Stephen Mckee was last seen by his sister before he left to teach English in Vietnam. He was in contact with her periodically. Stephen became ill in Cambodia, and once in good health he returned to Ho Chi Minh City, Vietnam. He told his sister he wanted to return to Australia, then the call cut out and she has not heard from him since.
