The two stayed until their colleague arrived.

When they returned to the serious crime team, Zhou Li and Li Hua had not returned, only He Xingchen and Chen Hui were there.

"Boss, Officer Su, I heard that you went to ask Wang Jian!" As soon as he saw the two of them, Chen Hui came over, "What happened to the result?" ”

Just now, he and He Xingchen explained to those residents in the villa area that they were really big.

As a result, though, they also have some gains.

"Nothing came of it." Su Tong shook his head and replied for Xu Sa, "Wang Jian won't say anything." ”

"So hard-mouthed?" Chen Hui touched his chin, "However, we have found a little bit here." ”

Xu Sa pulled a chair aside and sat down, his legs on the table, "What did you find?" ”

"When we were communicating with the resident next door to Wang Jian, we heard from the other party that just half an hour before we arrived, the other party saw a figure leaving Wang Jian's house."

"Figures?" Xu Sa and Su Tong's faces changed at the same time, and Xu Sa sat up straight, "Did the other party say who it was?" Man or woman, how tall? ”

"Boss, you're underestimating me, aren't you?" Chen Hui rubbed the tip of his nose, "I will still ask these basic questions." ”

"It's just that the results weren't very good. The other party said that because it was too dark at that time, and he saw it from the second floor of his villa, the distance was too far away, and he couldn't see it clearly, and he couldn't judge the men and women, let alone the tall, short, fat and thin, anyway, it was a black figure. ”

Xu Sa, isn't "......" the same as not saying it?

"However, we also got an important clue from the words of our neighbors." Chen Hui raised a finger and said, "That's right, the other party said that after the man left Wang Jian's villa, he left on foot." ”

"So, I asked Senior Brother Xiao He to call up the surveillance video of the villa area, and I'm watching it now!"

"That's good, Chen Hui, there is progress!" Xu Sa gave Chen Hui a thumbs up, "I can think of this, excellent!" ”

Chen Hui scratched his head embarrassedly, "It's not that you usually teach well, Junior Brother Xiao He and I just asked a few more words." "I didn't expect to be asked by them for clues.

Xu Sa regained his spirits, "Okay, now we will investigate in two lines, one is the surveillance video of the villa area, and the other is the DNA extracted from Wang Jian by the people from the trace examination department." ”

That's right, in Wang Jian's villa before, he and the people from the trace examination department talked about this matter.

Because he noticed that Wang Jian's body had a few traces of fighting, he suspected that Wang Jian's body might be stained with the other party's skin tissue or something.

Then the people from the trace examination department went to Wang Jian's place.

Now, they're just waiting for an answer from the trace department.

"Team Xu ......" He Xingchen, who was staring at the phone on the side, turned back bitterly, "I'm afraid this monitoring is useless......"

"What's going on?" Su Tong walked over quickly, this ups and downs are too big.

I just said that there was a clue, but it's only been a long time, and the clue is gone.

"The property management in this villa area cut corners, and there were a total of 24 cameras in the entire community, and only 12 were turned on." He Xingchen pointed to his screen.

And I saw that half of the little cells were black.

"According to eyewitnesses, the revelation of the suspect from Wang Jian is this. And the property just didn't have a camera with this line on......"

He only found out after reading it all.

Xu Sa, "......"

Chen Hui, "......"

"......" Su Tong thought for a while and said, "What about outside?" "Now that the time of the suspect's departure has been determined, can they investigate the people who entered and exited the community during that time?

If there is no monitoring in the community, there is always a road control outside the community!

"Yes, yes." He Xingchen nodded honestly, crackled twice on the computer keyboard, and several other interfaces appeared, this time from the angle, these pictures were taken from outside the villa community in the direction of the villa, but it was not very clear.

"Officer Su, look, because of the angle of these cameras, they couldn't directly shoot the door of the community. If you investigate, you can only measure and compare the whereabouts of each person who appears in the picture, and only after comparing it that it may have come out of the villa can you continue the investigation......"

In short, it's a huge amount of work, and he needs time.

Xu Sa's face turned black now.

Su Tong patted He Xingchen on the shoulder, "It's okay, you always have to give it a try." Just do your best, we still have time. ”

He Xingchen nodded movingly, turned around and threw himself into the video investigation again.

Chen Hui also went to help He Xingchen, although he didn't see as fast as He Xingchen, but one more person always had an extra pair of eyes.

"It's all my fault, since we guessed that Wang Jian might have a situation tonight, we should have gone early." Su Tong sighed.

It was she who was too confident, confident that she already knew everything, otherwise, they would probably have brought back the person who attacked Wang Jian and Wang Jian by now.

"What a stupid thing!" Xu Sa stretched out his hand and rubbed her head, and said dotingly, "I am your captain, and I will always be the one who makes the decision, have you forgotten?" ”

"But ......" Knowing that Xu Sa was comforting himself, Su Tong frowned, and wanted to say something.

Xu Sa shook his head and interrupted her, "No, but, according to what you said, let's go earlier." In case our appearance happens to be seen by the person who injured Wang Jian, the other party may hide for a while. ”

"So, it's not a bad thing to be like this now." At least, they knew about the existence of another important person in the case.

The four of them sat in the office for a long time, and in the middle of the night, Zhou Li and Li Hua finally came back, and they still had an inspection report in their hands.

"Boss! The brothers from the trace examination department extracted a part of the skin tissue from Wang Jian's nails. According to the inspection, those skin blocks did not belong to Wang Jian! Zhou Li said excitedly.

In Wang Jian's nails, it doesn't belong to Wang Jian, it must belong to the murderer!

"Have you found out the identity of the other party?" Xu Sa quickly took the report and opened it, and saw that there was a conclusion written in it.

"I haven't had time to check it yet." Li Hua replied, "We are in a hurry to come back and tell you the news and Officer Su!" ”

"Captain Xu, I've opened the information relationship system on the case!" He Xingchen's voice came from there, "You can make a comparison at any time!" ”

"Good!" Xu Sa asked He Xingchen to log in to his mailbox and took out the electronic template sent by the trace examination department from it for comparison.

The most important thing is that the other party's DNA is in this system, and they can find out the person!
