And Yan Yu on the side, his expression rarely eased.

This Duan Bing called him Mr. Shinian?

It was a pleasure to hear.

I hope they solve the case well, and if they encounter difficulties, he doesn't mind helping them in the back.

Duan Bing raised his eyebrows when he heard Shi Nian's words, and his face became serious: "In addition to the fall injury, Ms. Song Xiaoyu also has scratches of varying degrees on her body, and there are also red marks on her face, and she seems to have been slapped hard before she died. ”

Song Shinian took a sharp breath.

In the room next to her, there should have been four people that night, two men and two women, except for Song Xiaoyu, a soft and weak girl, the other three were not good.

Not to mention the two big men, Kong Wu is powerful, let's just say that the one named Yanyan also looks like a domineering woman who is not easy to mess with.

Song Xiaoyu is traveling and has no acquaintances here, except for these three 'roommates'.

Her personality is not the type that is easy to get revenge, so excluding suicide, if it is concluded that he killed her, it must be between her three 'roommates'.

But who will it be?

Song Shinian hurriedly looked at Duan Bing, his eyes were urgent: "If he killed, then is the suspect between her roommates?" Then you can focus on her boyfriend and another woman. ”

Shao Bing raised his eyebrows: "Huh? How do you know? What did she say to you in the elevator? ”

Song Shinian took a deep breath and said, "Since you have seen the surveillance video, you must have also understood the relationship between her boyfriend and that woman." ”

This Duan Bing was even more surprised, "What is their relationship?" ”

Song Shinian looked back at the other party in astonishment, speechless for a while.

The intern next to Duan Bing couldn't hold his breath, looked at Shi Nian and couldn't help but ask, "What is their relationship?" Why do you say you'll know if you watch the surveillance footage? But we looked at the surveillance and didn't find anything. ”

The corners of Song Shinian's eyes jumped, and he turned his eyebrows to look at the young man, "Since you don't know their relationship, who do you suspect?" ”

"Lin Senbei."

The intern blurted out, but was glared at viciously by Duan Bing.

According to the current evidence, this murder was killed by him, and he didn't run away, so he is not afraid to make it public; But the suspects they have targeted are not yet suitable for publicity.

It's just a small action between them, and Song Shinian didn't pay attention to it at all.

She looked at the two people opposite her with a serious face, and said solemnly, "I don't know why you suspect Lin Sen, but I can tell you why I suspect the other two. Because yesterday I happened to take an elevator with the four of them, and I stood behind them and happened to see Song Xiaoyu's boyfriend secretly holding hands with the woman named Yanyan. ”

"They each split their boyfriend and girlfriend."

After Song Shinian finished speaking, he saw that the intern's mouth had opened into an O-shape in shock, and the big ones could be stuffed with eggs.

She looked at her for a moment, "You didn't see such important information when you looked at the surveillance?" ”

The intern blinked and stopped talking.

Even Duan Bing coughed lightly, his eyes wandering to the table.

Yan Yu next to him is rarely a person.

He attached it to Shi Nian's ear and whispered: "It may be a blind spot for monitoring." ”

Song Shinian's eyes widened and he looked at the man suspiciously.

I heard the other party continue to analyze: "You see that the monitoring of the elevator is installed in the upper left corner of the door, but the two people holding hands are secretly held behind their backs, and the movements are not big, and they may not be able to capture such small movements when they are blocked by the body." ”

Song Shinian paused: ...... Makes sense.
