My neighbor's name is Conan

Hearing what Maori Kogoro said, Maori Ran said apologetically: "I'm sorry. But I really don't think Musashi would be like that, right Conan."

"Yeah." Conan naturally agreed with what Mao Lilan said.

However, they did not expect that that night, when Tsutsumi and his wife were driving home, they saw Nakatani Yoshiko sitting on the ground waving a stick, trying to repel Musashi, while Musashi was yelling at Nakatani Yoshiko with a fierce look on his face.

What the Tsutsumi couple didn't expect was that after they drove Musashi away, Nakatani Raiko pointed to the side and said in horror: "My mother-in-law, my mother-in-law, she..."

Then, Mr. and Mrs. Tsutsumi looked in the direction that Nakatani Yoshiko pointed, and saw Nakatani Yoshiko's mother-in-law, Nakatani Kinue, lying on the ground with a pool of blood under the back of her head.

What made the two even more panicked was that Musashi was still licking Nakatani Kinue's neck at this time, and there was an obvious dog tooth mark on Nakatani Kinue's neck.

Seeing this scene, Tsutsumi Eisuke felt something was wrong and ran over quickly, only to find that Nakatani Kinue was already dead.

Seeing this, Mr. and Mrs. Tsutsumi were shocked and called the police. At the same time, Nakatani Raiko also called Kogoro Mori over.

It is said that Nakatani Raiko's right foot was sprained during the confrontation with Musashi, so when Aoki Matsu arrived, medical staff were examining and bandaging her.

"Okay, it's been bandaged." said the medical staff.

Nakatani Raiko asked in a somewhat depressed mood: "Well, how many days will it take for me to be able to walk normally again?"

"Well, because your sprain is quite serious, it will take at least four or five days." The medical staff thought for a moment and replied.

The medical staff then left the scene.

Seeing this, Aoki Matsu immediately stepped forward, looked at Nakatani Raiko and asked, "Mrs. Nakatani, could you please explain the situation in detail?"

"Okay." Nakatani Raiko responded, then recalled and said, "My husband was not at home this evening, and my mother-in-law came to our house to play. When I served her coffee, I knocked over the cup and stained her clothes, so I lent her my sweater.

Then I remembered that I hadn't collected the clothes that were hung outside, so I went to collect them. As a result, I accidentally dropped my husband's shirt into the yard next door. Unfortunately, the dog named Musashi was attracted by it and took the shirt away.

I saw that there seemed to be no one next door. Although I wanted to go get the clothes, I was afraid of Musashi and didn't dare to go. As a result, my mother-in-law said that she wanted to go get the clothes back. I told her that it was dangerous and kept trying to stop her, but she said it was okay because she had seen the dog since she was a child.

So she opened the fence gate and walked over, saying to Musashi, "Little Musashi, be good," and reached out to take the shirt. Unexpectedly, Musashi suddenly went crazy at this time, knocked her mother-in-law to the ground, and bit her neck.

By the time I realized what was happening and rushed forward to chase Musashi away, my mother-in-law was already dead. Musashi was still baring his teeth and roaring at me, and I was terrified. I subconsciously took out the firecrackers in my pocket and quickly stood up to run away, but I sprained my ankle and fell to the ground.

Musashi turned back and I was terrified. Fortunately, Tsutsumi and his wife arrived just in time and drove Musashi away. "

Tsutsumi Eisuke responded, "Yes, we were supposed to be late tonight because of the party, but my wife was not feeling well during the party, so we came back earlier than scheduled."

Nakatani Laizi heard this and said with some relief: "But I also saved my life because of this."

"Is that so?" Aoki Matsu nodded, but in his heart he didn't believe what Nakatani Raiko said at all.

As we all know, "Detective Conan" is an animation for all ages, so there are several iron rules that override science.

What iron rule?

1. The kidnapped children will never be killed and will definitely be rescued by Conan.

2. There are no cases of rape of women.

3. Animals are very cute and will never commit crimes subjectively. Someone must be using animals to commit crimes!

4. There is absolutely no case without any flaws.

So it is clear who the murderer in this case is.

Nakatani Raiko was the murderer who killed her mother-in-law, and the motive was most likely the bad relationship between the mother-in-law and daughter-in-law.

Aoki Matsu has already guessed almost exactly how this woman committed the crime.

The high probability is that he deliberately wore certain clothes and held a cane to treat Musashi badly, or even hit him, causing Musashi to have a stress response.

Animals' IQs are naturally not as high as humans', but they are not fools. If someone treats them badly, they will definitely remember it. Some animals with slightly higher IQs will even seek "revenge."

Of course, this kind of revenge does not involve killing people, but rather shitting or peeing in front of the other person's door.

After Musashi formed a stress response, Nakatani Yoshiko deliberately went to Uncle Mori to seek help, in order to deepen everyone's impression that Musashi was a vicious dog.

The next step was to find a good opportunity, deliberately knock over the coffee cup, let the mother-in-law change into her own clothes, and then induce Musashi to go crazy and pounce on the victim to bite him.

Of course, it is also possible that Nakatani Yoshiko killed the victim herself and just left the body there.

The problem is, if we want to convict Nakatani Raiko, we can't just do it based on what Aoki Matsu says is an iron law of the world. We have to find evidence.

"Can I ask you something? What is that crutch?" Aoki Matsu asked, pointing at the crutch placed next to Nakatani Raiko.

Nakatani Raiko looked in the direction of Aoki Matsu's finger, and then explained: "This, because my mother-in-law is used to using a walking stick, so this is an extra spare item we bought."

"What about the firecrackers?" asked Miwako Sato on the side.

Because the case involves women, Inspector Megure also sent Sato Miwako over.

Nakatani Raiko took out a few firecrackers from her trouser pocket and explained, "I carry these because I'm afraid of being attacked by Musashi. I heard that dogs are afraid of the sound of firecrackers."

"Please give these to me." Sato Miwako stepped forward and said.

"Okay." Nakatani Raiko handed all the firecrackers to Sato Miwako.

Then she looked at Aoki Matsu with a serious face and said, "Mr. Officer, my mother-in-law must have been attacked by Musashi because she was wearing my sweater and was mistaken for me."

Then, without waiting for Aoki Matsu to say anything, Nakatani Raiko pointed her finger at Maori Kogoro who was standing beside her and said, "That's why I went to you for help at that time."

Maori Kogoro was accused by the other party, feeling somewhat helpless and wronged, and could only say brightly: "But you can't say that."

At this time, Aoki Matsu looked at Nakatani Raiko and said, "Mrs. Nakatani, please don't be so excited. Please wait in the living room for a moment. I will go to check the scene."

According to the iron rules 3 and 4 set by the old thief Aoyama, there must be flaws in this case, and the murderer definitely cannot be that dog Musashi.

Aoki Matsu walked over to Nakatani Kinue's body and looked at her wounds.

Suddenly I felt a little strange.

Qing Musong had seen dog bite wounds before, but that was in his previous life. However, it was not him who was bitten, but his friend.

Generally speaking, when a dog bites a person, it will leave two types of wounds.

One is a "superficial bite" wound, which is loosened after one bite. The skin may break and bleed, but there are only neat teeth marks and the wound is not particularly deep. The other is a large bite wound.

In most cases, canines prefer to bite people's limbs. They will rush over and bite the legs directly, rather than knocking the person down and biting the neck.

Only cats like to bite the neck, lock the throat and bite deeply until the prey dies.

This is a biological habit of different species, and most animals will do this unless they are specifically trained.

But there is something wrong with the wound on Nakatani Junjiang's neck.

Not to mention that Musashi pounced on him and bit his neck, the wound alone was quite deep, and dogs don't like to bite too deep, they prefer to bite and tear.

Qing Musong thought for a moment, and then instructed the detective from the forensic department, "Do a blood test on the body to see if there are any drug components. Also do a comparison of Musashi's tooth marks and wounds."

If Aoki Matsu was Nakatani Raiko, in order to ensure that she could kill her mother-in-law 100%, she would definitely not rely solely on Musashi.

After all, she didn't say that Nakatani Kinue grew up watching Musashi. What if the smell of her clothes didn't cover the smell of Nakatani Kinue, and Musashi recognized Nakatani Kinue and turned around to help Nakatani Kinue, then Nakatani Raiko would be doomed.

In this case, in order to ensure a 100% success rate, it is very likely to give Nakatani Kinue some sleeping pills, motion sickness pills or the like in advance to ensure that she has no ability to resist.

"Yes!" the forensic officer responded.

Then Aoki Matsu walked to another scene - where Nakatani Raiko fell.

There is a distance of twenty to thirty meters between the two places.

There are two evidence signs here, indicating two bloodstains on the ground.

Nakatani Raiko only sprained her right foot and there were no wounds on her body that would bleed, so this should be the blood of the deceased Nakatani Kinue.

But the problem is that Nakatani June's body fell about 20 to 30 meters away. Even if blood was spurting out, it couldn't fly that far!

What's more, the shape of the blood on the ground is not the shape of blood spurting out, but the shape of dripping down drop by drop.

Even if Nakatani Raiko saw that the deceased was dead and touched blood when she ran over to check, it is impossible for the blood to be as much as that on her body, and that it would suddenly drip onto the ground after she ran twenty or thirty meters.

If the blood was on the crutch, it should have been thrown to the ground when it was swung at Musashi, and should have been in front of Nakatani Raiko, not behind her.

After Nakatani Kinue fell there and died, her body did not move on its own, nor did it spurt blood. It was impossible that it was stained by Nakatani Raiko, so what could have happened to cause blood to drip here?

It is known that the murderer who killed Nakatani Kinue was not Musashi, but Nakatani Yoriko.

Then she should not have expected that she would sprain her foot. Otherwise, considering how much Musashi hated her, he might really bite her, which was definitely not the result that Nakatani Raiko wanted to see.

Mr. and Mrs. Tsutsumi returned home early tonight. It is very likely that because they returned home early, Nakatani Raiko was forced to shorten the time to commit the crime, and in her hurry, she sprained her foot.

This raises a question: why was Nakatani Raiko in such a hurry?

According to the descriptions of both parties at the time, when the Tsutsumi couple drove to the gate, Nakatani Raiko had already killed Nakatani Kinue.

There was no need for her to rush.

Unless...she was holding something in her hand or on her body that could incriminate her!

She was in a hurry to hide, so when she heard the sound of Tsutei Ying's car, she panicked, sprained her foot and fell to the ground.

Such a thing was most likely stained with the victim's blood, because she fell to the ground and the blood dripped down.

Something bloody.

Considering the strange wound on the neck of the deceased Nakatani Kinue and the bloodstains behind where Nakatani Raiko fell, Aoki Matsu thought of something - a canine tooth model!

Thinking of this, Qing Musong quickly called people to search around the bloodstain, especially in the bushes not far away.

A few minutes later, a police officer said to Qing Musong excitedly: "Inspector, we found it."

Qing Musong hurried over to take a look, and indeed saw a canine tooth model covered in blood.

What made Aoki Matsu and others even more excited was that there was a blood-stained fingerprint on the canine tooth model.

This is irrefutable evidence.

After taking photos to collect evidence, Aoki Matsu carefully put the canine tooth model into the evidence bag.

Aoki Matsu handed the evidence bag to Maruta Ayumi, then walked into the living room and said to everyone, "We have already investigated the scene. Mrs. Nakatani, your mother-in-law's death was not caused by Musashi. You killed your mother-in-law yourself and want to put the blame on Musashi who can't speak for himself, right?"

"What!" Everyone present was shocked.

Nakatani Raiko's face changed drastically when she heard this. "What nonsense are you talking about? How could I possibly kill my mother-in-law? It was clearly Musashi who pounced on my mother-in-law and killed her."

"First of all, when canines attack humans, they target the thighs. Only cats will lock the throat. Secondly, we found this in the bushes near your house." Aoki Matsu motioned to Maruta Ayumi to take out the thing.

Looking at the things in the evidence bag, Mao Lilan asked in confusion: "What is this?!"

"Canine tooth model!" Aoki Matsu looked at Nakatani Raiko and said, "I think it should be made based on Musashi's canine teeth. On this one, we found a bloody fingerprint. It should be yours, Mrs. Nakatani, right?"

After seeing the canine tooth model, Nakatani Raiko lowered her head and remained silent.

"I remember now!" After seeing the canine tooth model, Tsutsumi Eisuke patted his knee and said, "One day before, when I was brushing Musashi's teeth, I found clay on his teeth. I was very surprised at the time, wondering how there could be clay on them when there was no clay nearby."

"That should be what Mrs. Nakatani did in order to get Musashi's tooth mark." Aoki Matsu looked at Nakatani Raiko and said.
