Nancy Guthrie’s kidnapping case remains a mystery with no significant breakthroughs. The case is gaining new attention due to evolving theories involving DNA evidence from the crime scene.
John Ramsey, father of JonBenet Ramsey whose murder remains unsolved, recently shared his thoughts on the ongoing investigation into Nancy Guthrie’s disappearance in an interview on May 20, 2026.
Ramsey warned against assuming the police are doing everything they can do and urged the family to scrutinize their actions. He specifically asked about the status of DNA evidence, suggesting that traditional methods like CODIS may be obsolete compared to modern investigative genetic genealogy (IGG).
“DNA—what’s the status of the DNA? Do you have DNA that doesn’t match anybody in the family? What are you doing with it? Just putting in CODIS—that’s obsolete. That’s not going to result.”
“That worked for 30 years ago, that’s all we had. But now you can employ IGG [investigative genetic genealogy], and create a family tree, and with pretty good probability, get a name on the killer.”
Nancy Guthrie has been missing from her Arizona home since February 1, 2026. Despite authorities believing she was abducted based on all collected evidence, no suspect has been named after 100 days of her disappearance.
