Former FBI agent Jonny Grusing is proposing a new theory in the disappearance of Nancy Guthrie, suggesting the suspect may have targeted her due to a personal grievance. Grusing, who worked in the FBI's Denver Division for 25 years, believes the man seen on Guthrie's property was attempting to lure her out of her home, not conducting a random robbery.

Evidence supporting this theory includes blood spattered on Guthrie's front porch and a gun worn in what appears to be a cheap holster. Grusing points out the suspect's behavior—covering security cameras and attempting to shield himself—suggests he wanted to confront Guthrie directly rather than remain unseen during a burglary.

The Tucson resident has been missing since Saturday night, with investigators releasing photos of a "subject" on her property. FBI agents have canvassed nearby homes while awaiting DNA results. The $100k reward remains active as authorities continue to piece together what led to Guthrie's disappearance.
