The burst of publicity did bring in some tips and recollections, but Schulze's disappearance remains a mystery.
Durst has declined to talk to Middlebury police, according to Chief Thomas Hanley, who said he believes the incarcerated man could provide information that would help resolve the case.
"We know that there was contact between them; we know that she went in there," Hanley said, referring to the health food store Durst owned in the '70s.
Locals may know more than they're saying, too.
"There are some people we suspect are somewhat reluctant to speak with us in depth," Hanley said, adding: "They may be holding a few things back."
