In a case where a regular customer's office worker was arrested for murdering a 25-year-old owner's woman at a karaoke pub in Kita-ku, Osaka, it was discovered that the store key had been lost from the scene.
When the body was found, the store was locked, and police are investigating it, considering that it may have been taken away to delay the discovery of the incident.
Hiroshi Miyamoto, a 56-year-old office worker in Nishinomiya City, Hyogo Prefecture, stabbed the owner Mayuko Inada (25) with a knife inside a karaoke pub in Tenjinbashi, Kita-ku, Osaka on the night of the 11th of this month. He was arrested for murder and sent to the Osaka District Prosecutor's Office on the afternoon of the 19th.
He denied the charges by stating to the police that he had gone to the store but did not.
According to police, when the body was found on the 14th of this month, three days after the incident, the entrance to the store was locked, but subsequent investigations revealed that the key had been lost.
Police are investigating further, suspecting that they may have taken it away to delay the discovery of the incident.
