Dozens of investigators searching for 13-year-old Jayme Closs met Friday in Barron, Wis., to review more than 2,300 tips and other leads that they've tracked since Oct. 15, when her parents were shot to death in their home and she disappeared without a trace.
"This is somewhat of a head-scratcher. That's why we're coming back at it," Barron County Sheriff Chris Fitzgerald said Friday during an interview on the online news program at DrydenWire.com.
Despite the large number of investigators from his department, the Wisconsin Division of Criminal Investigation and the FBI, Fitzgerald said, they still have "no working theory" of what happened inside the Closs family home on the outskirts of Barron that night.
He said the public interest in the case has been overwhelming.
"We've had sightings all over the United States," Fitzgerald said, adding that investigators check out each one, most within an hour or so.
He encouraged people to keep forwarding tips despite the fact that checking them out can be time-consuming, but he asked tipsters to try to be specific.
"Saying that Jayme is in a barn in Wisconsin isn't helping us," he said, noting the large number of barns in the state.
The sheriff said that deputies arrived at Jayme's house within 4 minutes of the end of a 911 call from the residence early in the morning of Oct. 15. Inside, they found Denise Closs, 46, and James Closs, 56, dead from gunshot wounds, but found no suspects or gun and no sign of Jayme, who was ruled out as a suspect early on.
