A Hangzhou woman died. Three playing cards were found at the scene: 5 of Spades, J of Diamonds, and K of Spades. Let the experts explain.

5 of spades, K of spades, J of diamonds.

Judging from these three cards, they make no sense. There are many guesses. If you look at the fingerprints on the card, you should know whether it is the message left by the deceased. Judging from the creases, it looks very new, which is rare. That leaves what the murderer left behind. It is not uncommon for the murderer to leave behind three playing cards after killing someone in foreign movies and TV series. Why did he do what he did? First, it shows that he has been planning for a long time; second, he has a strong desire to express himself. J K looks out of order, a bit like shorthand for Jack the Ripper. Five of Spades: I don’t know if you have heard a little joke by Fei Yuqing. The Five of Spades represents women. (Perhaps the number of targets he is prepared to take action on). For details, you can look at the deeds of Jack the Ripper, but the murderer was probably a novice, and his methods were not as sophisticated as Jack's. He did not complete the plot, which means that he is about 20-30 years old. He usually has low self-esteem and is not very tall, so the target he chose is a young woman who is not very tall. Let’s analyze it in reverse: If JK killed someone because he was abandoned by his mother, his target would be a middle-aged woman. Then the murderer's goal implicitly explains his motive: revenge on the young woman who once hurt him (but it is impossible to kill her directly, so it seems that he cannot complete his imitation ritual, if this is his first A target, it was just for him to practice. Maybe he didn't know the deceased at all.)

The top priority now is to find the identity of the deceased, and it is not ruled out that he committed the crime outside and moved the body to Yuhang. Now there is an uproar in Yuhang, and no one knows the deceased. Assuming that this is an orphan living alone, her social circle should be very small. There is a tattoo on the tiger's mouth, indicating that the educational experience of the deceased is not high (no insult at all, to be honest, maybe it has something to do with her profession.) Increase the investigation of Zhejiang nightlife, someone should know her.

If it is really imitating JK, then a target should also appear in Yuhang. It’s not more than a month apart, and I should be bolder next time. From a human perspective, I hope to catch him as soon as possible, because he is very proud now. He has created a puzzle in the streets and alleys, and he has finally become a popular figure; from a criminal investigation perspective, I am looking forward to him. The next time he imitates, if he disappears, no one will be able to find him again.
