The search for Nancy Guthrie continues, with investigators focusing on ransom notes that may contain clues about her whereabouts.

Former FBI agents say differences in word choice, tone, and structure between the notes could help determine whether they were written by the same person or multiple individuals.

One note reportedly included specific details not publicly known at the time, while later messages shifted in language and emotional tone.

Experts suggest the wording may indicate either guilt, attempts to distance responsibility, or a desire for control by the abductor, News Nation has reported.

Guthrie was reported missing in early 2026 after her pacemaker stopped communicating with her phone, suggesting the timing of her disappearance.
