(CNN) — More than 30 years ago, 6-year-old Etan Patz vanished from a Manhattan street on his way to a school bus stop. His parents never saw him again.
The case — lately reopened by police — riveted millions. It also changed the country.
“It awakened America,” said Ernie Allen, president and chief executive officer of the National Center for Missing & Exploited Children. “It was the beginning of a missing children’s movement.”
