Overview
- Pima County’s Nancy Guthrie Task Force traveled to Florida earlier this month to meet lab scientists and discuss additional DNA and forensic techniques, the sheriff’s office said.
- Investigators say they continue active DNA testing with multiple state and federal labs contributing and that new testing approaches were discussed with outside experts.
- A bone fragment recovered in Oro Valley has been turned over to the Pima County medical examiner but officials have not linked it to Nancy Guthrie.
- No suspect or arrest has been publicly announced, and authorities continue to rely on the FBI video of an armed person at Guthrie’s front door as a key public clue.
- Officials urged anyone with information to report tips to local investigators or the FBI, and Savannah Guthrie and the FBI are offering private and public rewards to encourage leads.
