Case closed

As for Li Weimin's parents, they are honest rural people. They were very sad to hear the news of their son's death, but they didn't know anything about Li Weimin's social relationship, let alone Li Weimin's conflicts with others.

The company said that Li Weimin became a project manager at the beginning of the year, that is, half a year ago, and had been in charge of the development of a game software during his lifetime. This software is currently competing with a new company called "Fonda" Technology.

Jiang Shan froze for a moment, "Which company are you talking about?"

"Honda, a small company that was just registered a year or two ago was not competitive at first, but in this software development, there is a big innovation. It is said that the planning copywriting is more competitive, so now Wei Teng and Hongda Let's compete for the right to develop this game."

Jiang Shan: "In Li Weimin's study, I saw a lot of information about software development, including the details of Honda's internal software development. At first, I thought it was a business cooperation between the company. Why are Li Weimin and Honda still involved. "

Jiang Shan went to Li Weimin's house again, packed Hongda's documents in a physical evidence bag, and personally visited Hongda's boss, Chen Dong, and let him read the materials in Li Weimin's study. Chen Dong was shocked, " These are all internal materials of our company, and they have not been leaked to anyone except the company we are trying to cooperate with, so there must be a traitor inside the company."

Jiang Shan looked at the other party, and was at a loss for words for a while, Jiang Shan pointed to Li Weimin's photo, "Then do you know this person?"

Chen Dong: "This is our company's competitor, Wei Teng's project manager, Li Weimin."

Jiang Shan: "Besides being competitors, do you two have other personal relationships?"

Chen Dong: "It's just acquaintance in the mall."

Jiang Shan: "We found the record of your call to him half a month ago in Li Weimin's mobile phone communication. Would you please disclose the content of the conversation?"

Chen Dong: "Actually, I didn't say anything. It was just a psychological warfare between competitors to test each other."

At this time, a staff member rushed over rashly from outside, "Mr. Chen, Madam is here to see you."

Chen Dong's tone was a little serious: "Didn't you see that I'm busy, let her wait for me in my conference room."

Jiang Shan wanted to continue asking about the situation, but a woman rushed in directly, "I didn't come to your office directly, this time you were fascinated by some vixen, and you drove me to the conference room..."

Chen Dong's girlfriend pushed the door open, and when they saw Jiang Shan, both of them were stunned. Jiang Shan could only say in embarrassment: "Mr. Chen's wife is really a soft-tempered person..."

Chen Dong: "Hehe, this is my girlfriend, the police officer laughed at me."

Jiang Shan left immediately and returned to the police force. Seeing Lin An sorting out the information about the case, Jiang Shan glanced over and picked up a photo, "What is the relationship between this woman and the deceased?"

Lin An: "This is from the second team, Li Weimin's girlfriend Xia Shan."

Jiang Shan: "No way, I just came from Hongda's boss, Chen Dong, and his girlfriend is the woman in the photo."

Lin An was stunned for a moment, and Jiang Shan immediately went to the technical team, "Do you have Chen Dong's cell phone? Immediately call up all the records of his calls and text messages with the outside world for the past month, and immediately monitor Chen Dong's cell phone. How long will it take to complete."

Lin Yao: "If you monitor, you can do it today, but the previous record will be adjusted tomorrow."

Jiang Shan: "Okay, let me know as soon as the records are retrieved tomorrow."

Lin Yao: "I know Team Jiang."

Jiang Shan almost forgot: "By the way, Xia Shan is in a relationship with Li Weimin and Chen Dong at the same time. When the time comes, we must monitor the content of the phone calls from her." "Okay."

Jiang Shan really doesn't understand, what's going on with this Xia Shan, the same girlfriend?Is it Xia Shan's problem, or Chen Dong's and Li Weimin's?

The next day, news came from Lin Yao. In Chen Dong's communication records, in addition to regular business contacts, there were three suspicious numbers in the past half month: the number in May NO.19 Shanxi called once , On May 25, the number in Shaanxi was called once, and the most recent one was the number in Gansu on May 31.

Jiang Shan: "Can we investigate the holders of these numbers?"

Lin Yao shook her head: "I have already checked these numbers, and they are all without real-name registration. I guess they were bought casually on the roadside, and there is no way to find them."

Jiang Shan: "In the past two days, has Chen Dong's mobile phone called from a similar number?"

"Not yet," Lin Yao thought for a while, "Team Jiang, maybe we are overthinking these numbers, maybe these numbers are harassment numbers or something."

Jiang Shan didn't say a word: "Let me think about it again, Chen Dong's cell phone has been monitored all the time."

"Okay." Zhou Ying thought for a while and continued, "Team Jiang, Chen Dong's mobile phone number, and among the people I often contact, there is also Li Weimin's girlfriend Xia Shan. The tone of the two people's phone calls is intimate, and Xia Shan asked Chen Dong Dong, did Li Weimin's death have anything to do with him, but Chen Dong denied it and reprimanded Xia Shan."

Jiang Shan went back to the office and looked at the map: Shanxi, Shaanxi, and Gansu. If we assume that the holders of these three numbers are the same person, it means that this person has been moving westward away from Ningyuan City. Why change it? Number to contact Chen Dong once?If we assume that the holders of these three people are three people, why call Chen Dong in turn?

Taking advantage of Chen Dong's absence, Jiang Shan went to Chen Dong's company again and stopped an employee at random.

Jiang Shan: "Do you know the woman in the photo?"

The other party: "Yes, she is our boss' girlfriend."

Jiang Shan: "How long has your boss been dating this woman?"

The other party: "I came to the company in July last year. Anyway, she has been the boss's girlfriend since then. It's been a long time since I heard about it. I don't know the details."

Jiang Shan continued to ask: "Do you know that your company and Wei Teng are competing for software development at the same time?"

The other party was obviously shocked: "How can our company have the ability to compete with Wei Teng."

Jiang Shan was stunned again: What's the matter with Chen Dong? Does this kind of competitive relationship need to be kept secret? Wei Teng knows it, but his company employees don't know it?

Lin Yao called, "Team Jiang, I called Chen Dong from an unfamiliar number again, this time it's from Qinghai."

Jiang Shan: "Do you know what you said?"

Lin Yao: "I know, but both of them seem to be avoiding something on purpose, and what they said is rather vague, and I don't quite understand it."

"Okay, I'll go back right away." Jiang Shan hung up the phone, turned around and told the staff of Hongda Company, "Thank you for today, but please keep the matter of today confidential, it is related to the key for our police to solve the case." Seeing the other party nodded half nervously and half scared, Jiang Shan left.

Back at the police force, Jiang Shan went to Lin Yao to get the audio of the conversation between Chen Dong and Qing Hai's number.

"Hey, it's me."

Chen Dong: "The rumors are tight recently, so don't contact me yet."

"Well, I'm going to go west and go out of bounds to avoid the limelight, but I don't have enough money."

Chen Dong: "I don't have much either. I'll contact you when I have raised enough in the past two days."

This audio sounded like the other party had done something to go abroad, and it seemed that Chen Dong was making a deal with someone, but there was really no concrete and substantive evidence, so the vague audio was used as evidence. Jiang Shan himself felt that there was no credibility.

Some people in the team were sent out by Jiangshan to investigate Li Weimin's suspicious and two-footed girlfriend. Li Weimin is a rigid programmer. He has not been a project manager for a long time, and he basically has no enemies. To be precise, he has conflicts. Not at all.

Jiang Shan is going to investigate Chen Dong specifically. After all, it is really difficult to break through on the side of the deceased, and there are too few conflicts, so he can only find other breakthroughs.

The technical team had an analysis of the two half shoe prints found in the window.

Zhou Ying: "Team Jiang, the shoe prints are ready. They are 07-style leather shoes uniformly issued by the military academy. For men, size 42 or 43."

Jiang Shan: "Are you sure?"

Zhou Ying: "Our technical side is based on the traces left and the restored sole pattern. It cannot be said to be 100% sure, but it can basically be guaranteed."

Jiang Shan called Lin An, "Immediately investigate Li Weimin, Xia Shan, and Chen Dong's network, whether there are any graduates from military academy, including friends, and classmates from childhood to adulthood." Lin An got the order and began to visit.

After the police officer who investigated Li Weimin, or Chen Dong's girlfriend, returned to the team, he reported the details of the visit to Jiangshan.

"Team Jiang, this Xia Shan said that she was originally Chen Dong's girlfriend, but she broke up with Li Weimin some time ago, and then they broke up at the beginning of May."

Jiang Shan: "I guess Xia Shan won't be able to ask anything. Chen Dong should have taught these words long ago."

Lin An also received a lot of feedback, and handed Jiang Shan a set of photos after returning to the team.Lin An: "Team Jiang, this person's name is Wang Chuankai. He was a child of Chen Dong. He was originally studying in the military academy, but because of fighting, he was expelled from the military academy. After that, he didn't have a regular job and has been hanging around with Chen Dong."

Jiang Shan: "Do you know where his home is?"

Lin An nodded: "I know the general location. It is said that it is in the old commercial street. I have to find out which one it is."

Jiang Shan got up and picked up his coat, "Come on, let's visit Wang Chuankai's house."

Jiang Shan only brought Lin An to the old commercial street where Wang Chuankai's home is located. This area was the most prosperous and tallest block 20 years ago. With the rapid development of these years, this area has also become a peaceful The old neighborhood of the original city.

Lin An took the photo and asked the aunt nearby, "Auntie, do you know this person? His name is Wang Chuankai. Do you know where he lives?"

Aunt: "Yes, Xiao Kai. Our street is called Qianjie. He lives in the back street next to him. There is a tailor shop. The one behind the shop is his home."

Lin An: "Hey, thank you."
