CATALINA, AZ — In a complex update to the case that has gripped the nation, investigators are threading a needle between clearing family members of suspicion and maintaining a focus on their movements. Annie Guthrie (sister of NBC’s Savannah Guthrie) and her husband Tommaso were the last to see Nancy on January 31, having dropped her off after dinner. While PCSD has called social media rumors against them “cruel,” the forensic loop remains open.
1. The Vehicle Investigation
On Wednesday, CBS 5 reporter Briana Whitney broke the news that the car used on the night of the disappearance is still being processed.
- PCSD Stance: “The vehicle is still part of the investigation,” an official confirmed, though they declined to state if any new forensic markers or GPS data had been recovered.
- The Night of Jan 31: Investigators are reportedly verifying the exact timeline of the vehicle’s arrival and departure from Nancy’s Catalina home against neighboring surveillance footage.
2. FBI Returns to the Scene
After a two-week lull in visible activity at the residence, federal agents returned in force on Wednesday afternoon.
- Backyard Focus: Witnesses and local news (Fox 10) reported agents spending several hours in the backyard and pool area.
- Evidence Collection: Agents were seen wearing blue gloves and carrying equipment, sparking speculation that the search has moved from “recovery” to “minute forensic collection.”
- Genetic Genealogy: This follows the FBI’s Sunday announcement that DNA found on a black glove near the home is now undergoing genetic genealogy testing—a process that uses family trees to find a match when criminal databases fail.
3. Lockdown in Catalina: Media Restrictions
The surge in “true crime” tourism and aggressive social media streamers has forced the Pima County Department of Transportation to act.
- No-Parking Zones: Strict parking restrictions are now in place around the Guthrie home to “relieve area residents from chaotic conditions.”
- Public Safety: PCSD noted that the massive media presence was hindering the movement of emergency vehicles and potential investigative teams.
