When: May 25, 1979

The facts: A six-year-old boy in SoHo leaves to catch a school bus and, after turning around to wave to his mother, is never seen again. Every parent’s nightmare. The poster continues to haunt the city: STILL MISSING.

The fear: Throughout the city, throughout the nation, Etan Patz's face reminds parents that their children might not be safe. Then-President Reagan declares May 25th National Missing Children's Day.

22 years later: A judge declares Etan Patz dead in June of 2001 at the request of his parents who want to pursue a wrongful death lawsuit against Jose Antonio Ramos, the man they believe killed their child. Ramos is currently in jail for child molestation and has allegedly confessed to other inmates that he killed Patz.
