Unfortunately, for people who are doctors by profession and are used to wearing gloves often, it is simply impossible to leave fingerprints. Officer Twilight didn't have much hope for that, he just hoped that he could find something like hair here. However, although no hair was found, a piece of music was found on the floor.

After Officer Twilight examines the body of Kei Suzuki, he returns downstairs again. At this time, in addition to Dr. Asai, who was locked up, there were five people who were suspected after the discovery of Mr. Kawashima's death. After putting all five of them together, Kei Suzuki glanced at Officer Twilight and asked like the five people, "Is there any relationship between Mr. Kawashima, who died yesterday, and the head of Kuroiwa Village, who was just killed today?" Why were they killed one after the other? At the same time, there is a piece of music next to the corpse? ”

"Sheet music?" After hearing this word, the bearded and dirty Nishimoto Kenden exclaimed loudly, "It's that guy, Keiji Aso, that guy is still alive." ”

Just as Ken Nishimoto was yelling, a voice suddenly came in from outside the house. With this voice, the old policeman from Moonshadow Island also walked in and said, "He is indeed dead, the bones and teeth found at the scene of the fire at that time have also been compared, it is their family." That's true! Everything at the scene of the fire was burned down, except for the sheet music that remained in the fireproof safe. ”

"Sheet ......" Three voices rang out, namely Ken Nishimoto, Officer Twilight, and Kogoro Mori.

Mori Kogoro didn't realize it at all, and before Officer Twilight could speak, he ran out and said, "Where?" Where are those scores? ”

The old policeman was taken aback by the momentum of Mori Kogoro and Officer Twilight, and whispered, "It's in the warehouse of the public hall, but the key to the warehouse is in the police station." ”

Officer Twilight leaned closer than Mori Kogoro and yelled at the old officer, "Then why don't you go and get it?" Just go! ”

"Yes!" The old policeman answered loudly and was about to leave.

It was at this time that Kei Suzuki interjected, "Wait, Officer Twilight. Let's first understand the relationship between the two deceased, and the score can be picked up after we understand this information. ”

Officer Twilight also remembered what he was talking about at this time, so he coughed dryly and said, "Ahem, too." ”

The old policeman of Tsukikage Island said, "Actually, Mr. Kawashima, the head of Kuroiwa Village, and the former village head, Mr. Kameyama, who died two years ago, and Mr. Nishimoto are actually friends who grew up with Keiji Aso, who was burned to death twelve years ago. Twelve years ago, after Keiji Aso was burned to death, it was also found by the four of them together. ”

Speaking of which, not only Kei Suzuki, but also Officer Twilight and Kogoro Mori were aware of the problem. After the death of Keiji Aso, these four first witnesses actually died around the past two years, which is obviously abnormal.

At this time, Kei Suzuki asked again: "May I ask how many people are in Keiji Aso's family?" Are they all burned to death? ”

The old policeman recalled: "Huh? There are four people in their family, right? However, only three people were burned to death, their husband and wife and their daughter. Their son had been hospitalized because of a serious illness when he was a child. His name seems to be Sung Si. ”

"Chengshi!" Kei Suzuki and Officer Twilight glanced at each other, and they both thought of the doctor in another room at this time, dressed as a man, Narumi Asai.

Thinking of this, Kei Suzuki asked, "Officer Twilight, hasn't there been any news from Tokyo?" ”

Officer Twilight took out his phone and was about to say something, when Officer Twilight's phone rang. After seeing the phone number, Officer Twilight nodded to Kei Suzuki, and Kei Suzuki knew that the news he was waiting for had arrived when he saw Officer Twilight's gesture. Seeing this, Kei Suzuki said to the waiting Moon Shadow Island policeman, "Officer, can you please find the key to the warehouse?" ”

"Yes!" After hearing Suzuki Kei's order, the old policeman quickly left after saluting.

After the old policeman left, Officer Twilight nodded to Kei Suzuki and said, "That's right, Brother Suzuki." Just called from Tokyo, Dr. Asai was adopted and changed his name, and his real name turned out to be Minoru Aso, the son of musician Keiji Aso, who was killed on Tsukage Island twelve years ago. ”

Kei Suzuki nodded, "In this case, the doctor has a motive to kill these people." And in the two murders, he did not have an alibi, so his suspicion was even greater. And there's also Ken Nishimoto, who seems to be related to the murder of 12 years ago, and I'm still here, Officer Twilight, so we've done a great job this time. It not only solved the serial murder incident, but also solved the murder case twelve years ago, and by the way, also cracked a trafficker. Poison cases. ”

Officer Twilight muttered, "Mr. Nishimoto didn't say a word at all, but now I don't believe he can remain as silent as he did just now. Now all we have to do is open his mouth and learn from him what happened twelve years ago. ”

Conan heard the conversation between Kei Suzuki and Officer Twilight, and pursed his lips very dissatisfied, and said to himself, "Cut, my reasoning is useless at all!" With this cheating guy here, you can find the murderer directly, as long as you find a little clue. ”

This time there was a direction, and Officer Twilight quickly pulled out the truth from Ken Nishimoto's mouth from twelve years ago.

It turned out that twelve years ago, Keiji Aso, who was a musician, took the opportunity to perform abroad and brought poison from abroad. Taste back. They have been cooperating many times, but just twelve years ago, Keiji Aso's youngest son had a serious illness, but after being hospitalized, Keiji Aso suddenly said that he didn't want to continue selling. Poisoned.

But because they were afraid that this matter would be leaked, the four of them, Kameyama, Kawashima, Kuroiwa, and Nishimoto, had murderous intent. One night twelve years ago, the four of them blocked the Aso family in their home and burned them to death in a fire. And the only one who escaped was his youngest son, who was sent to Tokyo for hospitalization because he was sick.

At first, some of them wanted to kill Ajimi in the Tokyo hospital, but they didn't come to the end due to a disagreement.

Kei Suzuki walked into the room where Dr. Asai was locked up again, but this time almost everyone went in with him, and as soon as he walked into the room, Kei Suzuki said: "Mr. Aso Minoru, we have already found out what happened, you are the youngest son of the musician Keiji Aso, who sold drugs with the people you killed twelve years ago, and then was killed by those accomplices. The reason why you want to kill them this time is also to avenge your father, right? ”

After hearing Kei Suzuki's words, Asa Minoru, who had been bowing his head, slowly raised his head. At this time, he also saw Ken Nishimoto outside the room, with his hands cuffed. After seeing this situation, how did Aso Minoru not know the current situation? Ken Nishimoto has confessed what happened back then, and now he has been formally arrested. was arrested along with Ken Nishimoto, as well as Hirata, the secretary of the village chief.

So Asumi Minoru also slowly said his confession: "Actually, I have been suspicious of my father's death since before. After graduating from university, I came back here as a doctor. Then one day, when I told my former village chief, Kameyama, my true identity, he suddenly talked to himself in fear, and then died of heart palsy. ”

"At that time, I was playing my father's favorite moonlight as his funeral music. Later, I heard people in the village talk about the situation in my family back then, and this incident made me have the idea of killing the other three people as well. ”
