Feb. 7, 1976, should have been just another Saturday for Susumu Fujita.

The 19-year-old college student was leaving his house in Kawaguchi, Saitama Prefecture, for a part-time job as a security guard in Tokyo's Shinjuku Ward. When his father asked if there was any laundry, Fujita answered, "I'll do that tomorrow because I'll be off."

That was the last conversation he had with his family before he disappeared.
