NYPD Commissioner Ray Kelly on Friday said an array of new technology unavailable to law enforcement in 1979 including x-rays and black lights are being used in the investigation.
The new probe is reexamining the decades-old assumption that Patz was abducted by convicted pedophile Jose Ramos. It has not ruled Ramos out, and Miller is not named as a suspect. Miller's lawyer, Michael Farkas, says his client is innocent and cooperating with authorities.
Some of the strongest evidence against Ramos, who has an extensive criminal history of molesting boys, came in what became known as "the 90 percent confession." It took place in the Southern District of New York office of Grabois, when he was investigating the case. Grabois and a detective listened as Ramos told them that the boy in the Etan Patz missing persons fliers resembled the boy he had taken home for sex the day before the disappearance.
"I'm 90 percent sure," he told Grabois, that the boy was the one he "took to my home for sex." He described several of his actions with Etan, but then asked for an attorney and later changed his story.
Farkas would not comment on whether sex crime allegations brought against Miller by an ex-wife several years after the Patz disappearance were part of the information presented to a judge by the Manhattan District Attorney's office in order to obtain a search warrant. The District Attorney's office has declined any comment on the case accept to acknowledge it reopened it in January 2010 and that the warrant was requested by that office.
On Saturday, the FBI said that work was progressing "slowly and methodically." Federal Agent Tim Flannelly, of the FBI New York field office said that no revelations were likely to be forthcoming over the weekend.
