Miwako flipped through the manual and found the record: “Well, according to the forensic examination, the left arm of the deceased was cut off after death, and the reason is not clear…”

“What about the events after that?”

“On the 3rd of this month, we received a report from the Kawashima family of the second chome of Oshima Town that their daughter Kawashima Kana had disappeared for no reason. We were afraid that it was a continuous crime, investigating and monitoring but finding nothing. Until the night of the 5th, I received a report that the body of a child had been found in a nearby public toilet, also bleeding heavily and having his left arm cut off. And in this case, the prisoner did not extort a ransom and directly killed the hostages…” Miwako Sato replied with an ugly look.

Xu Yang nodded: “Did you find anything at the scene?” ”

“The appraiser said that according to the amount of bleeding at the scene, it was just a simple corpse throwing scene, and no suspicious clues were found nearby, but the wound that cut off the little girl’s arm was very smooth, as if it was…”

“Professional cutters, huh? Is there a connection between the two victims of the crime? ”

“Yes, the medical examiner also said that the connection between the victims has not been found for the time being, and it is very likely that the murder is aimed at a specific group of victims…” Miwako Sato’s hand grasping the manual was shaking slightly.

The Twilight Police Department had been silent, if it weren’t for the fact that there were no clues until now, he would not have come to seek Xu Yang’s help on behalf of the above. Watching one young life pass away suddenly, the heart of the police department is extremely painful, the prisoner is not caught, then it is unexpected that there are other people who may be harmed, and even more families may be broken….

Ming Mei was silent, she supported Xu Yang’s decision.

Xu Yang knows his own details, his previous case can only be inferred because he knows the plot, but this case, he does have ideas.

“Why do you think the murderer cut off the left arm of the deceased?”

Miwako Sato and Twilight looked at each other and shook their heads.

Akemi thought for a while and replied, “Could it be that you want to hide something?” ”

Xu Yang scratched Mingmei’s little Qiong’s nose in admiration: “It should be, I think the murderer may be trying to hide his criminal motives.” However, there is no concrete evidence yet, and only hypothetical analysis. ”

“The average little girl’s left hand won’t have anything, so why would the murderer do this?”

In the gap between the three of them thinking, Xu Yang silently thought in his heart: System lottery!

【Drip! Congratulations to the dormitory for obtaining the advanced ability psychological portrait].

[Psychological portrait: from the behavioral psychology genius in “Psychological Crime” – Fang Mu, who can skillfully use psychological knowledge to psychologically profile criminal acts. – Skynet is restored without omission].

A burst of intricate but well-structured knowledge came into Xu Yang’s mind.

Sure enough, it was the same as my own guess…

Seeing that the three still did not make a sound, Xu Yang replied: “In your opinion, this may be a serial kidnapping case.” After all, in the first case, the prisoner demanded a ransom, but in fact, the prisoner planned to kill the victim in the first place. ”

“Really? How so? The Twilight Police Department was very confused, and Miwako Sato had a little clue in her heart, but she was not sure.

Xu Yang continued to ask: “You think, kidnapping and homicide are completely different natures, and if you are caught, the punishment of the latter is definitely much more severe than the former. Why kill the little girl after the kidnappers get the ransom? ”

“Could it be that the victim saw the murderer’s face?” Miwako Sato replied with some uncertainty.

“This is a hypothesis, but in the second case, there was not even blackmail, indicating that the prisoner’s motive was not for money, or even the alleged victim himself.” If the second body also lost too much blood, I think the motive of the prisoner may be the blood itself. ”

“Imagine if the prisoner was for the victim’s blood, then why cut off the victim’s left arm after she died?”

“I know!” Akemi thought of what Xiao Moi, a scientist, would also do, and replied: “If the prisoner’s goal is for blood, the arm was cut off to cover up the traces of blood drawn by needles.” At the same time, in order to mislead the police, it was after the arm was cut off, the victim lost too much blood and died. ”

“Although Brother Xu said so, we only got the motive for the crime, and we can’t determine the prisoner…” After nodding, although this was a relatively big breakthrough, it was much better than the previous dazedness.

“No, why do prisoners have a soft spot for blood? I’m guessing there may be porphyria ..” Xu Yang guessed.

Seeing that the three were confused, Xu Yang continued to explain: “Porphyria is a biological process in which the human body synthesizes heme (simply put, iron + porphyrin = heme), and certain enzyme abnormalities cause the synthesis process to be blocked, so that porphyrins (a macromolecular compound) that are not converted into heme accumulate in large quantities in the body, causing cell damage. One of the manifestations of porphyria patients is that they may have an attachment to blood. It also causes neurological symptoms, which are also the prototype of vampire legends. ”

“Brother Xu means that the prisoner is most likely a patient with porphyria?” Although the police department did not understand a series of scientific explanations, it knew about vampires.

Xu Yang pondered for a moment, scattered information combined in his mind, and said: “The prisoner is a male, aged 28-35 years old, thin in stature, wearing glasses, about 172-178 centimeters tall, and his family is poor. Childhood life may not be very good, and there are currently no family members. If you retrieve the hospital records, it should be easy to find this person. ”

“Thank you Brother Xu this time!” The Twilight Police Department thanked him deeply, and immediately took out his mobile phone and began to give instructions.

Mingmei gently touched Xu Yang’s cheek a little, tender as water.

On the other side, Conan rides a skateboard along the route given by the tracking glasses, and frantically chases a car with Genta and Mitsuhiko.

Hey, hey, hey… Three people a skateboard, the number of people overloaded!!!!

“The banknotes scattered around Ayumi, the scattered heads and their conversations. It is revealed that the two of them are the murderers of the recent serial kidnapping of beautiful girls. Conan speculated affirmatively.

“That Bumei, isn’t it very dangerous, let’s hurry up and save her!”

Genta and Mitsuhiko said indignantly.

“In other words, what about Xiao Moi?” Mitsuhiko suddenly thought.

“…”

“…”

Yonehana Town, Yonehana Park.

“Ahhh… Uh-huh”

Haibara mourned at Hache, his eyes full of boredom, and was hiding at the top of the slide in the park waiting: “Why hasn’t anyone found me yet… Motota couldn’t find it, could it be that Kudo Shinichi’s reasoning had also deteriorated… ”

(PS: I originally wanted to write another case, but as soon as I thought about it, Xiao Mo appeared, and it seems that there is no chance if this case is not written anymore…) Although it was brushed off in the original).
