Nancy Guthrie Update: Lab in Serial Killer Conviction Reportedly Involved in Savannah's Mom's Case
Today co-anchor Savannah Guthrie's mom, Nancy Guthrie, 84, is still missing after her Feb. 1 abduction in Tucson, Ariz. However, a lab that helped in the conviction of Long Island serial killer Rex Heuermann is now reportedly involved in the case.
On April 21, genetic genealogist CeCe Moore weighed in on the FBI recently receiving DNA evidence from Nancy's home, after the Pima County Sheriff's Department first sent it to a Florida lab.
That hair sample, Moore speculated, is likely at the San Francisco forensics lab that helped solve the Long Island killer's case earlier in April. Heuermann pleaded guilty to killing eight women in the Gilgo Beach area between 1993 and 2010 thanks to DNA evidence retrieved from rootless hair samples.
"I am pretty confident that they will want to use the lab that they have been extremely successful with, which is Astrea," Moore told Fox News Digital. "DLI has been working to refine their own rootless hair analysis, but I haven't seen any successful cases from them yet."
She added, "The FBI used them for the Gilgo case. So they have a lot of confidence in Astrea... Sending it to Astrea, where there is a proven track record, is by far the safest option."

During a separate interview with NewsNation on April 19, Moore offered insight into the DNA analysis timeline.
"It can take months," she admitted. "In my experience with them, I've already helped law enforcement solve six cases using rootless hair alone. And so, I know it can be done. My guess is that because this is not a cold case yet, and most of the cases are where we're using rootless hair, that they will push this to the top of the priority list and get it done more quickly."
Nancy was last seen at her home on the evening of Jan. 31, with her family reporting her missing on Feb. 1. As of writing, no suspect has been named.
