The suitcase involved in the case is a key point, this is obvious, and everyone here knows it.

But none of them were able to draw out a line like Qi Yuan to connect the key points of this case, and there was no big logical problem.

But it is also difficult to find clues and try to open a breakthrough in the investigation, and how Li Rui's suitcase was replaced is a big problem.

After all, from the case to the present, for three days, they have not given up solving the mystery of the suitcase, but they have not gained anything so far.

This breakthrough is not easy to break through.

"Smack!"

Brother Song raised his head, lit a cigarette, and continued to ponder.

The others didn't have the heart to eat, so they pushed their bowls and lit cigarettes to think.

"Li Rui and Qin Haoyu, the two suspects, obviously don't know about this matter, and the possibility of their replacement can be ruled out." Fang Chang suddenly spoke, breaking the silence: "The possibility of accidentally 'taking the wrong one' does not exist.

We watched the monitoring several times, and no one entered and exited the elevator with a similar style of suitcase, and Li Rui's so-called putting the suitcase at the door to throw away garbage and buy water was just a temporary thought, and the monitoring showed that he did not pick up garbage when he went out, and he did not take water in his hand when he went to send the express.

Moreover, if it was accidentally 'taken by mistake', his suitcase would not have been present at the scene.

Obviously, there is definitely another insider in this case who has not shown up so far, and he replaced the two suitcases under the noses of Li Rui and Qin Haoyu, but the motive is unknown and the method is unknown......"

At this point, he sighed again, shook his head and said, "Forget it, these are obvious things, when I didn't say it." ”

"Replacing a suitcase shouldn't be a prank - no one has the guts to do such a prank at the murder scene, there must be another purpose." Lao Hai took over: "That...... Whether he knew that Li Rui was also involved in this case, one of the purposes was obviously to drag him into the water, and we might be able to investigate in this direction. ”

"And surveillance." Qi Yuan immediately said, but then he was deflated and shook his head: "I'm sorry, I forgot that there is only an elevator in that building, and there is no corridor or unit door, as long as this person is cautious enough not to take the elevator, he can't find anything." ”

"There's another direction." Brother Song seemed to have finally cleared his mind, flicked the ashes, and said, "How did this guy know." After completely taking down Qin Haoyu, you have to ask who knows about the conflict between him and Zhu Weibing.

Determine the scope of the investigation first, and then the rest will be relatively easy. As long as this insider can be found, perhaps, he can ask about the way Li Rui participated in this case.

No matter how bad it is, there is such an insider, who wants to break Li Rui's psychological defense, or simply affect his judgment, so that he realizes that confession is more beneficial than stubborn resistance to the end, and the case will be broken. ”

"There's one more problem." Qi Yuan thought for a while and asked, "Is this goal an insider or a participant?" If it was just an insider, why didn't he call the police?

And if it's a participant...... Where is another participant? Zhu Weibing's family has offended so many people?

And, it's not necessary, right? If Qin Haoyu only wants to kill Zhu Weibing, and this will is not so firm, and Li Rui wants to destroy their family, it is understandable to push a hand in the back.

But what about this participant? Since Li Rui is involved, everyone in this family has been wiped out, why does he still wade into troubled waters? Could it be that this person's hatred for this family is so great that he is unwilling to push it?

In addition, why did he bring Li Rui back into this whirlpool? It's hard to understand.

Of course, as long as this person can be found, these mysteries should be solved, but if the mystery can be solved in advance, it may ...... The identity of this person is about to be revealed? ”

"The possibility of simply 'knowing' and not participating should not be high, otherwise, as you said, he can directly choose to call the police, and there is no need to make such trouble. Of course, it is not ruled out that he is worried about being retaliated against by Li Rui, but there is no need to consider it for the time being. Brother Song answered:

"So simply from the point of view that he was also involved...... What you just said is also reasonable, there is an inexplicable contradiction here, unless I tell you that the contradiction between him and Zhu Weibing is so big that he is unwilling to participate in it and set up a situation in it, even if he takes a little risk for it. ”

After a pause, he shook his head again: "But this possibility is not very likely, if there is such a big hatred or contradiction, it should be difficult to suppress, and when we visited and investigated before, we should be able to find some clues."

So...... There may be another possibility - he is more Li Rui is a cooperative relationship, jointly promoting the plan behind the scenes, and pit Li Rui at the last moment. ”

"Huh?" Fang Chang's hand trembled, and a piece of cigarette ash fell into the bowl.

He hurriedly picked out the cigarette ash with a small piece of rice, and then said: "Then this person is interesting, he has a grudge against Zhu Weibing's family, wants to destroy his family of three, and has a contradiction with Qin Haoyu - of course, it may not be a contradiction, but it is indeed a murder with his hand, which greatly increases his guilt."

That's not all, there was a contradiction with Li Rui, and the cooperation was good, but he pushed him at the last moment and killed him...... Tsk, such a complicated interpersonal relationship should be easy to check. ”

Qi Yuan opened his mouth and closed it again, wanting to speak and stopping.

This action was captured by Brother Song, so he asked, "What's wrong Xiao Qi, do you have an idea?" It's okay, speak up. ”

"I'm thinking...... There may be a person who satisfies the above contradiction very coincidentally. ”

"Huh? Who? Brother Song was a little stunned, but then he had an idea, and asked uncertainly: "Yes...... Qin Qingqing? ”

"Yes." Qi Yuan nodded and said, "She has a conflict with Zhu Weibing, this is obvious, after all, they are about to change from enemies to lovers."

was once beaten by Xu Yun, which is also a contradiction, she may not have completely let go, and she may still hold a grudge. What's more, she had a falling out with Zhu Weibing, to some extent, it was actually related to Xu Yun - although Xu Yun was actually very aggrieved here - she might not be angry with Xu Yun.

Besides, by now, we can actually be sure that Qin Haoyu is not a sister control as he showed himself, on the contrary, he may not have much brother-sister affection for Qin Qingqing at all, but has been using her.

Qin Qingqing is a smart person, maybe he can also find out the fucking things that Qin Haoyu did, it is normal to feel uncomfortable, and it is understandable that he even resents because of this.

As for Li Rui...... I think the reason why he participated in this case is probably inseparable from Qin Qingqing, after all, his girlfriend, or even his fiancée, has been messing around with other men for two years during her relationship with her, and she must have a fire in her heart. ”
