Overview
- Nancy Guthrie, 84, vanished from her Catalina Foothills home on Feb. 1 after security footage showed a masked person at the property and blood later tested to belong to her.
- Investigators have sent mixed DNA and digital evidence to the FBI laboratory in Quantico and to a private Florida lab, and officials say careful testing is needed to preserve results for court.
- No suspects or arrests have been publicly announced as labs continue analysis and detectives review thousands of public tips and leads.
- Savannah Guthrie has renewed public appeals on social media and on Today, and the family’s reward offer has grown to more than $1.2 million to encourage tips.
- The probe is accompanied by a public dispute over the early timeline of FBI involvement and a separate federal charge against a California man accused of sending a fake ransom note to the family.
