"This is the left hand of the female deceased, whose ring finger was cut off by a knife." Xu Yancheng said, "In addition, her right hand also broke several fingers. ”

"Did you find the severed finger?" He Zheng asked.

Xu Yancheng took the mouse, clicked a few times, flipped back a few pictures, and then said, "Here." ”

He Zheng's dark eyes flashed, and his fingertips pointed to a certain place in the picture: "There is a circle of traces here." ”

Xie Xiaojia and Xu Yancheng looked carefully, and near the bloody wound, there was really a circle of marks.

It's just that the wound is too shocking, and the marks are very faint, so it's hard to detect if you don't look extremely closely.

Xie Xiaojia gasped and glanced at He Zheng in disbelief.

You must know that He Zheng's gaze never stays on each photo for more than a second.

It was in such a short period of time that he was able to notice this detail?

What an amazing power of observation and attention!

"This is a long-term strangulation of the ring, the ring finger of the left hand...... What should be worn here is a wedding ring. He Zheng muttered, "So, what about the ring?" ”

"Rings?" Xie Xiaojia was stunned, "We didn't find any rings at the scene." ”

She suddenly reacted and said in surprise: "Could it be that the ring was taken away by the murderer?" The murderer is a thief, so he kills for money?! ”

Because their suspicions were focused on Peng Wei before, they did not consider the aspect of seeking money and killing people.

"No, not a thief in the truest sense of the word." He Zheng shook his head.

Then with a flick of the mouse, the on-site investigation report was opened.

He pointed to a few of the pictures.

"The site environment is very neat, nothing out of the ordinary. If it's a thief or something, it's just going to be a mess because you're rummaging through your belongings. And you also said that the door lock has not been damaged by external forces, and it is still a combination lock, and it will not be a thief in the ordinary sense. ”

Xu Yancheng stroked his forehead and sighed in frustration, "Who is the murderer?" The more you talk about me, the more confused I become, and I think I'm still better at dealing with corpses. ”

"There's no hurry." He Zheng hooked the corners of his lips slightly, "Although the elevator has monitoring, I can guarantee that there should be no monitoring in the corridor where the deceased's house is located." ”

Xie Xiaojia nodded: "That's true, there is no monitoring installed in the corridor, only the elevator." ”

"What about the backup of the elevator surveillance video?" He Zheng said lightly.

"Here." Xie Xiaojia found a video file.

He Zheng clicked on it and chose to fast-forward it at 16 times.

He crossed his hands, leaned back in his chair a little lazily, his dark eyes hidden under his eyelashes quietly watching the rapidly changing picture.

On the screen, people in the elevator are coming in and out.

After a while, Peng Wei and Xu Wanwan appeared, they should be going home, they were still arguing in the elevator, both of them had gloomy faces and seemed very unhappy.

After a while, Peng Wei left alone, and after another moment, Peng Wei came back again......

Later, Peng Wei did not appear.

But He Zheng didn't stop, but continued to watch.

After a few moments, he didn't know what he saw, straightened up, dragged the progress bar back with the mouse, looked at it a few more times, and dragged it back......

Repeatedly, the slender white fingers touched the mouse.

There is a click, and the picture pauses.

Above is a woman in a white dress with long curly brown hair, white high heels, sunglasses, and a black messenger bag.

After Peng Wei went back for the second time, about half an hour later, when the police were about to arrive, she entered the elevator from the 14th floor and left.
