The fat man happily walked to Fang Tianyu's side, and put a hand on his shoulder, "Tianyu, I breathed a sigh of relief for you, should you praise me twice?"

Fang Tianyu pushed away the fat man's hand and looked at him sharply, "I call you Fat Master, if you are full, we will start working." ”

Although he didn't want to admit it on the surface, the fat man did help everyone out of a bad breath, not to mention how cool it was in his heart.

It's not that he's afraid of Ma Jing, it's just that he hasn't been willing to see him in general, and out of respect for a veteran policeman, he hasn't said anything.

The fat man stuck out his tongue at the keyboard and shrugged his shoulders, "Everyone starts working, and in a moment Tianyu should say that we are not doing our job." ”

Everyone took some surveillance video from the mall, and everyone is investigating the surveillance video tonight, hoping to find some clues. Fang Tianyu glanced at the brothers who were working hard, he was very pleased, although he usually sometimes laughed and laughed, and he was very serious about completing every task at critical times.

As the minutes passed, everyone's eyes kept staring at the computer, and their eyes were bloodshot, but no one stood up to say that they were tired. Fang Tianyu looked at it from the side, "If you are tired, take a rest, you can't stand staring at the computer for a long time, and it won't be bad for a few minutes." ”

Jin Yuan stood up suddenly, "I'll go out to buy drinks for everyone, you guys can take a break at this time." ”

Fang Tianyu stopped Jin Yuan, who was about to go out, "Jin Yuan, you stay, I'll go out to buy it, and I'll be back soon." ”

Jin Yuan nodded, she really didn't want to walk, she did eye exercises to relieve visual fatigue. She then casually took a video record from her side and continued to work, she kept looking at the people on the elevator, and suddenly found that there was a back figure that was very familiar.

Continuing to look behind the familiar back, Jin Yuan was slowly fast-forwarding, until in the time of forty minutes later, she clearly saw Bai Guilan's face. She immediately pressed the pause button, she got up and looked at Fang Tianyu's card position, the person happened to come from the door behind her, she stammered nervously, "Captain, come ...... Look, white ...... Guilan!"

As soon as Jin Yuan's words fell, everyone immediately stood up and came to her side to watch the video on the computer, and sure enough, it was Bai Guilan. Fang Tianyu moved the mouse and found that Bai Guilan appeared next to the elevator of the international shopping mall, and there was an old acquaintance by her side-Zhang Lele.

Everyone was curious about why Zhang Lele also appeared in the international shopping mall, is this a coincidence? Or is it intentional? With doubts, everyone continued to look down, and sure enough, they saw Zhang Lele arguing with Bai Guilan, and finally the two of them actually fought, and Bai Guilan rolled down the elevator without standing firmly.

The video shows everything clearly, and as for why they quarreled, I don't know at all, because there is no sound in the surveillance video. Now everyone is relieved, everyone's hard work has finally not been in vain, at least they know how Bai Guilan's head injury came about.

Early the next morning, everyone from the second team appeared in the police office as scheduled, waiting for Fang Tianyu to give an order. The fat man and the keyboard went to follow Zhang Lele, and he and Jin Yuan went to the international shopping mall to find the witnesses at that time, at least to know why Bai Guilan and Zhang Lele quarreled.

The fat man questioned directly, "We can bring Zhang Lele to ask, is there any need to go out and follow him?"

Fang Tianyu's face was gloomy, "It's not terrible to be lazy, it's terrible to have no brains, don't forget, Bai Guilan's death was poisoned." ”

The keyboard hurriedly relieved the fat man, he pulled the fat man and walked towards the door, "You have too much nonsense, the captain must have his reason for arranging this." ”

Fang Tianyu and Jin Yuan were also about to go out, and at this time, Du Bo spoke, "Master, do I still stay to watch the house?"

Jin Yuan comforted Du Bo, "Doctor, don't underestimate the mission you stay, in fact, it is the most important thing, the captain trusts you." ”

There are a lot of people in the international shopping mall every day, looking at the crowd of people coming and going, Fang Tianyu didn't know where to start asking for a while, he asked tentatively, "Jin Yuan, you are a woman, do you guess why Bai Guilan and Zhang Lele quarreled." ”

Jin Yuan pondered for a while and said: "The intersection between them is nothing more than Wang Dazhuang, and it must have something to do with this man." ”

Fang Tianyu nodded, "Let's go separately and inquire about these stores at the elevator entrance first, there should be witnesses who may know what the reason for their quarrel is." ”

He made inquiries from the east side of the elevator exit, while Jin Yuan started from the west, and the two of them were temporarily separated. Jin Yuan first asked a store of branded shoes, but found nothing, and also asked about the store of brand-name bags, but still no one noticed that Bai Guilan rolled off the elevator that day.

She had already asked several companies for this meeting, and everyone said that they hadn't noticed, and the hope that had finally been ignited seemed to have suddenly extinguished. She couldn't help but make a phone call to Fang Tianyu and asked him if there was any news on his side, but the result was the same, and he didn't know about it.

Fang Tianyu encouraged Jin Yuan not to be discouraged, maybe there would be hope in the next second, in short, he must find the person who was present at the time. Jin Yuan hung up the phone.

In front of her was a women's clothing store, and she walked in slowly. The shopping guide politely asked Jin Yuan, "Hello, do you buy clothes for yourself?"

Jin Yuan went straight to the point and said, "Police, did any of you see someone rolling off the elevator two days ago?"

The shopping guide looked at Jin Yuan in surprise, turned around and looked at the colleagues around him, "Lina, you come here." ”

Jin Yuan's gaze shifted to another shopping guide, and the voice of the shopping guide next to her sounded in her ears, "It's Lina who is wearing a ponytail over there, I heard her say two days ago that someone fell from the elevator." ”

Lina walked over at this time and glanced at Jin Yuan in front of her suspiciously, "Sister Wang, did you tell me something?"

Sister Wang introduced Jin Yuan to Lina, and then left with acquaintance, leaving Lina and Jin Yuan standing together in a daze.

Jin Yuan went straight to the point and asked, what did Lina see at that time, and she had to tell herself everything she knew. Lina already knew that Jin Yuan was a policeman, and she didn't dare to say more, but just described what she knew that day.

Lina was returning from the bathroom and noticed that someone was arguing in front of her, so she stepped forward to see what was going on.

Lina got closer and saw that it was two women arguing, and she thought it was just some misunderstanding that caused friction, but later she heard it more clearly and realized that it was not the same thing.
