Nancy Guthrie Update: Ex-FBI Agent Says Investigators Are Closing in on 'Porch Guy' Suspect Five Months Later

A retired FBI agent says investigators may be closing in on the masked man caught on Nancy Guthrie's home security camera the night she disappeared, raising fresh questions about why no arrest has been made nearly five months into the case.

Nancy Guthrie, the 84-year-old mother of "Today" co-anchor Savannah Guthrie, went missing on February 1 from her home in the Catalina Foothills, a suburb of Tucson, Arizona. Investigators believe she was abducted overnight, and her case has remained one of the most closely watched missing-persons investigations in the country in the months since.

A retired agent's confident prediction

Speaking on SiriusXM's "The Megyn Kelly Show" Tuesday, retired FBI Special Agent Maureen O'Connell said she believes law enforcement is nearing a breakthrough in identifying the masked figure seen on Guthrie's doorbell camera footage. "I think they're close right now to pulling this case together," O'Connell said. "That's what my sources are telling me... Things are happening."

O'Connell went further when pressed for specifics, putting a number on her confidence level. Asked directly about the masked individual, she said, "I think they're getting close to the porch guy. And when they get the porch guy, the floodgates shall swing open."

The remarks visibly surprised the show's host. "What?!" Kelly responded, before asking O'Connell to elaborate on why she believed authorities were nearing an answer. When Kelly followed up by asking for her level of confidence, O'Connell put the figure at "75 percent."

Why the case has moved so........
