FILE - In this May 18, 1985 file photo, Stanly Patz, left, holds a photo of his son Etan, as he poses for a photo with his other son Ari, at their home in New York. Etan Patz vanished on May 25, 1979. One of the most extensive missing-child searches was mounted to find him but two decades later, the boy was officially declared dead. No one has ever been arrested. Now, the Manhattan district attorney's office will take a fresh look at the evidence collected against the prime suspect, a convicted child molester serving 20 years in prison in Pennsylvania.
