EXCLUSIVE: Scene of Nancy Guthrie private lab testing. I’m outside DNA Labs International where the DNA Testing of evidence is happening right now.
I traveled to Deerfield Beach, Florida where lab technicians have been testing critical evidence in the investigation — including the glove found nearly 2 miles from her home.
We’ve heard a lot about the discrepancies of sending this type of DNA evidence to a private lab versus a lab used by the FBI, but the Pima County Sheriff, Chris Nanos, says this is their protocol, and a lab that they have used for years.
There are only a limited number of private accredited DNA labs in the country capable of this level of forensic work. If possible, DNA Labs International will develop a DNA profile from the glove.
According to independent DNA consultant Suzanna Ryan of Ryan Forensic, which is not connected to this case but can speak about how this all works, once a profile is developed it will most likely be sent to the Arizona Department of Public Safety.
That’s where the quality control process begins:
•A qualified DNA analyst or CODIS administrator verifies the data
•The profile must meet strict standards before upload
•Once approved, it is electronically transmitted through state systems to the Federal Bureau of Investigation
•All systems work together within the national DNA database network CODIS
This extra verification step can take time — but it’s critical to ensure the data is admissible and accurate.
In this exclusive video, I take you to the scene of where this testing is being done. Because the lab sits on private property, we were asked to leave by property management — but this is where the forensic work is happening.
