NYPD Commissioner Ray Kelly on how a new lead and advanced technology could bring closure to 30-year-old Etan Patz case

All this morning, we've been reporting on a possible break in the disappearance of Etan Patz, a story that captured the nation's attention 33 years ago.

The six-year-old vanished without a trace from his home in New York City on May 25th, 1979, without a single shred of physical evidence. The case had gone cold.

But yesterday, an FBI dog picked up the trail of possible human remains just yards from where Patz lived.

This morning, Soledad talks with NYPD Commissioner Ray Kelly on "Starting Point" and asked him why there was a renewed focus on the case.
