On Easter Sunday, April 2, 1972, 16-year-old Nancy Carol Fitzgerald sat down for dinner with her family in North Jersey.

The next day, she disappeared, and was never seen or heard from again.

Following an intensive long-term investigation involving numerous interviews and extensive DNA analysis, human remains recovered near the Henry Hudson Bike Trail in Atlantic Highlands in 1988 have now been positively identified as belonging to Nancy. Though, precisely how and why she died still remains unknown.
