The photo was taken a few days before Ma Chaoxin was killed, looking at the photo of the woman, Luo Cheng always felt where he had seen it, but he couldn't tell where he had seen it, it was very familiar.

Luo Cheng walked into the office with doubts, Dai Lin made more discoveries, he extracted three completely different fingerprints from Ma Chaoxin's house, one was Ma Chaoxin, and the other two fingerprints did not have a library, which means that they have no criminal record, and it is unknown who they are.

Li Xiao grabbed two blurry images, one tall and one short, from the surveillance of a nearby commissary, which were not of high value.

So far, the police have not caught any tricks on Li Shengyu, not even a picture, and he doesn't know what he looks like now.

The cunning of the opponent also makes everyone feel the thorniness of the problem.

Luo Cheng took out the map, he had looked at it several times and never understood it.

"This is a brief tactical map, but the content is not simple, I went to check these times, this is the time required to pass this road, the murderer only needs two and a half minutes from the end of the crime to completely escape the scene, and the maximum possible avoidance of the monitoring probe, if you change the means of transportation halfway then the escape time is shorter, faster, which also shows that the murderer has done a detailed investigation of these targets, it can be seen that the murderer's tactical literacy is quite good, and has a very high sense of anti-reconnaissance, Combined with these characteristics, I think this murderer should be Li Shengyu, the characteristics I just said are also in line with his habits as a professional soldier, but I don't know what these locations mean to him? ”

Luo Cheng expressed his opinion.

Everyone can see that these four locations should be the plan of action map, and the person who drew this map must have ulterior motives.

He Zhonghua thought for a while and said: "If this is left by Li Shengyu, then his target should be Qi Hong, but now that Qi Hong is dead, are there people related to Qi Hong in these targets?" This is worth investigating, and there is another thing I think you should have noticed, the place chosen by Li Shengyu is not monitored around it, and it is also a weak point in police management, how did he find this place? Why is he so familiar with Qingzhou? In addition, there is another very critical point, why hasn't Lee Seung-woo committed the crime yet? What the hell happened in the middle of this? ”

One problem after another is so abruptly placed in front of everyone, if Li Shengyu has accomplices, then the case will become very tricky.

Luo Cheng took out the photo he had taken from Sun Hongmei.

"Do you know this person? I feel familiar, but I just can't remember it. ”

He Zhonghua took the photo and looked at it carefully, and felt a little familiar for a while.

"I know this person, isn't this Lu Fang?" Xiao Wu said suddenly.

Lu Fang?

Everyone suddenly realized, yes, this person is indeed very similar to Lu Fang.

Li Xiao hurriedly retrieved Lu Fang's information and said: "I found it, Lu Fang also has a sister named Lu Yan, who works in a technology company in Qingzhou, which is mainly engaged in network information technology. ”

Saying that, Li Xiao projected Lu Yan's information on the display screen.

In order to compare the differences between the two sisters, Li Xiao projected Lu Fang's photo again, the two of them are indeed very imaginary, they both have long hair, but Lu Yan is younger.

Lu Yan is a map APP, she knows the terrain of Qingzhou well, where there is surveillance, where there is police, she knows it well, this may be the real reason why the police have not been able to find Li Shengyu.

"Does she know Lee Seung Woo? Why did she help Lee Seung Woo? Xiao Wu looked at everyone suspiciously.

Luo Cheng raised his hand and said, "Who said that the murderer is Li Shengyu?" Is there any evidence? We only knew that Lee Seung Woo had entered the country, but we didn't find any evidence of Lee Seung Yu's crime, and we didn't even see him, and the man who was involved with Lu Yan could be anyone before we found evidence. ”

The discussion did not lead to any results, He Zhonghua quickly arranged the work, Li Xiao continued to collect relevant clues on the Internet, and Luo Cheng and Xiao Wu rushed to the Qingzhou Tianyue Network Information Company where Lu Yan worked non-stop.

As for the others, it is necessary to find out the real reason why the murderer circled the four targets as soon as possible, which is also the most critical and urgent, in order to send out police forces to control and squat at these four points one by one.

By the time Luo Cheng and Xiao Wu arrived at Tianyue Technology Company, they were already off work.

The two men showed their documents and showed their intentions.

The front desk said that it had been a long time since I had seen Lu Yan.

"What kind of person is this Lu Yan? Is she popular in your company? Luo Cheng asked.

"Well, it's not good, this man rarely speaks, and he has a weird temper." The front desk said.

"And who has the best relationship with her?"

"It seems to be Pan Xiaojuan from the customer service department, she is on the second floor."

"Who is Lu Yan's boss?"

"It's our manager Ye Hong."

"Okay, thank you."

Luo Cheng waved his hand and walked away with Xiao Wu, the two decided to divide labor and cooperate, Xiao Wu went to the surrounding area and immediately checked, and Luo Cheng went to contact the company's management.

Knocking on the manager's office, Luo Cheng walked in.

Ye Hong's name sounded like a man, but he didn't expect it to be a woman with glasses.

After Luo Cheng's performance, Ye Hong immediately said that Lu Yan had been fired for absenteeism for no reason.

"Lu Yan, we contacted her a few times to ask her to come to work, she said she couldn't come, let's fire her, so we fired, she is quite serious at work, and she is also very level, but she has always been silent and is a misfit person, and we are also very sad to fire talents like her, what are you looking for her?"

Ye Hong's mouth was like a machine gun, and he kept talking.

"Oh, ask her for something, when was the last time she contacted you?"

"Just last Monday, I sent her a WeChat message to keep her, and her attitude was very resolute, let us transfer the money to her account, and then there was no contact......

Ye Hong reflected in detail the whole process of Lu Yan's dismissal, Lu Yan submitted her resignation a month ago, and wrote a resignation letter at that time, it stands to reason that as long as she waits until next month, she can leave smoothly and can make compensation, but she suddenly took a week off half a month ago, and after the holiday expired, she still refused to go to work, so she was fired.

The company believes that Lu Yan is doing this to leave the company as soon as possible, she is one of the backbones of the development department, and most likely she has found a poaching of her peers.

"In this way, doesn't Lu Fang know every location in Qingzhou well?" Luo Cheng asked.

"It should be, this is their basic skill, our map is more detailed than the map of the transportation department, in addition to road information and surrounding information, such as where you want to go, we will provide the location of the corresponding gas station, hotel, hotel, even including restaurants and some entertainment venues, etc."

Luo Cheng nodded, Lu Yan should be the accomplice of the murderer, but why did they choose Ma Chaoxin?

Was it premeditated or immediate? Are they connected?

"How did she get into the company in the first place? Self-recruiting? Luo Cheng then asked.

Ye Hong shook his head and said, "No, she was introduced by our boss's friend, and the president of the Jewelry Association is called Wu What." ”

"Wu Cheng?"

"Yes, yes, it's Wu Cheng, don't tell our boss about this."

Wu Cheng, another familiar name, if it was introduced by Wu Cheng, it would be explained, Lu Fang is Wu Cheng's lover, and it is natural for him to introduce work to Lu Fang's sister Lu Yan.

But there is a problem here, it is Lin Jiadong in Wucheng, Lin Jiadong and Zhou Shuyi are in the same group, Zhou Shuyi and Li Shengyu have an ambiguous relationship, from this level, Lu Yan and Li Shengyu are enemies, even if they are not enemies, there is no basis for cooperation, right? Wang Shengyu is a murderer, why did Lu Yan take such a huge risk to get involved with him?

Or is it that everyone was misled from the beginning, Li Shengyu did exist, but it was not Li Shengyu who cooperated with Lu Yan to kill Ma Chaoxin, but someone else.

Xiao Wu found Pan Xiaojuan, Pan Xiaojuan revealed more information about Lu Yan, Lu Yan is not only withdrawn, she doesn't like to contact her, but also a little paranoid, she never mentions her family affairs in the company, in addition to this, Lu Yan has always been single, and someone once pursued her and was slapped a few times by her.

Li Xiao's side also investigated Lu Yan's situation in detail, Lu Yan did not have any relatives or friends abroad, and there was nothing abnormal in her communication records, and the last call was a call from Pan Xiaojuan, which was also confirmed by Pan Xiaojuan.

"Did Lu Yan go to work on July 21?" Luo Cheng asked.

"No, she asked for leave, saying that she went out for some business, took a day off, and came back the next day without any energy, and I don't know what she did."

Ye Hong answered Luo Cheng's question without thinking.

July 21 was the time when Li Shengyu killed the father and son of Chu Palace.
