Reason: 1. B woman, clothes are not conducive to action. Who will have the mind to dress up after killing? Clothes will be stained with blood when killing. And B's shoes are high heels, which are not suitable for running.
This man didn't participate in the murder, but he must know something. If we take the suitcase as a case, I personally think that if the murderer is busy running away after killing, how can he empty the suitcase? It must have been arranged by the man or in advance, so both sides are suspected. However, if a married woman suddenly loses something or takes something out, it will definitely arouse her husband's suspicion, so the best way is to trick her husband into going out to play or something, so it is very simple to pack up her luggage in advance. Of course, those things you mentioned may be newly bought, but this possibility is relatively small. After all, the cost of a person fleeing is quite high, and there is no spare money.
3. Let's talk about flowers again. You can't be so idle when you escape. Generally, only couples who come to play, the woman thinks it looks good, and the man buys it. If we pretend to be sweet, but they are already lovers, why bother? Besides, what does it matter whether it is sweet or not? Anyone can see that, even if there is, it can only be said that the relationship between husband and wife is not harmonious.
4. Personally, have you found that all the women's boxes in A are on the ground? Generally speaking, hotels don't put boxes on the ground, because they are going to the guest room soon, and then even if they are on the ground, they should hold the handles. Then why just let them go? It is very likely that she hurt her hand when she killed her husband. If the box is also brought by man A, then the one above is not valid, but there is still a problem. Since they are all carried by the man, why not put them in the suitcase? Let's assume that if woman A is a neat freak, the above is not true, but why does she grab her left arm with her right hand for no reason? This action is very strange. If she is used to it, it can be vaguely seen from the picture that she is holding the bag. Why does she care so much about the bag? It may be the money she fled, or it may be some evidence. But according to the length of the right hand, it is absolutely impossible to reach the suitcase at that angle and position.
Personally, the hotel owner knows the real murderer only by seeing a flaw. I don't know where the flaw is, but I also found some strange places. The woman's standing posture is too formal and she feels a little nervous. Plus the movement of her hand, you can try it. It's weird. In addition, male A is very serious. At first glance, he is either a rich man or a face-saving man, but the woman's dress is too ordinary. Imagine that if it is the above two possible men, he will dress his woman like this, then that suit is just for the convenience and relaxation of escape.
The above is a personal guess!
