In its latest plea, the Barron County Sheriff's Office on Thursday requested 100 volunteers to help officials search for evidence tied to a double-homicide and missing teen case.
But as of late Thursday afternoon: "nothing of evidentiary value has been recovered," the department said on its Facebook page.
The sheriff's office had earlier asked for only 100 able-bodied people to help "in conducting a routine search for articles of evidentiary value that may be related to" the disappearance of Jayme Closs, 13. Her parents, James and Denise Closs, were found shot to death early Monday morning in the family's home.
Jayme has been missing since that time.
Authorities said they have received more than 800 tips in the case since Monday.
The office asked for community members to watch its social media accounts. And if anyone had information about Jayme Closs' whereabouts to call its tip line at 1-855-744-3879.
Authorities say a missing Wisconsin girl's parents were shot to death and that they believe she was in the home at the time. Police have been searching for 13-year-old Jayme Closs since early Monday, when deputies responding to a 911 call from her home in Barron found her parents, James and Denise Closs, dead in the house.
Barron County Sheriff Chris Fitzgerald said at a news conference Wednesday that autopsies confirmed the couple was shot. He says there was no gun at the scene and that evidence from the scene and from the 911 call indicate that Jayme Closs was in the house.
Fitzgerald asked people to take time to look for the girl.
"Check your cabins, walk your land and report anything you feel is important to us. You will never know if it will help to bring Jayme home unless you call," Fitzgerald said.
Fitzgerald has said Jayme is not a suspect. He says investigators have not received any tips of any credible sightings.
