Tezuka Renichi did not go into detail. He simply told Duanmu Huai to watch the news, but Duanmu Huai could not be bothered with secondhand news, so he called the police station directly and learned the whole story.
Strictly speaking, this case was somewhat related to Duanmu Huai.
At the time, he had caused a huge commotion in Kamurocho, sending all those members of the Dojima Family to the hospital. The police had to maintain order and inspect the situation in various places. As a result, someone reported finding a corpse in an empty lot in the Shopping Street. The police rushed over to investigate and discovered the victim.
However, the police had not linked the victim to Duanmu Huai. After all, Duanmu Huai had only just arrived in Kamurocho at the time, and the murder scene was quite far away. Later, based on their inquiries, the police confirmed that before his death, the victim had gotten into a conflict with a member of the Dojima Family over debt collection. Someone had also seen him force the victim into that empty lot.
The autopsy showed that the victim had been violently beaten. The police currently believed that one of the Dojima Family's underlings had probably gone too far while collecting a debt and accidentally beaten the man to death—such things happened often enough.
The incident should originally have been reported last night, but Duanmu Huai's rampage in Kamurocho had taken the headlines, pushing this matter out of the spotlight. In that respect, the police even had to thank Duanmu Huai.
After all, beating up a group of gangsters was just entertainment, but a death was another matter entirely. Most of the media were still focused on the brawl between Duanmu Huai and the Dojima Family and had paid no attention
