Autopsy Confirms Asphyxia in Hokkaido Bar Wall Case as Saitama Suspect Is Sent to Prosecutors

Police shift from abandonment allegations toward potential homicide in cases involving acquaintances.

Overview

  • The Hokkaido Prefectural Police said a judicial autopsy found the woman discovered hidden in a Hidaka bar died of neck compression causing asphyxia.
  • Bar owner Toshihiko Matsukura, 49, arrested on suspicion of abandoning a corpse, was referred to the Sapporo prosecutors, and investigators are working to confirm the victim’s identity.
  • The body in Hidaka was concealed in a roughly one-tatami-sized recess low in a wall with the opening boarded over, and the victim is believed to be a woman missing since December 31.
  • In Saitama, company employee Sanae Yamamoto, 51, was found dead in a Niiza apartment, and Shin Yamaguchi, 53, was arrested on a corpse-abandonment charge and sent to prosecutors.
  • Investigative sources say Yamaguchi told police he struck Yamamoto and forced her into a car, while a forensic exam points to suspected asphyxiation as officers probe motive and possible homicide.
