Is Etan Patz the most famous missing child of all time?
As she was beginning her career as a photojournalist, Carrie Boretz shot thousands of images on the streets of New York City. One of those images, she realised years later, was of Etan Patz and his family.
Etan's face and name became famous in the worst way, after the little boy disappeared on the way to school on May 25, 1979. His body was never found and the day he vanished is now known as National Missing Children's Day.
Thirty six years years on the case continues to haunt those who remember.
