Pima County Union Chief Says Inexperienced Team and Leadership Choices Hampered Nancy Guthrie Probe

His allegations point to early staffing and coordination failures that could have hindered preservation of doorbell footage, limited public outreach, strained relations with the FBI.

Overview

  • On Saturday, Aug. 15, Pima County Deputies Organization president Aaron Cross publicly accused county leadership of assigning largely inexperienced detectives to the Guthrie investigation and blamed those decisions on Sheriff Chris Nanos.
  • Cross says many investigators on the early team had about three years of experience and that the lead detective had no prior homicide work after a rapid promotion in 2023, which he argued left the unit underprepared for a major missing-persons probe.
  • He described weak internal communication, poor tracking of interviews that produced duplicate work, and what he called a premature release of the original crime scene, which he said was a major misstep.
  • Cross credited the FBI with recovering key Ring camera footage but also reiterated that local-FBI tensions and disputed timing over the bureau’s formal entry may have affected access to other time-sensitive Nest footage.
  • The case remains an active joint FBI–Pima investigation with no public suspect; it has drawn tens of thousands of tips, reward money exceeding $1.2 million, and growing scrutiny that could prompt reviews of evidence-preservation and public-outreach practices.
