Chapter 811 Exchange of Killings

"Have you confirmed your identity?"

Gunma Prefecture Police Headquarters

Nobuhiro didn't expect that he was just going to do a favor and actually abducted him to Gunma County.

"It has been confirmed. Based on the dental information of the deceased, we found that he was 28-year-old Kojima Yuta, who was born in Gunma Prefecture." Yamada Rokuha read against the information recorded in the police manual.

"What does he have to do with the corpse of the convenience store man?" Toru Amuro asked.

Nobushige reminded him in a low voice: "He has a name, Matsukawazuka Komachi."

"Okay, Matsukawazuka Komachi, so does Mr. Yuta Kojima know Matsukawazuka Komachi?" Toru Amuro repeated the question in a polite manner.

"We don't have any relevant information about their acquaintance yet..." Yamada Rokuha paused, then suddenly smiled at Nobushige and said, "There is a clue that you may be interested in."

"What?"

"We found out that Yuta Kojima has been secretly working as a debt collector for a certain loan shark company. In order to collect the debt, he once participated in beating an old man to brain death. At the beginning of this year, he was just released from prison after serving his sentence."

"So, there should be many people who have the motive to kill him. Are there no suspects among these people?"

Yamada Rokuye said regretfully: "It's not that there is none, it's just a pity that they all have alibis."

Hearing this, Yamamura Cao looked over and said: "There is a person who is still in the hands of the Tokyo Metropolitan Police Department, but he was not in Gunma County when the crime occurred. The alibi is perfect."

"What a perfect alibi..." Nobuhiro shook his head and sighed, and asked, "Who is this person?"

Perhaps because he had been with Conan for a long time, Nobuhiro's thoughts were now heading in a strange direction. The more perfect the alibi was, the more Nobuhiro suspected there was something fishy going on.

Yamamura Cao chuckled: "Liuye-san probably hates that person."

Yamada Liuye was confused: "Why should I hate him?"

"Because Honda Teruyoshi's grandfather was the old man who was beaten to death by Yuta Kojima." Yamamura Soo looked at Yamada Rokuha, "Do you still remember Honda Teruyoshi?"

"Of course!!" Yamada Rokuha gritted his teeth and said, "He was the one who smashed my car window and stole my satchel, causing me to be suspected by the Tokyo Metropolitan Police Department but unable to prove my identity. The car was not used for reasons. My business was damaged and I can’t apply for compensation. I’m so angry!”

Eh eh eh?

After hearing the words of Yamamura Cao and Yamada Rokuha, Nobushige suddenly discovered a new world.

A man with murderous motives for the corpse of a man in a national park actually appeared near the corpse of a man in a convenience store, and Nobushige once suspected that he was the murderer of the corpse of a man in a convenience store.

A perfect alibi, appearing at the wrong time and place, these clues seem to point to a classic criminal method.

"Police Officer Yamamura," Nobushige said, "Can you please investigate Nana Nakazato?"

Yamamura Cao was confused: "Nakazato Nana... wasn't she drinking with her friends when Matsukawa Tsukakomachi was killed?"

Nobushige shook his head: "It is not the connection between Rinana and Matsukawazuka Komachi's case under investigation. I hope the police can investigate her as a suspect in the murder of Yuta Kojima."

Yamamura Cao was stunned: "Why?"

"Ah, I know!" Yamada Liuye slapped his thigh suddenly.

"Ah - it hurts!" Yamamura was almost in tears. He stared at Yamada Rokuye and complained, "If you want to hit, just hit your own leg. Why do you hit me?!"

"Sorry." Yamada Rokuha said sorry insincerely, "I understand, Mr. Asano. Are you talking about exchange killing?"

"Hiss..." Yamamura took half a step back subconsciously.

I didn't expect that such a terrifying thing could happen in the small Gunma County. It would be fine if it was just two people exchanging killings, but if there were more people involved... tsk tsk.

The so-called exchange killing, as the name suggests, is to exchange killing objects with others.

Due to the limitations of manpower and material resources, the police often start their investigation from the connections close to the victim. A "stranger" who is far away in another city and has no motive will not enter the police's sight. This gives some criminals room to operate. They will contact other people planning murders through the Internet and other methods, and exchange targets with each other.

In this way, when the victim is killed, the suspect who has a grudge against him can create the most perfect alibi for himself and dispel the suspicion of the police.

However, although exchange killing is an excellent method for murderers, the probability of exchange killing has always been very low. On the one hand, many murders are committed on impulse, and few people plan for long periods of time. On the other hand, it is difficult to contact a collaborator who is also determined to commit murder, and that collaborator must also be highly trustworthy. Otherwise, you help him kill someone, but he turns around and reports you. The consequences would be too harsh.

This is often the case when solving a case. Once the key is figured out, the rest of the matter will fall into place naturally and smoothly.

The police in Gunma Prefecture immediately contacted the Metropolitan Police Department and discussed the two cases together, and soon discovered the clues.

Seeing that the police had already figured out how to solve the case, Nobushige offered to leave. After all, it was already night and it would still take a few hours to get back to Tokyo from Gunma Prefecture.

"Thank you so much to you and Mr. Amuro for today." Rokuha Yamada bowed to Nobushige sincerely and thanked him.

"You're welcome, this is what I should do." Nobuhiro smiled, "If you have any trouble with the case in the future, please feel free to call the Maori Detective Agency at any time."

"Every commission that Detective Mori takes must be charged, right? Can I call you?" Yamada Rokuha blinked, pretending to be naughty and cute.

However, Nobuhiro not only was not attracted, he even felt that Yamada Rokuha wanted the services of the prostitution agency.

How unreasonable!

What about Toru Amuro? As a member of the Maori Detective Agency, how could he be absent when it was time to protect the interests of the agency?

Nobushige looked around and found Toru Amuro at the door whose patience was gradually disappearing and who just wanted to go back as soon as possible.

Feeling Asano Nobushige's condemning gaze, Toru Amuro curled his lips and said, "Miss Rokuye has made such a sincere request, how can you have the heart to refuse?"

Nobuhiro: "..."

Okay, you better shut up.

Yamada Rokuha laughed happily when he saw this: "Okay, okay, it's just a joke. But as compensation, can you tell me how you found the body in Oze National Park today?"

Nobuhiro had no intention of hiding this from them, so he naturally explained: "Because of the methane."

"Swamp gas?"

"right."

After the corpse is buried in the soil, it will decay and produce biogas. This gas gradually seeps out from the soil and inhibits the survival conditions of nearby plants. Therefore, the plants around the corpse were all yellow and shriveled, which was very obvious.
