Overview
- Nancy Guthrie was last seen at her Tucson home on January 31 and authorities continue to treat the disappearance as a suspected kidnapping for ransom.
- Investigators have collected physical and digital evidence including blood on the porch and nearby street, doorbell footage of a masked person, pacemaker telemetry that stopped overnight, a single strand of hair, signs of forced entry, and human remains found near the property.
- The FBI Phoenix office said it has received several ransom-style communications and that some were ruled extortion while other demands "may potentially be legitimate" and remain under active investigation.
- A California man, Derrick Callella, pleaded guilty to sending fake ransom messages to the family, a prosecution officials say diverted resources and added to the family's distress.
- External experts have publicly criticized coordination and messaging between investigators and the Guthrie family, and authorities say forensic testing, blockchain tracing and tip collection continue with a family reward still offered.
