"Cuphu Lucas is the murderer. Kurosawa Silver was the first to turn and walk into the amusement center, "He used this method to create an alibi for himself, in fact, the young man who was dragging died before they played. ”

"Then how did he kill that gentleman?" because he didn't know or remember the name of Julius Caesar, Xiaolan kept calling him by that gentleman. This kind of name has a special meaning for Kurosawa Silver and Gray Plains who live in the organization, but Kurosawa Silver doesn't mind Xiaolan saying this at all. He listened very well.

"It's different from ordinary people's way of thinking about judging cases. If the murderer is identified from the beginning, he thinks about how the murderer will commit the crime from the murderer's standpoint. Kurosawa stopped, he was now in a relatively remote position, but he could clearly see where Julius Caesar had been.

The position is empty, but people can imagine it, just as a murderer fantasizes about where the deceased is, and how he should assassinate him when he actually acts.

"A person will use the usual habits of the person he wants to kill to kill. After Kurosawa said this, he paused, and he looked sideways at Xiaolan, as if waiting for her response.

"That gentleman has a habit of sitting in one position. Xiaolan was trembling by Kurosawa, but quickly reacted, knowing that Kurosawa Silver was preparing to guide her to solve the case, hesitated for a moment, and quickly said the answer.

"Officer Twilight and the others will see on surveillance that Lucas had spoken to the deceased before the game. He was standing on the right hand side of the deceased, with his back to the monitor, and it looked as if he was talking to the deceased. After that they start the game. ”

"If it was poisoned, it was probably at that time. Xiaolan still hesitated for a moment, but the speed of answering the question was a little faster than just now. Her mind drifted a little, and at this point she was rarely distracted to wonder why Kurosawa Silver knew what Twilight and the others could see in the surveillance.

"The autopsy report revealed that tetrodotoxin (1) was found in the deceased's body, and that there were traces of syringe injection on the inside of his right upper arm, and that a stab had pierced the deceased's artery. ”

"Tetrodotoxin?" Xiaolan didn't answer at this time, and instinctively froze when she heard this term.

"It is one of the most toxic neurotoxins found in nature, more than 1,250 times more toxic than cyanide, and 0.5mg can kill people. Kurosawa smiled slightly, "Japanese people seem to like to eat fugu very much, right?" The implication was to ask Xiaolan why she didn't even know about this toxin.

"But my dad said that the symptoms of poisoning in the mouth were slow to progress, and that he could be rescued by taking him to the hospital in time, but the gentleman became ill very quickly......

"Vascular injection of nerves paralyzes and kills faster. ”

Ash Yuan's words made Xiao Lan stunned for a moment, she glanced at Ash Yuan in surprise, and then looked at Kurosawa: "So the murderer used a syringe to kill people?"

"Yes. If we were the police, then after knowing this, we could go and directly investigate the way to obtain tetrodotoxin and syringes, and the clues that the murderer has some medical knowledge, but unfortunately, we are not. Kurosawa's words seem to be a mockery of some people who can't make the most of it.

Xiaolan thought she couldn't hear it, so she continued to listen quietly.

She had expected Kurosawa to continue, but Kurosawa looked at her and seemed to wait for her to say.

“...... Syringe was used, and then?" The silence was painful even if it was short, and Xiaolan couldn't help but ask.

"At this time, you should think about how he brought the syringe in, and how he destroyed the murder weapon. Kurosawa reminded.

Xiaolan smiled awkwardly, she was not very good at thinking about the details of the case, of course, if it was the details of the fight...... Because I'm good at it, I'm more observant.

"Kudo likes to have fun in reasoning, you are his childhood sweetheart, you can try to do it. Kurosawa raised an eyebrow, "Of course, I'm not saying that couples have to be like-minded, but it's not bad to experience it once in a while, isn't it?"

Kurosawa's name came out of Kurosawa's mouth, and Ran sounded a little weird, but she was quickly attracted by Kurosawa's words.

She nodded again.

"Think about what I said at the beginning. ”

It has been said that people will use habit to kill people, so naturally there will be people who use habit to hide that they have killed people.

Of course, these people will naturally show something different from usual in the process of committing crimes, but since Kurosawa Silver specifically mentioned "habits" here, it should be "habits" that need to be paid attention to.

What did the killer do that seemed normal?

Xiaolan thought that the murderer seemed to have a habit of smoking, and her eyes suddenly lit up: "By the way, if you hide the poison needle in the cigarette and bring it in, and then throw the cigarette into the trash can as if nothing happened......"

"That way, the police can easily lock down the killer through the fingerprints on the cigarettes. You're also overlooking a little bit of detail. Seeing that Xiaolan's face showed a confused expression again, Kurosawa Silver turned his head, and his eyes fell on the group of people who had just finished watching the surveillance video, "No, it should be missing a little fragment that can piece together the truth." ”

"What?"

"Listen to the voice. ”

The deliberate guidance made Xiaolan subconsciously focus on her ears.

Ugh. Ugh. Ugh.

Xiaolan's pupils gradually widened, and finally locked on the waiter's body.

There was a slight grinding sound as the man walked, much like the sound of a key shaking, but it was clear that the waiter was not wearing these things, and the source of the sound was the soles of his feet...... There seemed to be a piece of paper under his feet.

Cigarettes, paper ...... Something missing......

Xiaolan's shoulder was suddenly patted, and she turned her head to Shangyuanzi's face: "Xiaolan, what do you say to Brother Kurosawa?" I have already accompanied the monitoring to watch, and the first thing who approached that man was the waiter who was kicked...... Then there was the guy named Shimizu Takabao who talked to him with his back to the monitor...... By the way, this person walked to the screen and bent down, saying that he was picking up a lighter...... Later, a policeman came in and said that the cause of death was tetrodotoxin, and I was shocked by the professionalism of Mr. Judy when explaining the toxin......"

Kurosawa Silver lowered his head and grinded with Gray Yuan's ears and temples: "The name of that murderer has two words that are the same as yours, just in time." ”

...... "Gray Plains, "Your focus is really different from others. ”

It's not the same.

Xiaolan's first thought was that Kurosawa had grasped the information that the police were about to get in advance, and then his attention was focused on the seemingly casual complaint in the garden: "Having said that, the quality of the people here is really not high, and there are still people throwing chewing gum around!" I saw that when the waiter bent down to tie his shoes, there was tin foil under his shoes, and it was estimated that the chewing gum in his mouth was tasteless when he was playing a game, and he threw it directly on the ground with a pack of tin foil from the cigarette case...... Heh, should I say that he didn't just spit the gum on the ground and pollute the floor, is it still a little hygienic?"

The garden expressed great disdain for this immoral behavior.

Xiaolan's eyes lit up again.

"Garden!You're really a great help!" Xiaolan excitedly reached out and held Yuanzi's hand, the fierce action startled Yuanzi, and before Yuanzi could react, Xiaolan let go of her hand and looked at Kurosawa, "-He hid the poison needle in the cigarette afterwards, and then used chewing gum to stick the cigarette to the tin foil, and put the tin foil on the ground under the pretext of picking up a lighter, once the game starts, everyone will gather in front of the screen, and naturally someone will step on the evidence and take it away!"

"Congratulations on discovering the key to chewing gum. Kurosawa curled the corners of his lips, "Once the cigarette is flattened by the test pressure, it will not feel like stepping on it." Even if someone notices it, they will think that it is just a cigarette butt thrown by a customer because of the cigarette roll on the surface, and they will easily throw it into the trash. ”

"But that needle may pierce passers-by through the sole of the shoe and poison people......" Xiaolan's face showed an embarrassed expression.

"Do you think someone who is going to kill would care?" asked Kurosawa with a smile.

Xiaolan fell silent, and her face became sad again.

And Yuanzi, who didn't figure out the situation just now, finally came back to her senses, her eyes widened, and her gaze wandered on Kurosawa and Xiaolan: "Are you teaching Xiaolan to reason? And you already know the murderer, are you pushing back his modus operandi?"
