In October last year, five men and women, including a gangster executive, were arrested on suspicion of abandoning the bodies of a 46-year-old man found in a fire protection tank in Inzai City, Chiba Prefecture.

The people arrested were Tadashi Nakagami (49), a self-proclaimed and unemployed person with an unspecified address, and Yoshinobu Deguchi (53), a self-proclaimed and unemployed person in Yachiyo City, and a Sumiyoshi-kai-affiliated gangster executive in Shinjuku-ku, Tokyo. There are five men and women, including Yoshiaki Mori (63).



According to police, the five were suspected of abandoning the body of Kosuke Miyauchi (46), a transportation company in Narita City, in a fire protection tank in Inzai City, Chiba Prefecture last October.



The police were investigating on suspicion of murder because there was a cut on Mr. Miyauchi's neck, but as a result of investigating the security camera near the scene and Mr. Miyauchi's friendship, it is suspected that five people were involved. It turns out that there is.



The approval or disapproval of the five has not been disclosed.



The police will also investigate in detail how Mr. Miyauchi was killed.
