The woman in Hangzhou is dead. There are three playing cards at the scene: 5 of spades, J of diamonds and K of spades. Come and explain to the master.

Judging from these three cards, it doesn't make any sense. There is a lot of speculation. Look at the fingerprints on the card and you should know if it is the information left by the deceased. Look at the crease, a brand-new degree, rare. This is what the killer left behind. The murderer left three playing cards after killing, which is quite common in foreign movies and TV series. Why did he do it? First, it shows that he has been planning for a long time; Second, he has a strong desire for expression. J K is out of order, a bit like the abbreviation of Jack the Ripper. Spades 5: I wonder if you have heard a little joke by Yu-Ching Fei. Five of spades stands for woman. Maybe it's the number of targets he wants to kill. You can go and see Jack the Ripper's deeds, but the murderer should be a novice, not as sophisticated as Jack. He didn't finish the plot, indicating that his age is around 20-30, and he should be very inferior and not very tall, so he chose a young woman who is not tall. Let's analyze it backwards: if J K kills someone because he was abandoned by his mother, then the target is a middle-aged woman. Then the killer's goal virtually shows his motive: to retaliate against the young woman who once hurt him (but it is impossible to kill her directly, so it seems that he can't complete his imitation ceremony. If this is his first goal, it's just to practice his hands. Maybe he didn't even know the victim. )

The urgent task now is to find the identity of the deceased, not to rule out committing crimes in other places and moving the body to Yuhang. Now Yuhang is in full swing, and no one knows the dead. Suppose this is an orphan, living alone, and her social circle should be small. There are tattoos in the jaws of death, indicating that the deceased's education is not high (not insulting at all, to be honest, it may be related to her occupation. ) Intensify the investigation of Zhejiang nightlife, and someone should know her.

If it is really imitating JK, then the target should also appear in Yuhang. The interval is no more than one month, so be bold next time. From the point of view of human nature, I hope to catch him as soon as possible, because he is very proud now, and the streets and alleys are riddles made by him, and he has finally made a splash; From the point of view of criminal investigation, I am looking forward to his next imitation. If he disappears, no one will find him again.
