Seeing that Yin Bing seemed to have a clue, Lao Yu immediately asked, "Xiao Yin, what did you find?"

"I haven't found any doubts yet...... Wait! Look, there's a problem!"

Yin Bing rewound part of the video, pointed to the less than in the video and said to Lao Yu: "Look at the little one, you still have the watch you gave him at this time!"

In the video, Xiao Xiao is wearing a suit, taking out his room card and opening the door, and he can clearly see that he is wearing a watch on his wrist.

Lao Yu nodded again and again, and said, "Yes, yes, it's this watch, it was originally mine, and I asked him to wear it before I came here." ”

Yin Bing fast-forwarded for a while, and then Zhang Quan knocked on the door to enter the smaller room, and he could see that Zhang Quan's wrist was empty and he was not wearing anything.

However, when Zhang Quan returned to his room from the small room, he kept hanging his arms, only when he entered his door, his arms were slightly bent, Yin Bing fixed the picture here, and kept zooming in, and gradually you could see the image of a circle of watches exposed at his cuffs. At this time, he wore a watch on his wrist!

Lao Yu exclaimed in a low voice, "This! This is my son's watch!"

Yin Bing asked, "Uncle Yu, are you sure it's this one?"

"Do you see this blue? It's the sapphire on his buckle, I'm too familiar with this watch, it's right!"

Yin Bing continued to play the video, and when Xiao Xiao, who was wearing casual clothes, walked out, Yin Bing zoomed in on the screen again, and looked at it carefully frame by frame.

In the moment when he was less than a hand, he could clearly see that he was wearing the sapphire-encrusted watch on his wrist. Yin Bing froze the picture here, and Lao Yu was stunned when he saw it, "Why is there still a watch?"

Yin Bing asked Lao Yu to carefully identify whether this watch was the one he gave to his son.

Lao Yu couldn't wait to get into the computer at this time, he put his face on the screen, looked at it carefully for a long time, and then said with some uncertainty: "It should be this watch, you look at this position, although it is not very clear, but you can see that it has a blur, I think this is the scratch mark I rubbed." But how can Zhang Quan have an identical watch?"

Yin Bing didn't answer Lao Yu's words, he stood aside and touched his chin and pondered something, and suddenly he said to Lao Yu: "I have to go to the room where your son lived and have a look!"

Yin Bing picked up the landline in the room and called the front desk, asking if room 2013 was empty now, he wanted to change rooms, and the reply was that there was a guest in that room, and the guest was booked to check out three days later.

Yin Bing put down the phone, grabbed his coat, walked out, turned back to Lao Yu and said, "Uncle Yu, I'll go downstairs and have a look!"

Now Lao Yu can't keep up with Yin Bing's train of thought at all, but in terms of action, he plans to follow Yin Bing, he also put on a coat and follows Yin Bing out.

Yin Bing really didn't go far, he stood behind the building, looked at the window on the second floor, and seemed to say to himself: "Sure enough!"

At this time, Lao Yu finally couldn't help but ask: "Xiao Yin, don't play dumb riddles, uncle, you're in a hurry!"

Yin Bing pointed to a window on the second floor, "Uncle Yu, have you seen it, that 2013 room must be the one with a drainage pipe on the side." ”

"How do you know?"

"I've almost guessed what Zhang Quan did, he's been planning it for a long time! Let's go back, I'll tell you everything!"

Lao Yu followed Yin Bing back to Yin Bing's room, Yin Bing didn't sell it, and said straight to the point: "It's Zhang Quan's doing!"

"Oh, then how did he do it?"

"The last person who came out of Brother Xiao's room was not Brother Xiaoxiao, it was Zhang Quan!"

"What? How is this possible?"

Yin Bing sneered: "Uncle Yu, do you think that Zhang Quan is fat, but the person who came out of Brother Xiao's room is very thin, about the same size as Brother Xiao, right?

He had always disguised himself as a fat man, he deliberately wore very thick clothes, or added something to his clothes, in short, he looked like he had a big belly, he was a fat man.

But look at his face,......"

Saying that, Yin Bing adjusted the video to a close-up of the whole face, "You see, his face is not fat, it is normal, and there is even a jawline, this is impossible to be a big fat man."

I guess what happened was like this: the two of them lived in a room arranged by Zhang Quan in advance, and Zhang Quan told Brother Xiao that he would go to him for a while before entering the door to talk about meeting customers tomorrow, and Brother Xiao nodded and agreed.

Ten minutes later, Zhang Quan knocked on the door and entered Brother Xiao's room. In the room, he may have killed Brother Xiao with poison, rope strangulation, or other methods, but there was no bloodshed, which is why the police found nothing in the room.

After finishing the case, Zhang Quan opened the window and put the body of Brother Xiaoxiao on a black bag, slid it downstairs down the drain pipe, and fell into the small bushes on the first floor. It was night, and it was so secluded that no one could see it. And Zhang Quan returned to his room as if nothing happened.

After entering his room, he quickly took off his disguise and changed into his original figure. Then he opened his window, stepped on the buckle of the drain pipe from the window to enter the open window in 2013, at this time he calmly destroyed all the suspicious traces in the room, and then put on a baseball cap disguised as Brother Xiao, went out from the main entrance of the hotel, and took a taxi to leave.

And he should soon get out of the taxi and sneak back to dispose of the body. He did everything perfectly, but he shouldn't have been greedy for money and robbed of his brother's watch, which betrayed him. ”

Lao Yu's lips trembled again, he himself thought that it was one thing for his son to die, and after reasoning about his son's death, and the details were very detailed, as if the two of them had witnessed the crime again, Lao Yu still couldn't bear it.

He finally burst into tears, wiping his eyes with his hands, "What should I do?

Yin Bing coaxed his girlfriend very well, but he was still a little helpless to comfort the old man who had lost his beloved son, and in the end he had no choice but to stand aside and accompany the old man to hand the old man a tissue, so that the old man could vent the sadness that had been accumulated in his heart for many years.

Of course, when the old man was crying, Yin Bing's mind was not idle, he contacted Lingtong again and asked Lingtong if he could find out what cars passed by at the door of the hotel on the night of the crime five years ago.

Lingtong rejected him this time, "You can't take me as a stupid boy to walk! There are more cars passing by at this gate, but this is not the point, the point is that the window of 2013 is behind the building, Zhang Quan will definitely not go through the front gate to deal with the corpse, is it useful for you to let me check the car passing by the door?"

Lingtong probably felt that talking like this was not enough to express his anger, so he directly condensed the image in Yin Bing's mind, pointed at Yin Bing's nose and scolded: "Didn't you analyze clearly and logically just now? Why did your mind get yellow when you came to me? Do you just want to sneak around me, and don't want me to take those four points too easily?"

"Okay, okay, don't argue, I may have just used up all my IQ, and now the balance is a little insufficient, are you scolding me like that! He can't get into the car from the front door, then you can check the car on the back wall, do you still need me to talk about this? Won't you draw inferences? Do you have to let me manually operate and give you instructions? Besides, didn't we say that it's good to be three or seven? Why are you four or six again?!"

There were too many slots at one time, and Yin Bing didn't know which one to complain about.

"There's no surveillance there's on the back wall!" said Spirit Pupil with a snort.

Yin Bing was a little disappointed, and the clue was actually broken again. He couldn't help but touch his chin again, and when Lingtong saw it, he immediately began to shout again: "Hey, you actually imitate me, have you been secretly worshipping me?"

Yin Bing laughed angrily, he put down his hand, paced a few steps, and unconsciously put his hand on his chin again, "Lingtong, what kind of transportation do you say Zhang Quan will use, and how to deal with this corpse?"
