find my first and last friend

Lest! I could find my first and last friend namely "Kon Hiromi". She graduated from Sofia University (Joshi Daigaku), Tokyo in 1984 or 1985. She used to live in Yokohama city and later on joined KLM airline as an air-hostess. I wonder, if someone can help me to find out her where about. This will be a great favor to me, Onegai.
