Mos Burger: Where the branch manager and part-time staff discovered Asaki’s body (bottom).
Both the police department and prosecutors concluded that: “Asaki’s case could not be (anything) other than a suicide” and that the “probability of suicide is too high.” Their main findings:

1. Her body contained no trace of injuries that would indicate she was pushed from the building
2.   Her clothes were not ripped another important indication to police that she was not involved in a struggle prior to falling from the building
3.   She landed very closely to the exterior wall of the building – which police found consistent with other suicide attempts
4.   When the person who discovered Asaki asked her, “Have you fallen?” she replied, “I am okay”
5.   When the person who discovered Asaki asked her, “Shall I call the ambulance?” she replied, “I don’t need that”
6.   No one saw a suspicious person or car near the scene

Of all the above-mentioned facts, police and prosecutors believe Asaki’s refusal for an ambulance served as the strongest indication that she committed suicide. This analysis was widely known and published in newspaper reports directly following Asaki’s death. However, magazines such as Shukan Shincho concealed these findings and began to promote the alleged murder plot.
