Nancy Guthrie live updates: Officials not ruling out possibility that multiple people were involved

The FBI ran DNA from a glove found during a roadside search through the national database known as CODIS, and did not get a match to any of the roughly 22 million samples in the database, according to the Pima County Sheriff's Department.

That glove -- which was found about 2 miles from Nancy Guthrie's house -- also did not match DNA found at Guthrie's property, law enforcement sources told ABC News.

The DNA found at the property is being analyzed and further testing needs to be done on it, the sources said.

DNA from the glove recovered near Nancy Guthrie's home remains at a private lab in Florida, where the Pima County Sheriff's Department sent it on Feb. 12, law enforcement sources told ABC News.

The sample is still undergoing quality control tests before the FBI hopes to run it through CoDIS in the "near future," the sources said.

Pima County Sheriff Chris Nanos said Monday that members of the Guthrie family are "cleared" as suspects in Nancy Guthrie's disappearance.

"To be clear ... the Guthrie family -- to include all siblings and spouses -- has been cleared as possible suspects in this case," the sheriff said in a statement. "The family has been nothing but cooperative and gracious and are victims in this case."

"The Guthrie family are victims plain and simple," the statement said.

ABC News previously reported that, according to law enforcement sources, investigators were leaning away from the Guthries as suspects.

The Pima County Sheriff's Department said it's possible the suspect in Nancy Guthrie's kidnapping may have purchased the clothes he's seen wearing on the surveillance camera at Walmart, but that clothing is not exclusively available at Walmart.

Investigators last week were working to trace the point of sale of the suspect's backpack, which was sold at Walmart.

Meanwhile, the FBI is focused on the unknown male DNA from a glove found about 2 miles from Nancy Guthrie's home.

The FBI said it received preliminary results on Saturday. The FBI said on Sunday it was "awaiting quality control and official confirmation" before putting unknown male profile into the Combined DNA Index System, the national database known as CODIS.

The glove with the DNA profile "appears to match the gloves of the subject in the surveillance video," the FBI said.
