Nancy Guthrie latest: Task force awaits forensic results as search enters third week

Retired FBI Supervisory Agent James Gagliano highlighted the complexities in the process of getting potential forensic results from the home of Nancy Guthrie during an appearance on “FOX & Friends Weekend.”

Gagliano said that while it generally takes 48 hours to get forensic results, the actual timeline can vary depending on different factors.

“What has complicated this is that most of the evidence, if not all of the evidence to date, has gone down to that contracted private lab in Florida,” he said of the Guthrie case.

According to a report by KOLD, DNA Labs International, located in Deerfield Beach, Florida, is where Pima County Sheriff Chris Nanos has sent key evidence to be examined. State records confirm that Arizona has a contract with the company for “biological laboratory services” that began in 2022 and runs through March.

A federal law enforcement source previously told Fox News Digital that the evidence will need to be retested by the FBI.

“What complicates that is by the time the FBI gets that evidence and DNA it will have been degraded or diluted,” Gagliano said Sunday. “You have to use part of the sample in order to conduct those tests.”

Gagliano added that the FBI uses the Combined DNA Index System (CODIS), an electronic database of DNA profiles. Investigators can use DNA in this system to compare it with the DNA evidence collected from crime scenes.

In terms of when the forensic results, if any, will become available in the Guthrie case, Gagliano said it appears “it’s going to take a little bit of time.”
