A forensic laboratory in San Francisco, instrumental in solving the Long Island serial killer case, is now reportedly aiding the investigation into the suspected kidnapping of Nancy Guthrie in Tucson, Arizona.<\/p>\n

Rex Heuermann, known as the Gilgo Beach killer, confessed to the murders of eight women between 1993 and 2010. Earlier this month, he pleaded guilty after his defense was unable to refute the revolutionary DNA evidence derived from rootless hair samples.<\/p>\n

\u201cI am quite confident they will choose to work with Astrea, given its past successes,\u201d stated CeCe Moore, a prominent genetic genealogist with Parabon Nanolabs in Virginia. \u201cDNA Labs International has been trying to perfect rootless hair analysis, but I haven\u2019t seen any successful outcomes from them yet.\u201d<\/p>\n

Moore\u2019s comments pertained to DNA Labs International, the Florida-based laboratory initially entrusted with analyzing samples by the Pima County Sheriff\u2019s Department following Guthrie\u2019s alleged abduction.<\/p>\n

Now that the FBI has the materials, Astrea Forensics could be on the shortlist of specialized private labs that could help.<\/p>\n

The lab developed a DNA profile from rootless hair evidence in the Heuermann case, and Moore said she\u2019s personally been involved in six successful cases in which Astrea did similar work.<\/p>\n

\u201cThe FBI used them for the Gilgo case,\u201d she told Fox News Digital. \u201cSo they have a lot of confidence in Astrea.\u201d<\/p>\n

An FBI official told Fox News Digital on Thursday that among the evidence collected from inside Guthrie\u2019s home is a hair sample that had been sent to a private lab in Florida by the Pima County Sheriff\u2019s Department in the days after her suspected kidnapping.<\/p>\n

\u201cIf there\u2019s a chance they can solve Nancy\u2019s case\u00a0through this lab, I believe without question it should be sent there,\u201d said Allison Winter, a social worker and psychotherapist who has been working with the Heuermann family.<\/p>\n

Now, with no answers more than 11 weeks later, the sample has been sent to the FBI for more advanced testing.<\/p>\n

\u201cSending it to Astrea, where there is a proven track record, is by far the safest option,\u201d Moore told Fox News Digital.<\/p>\n

The FBI had wanted the sample more than two months ago, according to Ben Williamson, who is assistant director of public affairs at the FBI.<\/p>\n

\u201cThis is not new evidence or information,\u201d he wrote on X Monday. \u201cFBI asked to test this DNA 2 months ago with the same technology we\u2019ve always had \u2014 when the local sheriff instead sent it to a private lab. Any further developments we will share as soon as appropriate.\u201d<\/p>\n

Fox News Digital reached out to Astrea but did not immediately receive a response.<\/p>\n

Anyone with information on Guthrie\u2019s disappearance is asked to call 1-800-CALL-FBI.<\/p>\n

There is a combined reward of more than $1.2 million for information in the case.<\/p>\n
