Overview
- Authorities say the one‑month‑old investigation remains active, with the Pima County Sheriff’s Department refocusing resources to dedicated detectives and maintaining a patrol presence near the home.
- FBI personnel moved portions of the operation to Phoenix to process thousands of hours of surveillance, largely traffic‑camera footage, while a smaller contingent remains on the ground in Tucson.
- Forensic testing continues on mixed and low‑level DNA from the scene and a recovered glove that produced no CODIS match, and investigators are considering investigative genetic genealogy as labs work through the samples.
- Investigators are prioritizing digital leads, including CAST cell‑tower analysis to spot outlier devices and broad video reviews that include nearby Ring footage; no suspects have been publicly identified and Guthrie’s family has been cleared.
- Rewards total up to $1.1 million and tips have surged, while CNN reports two ransom notes were treated as credible but unverified, and experts emphasize the case is not considered cold.
