crime scene

Only one of the public offices in the huge city bureau was lit.

Yang Wenxuan made a bowl of instant noodles for him and put it on the table, but Chu Duanyu took it away and ate it first.

"When did you see our captain let Su Nian eat this?"

Yang Wenxuan thought about it, he went out to buy supper reluctantly, Chu Duanyu thought about it, after all, he was also a junior, so he went with him.

Zhang Yitian and Su Nian sat in front of the computer together, and they watched the live video twice, totaling more than three hours.

It was almost twelve o'clock in the middle of the night, Zhang Yitian stretched his waist and drank some tea.

"Do you want coffee?" Zhang Yitian asked him.

Su Nian nodded.

No tampering was found in the on-site video, and it may be because of the angle that some tampering was not captured.

So Su Nian drank his coffee and watched videos from other angles, but still found nothing.

Chu Duanyu fell asleep on the table after eating supper.

"Su Nian, what's the use of watching this live video?" Yang Wenxuan leaned over and asked.

Su Nian didn't know how to answer, so she simply turned off the video and turned on the surveillance video.

Su Nian watched a dozen or so video files all night. As mentioned in the previous report, there was only Qian Qian in the suspicious time range.

Su Nian tried his best to engrave every second of the picture in his mind, and when he saw it for the fourth time, Su Nian finally discovered the problem.

"Brother Tian, ​​wake up!"

With Su Nian's shout, Yang Wenxuan, who had fallen asleep, was also called out, and Chu Duanyu jumped up from the table, looking around in confusion.

"What did you find?" Zhang Yitian asked with a sigh of relief, "06:30, you watched it all night..."

"Brilliance Business Hotel is a five-star hotel, and the house numbers are all electronic. Watch these few videos. Although the house number is too far away to see clearly, but after zooming in..." Su Nian said, fingers on the keyboard Operate quickly.

Zhang Yitian felt ashamed of himself when he saw how fast he started.

"The house number is reversed. In this case, the room Xiqian entered at the beginning was not 0412 at all."

"I'll do a technical appraisal." Zhang Yitian immediately turned to the computer and started working.

"Su Nian, let's go to the hotel again, one day, contact us at any time." Chu Duanyu said, trimmed his hair, grabbed the wrists of Yang Wenxuan and Su Nian with each hand, and took them out.

Only Chu Duanyu had a good rest that night, so he drove, and Yang Wenxuan went to buy two pancakes to eat on the way.

When I visited the Brilliance Business Hotel again, the director's face was still so ugly, anyone who wasn't blind could see the distaste in his eyes, but no one cared.

"Who was on duty that night?" Su Nian asked.

The supervisor pointed to the schedule on the wall, turned and walked away.

Yang Wenxuan was very puzzled, so he leaned over to look, "This Ma Xueheng... haven't we made notes?"

Chu Duanyu put his arm around Yang Wenxuan's shoulder, and explained, "He must have other questions."

Ten minutes later, Ma Xueheng appeared in front of 10, disheveled and disheveled. She was on the night shift and was still a little confused.

"On the night of the incident, you were at the front desk all the time, and you didn't go anywhere?"

Su Nian asked Chu Duanyu a little surprised, it was just the most common question.

Ma Xueheng shook his head firmly.

So Su Nian asked again, but she still shook her head.

After staring at the girl for another minute, Su Nian motioned for her to leave. The girl complained in a low voice inexplicably, then turned around and pressed the elevator button.

Not only the girl, but Chu Duanyu also felt baffled. Just as she was about to ask, she saw him walking straight to the other side of the corridor, so she exchanged glances with Yang Wenxuan and quickly followed.

"Wait, I didn't realize it. In the surveillance video, the master turned left, but the surveillance was flipped left and right. In fact, the master should have gotten off the elevator and turned right...but room 0412 is on the left..."

Yang Wenxuan followed along while chattering, but almost missed Chu Duanyu in front of him.

"what happened?"

"I didn't bring my mobile phone, so I called Brother Tian'er. I want the hotel's plan and the floor plan of the fourth floor." Su Nian said.

Yang Wenxuan quickly took out his phone and called Zhang Yitian.

"Hey brother, Su Nian wants the hotel plan, especially the fourth floor."

"Send it to you right away, and Panpan and I made the technical analysis results. The surveillance was flipped and cropped, and a lot of blank videos were spliced ​​together in post-production, except for the guests who stayed. There was definitely more than that on the night of the incident. The captain is alone on the fourth floor."

Su Nian raised her hand, signaling Yang Wenxuan to give him the phone, and Yang Wenxuan did as he did.

Su Nian said, "Brother Tian'er, check to see if there are any signs of intrusion in the hotel's electronic system that night, and whether there are any bugs in the electronic key card, and whether you can make a universal electronic key."

"Let me see, it may take a little longer. If it can be done, it will take at least three or four hours."

"it is good."

Within half a minute of putting down the phone, Zhang Tiantian sent the pictures Su Nian needed.

There are a total of 32 rooms on the fourth floor, 0412 is on the left, but if the sect number is reversed, then Xiqian entered the wrong room at the beginning.

Instead of 0412 from left to right, it is 0421 from right to left.

Su Nian lowered her head, walked to the door of room 0421, opened her mouth, and said calmly, "This is it."

He believes that his judgment will not be wrong.

"I'll contact the front desk, Brother Chu, please prepare first."

Chu Duanyu ignored him, knelt down and took out gloves and shoe covers from the inspection box, handed a set to Su Nian after wearing them, then took out the inspection light, and searched for the doorknob.

Very clean, no fingerprints or palm prints.

After waiting for a while, Yang Wenxuan came back with the key card, and opened the room in a hurry.

"I asked, let alone this room, this floor is sealed, no one lives in it, and no one cleans it."

The furnishings in the room are exactly the same as those in 0412.

The first thing Su Nian did when he entered the house was to look for the ring, but was stopped by Chu Duanyu.

If no one cleaned this room, there should be some evidence left. He turned on the light and searched for it bit by bit, so Su Nian had to wait outside with Yang Wenxuan.

"Yes... It's the shattered glass of the red wine bottle. It's very small. If this is the first scene, it should be left by the murderer!"

Chu Duanyu's excited body trembled a little, and she almost couldn't hold the tweezers steadily.

Su Nian followed Chu Duanyu, carefully looking for the ring.

The fact that he didn't find what he asked for first on a whim at that time became the most critical physical evidence.

Chu Duanyu and Yang Wenxuan also bent down to search carefully.

Suddenly, a shiny object behind the door caught Su Nian's gaze.

The ring was lying there. If it were a person, it would probably be in peace with the world.

Su Nian hurried over to put the ring away. The surface of the ring was very clean, without dust or scratches, but the size was exactly Su Nian's.

Putting on the ring, Su Nian breathed a sigh of relief.

"This is the real crime scene!"
