Looking at Liu Hao's resolute eyes, for some reason, I suddenly felt a little distressed.

The name of the man behind the scenes, for him, the pressure is too much. If this time, I can't bring down that guy, maybe, Liu Hao will have to follow me in.

"If you can, please check the specific information of the young man who was killed at the train station as soon as possible." Based on my own inference, I feel that there may be some relationship between the youth of society and the mask woman, and if I find out the relationship between one of them, I may be able to find out the other person by the way.

Although judging from the current situation, it is very likely that the mask woman was killed, but even if there is only a 1 in 10,000 chance, I want to find her.

With one more weight, I have one more chance of bringing down the real murderer.

Lao Yan looked out the window, and took a puff of cigarette again: "The specific situation of the dead yellow hair, the police have already verified it, if you want, I will go back and tidy it up a little and give it to you, but that guy's background doesn't seem to be very simple." ”

"Not easy?" From Liu Hao's mouth, it was not easy to say such four words, and I couldn't help but ask: "How simple is it?" ”

"When you read it yourself, you'll understand what I mean."

At this time, Lu Yuan suddenly sent me a message, saying that there was a major discovery in the surveillance video of the office building, and I asked me to hurry up and take a look.

After explaining the reason to Liu Hao, this guy also asked me to hurry over to check, as for the reason for the matter here, he is responsible for investigating it clearly.

"There's only one day left, and I want you to be able to walk the talk." Looking at me, Liu Hao's eyes instantly became deep: "If tomorrow, you don't give me and the Song family a perfect answer, I can only hand you over as a suspect in this case, and what happens after that is beyond my control." ”

"Okay, I... Got it! ”

"Wait." Before going out, Liu Hao suddenly stopped me and threw me a bunch of car keys: "Just park downstairs, you can use it, you will be able to use it." ”

I glanced at the car keys in my hand, and suddenly felt a little inexplicable: "Wait, Liu Hao, when did you get on the Buick?" ”

"How can I, a poor policeman, afford it, it was Xiaoxue who asked me to hand it over to you, I went to the hospital to visit Lin Feng not long ago, and that stupid girl is still worried about you, hey, sometimes it's really a trick!"

"Yes, creation makes people." Holding the car keys in my hand, I suddenly felt like I had been poked hard in my heart.

I thought that for the past seven years, I had been walking alone in the dark, not seeing the slightest light, and not needing light.

Unexpectedly, in addition to Tang Yirou, there were so many people gathered around him. I owe a favor that I may never be able to pay off in my life.

Out of Song Yuan's house, he found that another round of morning sun had risen outside. Under the reflection of the rising sun, Z City seems to have regained new vitality, and the haze accumulated on the eve has been swept away.

I found the Buick car, and after I got in, I found that there was still a pale pink note on the steering wheel of the car.

"When the weather gets cooler, remember to wear more clothes. I didn't step on the brakes very well, don't drive too fast, I wish you to catch the murderer as soon as possible. Signature: Lin Xiaoxue, who stands with you at all times. ”

Glancing at the note, I smiled helplessly, then folded it and stuffed it into my pocket.

Twisted the key, stepped on the accelerator, and drove the car directly to the office building where Lu Yuan was.

After checking the surveillance footage all night, I believe that the guy can give some special discoveries, and now, all the clues seem precious, and there is no sloppiness in the slightest.

Two hours later, I arrived at the office building. When I returned to this place after a few days, it was as if I had overturned the Five Flavors Jar for a while, and there were all kinds of flavors.

Lu Yuan stayed outside the security room early in the morning, eating fried dough sticks and soy milk, while patiently waiting for my arrival. It can be seen that he was also busy enough this night, and his two eyes were swollen like rotten peaches and covered with bloodshots.

"How about it, why don't you get one first? It just blew up at the door. ”

"Don't, I'm afraid of getting angry, you eat quickly, tell me what you found after eating."

Lu Yuan stuffed all the fritters in his hand into his mouth a few times, took out a tissue and wiped his hands, and then walked to the security room with me.

In the huge room, hundreds of surveillance video tapes are stacked with them.

You know, because the surveillance probe is fixed, the scene in each stack of videotapes is exactly the same in most cases.

To watch all these tapes and find something wrong with them is like digging through a bag of fragrant rice to find a few sticky grains, and the point is that until then, you don't know if there is glutinous rice in that bag of fragrant rice.

The night before, God knows how Lu Yuan survived.

"Alright, now you can tell me what you found."

"Hehe, after reading it, I'm sure you'll thank me."

After Lu Yuan finished speaking, he skillfully inserted two stacks of video tapes into the player in front of him, and after a night of torment, I believe that he was already familiar with the operation steps of these instruments.

After a few moments, the screen in front of me gradually became familiar.

"This is the surveillance footage around 2:40 that night, and I searched for a long time to find this."

"What key did you find in the picture?"

"Look carefully, I'll explain to you later!"

Lu Yuan adjusted the main screen to the monitoring screen of the hall on the first floor and the entrance of the twelfth floor, and after a while, a blurry figure appeared near the entrance of the corridor on the twelfth floor, as the picture gradually approached, I gradually saw that the character who appeared in the picture was Chang Qingshan!

"In other words, Chang Qingshan did not go through the main hall, but directly entered the office building from a certain passage?"

"Either he came in through the back door, or he stayed in the office building all the time. Anyway, I checked all the surveillance footage in the hall two days ago, and I didn't see him enter at all! ”

I must believe in Lu Yuan's work efficiency and concentration, if he analyzes it this way, then the former is even more likely.

After all, there is no place to serve food in the office building, and unless he enters with enough food in advance, I don't believe that guy can hide in it without eating or drinking for two days in a row.

The time when Chang Qingshan appeared on the twelfth floor was around 2:40, and the time when Liu Hao and I entered the office building was around 3:15. There was an interval of about half an hour between us and Chang Qingshan.

That guy was clearly deliberately staying in the editorial office waiting for me and Liu Hao, and this time point was a little too punctual.

Is it a coincidence? Or did someone inform Chang Qingshan in advance that Liu Hao and I would be there?

"Look at the picture behind the twelfth floor!" Lu Yuan saw that I was a little stunned, and raised his tone to remind me, which brought my attention back back.

In the picture, Chang Qingshan didn't walk fast, but just as he was about to walk out of the monitoring area, this guy suddenly stopped, then turned his head and looked behind him.

As if he were talking to someone, he argued fiercely and gestured with his limbs, and after a moment, made a gesture of helplessness, turned and walked up the third floor.

But during the whole process, I didn't see the second person other than Chang Qingshan appear in the surveillance screen.

Cold sweat unconsciously flowed down his back, could it be that at that time, there was an invisible guy who was staying in the corridor talking to Chang Qingshan?

Lu Yuan looked at me very calmly, and after a while, he gently spit out this sentence: "It should be a matter of angle, the place where the person who spoke to Chang Qingshan was standing just happened to have perfectly escaped the monitoring probe at the entrance of the building, so it would create the illusion that Chang Qingshan seemed to be arguing with the air." ”

"It's just your inference, can you prove it?"

"I think there should be a way, since the real murderer can do it, then we must be able to do it!"
