The only thing that can be confirmed now is that the murderer used Chen Youfeng's mobile phone to send a message to the driver Gong Libai through social software, asking him to pick up the car and wash the car overnight, with the purpose of destroying the evidence left on the car.

Because the murderer knew that the fishing rod set up on the edge of the artificial lake would definitely allow the police to find Chen Youfeng's body in a very short time.

When I walked out of the interrogation room, Li Meng was standing outside the door, although she did not participate in the interrogation process just now, but she stood outside the interrogation room, and she saw the whole process.

"Did he lie?" I asked after a pause.

Li Meng shook his head and said to me seriously: "At least all the questions you ask him, he answers the truth. ”

I sighed, I really didn't know what to do with this Gong Libai.

Is he really stupid or fake, and what role does he play in this case, is he really just a pawn used by the murderer to destroy evidence?

At this time, Li Meng suddenly raised his head and said to me: "We should still use the criminal investigation methods we are most familiar with to find clues from the deceased. ”

I looked at her in a daze and said slowly, "Tell me about your criminal profile." ”

Li Meng took a deep breath, spit out slowly, and said quietly: "The murderer is a man, and he has no stable occupation, or only a temporary occupation. The murderer and Chen Youfeng have a deep hatred, but it is not necessarily that he himself has a grudge against Chen Youfeng, it may be that the murderer's relatives have a grudge against Chen Youfeng, or the murderer's relatives were seriously injured by Chen Youfeng, so the murderer will come to take revenge and beat Chen Youfeng to vent his anger. The murderer knew Chen Youfeng's lifestyle very well, knew his address, and knew his preferences. So he must have worked with Chen Youfeng, and Chen Youfeng will never doubt him. ”

After listening to Li Meng's criminal profile, I nodded deeply, because according to the clues I have so far, I also think so.

However, after Li Meng systematically told me the profile of the murderer, I suddenly thought of something.

Liu Erzhu has not yet investigated, if Chen Youfeng is dead, then Liu Erzhu is the biggest beneficiary, and Liu Erzhu is also very consistent with Li Meng's criminal profile, except professionally.

It seems that it is necessary to meet the marketing manager named Liu Erzhu tomorrow.

At the same time, Jiang Tingbai and the technical team have conducted a careful on-site investigation of Chen Youfeng's residence, and although the scene has been carefully cleaned, they still extracted a small amount of blood stains on the sofa.

If it weren't for the fact that they were holding a professional exploration tool, a biological sample discovery machine, they would have ignored this bloodstain that was almost invisible to the naked eye.

The blood stain is dripping, which means that the blood stain is not a blood stain caused by direct contact between the bleeding point and the sofa. Rather, the bleeding spots spilled blood and dripped onto the couch.

Moreover, Jiang Tingbai also found that around this bloodstain, there were many single dripping blood stains in a small area, which was a very obvious splattering blood stain.

Although it is a blood spatte, unlike the blood splattered by a sharp object that punctures an artery, the blood stain on the sofa bleed very little.

If it is associated with the facts of the case in which Chen Youfeng was beaten, it is very likely that Chen Youfeng was beaten and blood splattered from his mouth.

After DNA profiling of the blood samples collected from the scene, it was determined that this was Chen Youfeng's bloodstains.

In this way, it is confirmed that this is the scene of the first crime, that is, the place where Chen Youfeng was severely beaten.

This is a major discovery.

But on the other hand, the technical team also carried out a careful trace inspection of Chen Youfeng's car, because the car had just been carefully cleaned, so the technical team did not find any clues.

Fingerprints, footprints, sweat, hair, nothing else was found.

Xue Hang is also verifying the vehicles used by the killers and investigating the surveillance footage along the road.

Similarly, Lin Zifan is also assisting in the investigation, and at the same time investigating Chen Youfeng's personal information, including which companies he is involved in foreign cooperation, hoping to find some clues from here.

After we confirmed Gong Libai's transcripts, we let him go home, and there is no substantive evidence at the moment, and it is useless to continue to detain him.

It's dark today, and nothing can be done other than the work we can do through the systematic investigation.

Tomorrow, I'm going to take Li Meng to meet this marketing manager named Liu Erzhu for a while.

……

At dawn the next day, after a brief bite of breakfast, I took Li Meng and ran to Fishga Network Technology Company.

Today is the second day after Chen Youfeng's death, that is to say, the marketing director of Fishga Network Technology, the big celebrity in the eyes of the boss, and the thorn in the eye of his colleagues, has not come to work all day.

Moreover, someone must have contacted Chen Youfeng and asked him why he did not come to work.

Moreover, Chen Youfeng must not have answered the phone.

It is precisely because of this that after a whole day of fermentation yesterday, coupled with the fact that our police have been in and out of Fishgar Network Technology Company for investigation, there will definitely be a fire of gossip within the company.

Because once someone suddenly loses contact, then everyone's first reaction is that something happened to this person.

Especially Chen Youfeng, everyone is looking forward to his accident every day.

We met Liu Erzhu, the marketing manager at the gate of the company, he had just walked out of the door, it seemed that he was in a good mood today, and he always had a smile on his face.

Although we have no way of knowing whether his smile is because of rumors in the company that Chen Youfeng has an accident, or if this is what he looks like.

Because we learned from the dialogue with Chen Xi and Peng Xiaoping, employees of the marketing department, that Liu Erzhu is very popular in the company, and everyone's evaluation of him is also amiable, has a very good relationship with employees, and often eats together.

"You're Manager Liu Erzhu, right?" Li Meng and I walked up to Liu Erzhu and asked.

"Are you ......," Liu Erzhu asked us with a smile on his face.

"We are the criminal police of the Ningzhou Public Security Bureau, and there are some things I want to know from you." I said earnestly and showed my police ID.

Liu Erzhu blinked and asked us in some surprise: "I think it must be something related to Chen Youfeng." ”

I nodded and acknowledged.

The smile on Liu Erzhu's face became even brighter, he looked at the horizon not far away, sighed, and then said with a slow smile: "It's fun to have friends from afar!" Two police comrades, I'm going to the café for a drink, why don't we go there and talk. ”

There are many people in the company, and it is a holy place where the fire of gossip burns, and it is indeed a very good plan to go to the café to investigate the situation.

Afterwards, we followed Liu Erzhu and walked to a café diagonally opposite the company.
