Lu Yuan asked me to stay in the security room to watch the surveillance screen, and he ran alone in the direction of the twelfth floor.

By comparing it with the surveillance footage, he and I were busy for almost a full hour before finally finding the so-called dead end area.

The range where the dead angle area is located is exactly the blind spot of each layer of monitoring probes.

Judging from the situation at the scene, as long as someone is stuck in the blind spot and goes upstairs, it is impossible for the monitoring probe to capture the traces of him going upstairs.

This also somewhat confirmed my conjecture, in addition to Chang Qingshan that night, the real murderer also stayed in the office building with us.

After Chang Qingshan walked out of the editorial office, the real murderer immediately took him away and pushed him down from the top to kill, and forged the fake surveillance videotape, making all of us mistakenly believe that Chang Qingshan was the real mastermind.

Lu Yuan used a marker pen to clearly draw the scope of the monitoring blind spot on each floor, and then said with a look of disbelief: "It's so special, just such a little place, as long as you take a small step from the left and right, the monitor can record it, but that guy was stunned and escaped all the monitoring probes in the building!" ”

Indeed, the amount of error in the range marked in front of you can be described in centimeters, and if you deviate a little, the surveillance screen can capture clues.

However, this also further confirms that the real culprit must be quite familiar with this office building, not only can he easily escape the records of the monitor, but even if he uses the internal system to modify the records of the monitor, it is also easy.

It's just that after learning this truth, Lu Yuan seemed even more confused.

"Even though we figured these things out, we still couldn't find the key evidence to prove it! That guy was so well hidden, he didn't give us a chance to catch him.

Without evidence, everything you say will be overturned as a fantasy, and I am the captain of the police force, so I naturally understand the importance of evidence in a case. ”

"Don't worry, the evidence will be there, it's still the same sentence, as long as he does it, I will definitely be able to find out!" After a busy morning, it was now noon, and there were less than twenty hours left before the final time limit.

Gradually, more and more evidence began to support my reasoning, and my confidence grew, which is a good sign for now.

Maybe it's because I gambled everything, looking at Lu Yuan's anxious look, my whole person lost my previous sense of urgency.

"Put away these videos first, maybe they can come in handy when it is critical."

"Okay! What are you going to do next? ”

I thought for a moment, and then slowly said, "Let's eat lunch first, I haven't eaten since yesterday, and I'm dying of hunger." By the way, what's there to eat around here? ”

"Fuck you!" When Lu Yuan saw me like this, he couldn't wait to jump up from the chair and grab my collar: "Big brother, are you still in the mood to eat at this time?" If you don't solve this matter smoothly tomorrow, Lao Tzu will pressure you to go back to Huayuan City to recover your life! ”

I hated it when someone pinched me by the collar and tore his calloused hands away in a few clicks. "I know, there's no way around it."

"Damn, there's nothing you can't do, won't you try your best to fight for it, so I don't want to pressure you to go back?"

"Why don't you want to press me back? Isn't this the task that Lao Yan gave you? ”

"Bullshit, I still have important things to do in the future! Why do you have so much effort to care about you? ”

"Oh, what's important?"

For a while, Lu Yuan knew that he was speechless, and his whole face suddenly turned red, and the words that originally came to his mouth were also suffocated back by him.

I was most afraid that the air would suddenly be quiet, and the originally fiery scene suddenly fell silent, and even I felt very embarrassed for a while.

There was silence for a long time, and in the end, it was I who took the lead to break the silence: "So, is the thing you are going to be busy with related to Ke Mobai?" ”

As soon as the words fell, I obviously saw Lu Yuan's whole body trembling unconsciously, and there was a trace of imperceptible sadness in his originally vicissitudes of life.

Unexpectedly, after so much time, he still hasn't come out of that incident. At this point, I don't want to ask him what he's going to do, the only thing I can do now is to get the case in front of me right.

Only by doing so may be the best choice for Lu Yuan.

"Let's go eat first, and when you're full, you have the strength to do the rest of the thing."

"Okay, you're in for a treat."

", stinky boy!" Lu Yuan patted me on the shoulder, picked up the videotape on the table and slowly walked out of the security room.

The office building is near the park to be developed, and it is very desolate, except for the shop where Lu Yuan bought breakfast, there is only one Shaxian snack left.

originally thought that he could treat his stomach with a big meal, but now it seems that he can only solve it through a Shaxian county.

The store is from the Sanming area of Fujian, and the Shaxian is quite authentic, unlike the Shaxian snacks in some parts of the country.

Lu Yuan and I each ordered some staple food, plus some side dishes and stew pots, and this meal was over.

It just so happened that during the meal, Liu Hao sent me the information I had asked him to send me in the form of a text message.

"What is this?" Lu Yuan looked at the dense information on the phone screen with a puzzled expression, I hadn't had time to tell him what Song Yuan's house had found out before.

"The information of the guy who died on the train may be of some help." Liu Hao had vaguely hinted at me before that Huang Mao's background information was not simple, and I would like to see what kind of method it was now.

Huang Mao, formerly known as Ye Wushuang, male, 31 years old, a native of Z City.

When he was young, he went through the juvenile detention center for the crime of intentional wounding, and after he came out, he still did not learn his lesson, and secretly engaged in some disgraceful transactions in Z City, and his social relations were very complicated, and he had direct or indirect relations with many local underworld gangs.

Could it be that Liu Hao is referring to something unusual, referring to the complex social relationship of Huang Mao?

I used to think that the yellow hair and the mask girl might have some relationship.

But because Huang Mao is mixed in the road, he knows many people and has many enemies.

In this way, there are more people who may kill him, and if they are investigated one by one, they will definitely not be able to be investigated in ten days and half a month.

The most important thing is that I don't have time to put it off anymore! Ten days and half a month, even if there is really a result, when the time comes, this case will definitely be a matter of fact.

I pinched the bridge of my nose to force myself to calm down, and when my thoughts were cleared, I continued reading the article.

Five years ago, Ye Wushuang was sentenced to three years in prison for negligent wounding.

After coming out of prison, that guy seemed to have been rescued by a master, and his whole career suddenly improved qualitatively. From the original Ma Tsai brother to the status of a manager in one fell swoop, he even ran a bar alone in a singing and dancing alley in Z City.

It wasn't until ten days ago that Huang Mao was found tragically dead on a train, and his life came to an end.

According to the forensic examination, the deceased's body had stiff joints, purple-red spots appeared on the heart, bleeding from the mouth and nose, and there was an obvious bitter almond smell in the mouth, which was caused by cyanide poisoning. As for his killer, he has not yet been found.

The message sent to me by Liu Hao is over here, and in the above paragraph, there is a detail that I am deeply concerned about.

Five years ago, Huang Mao was sentenced to three years in prison for the crime of negligent wounding, and at the trial, the guy admitted his crime very calmly, without the slightest shirk and concealment, and after serving the sentence, his life was like a qualitative leap.

Quietly, the case from five years ago had some connection with what happened on the train.

The crime of negligent wounding became a key point in his life, and through that node, his future life made a qualitative leap, and the incident on the train was another node, announcing the end of that guy's life.

My sixth sense told me that Huang Mao's tragic death may have a lot to do with the case at that time.
