Although declared legally dead in 2001, the case was reopened in 2010. The F.B.I. are now currently digging up a Soho basement that Etan would have travelled past when he disappeared after cadaver-sniffing dogs believe that human remains may be present.
I think that there is guarded optimism that they're going to find something, an official said.
Etan disappeared 33 years ago. His disappearance sparked the milk carton campaign and also drew President Ronald Reagan to declare the day he disappeared National Missing Children Day.
We think it sends a message to searching families everywhere that just because it's been a month, or year or 10 years or even 33 years you never close the case until you learn with certainty what happened, Ernie Allen, President and Chief Executive of the National Center for Missing and Exploited Children told CNN.
