he smiled awkwardly again.

Then neither of them knew what to say, and the air became silent.

The document was still relatively large, and it took about ten minutes to copy.

And during this time, there has been silence.

He silently waited for the reproduction to be completed.

Silently picked up his things and walked out of the room.

After a while, he silently returned to the office.

He wanted to talk to her, but what to say?

He saw the shoes and USB drive on the desk, so he went over and took them in his hand, and handed them to her, "You have to keep such an important thing." ”

"Flutter!" She didn't pick it up, "Finally remembered something to say?" ”

"Hehe-hee-" he smirked, "you were holding me on purpose!" ”

"Alas!" She sighed, "No, I really don't know what to say to you." Actually, you get the idea! ”

He really understands.

But what's the use of understanding, I still can't restrain my desire to get closer to her, even if there is no return.

"Okay, we're friends, aren't we?" He laughed at himself, "No, I'm your boyfriend." Haha, male girlfriend! The smile is exaggerated, but it can better reflect the helplessness and desolation.

"Haha-yes, boyfriend!" The throat was so tight that the laughter was so dry. She never wanted to hurt anyone, but there were always people who got hurt because of her. Iniquity!
