It is very likely that she has ignored something, it is very likely that she has ignored a certain detail, and sometimes a detail can change a lot of things.

She had thought before that with the intelligence of the person behind her, it would be very likely that the person who helped him bring things was a suitable reason, and that the person who helped him bring things felt that it was a very normal thing.

If this is the case, there would be no strangeness in the expression of the person who brought his things.

"good."

Tang Ling did not ask more or say anything more. Instead, he adjusted the video again according to Wen Ruoqing's intention.

Wen Ruoqing still stared at the scene without blinking and continued to observe, but this time Wen Ruoqing was not only observing the patient's expression, but this time she paid attention to all the details.

Tang Ling helped her adjust the video and skipped the time when the middle patient entered Yuan Yu's office, and only the scenes of the patients entering and leaving Yuan Yu's office.

Tang Ling has watched it several times, so he is very skilled in adjusting the video.

"Stop."

Wen Ruoqing shouted quickly when she saw a patient walking out of Yuan Yu's office.

The moment Wen Ruoqing was shouting to stop, Tang Ling stopped the surveillance screen.

"What's wrong?

Is there any problem?

This person looks normal.”

Tang Ling looked at the person on the screen carefully and found nothing unusual.

"He didn't hold a cell phone in his hand, but when he went in, he held a cell phone in his hand."

Wen Ruoqing was not paying attention to the person's expression. That expression was indeed very natural and there was nothing unusual.

"Yeah?"

Tang Ling was stunned for a moment, and then quickly adjusted the video back again. Sure enough, when he saw the patient entering, he was holding a cell phone in his left hand.

"Will he put it in his pocket? He is wearing a coat. It's normal for him to be like him, and he is not the only one. Why do you think he has a problem?"

It was not that Tang Ling did not believe in Wen Ruoqing, but was objectively analyzing some things.

Tang Ling turned out the picture of the patient walking out of Yuan Yu's office again: "The left corner of his clothes is slightly lower from the right, so his phone is likely to be put in his pocket."

Wen Ruoqing did not explain, but instead turned out a picture of the patient walking towards Yuan Yu's office. In the video, the person's body was facing them, but he could still clearly see the corner of his coat.

"When he went in, the corner of his clothes on the left was slightly lower than the right, the same as when he came out of Yuan Yu's office. So, if his cell phone was in his pocket, then when he went in, his cell phone was already in his pocket. When he came out, nothing was added to his top pocket. If he put the cell phone in his pants pocket when he came out, it would be more obvious, but from the surveillance, it was obviously not, so the cell phone in his hand was left in Yuan Yu's office."

Tang Ling looked carefully, analyzed it, and then narrowed his eyes slightly: "Qingqing, you are right. The phone he was holding was indeed not taken out."

"This is the fragment of the mobile phone we just found in Yuan Yu's office. I'll see if it's made of the same material as the mobile phone that the person was holding."

Ye Sichen took out the fragments of his phone and placed them in front of the surveillance camera.

"It's impossible to see it like this. Moreover, the person held the phone in his hand at that time. The phone was not big, and there was almost nothing in his hand. We couldn't even see the phone's appearance. How could we tell what material it was?"

Tang Ling glanced at the cell phone fragment, then looked at the cell phone held by the patient on the surveillance camera, and he felt that it was impossible.

"The material should be the same, but you can find another professional trace analyst to confirm it."

Wen Ruoqing came to the conclusion directly, and she had a positive tone.

"Qingqing, can you tell it?

How did you see this?"

Tang Ling was shocked. Although he had always known that his Qingqing was very powerful, he did not expect that his Qingqing was so powerful that he could only see the material of the mobile phone from the surveillance monitor that could not tell the appearance of the mobile phone at all.

"Qingqing, you are really amazing. I admire you more and more."

"Check the surveillance in other places in the hospital to see who the patient has had contact with other places in the hospital. The person asked the patient to help bring a cell phone to Yuan Yu, but the patient did not have any suspicion. He must have had contact with the patient and would definitely have a conversation."

Wen Ruoqing turned her eyes and looked at Tang Ling. Tang Ling's tone was a little exaggerated. Now that she has this clue, let's follow the clue to look up.

"Okay, I'll check it right away."

Tang Ling had long invited other people in the surveillance room. Now there are only three of them in the surveillance room, so it is very convenient to check.

This time, Tang Ling just found a video of the patient who was given a mobile phone. Tang Ling did not let go of the video of the patient as long as there was a video of the patient.

Through the surveillance video, they found that the patient took the cell phone out of his pocket after going to the third floor.

"Look, when he went upstairs, the man had already given him his cell phone."

Tang Ling paused when the patient took out the screen of his phone: "Check the previous video and you will find it."

At this moment, Tang Ling's voice became a little more excited. He had searched for so long and had no results, but now he finally found out.

Tang Ling continued to watch the video, from the patient entering the hospital, from the patient's registration, and then the patient went upstairs to Yuan Yu's office, Tang Ling checked without missing a glance, but found nothing.

After the patient entered the hospital, he had never contacted other people except when registering, nor had he spoken to others.

"It seems that the man didn't give him his cell phone in the hospital. He is so cunning and cautious."

Tang Ling found nothing after finding out, and his face became a little heavier.

"Finish this person first."

Wen Ruoqing narrowed her eyes slightly. Since she had not found the person who gave the patient a cell phone, then she would find the patient first.

At that time, you can at least ask about some situations.

"I asked Gu Wu to look for him. Gu Wu is best at this. He must find that person as fast as possible. There must be no accidents again."
