My neighbor's name is Conan

If a temperature regulator was used in the aquarium, and since Satoshi Nishida happened to drown in a bathtub, the water temperature could be changed to affect the estimated time of death.

Isn't this a perfect match?

After hearing this, Yukisuke Imura went up to take a look and replied, "It's a red long-browed shrimp."

"Where does this shrimp come from?" asked Aoki Matsu.

Although I have never heard of this name, as long as I know where it comes from, I can roughly calculate the water temperature where the shrimp lives, and thus determine whether there is a temperature regulator.

Before Yukisuke Imura could speak, Ai Huihara said, "The red long-browed shrimp comes from the southern coast of the Sea of ​​Okhotsk and the Pacific coast from Hokkaido to Sanriku. It likes to live in sandy mud at a depth of 400 to 600 meters."

Qing Musong raised his eyebrows when he heard this. These places sounded very cold.

Now the red long-necked shrimps are dead, so is it possible that the refrigerator has been misappropriated?

If a body has been in cold water, removing the refrigerator before the body is discovered and allowing the water temperature in the bathtub to return to normal can confuse some officers and cause them to make incorrect estimates of the time of death.

This trick is not uncommon. Aoki Matsu has handled a case like this before and had some connection with a forensic doctor.

"Ah, ah." Yuan Tai suddenly raised his voice and pointed at the aquarium and said in surprise: "There is a very small jellyfish still alive on it."

"Really?" Ayumi looked carefully and finally found the jellyfish. She said happily, "It's a tiny jellyfish."

"Jellyfish?!" Conan was a little surprised when he heard it and looked over carefully.

Qing Musong also looked over, and then his face changed. "This is not a jellyfish, it's a contact lens!"

"Mr. Nishida, are you wearing contact lenses?" Aoki Matsu looked at Imura Yukisuke and asked.

Imura Yukisuke nodded, "The teacher is wearing contact lenses."

Upon hearing this, Aoki Matsu immediately said to Maruta Ayumi in the area, "Maruta, check if the corpse is wearing contact lenses in both eyes."

"Yes!" Maruta replied.

Soon the results came out, and Maruta reported to Aoki Matsu in a low voice: "Inspector, Mr. Nishida is wearing a contact lens in his left eye, but not in his right eye."

At this time, Detective Tomi came over and said, "Inspector, the blood test report is out. The report shows that Mr. Nishida's blood alcohol concentration is 0.4%."

“0.4%!?” Aoki Matsu was shocked.

Maruta Ayumi interrupted, "Normally speaking, in this situation, one is almost unconscious."

Detective Tomi continued, "The fingerprints on the wine glass are consistent with Mr. Nishida's fingerprints."

Qing Musong nodded: "Thank you for your hard work."

"It's all my fault!" Imura Yukisuke said with a look of regret: "I have always advised Mr. Nishida not to drink too much, but in the end..."

At this time, Aoki Matsu's cell phone rang. It was Detective Fukuda who went to the airport to verify the situation of Imura Yukisuke.

"Inspector, I was just at Narita Airport and I found out that Mr. Imura purchased a ticket for a flight that would land at 9:9 this morning. The plane was not delayed and landed at the airport on time at :," Detective Fukuda replied.

"I understand." Aoki Matsu responded.

It takes about 50 minutes to get here from Narita Airport, and about an hour considering the time spent waiting for the bus.

In other words, after Yukisuke Imura landed at 9:, he immediately rushed here, put away the refrigerator, let the water in the bathtub warm up, and then waited for Professor Agasa and the Junior Detective League to come, and pretended to have just returned.

Thinking of this, Aoki Matsu walked to the aquarium where the shrimps had died, opened the lid on it, and then saw the refrigerator inside.

There is a temperature display on the refrigerator, and it is currently 4.3 degrees.

Qing Musong carefully took out the refrigerator, took out a flashlight and shone it on the refrigerator, and found fingerprints on it.

[It should be this machine! ]

However, considering that Yukisuke Imura was Satoshi Nishida's assistant, he could justify the presence of Yukisuke Imura's fingerprints anywhere in Nishida's house, so Aoki Matsu conducted a second test.

Detective Dengmi brought the nitrous acid reagent, and Aoki Matsu carried Imura Yukisuke on his back and sprayed it on the refrigerator.

Didn't Yukisuke Imura say that he practiced shooting in Guam, so his clothes might have been stained with gunpowder. When he rushed back from Guam to perfect his method of committing the crime, Yukisuke Imura might not have been completely calm and collected, and he might not have changed his clothes, and the gunpowder on his clothes might have rubbed against the refrigerator.

With no other evidence, Aoki Matsu had no choice but to give it a try.

I didn't expect that there would be a smoke reaction on the refrigerator.

【Ke Xue, definitely Ke Xue! 】

Aoki Matsu shouted "Ke Xue" in his heart, but he smiled on his face.

Because this is irrefutable evidence!

After getting up, Aoki Matsu looked at Yukisuke Imura and said, "Mr. Imura, I don't think Mr. Nishida drank alcohol before he died."

"Huh!?" Imura Yukisuke was surprised.

Professor Agasa and the little members of the Junior Detective League were also shocked.

Of course this does not include Conan and Haibara Ai, because both of them saw Aoki Matsu's actions and had a guess in their minds about who the murderer was.

"There was a red spot on Mr. Nishida's neck that looked like a mosquito bite. It was a mark of being pierced by a syringe. First, the murderer quietly approached Mr. Nishida who was making a model and used ether or some other drug to make Mr. Nishida fall asleep temporarily.

Then, a syringe was used to inject alcohol directly into the blood vessels in Mr. Nishida's neck. In this way, alcohol would appear in the blood of the body, making everyone mistakenly believe that Mr. Nishida was drunk when he died.

Then, the murderer put Mr. Nishida, who had lost consciousness, into the bathtub and drowned him. "That's what I said, right, Mr. Imura?" Aoki Matsu looked at Imura Yukisuke and asked.

"Huh?!" Imura Yukisuke was shocked when he heard this, but he still had a lucky mentality on his face and pretended to be stupid and said, "Did I do something?"

Aoki Matsu said directly, "You are the murderer of Mr. Nishida."

"How could that be?!" Imura Yukisuke knew he couldn't play dumb after hearing that, so he denied it first, and then argued, "I was in Guam on the Friday night when Mr. Nishida died!"

"No!" Qing Musong looked at him and said, "Mr. Nishida was not killed by you on Friday night. You must have killed Mr. Nishida on Thursday before you left for Guam.

Because the bathroom light at the corpse scene was not on, only during the day when sunlight shone in through the large window, the bathroom was bright, so you forgot to turn on the bathroom light. "

"What are you talking about?" After hearing what Aoki Matsu said, Imura Yukisuke became anxious and his voice became much louder. "Didn't you just say that Mr. Nishida died on Friday night?"

"That's exactly how you committed the crime." Qing Musong said in a firm tone without panic, "Because you refrigerated the body and postponed the time of death."

"Refrigerate the body?" Yuan was shocked.

Although he had seen many cases, big and small, with the Junior Detective Team, he was still shocked by the endless stream of criminal methods.

Aoki Matsu nodded and continued to reason: "The adhesive attached to the fingertips of Mr. Nishida's right hand does not seem to have solidified yet. This is because it is more difficult for the adhesive to solidify at low temperatures. The body was also refrigerated, so the adhesive on the fingers could not solidify quickly."

"Indeed, if the body is refrigerated, the time of death can be postponed." Huibara Ai agreed.

Ayumi asked in confusion: "But how do we keep the body cold?"

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

"Use this thing." Qing Musong pointed to the refrigerator he had just taken out of the aquarium and said, "This aquarium feels very cold because we are going to raise marine life from Hokkaido, so we must keep the aquarium at a very low temperature. Therefore, this aquarium is equipped with a refrigerator that can cool the water temperature.

Mr. Imura used this refrigerator to cool the water in the bathtub, keeping the body at a low temperature, thereby delaying Mr. Nishida's death.

The evidence that he used the refrigerator is that there is a contact lens floating in the aquarium. I have had someone check it out and confirmed that Mr. Nishida was wearing a contact lens in his left eye, but not in his right eye. "

When Aoki Matsu was talking about the refrigerator, Imura Yukisuke could no longer hold it in. The expression on his face was out of control, looking a little ferocious, and his whole body began to tremble.

[You're not mentally competent, brother.] Aoki Matsu looked at Imura Yukisuke, who seemed to be in the state of confessing himself, and complained in his heart.

But Qing Musong continued, "I think the reason why the contact lens fell into the aquarium is this: Mr. Imura came back from Guam this morning and had come here before Dr. Agasa and the others.

Because he had to put the refrigerator used to refrigerate the body back into the original aquarium, but the cooling rod placed in the bathtub had the contact lens taken from Mr. Nishida's eye on it.

Mr. Imura did not notice this. When he put the refrigerator back into the aquarium, the contact lens attached to the cooling rod fell into the aquarium. The reason why all the shrimp in the aquarium died was that the water temperature rose after you took out the refrigerator, and the shrimp had difficulty adapting to the change in water temperature.

Although Imura Yukisuke was shaking unconsciously, he still refused to admit his guilt and said, "I didn't come to this house this morning. I met Dr. Agasa and others at the door when I came."

Upon hearing this, Aoki Matsu said, “I just sent someone to ask Narita Airport. There is only one flight from Guam to Tokyo this morning, and it will arrive in Tokyo on time at 9:.

It takes 50 minutes to get here from Narita Airport by car, and it takes about an hour including waiting for the bus to get off. And Dr. Agasa and his team arrived here at 12 o'clock, so you have a full hour and a half to do these things. "

"This is outrageous! It's just your inference and there is no evidence at all." Imura Yukisuke shouted at Aoki Matsu in his dying struggle.

"We criminals are not detectives. We won't randomly say who the murderer is without evidence." After saying this, Aoki Matsu raised his hand, pressed the bottle of smoke reaction tester in his hand and sprayed it on Imura Yukisuke's body.

The next second, gunpowder smoke appeared on Imura Yukisuke's chest.

Before Imura Yukisuke could get angry, Aoki Matsu gave up the position where he had just been standing, exposed the refrigerator, and sprayed at it again.

"Smoke reaction!" Aoki Matsu looked at Imura Yukisuke and said, "Mr. Imura, you didn't change your clothes after practicing shooting in Guam, so there is still smoke reaction on your body."

Imura Yukisuke was a little confused when he heard this, "Smoke reaction?!"

Aoki Matsu never expected that Imura Yukisuke had planned to kill someone, but he didn't know about the reaction of gunpowder smoke. He explained speechlessly: "After the gun is fired, the gunpowder inside will fly all over the place. So if it comes into contact with liquid containing nitrous acid, the gunpowder stuck on clothes and furniture will react and finally turn into purple-red color."

"Ah!" Yukisuke Imura subconsciously covered his clothes.

However, his clothes had been sprayed with nitrous acid solution by Qing Musong, and one area had turned purple-red.

"Mr. Imura, you went to the shooting range to shoot on Saturday night after leaving Guam, but you didn't change your clothes, so when you put the refrigerator back into the aquarium, the gunpowder on your clothes got on the refrigerator. Do you have anything else to say?" Aoki Matsu looked at Imura Yukisuke and asked.

"Damn it!" Imura Yukisuke cursed, "I did it perfectly."

Perfect?!

Haha, you’re the only one here.

This case is still the easiest proof question.

Perfect ass!

Aoki Matsu was too lazy to be a father, but Aihara Yoji was not as enlightened as Aoki Matsu. Hearing this, he said sarcastically, "You never expected that the alibi you worked so hard to create would become evidence to identify you in the end."

"Why?" Dr. Agasa looked at Imura Yukisuke with some confusion and asked, "Why did you kill Nishida? Didn't you always respect Nishida?"

"Five years ago, that was indeed the case." Imura Yukisuke looked up at Dr. Agasa and said self-deprecatingly, "Because he was a genius aquarium designer at that time. I really, really respected him."

Dr. Agasa was puzzled when he heard this. "It was like that five years ago. What does this mean?"

"Nishida hasn't been able to design anything since five years ago. He has used up all his talents. So, all his works in the past five years were thought up by me," revealed Imura Yukisuke.

"What!" Dr. Agasa was shocked when he heard this. "You designed it?"

[Ah, this... is another copyright case between teachers and students.] Aoki Matsu complained in his mind after hearing this.

"Yes." Imura Yukisuke responded, "I am the shadow warrior behind Nishida. However, even so, I don't care as long as I can do the design I like under the name of a genius. I don't care even if it is unknown. It's because I respect Nishida very much."

Qing Musong was a little surprised when he heard this. If that was the case, then how could a murder happen?

Then I heard Imura Yukisuke angrily say: "But, as soon as Nishida found out there were other talented young people, he wanted to abandon me and use the newcomer he found. I can't forgive him!"

【Ah this...】

This reason was something Aoki Matsu never expected.
