Family and friends of Hoon "Scott" Kang say the 19-year-old's death in Tokyo in August left too many questions unanswered and are seeking ways to shed more light on the case.

Kang, an American of Korean descent from Buford, Ga., was found unconscious and bleeding from severe head wounds in the early hours of Aug. 25 in an emergency stairwell in a building in Shinjuku's seedy Kabukicho district.

Kang, who was vacationing in Japan with two other friends, died five days later after being hospitalized. He never woke from his coma.
