My neighbor's name is Conan

Aoki Song raised his eyebrows and asked quickly: "Are you taking her to the station gate, or are you watching her get on the tram?"

The two are sometimes said by some careless people to be "delivered to the station", but celebrities are completely different.

"They were sent to the station, and we separated at the ticket gate." Kurata Seiji said.

Aoki Song raised his eyebrows, "So, did you see her get on the tram?"

The three of them looked at each other, then shook their heads.

Shizuka Kawai, the representative of the three people, said: "No, after we waved goodbye to her, we turned around and left. We don't know when she got on the train."

Is it true that he doesn’t know, or is the murderer deliberately lying?

Aoki Song continued to ask calmly: "How did the victim look at that time?"

"I couldn't see anything wrong with her at that time." Shizuka Kawai replied.

"Did the three of you leave the station directly after breaking up with the victim? Or did someone leave in the middle, such as going to the toilet." Aoki Song asked again.

These words made the three of them realize that Aoki Song was suspecting them to be the murderers, and the expressions on their faces became a little strange.

Shizuka Kawai's tone started to sound a little harsh, "No, the three of us walked together. No one left during the journey. After eating, we returned to the company together."

"Yes, after we returned to the company, we also worked in a large office, and no one left during the process." Kurata Seiji also said.

Yukiko Mori nodded, "Yes, after we separated from Kiyomi, the three of us have always stayed together and have never been separated."

Seeing that something was wrong in the atmosphere, Mouri Kogoro started to make jokes with a sharp look, "The time you and Miss Kiyomi should be separated is before 6:30."

"We didn't pay attention to the time at the time. We weren't sure what the exact time was, but it should have been less than 6:6. After the three of us returned to the company, I took a look at the time. It was only [-]:[-] at that time." Yukiko Mori replied.

"So, do you know if the victim has ever had a dispute with anyone?" Aoki Song asked.

"No!" All three of them shook their heads.

At this time, Mouri Kogoro looked at Kurata Seiji and said: "Mr. Kurata, according to what you just said, you have been rejected by Miss Kiyomi, so you should be the most..."

Before Mouri Kogoro could finish speaking, Kurata Seiji, who already knew what he was going to say, quickly retorted: "Don't be ridiculous, besides me, Yukiko, you also hate her because her boyfriend was robbed by her. Is she right?”

Yukiko Mori was stunned when she heard this, and then quickly retorted: "I never said that!"

After hearing Yukiko Mori's retort, Seiji Kurata ignored her, looked at Shizuka Kawai and said, "And Shizuka, didn't you also say that Kiyomi stole your design?"

"What on earth do you want to say!" Shizuka Kawai had a bad temper. When Seiji Kurata brought the matter to her head, she immediately said in a bad tone.

[It’s begun, it’s begun, and it’s time to explode again. 】

[Uncle Maori, good job! 】

Aoki Song gave Mouri Kogoro a thumbs up in his heart. As for the fact that after the three people exploded, they all had the motive to attack the victim, he was not surprised at all. It is a classic three-choice case, so naturally everyone must be interested in it. There is suspicion!

However, Mouri Kogoro was a little dumbfounded, "So, you three have a motive?"

"How could we kill Kiyomi?" Shizuka Kawai said excitedly.

Kurata Seiji and Mori Yukiko were also very excited to defend themselves after hearing this.

"Okay, stop arguing." Aoki Song said with a cold face: "In daily life, some conflicts are normal. Detective Maori, you don't need to be so suspicious."

Aokimatsu looked at Maruta Ayumi and asked, "Has the site been inspected?"

"We have investigated everything and found nothing." Maruta Ayumi replied.

Aoki Song glanced at him, motioned him to step aside, and then gave him a few instructions in a low voice.

The carriage where the body was found had indeed been inspected, but... Yukiko Mori had excused herself before and went to the carriage next to her, but there was no inspection.

If the murderer was Yukiko Mori, he would definitely take the opportunity to throw away the physical evidence.

Judging from the current situation, although there is no evidence, according to the laws of science, Yukiko Mori is the most likely murderer, so it is necessary to be cautious.

After giving orders to Maruda Ayumi, Aokimatsu walked over to three more people and said: "But you three are indeed suspected, so please let the police check the items you carry with you. This will also help to clean up your possessions." I am suspected of this, please cooperate with me."

"Okay, you can check as you like. Anyway, I didn't kill Kiyomi." Shizuka Kawai was the first to speak, looking confident.

With Shizuka Kawai as No. 1, the other two people also said it was okay.

Then the three of them took out the things they carried and placed them on the floor of the carriage.

Because there is a high probability that these three people are the murderers, and the murder weapon has not been found yet.

Instead, something was missing, which was the thing that was pressed between the victim's left upper arm and the carriage wall, causing marks on the corpse's left upper arm.

Therefore, Aoki Song personally started the inspection, and the first one to inspect was Yukiko Mori, who was the most suspected.

After careful inspection, Aoki Song soon discovered that Mori Yukiko's earphones were broken.

Picking up the earphones and looking at them, Aokisong suddenly discovered that the wire thickness of the wired earphones was the same as the thickness of the indentation on the left upper arm of the corpse.

so……

He did not draw a conclusion immediately, but quickly scanned the other two people's things. There was nothing similar to strips inside.

Aoki Song narrowed his eyes, Yukiko Mori's suspicion became even greater.

Assuming that Yukiko Mori was the murderer, the earphones should have been worn on the victim's head at that time, and the earphones should have been worn for a long time, otherwise the earphone wires would not have left indentations that would not disappear for a long time.

In this case, Aoki Song guessed that the victim should have been wearing headphones when he died, and he had been sitting on the ring line with headphones on.

Later, Yukiko Mori and two others got off work after finishing their work and boarded the tram.

Then, without the other two people paying attention, Yukiko Mori moved the body, took off the headphones on the victim's head, and stuffed them into her bag.

Why do you want to do this?

Is there any risk in doing this?

What is her purpose?

Aoki Song quickly reasoned in his mind.

The victim is already dead, so what is the difference between a body found with headphones on and a body found without headphones?

For some cases, there is no difference, but for this case, the difference is huge.

After thinking about how the victim died, Aoki Song had the answer in his mind.

The victim died because a poisonous needle-like object pierced the auricle.

To be honest, this position is really difficult to stab when the victim is awake.

Firstly, the area is small and difficult to pierce, and secondly, the auricle is a relatively sensitive part, and people can feel it if a needle-like object pierces it.

If Aoki Song is asked to do this, since the poison on the needles is fatal, then the neck and heart must be chosen!The difficulty dropped a lot instantly.

In addition, the victim was still wearing these large over-ear headphones, so under normal circumstances it would be impossible to penetrate them.Of course, it is also possible that the other party put the earphones on the victim's head after he succeeded.

In other words, Yukiko Mori wanted to create a situation where the victim was stabbed with a needle while sitting on the tram, rather than dying while the victim was listening to music with over-ear headphones.

Yukiko Mori wanted people to ignore the earphones, so she removed them after the victim died.

Maybe she was a little nervous at the time, worried about being discovered, or maybe the body was stiff and difficult to remove, so Yukiko Mori pulled the earphones and broke them when she took them out.

So how could the victim be stabbed with a needle-like object and die when he was wearing over-ear headphones?

Aoki Song guessed that there was a high chance that this headset had a mechanism!After the victim puts it on, the needle hidden inside will prick out.

So he quickly checked the headset carefully and found that the spongy body inside the left ear of the headset was gone.

It seemed that the other party had hidden a poisonous needle in the corpus cavernosum. After the victim put on the headphones, he was stabbed to death immediately and the poisonous needle was later withdrawn.

But there is still a problem - how to avoid risks?

Yukiko Mori arrived at the station with the other two people and got on the bus together. If everyone was together, how did she avoid the sight of the other two people and take off her earphones?

Are the other two accomplices?

It's possible, but everyday cases shouldn't be that bad.

Aoki Song felt that there should be details that he hadn't noticed or didn't know yet.

Just as Aokimatsu was thinking, Maruta Ayumi walked in with excitement, quickly approached Aokimatsu, and then whispered in his ear: "Police department, according to your instructions, we searched the car next door. In a seat A very small needle was found underneath.”

Aoki Song nodded to show that he understood.

The murder weapon has been found. It seems that the previous hypothesis is correct and Yukiko Mori is the murderer.

But the evidence?

And the question just now, how did she avoid the sight of the other two people and remove the earphones from the body?

Aoki Song thought for a while and came up with an idea. Except for a few of these daily cases where the modus operandi was quite fancy, other cases tested the details.

For example, there were details about whether the three of them separated when they got into the car.

However, Aoki Song did not question the three of them immediately. Instead, he checked everyone's belongings first.

Sure enough, there is still something to gain.

On one of the magnetic disks, there is a piece of paper with a red gel pen written on it: Thank you Yukiko, Shimizu, 99.8.22.

Seeing the time, Aoki Song subconsciously raised his hand and glanced at his watch.

Well, the time is right, today is the day.

and many more……

Aoki Song remembered that he picked up a gel pen under the victim's seat, which was also red, so to speak...

The victim was probably stabbed to death by a poisonous needle before he could take the pen back after writing this, so the pen fell under the seat. Therefore - Yukiko Mori probably didn't know that the victim had written this on this magnetic disk. A matter of words.

evidence!

Here is the proof!

Aoki Song's eyes lit up.

However, the case cannot be closed even though the evidence has been found. There is still an unresolved issue ahead.

Aoki Song looked at the three of them and said, "Three of you, I will question you separately. After the questioning, if you agree with each other and there is no suspicion, you can leave."

The first half of the sentence made the three of them quite unhappy.But after hearing the second half of the sentence, the expressions of the three people softened a lot.Thinking that they could go back, the three of them expressed their cooperation.

The first person Aoki Song asked was not Yukiko Mori, who was the most suspected, but Seiji Kurata, the big-mouthed man who had revealed the revelation before.

"Excuse me, from when you got off work around 7:[-] to when you got on the tram and found the victim murdered, were the three of you always together?" Aoki Song asked.

Kurata Seiji immediately replied after hearing this: "The three of us walked to the station together after work, but when we were about to get on the train, Yukiko said she was going to buy juice, and the juice vending machine was across from us. I stood at the ticket gate waiting for the tram, two carriages away.
