Overview
- The Pima County Sheriff’s Department and FBI say several hundred personnel are reviewing thousands of tips with no publicly identified suspect or verified proof of life.
- DNA from a glove found about two miles from the home created a profile but returned no CODIS match, and additional biological material from the residence is undergoing analysis with genetic genealogy under consideration.
- Investigators are working with Google to retrieve Nest camera data and have tried detecting Guthrie’s pacemaker signal from low‑flying helicopters, while a Walmart‑sold Ozark Trail backpack seen on the suspect is being traced.
- Reports indicate U.S. authorities have communicated with counterparts in Mexico, though Sonora’s attorney general says no formal request has been received, and the sheriff reports no evidence Guthrie was taken across the border.
- Combined rewards now exceed $200,000 through FBI and 88‑CRIME offerings, and media continue to forward unverified ransom emails to investigators as one person has been charged over a fake threat.
