Nine months after their only son, Hoon "Scott" Kang, a Korean-American tourist, died from severe head injuries sustained in the stairwell of a building in Kabuki-cho, his family and friends are still no closer to understanding how he died.

Although the Shinjuku police have officially opened an investigation into Scott's death, the family has been told only that the investigation is "not complete."

"Despite strenuous efforts to reach Japanese authority through diplomatic means and a channel in Japan to the Shinjuku police in Tokyo, we have heard nothing about progress in the investigation, and have received no response from the Japanese government," says Kang family spokesman Raymond Wozniak.
