SNIP/ Police want to quiz man in teen's abduction
Earlier Wednesday, Salt Lake City Police Chief Rick Dinse expressed confidence that authorities will track down Smart's abductor no matter how long it takes.
"I can't set a time limit on this," Dinse said on CNN's "American Morning." "It may be soon. It might be later. It may be for quite a while."
Dinse reiterated an assertion he made Tuesday that police may have talked to the suspect.
"We believe we have enough information about the suspect, the characteristics of the suspect based on the crime scene, based on all of the investigative leads we've [had] up till now -- including a behavioral science picture of him," he said.
"We have narrowed our focus in order to meet those things that we believe will bring us to him."
Elizabeth Smart Police are zeroing in on the girl's upscale Federal Heights neighborhood, which Dinse said he believes the abductor has "had access to" for some time.
Investigators have spoken with contractors and real estate agents in the area. The Smarts' seven-bedroom, six-bathroom house is for sale for more than $1 million.
"We've looked at it [the neighborhood] originally and quickly in order to try to see if we could locate Elizabeth in a fast manner," Dinse said.
"After looking at everything and all of the leads that we have brought or have had, we think that this is the right way to go about trying to locate this person and bring Elizabeth back."
He said police have had more than 6,000 leads in the case and have identified 600 that are worthy of following up. He said police have talked to 300 people "and probably more than that" to date.
"There is a good chance in all of the people that we've talked to that we have, in fact, talked to the suspect," Dinse said. "Now we're going to focus in and go back to some of those people and, of course, continue investigating and interviewing new people." SNIP
