In Conan, people have a brain option system.

Chapter 3: There is no doubt that this is murder
Conan and Sera Masumi followed detective Sato Miwako to the national highway opposite the apartment where they were originally staying.

This is the scene of the car accident that happened when they were arresting the criminal just now.

"Yumi!"

"Meiwako, you came so quickly!"

A beautiful traffic policewoman named Yumi Miyamoto ran over here while greeting Miwako Sato.

And when she saw Conan and Sera Masumi getting out of Sato Miwako's police car, a look of surprise appeared on Yumi Miyamoto's pretty face.

"This is little brother Conan, and Miss Sera...?"

"Hello, Officer Miyamoto~"

Conan greeted Yumi Miyamoto sweetly in his childish voice.

And next to her, Masumi Sera crossed her chest with one hand and stroked her chin with the other, looking at Yumi Miyamoto in front of her with interest.

"So this is Miss Miyamoto who has bewitched Hideyoshi-san so much. She is really beautiful."

Yumi Miyamoto is the fiancée of Sera Masumi's second brother, Haneda Hideyoshi, and Sera Masumi only heard the news recently.

Yumi Miyamoto felt a little frightened by the gaze of Masumi Sera.

She turned her gaze to Sato Miwako, and her beautiful crescent eyebrows slightly frowned.

"Miwako, have you already disclosed the situation to the detective?"

Unless there is a difficult case to solve, the Metropolitan Police Department generally will not allow outsiders to interfere in the investigation.

As soon as Sato Miwako heard that it was a murder case, she brought a detective over. If this were to get out, wouldn't it make the Metropolitan Police Department seem very incompetent, as they had to ask detectives for help first when anything happened?

"No, Officer Sato didn't tell us about the situation here. We asked Officer Sato to bring us here."

Conan used his innocent voice to answer Miyamoto Yumi's question before Sato Miwako.

"Eh?"

Yumi Miyamoto was stunned.

She didn't understand, since Sato Miwako didn't reveal any information about the case, why did they follow her?

To outsiders, shouldn't this be just an ordinary traffic accident?

"Officer Sato is from the First Investigation Division, a criminal police officer specializing in homicide cases. Since Officer Sato is rushing here, there is a high probability that a murder has occurred."

Conan saw Yumi Miyamoto's confusion and said with a smile.

"Could it be possible that she was simply called over because Miwako was nearby?"

"If it was just a common incident, there would be no need to trouble a deputy inspector like Officer Sato to come all the way here."

Miwako Sato, a policewoman in the Metropolitan Police Department, is a deputy inspector, and her rank is second only to Inspector Megure.

If it is just an ordinary case, at most, an inspector general like Takagi Shigeru or Chiba Kazunobu would be sent over.

"Hmm?" Miyamoto Yumi moved closer to Conan with a suspicious look on her face. "How can a primary school student like you know so much about the Metropolitan Police Department?"

"Uh... this is what Sister Sera told me."

Conan realized that he couldn't help but say something unnecessary, so he quickly put the blame on Masumi Sera who was standing beside him.

Yumi Miyamoto had no doubts about this, after all, Masumi Sera was also a well-known detective.

"Don't waste time. What happened to the person that Yumi said was stabbed to death?"

Sato Miwako interrupted those who had seriously strayed from the topic with a serious look on her face.

Yumi Miyamoto also came to her senses and led everyone towards the scene of the car accident.

"The cause of the accident was that the K-Car (light automobile) in the front suddenly braked, resulting in a chain collision of several vehicles."

"The 'culprit' car at the front lost its balance after being rear-ended and hit the roadside guardrail, so the damage was quite serious."

Miyamoto Yumi said as she led everyone to the driver's seat of the car in front. "But when I went over to check on the driver and passengers, I saw this scene—"

At this time, everyone who finally saw the situation inside the car clearly couldn't help but turn pale.

The woman in the driving seat had her head tilted to one side, her body covered in blood.

The woman's neck, chest, and abdomen were covered with wounds.

There was even a dagger stuck in his abdomen.

"Dead."

After reaching out to feel the pulse of the woman in the driving seat, Miwako Sato shook her head.

Masumi Sera came to the woman's side, put on the white gloves borrowed from Miwako Sato, carefully lifted the woman's clothes, and began to observe the woman's wound.

"Almost all of the wounds had signs of life around them, which means the woman did not die in a car accident, but from a knife wound."

"There is no doubt that this was murder."

"Just looking at the number of wounds and the force of the cuts, we can tell that the murderer must have a great hatred for the victim."

"If nothing unexpected happens, this should be a premeditated murder."

Everyone had no objection to Sera Masumi's reasoning.

After all, there aren’t that many people with road rage who would kill someone if an accident happened after they just picked up a new car.

"So the next step is to see if the deceased left any death message, and ask the car owners behind if they saw the murderer..."

Conan muttered to himself, and stood on tiptoe to take a look inside the car.

However, this one glance made his eyes suddenly widen.

He noticed that the interior of the car was covered in blood, but the passenger seat was the only area with minimal blood.

Conan quickly looked at Miyamoto Yumi and asked loudly:

"Officer Miyamoto, did you see the passenger in the passenger seat?"

"Ah, Conan, how do you know there's someone in the passenger seat?"

Yumi Miyamoto was puzzled.

"There was a young male passenger in the passenger seat. We thought he was dead, but after checking, we found he was not dead, but his condition was not good. So Miaozi and I got him out of the car. Now he lies over there."

Yumi Miyamoto turned her head to the side, and everyone looked in the direction she was looking, and sure enough, they saw a man covered in blood lying on the ground.

Next to him, another traffic police officer, Miike Naeko, was anxiously making a phone call.

Conan, Sato Miwako and Sera Masumi were all surprised when they heard this.

Sera Masumi couldn't help but ask directly:
"Ms. Miyamoto, if it is determined that this is a murder case and not a simple accident, isn't it the most important thing to protect the crime scene?"

Now that it has been confirmed that there was someone in the passenger seat, the biggest suspect in the murder is self-evident.

However, Yumi Miyamoto and Naeko Miike took the suspect out of the car before the police arrived, so the crime scene was likely to be destroyed.

"Of course I know about this kind of thing."

"Then why...?"

After Sera Masumi blurted out the question, he also had some guesses in his mind.

Although Yumi Miyamoto wanted to protect the scene, she still took the biggest suspect out of the car.
That meant she had a reason to take the risk of ruining the scene and get the other person out of the car.

Looking at the car's stopped engine, a guess arose in Sera Masumi's mind.

"Officer Miyamoto, there is a carbon monoxide leak in the car, right?" Conan looked at Yumi Miyamoto and said in a deep voice.
