Overview
- Investigators with the Pima County Sheriff’s Office and the FBI say the case remains active with no named suspect, citing ongoing DNA testing and broad reviews of neighborhood video.
- Genetic genealogist CeCe Moore urged a fresh search of Guthrie’s home for saliva on a flashlight seen held in the suspect’s mouth on doorbell video, calling it a hardy source of usable DNA.
- Sheriff Chris Nanos said some DNA from the scene may still be workable, following earlier findings that included blood on the porch and a 2:30 a.m. disconnect of Guthrie’s Bluetooth pacemaker.
- Media outlets have received ransom messages, including new cryptocurrency demands and a claim of a sighting in Mexico, but authorities have not verified any of them and say they are under review.
- Expert views diverge on motive, with criminal profiler Ann Burgess pointing to possible personal retribution and former FBI agent Jennifer Coffindaffer arguing it was a ransom plot and asserting—without confirmation—that Guthrie died.
