Drop Dead Serious with Ashleigh Banfield

Episode: Are Police Keeping Evidence They Shouldn't? | Nancy Guthrie Missing Day 27
Date: February 28, 2026
Host: Ashleigh Banfield
Guest: Chris McDonough (Director of Law Enforcement Relations, Cold Case Foundation; Former homicide detective; Host, The Interview Room)

Episode Overview

This episode marks the 27th day since Nancy Guthrie’s disappearance in the Catalina Foothills and centers on the concern over progress in the investigation, law enforcement’s shifting approach, and evidence handling. Ashleigh Banfield provides a candid and at times frustrated update on what little is known, noting the lack of major developments, possible law enforcement reallocation, and the impact of media access being restricted.

The in-depth interview with Chris McDonough provides expert insight into cold case definitions, the use of investigative technology, the roles of different law enforcement agencies, and speculation about why evidence (especially the impounded family car) is being handled in certain ways.

Key Discussion Points and Insights

Public & Media Frustration with Investigation Progress

• State of the Case: 27 days with “nothing to go on”—no suspects, no car, no clear leads. Banfield expresses frustration and worry over the lack of actionable information available to the public and the crowdsourcing community.

  • "We are heading into the weekend that will take us to one month and I really cannot believe that we are at one month with, honest to God, nothing to go on." (02:24)

• Crowdsourcing Value: Banfield emphasizes the value of public tips and social media ("many eyes are really valuable"), using the Gabby Petito case as an example.

  • "Just ask the Petitos. Gabby Petito was found because of YouTubers... the crowdsourcing that all of us as a community can do is really remarkable." (04:15)

• Law Enforcement Media Access: Recent restrictions on media access (parking outside the community, less visibility of law enforcement activity) raise concerns about transparency.

  • (21:47) Banfield describes this as both “a blessing and a curse” for neighbors and for the prospects of solving the case.

Recent Developments in the Guthrie Case

• Security Changes & Activity:

  • New security cameras installed at both Nancy’s and Annie’s homes.
  • Law enforcement and handymen seen at the homes, with heightened activity in the area (07:42).

• Video Evidence:

  • Crucial Car Video: Neighbor 2.5 miles from Guthrie’s house reported 12 cars passing between midnight and 6 am; one vehicle sped by at 2:36 am, eight minutes after Nancy’s pacemaker signal severed in her home (09:07).
    • TMZ claims the FBI has already dismissed this lead (10:21). Banfield is skeptical of how fast it was dismissed and says, “I just wondered how long it would take the FBI to dismiss that car. Right?”
  • Sheer Video Volume: Over 5,000–10,000 hours of surveillance footage have been collected for review (12:05).

• Resource Reallocation and Case Status:

  • Pima County Sheriff’s Department states the case remains active until all leads are exhausted, but is refocusing resources to detectives specifically assigned to the case.
    • "That makes me nervous when I see a change. You know, earlier this week, the FBI said they're going to be moving their operations up to Phoenix headquarters... it just makes me nervous..." (15:57)
  • Banfield notes this as possible “drawdown” in active investigation although the department says they will adjust as leads develop.

Understanding 'Cold Case' — Expert Perspective (w. Chris McDonough, 23:59)

• Definition: The case is not cold—the threshold is when all leads have been exhausted and the investigative phone line goes silent.

  • "At some point, your agency is going to say, you need to suspend that case because there's nothing happening... then that's when the case becomes cold..." (30:01, Chris McDonough)

• Current Status: Far from cold; there are thousands of leads and thousands of hours of surveillance to review.

  • "There are two lanes going here. One from Pima County Sheriff's Office, and... federal authorities are running down their leads." (23:59, McDonough)

Investigative Technology & Video Review (24:40)

• Advanced Tools:
  • Agencies, especially the FBI, utilize specialized software (e.g., Briefcam, flock cameras) to quickly scan surveillance for anomalies like specific vehicle types, colors, or license plates.
    • "There's a system called 'Briefcam'... those are the kind of systems that are available... the FBI to run the cars and all that video through." (24:40, McDonough)
  • AI can filter footage, but human investigators still must review all candidate video for context.
  • Flock cameras offer license plate reader capability, but some are reportedly not working or not designed for high-quality recording (27:27).

Interagency Collaboration & Resource Shifts (31:21)

• Reallocation Explained:

  • The FBI brings digital muscle and manpower, but as time passes, Pima County draws down their personnel, with the FBI leading digital analysis.
  • "Our resources, I.E. Pima county, we're going to kind of pull those back. We're going to still keep investigators moving this way... and we're going to let the FBI take a more productive role in trying to narrow down some of the... massive amounts of data..." (31:21, McDonough)

• “War Room” Approach:

  • FBI and Sheriff's office working together on the ground; leadership messaging sometimes causes public confusion about cooperation (34:00).

Key Evidence and Case Mysteries

The 2:36 am Car (35:04)

• Dead End or Not?:

  • Only TMZ (unconfirmed) reports FBI considers video a dead end already—possible if identification/alibi was quickly established via cellular analysis.
    • "They may have identified that driver already... they may have felt comfortable... this person's not involved. They admitted they were there. This is what they were doing." (39:06, McDonough)

• Cellular Analysis (CAST Team): FBI likely checks for phones present/moving at that time, runs 'geofence' analysis, and can cross-reference with video (40:08).

• Speculation on Suspect Tools: Discussion about whether a suspicious object in the suspect's pocket might be a Wi-Fi jammer, lock pick, or phone—if a jammer, would suggest sophistication, which would narrow suspect profile (42:59).

Evidence Handling — The Impounded Family Car (58:35 onward)

• Why Hold the Car?:

  • The daughter’s car remains impounded under warrant. McDonough says family cars don’t stay impounded unless there’s real evidentiary value.
  • "You do not impound family members' cars for no reason and not give them back... unless there's an evidentiary value. And that's where it becomes a piece of evidence." (58:42, McDonough)

• Legal Logistics: If there’s nothing incriminating, the family can request the judge release the car.

  • "The moment you come to this realization that there's nothing here, then you have to clear them. And part of that means give back what you took." (65:00, McDonough)
  • Might also be held to avoid losing potential defense evidence for future suspects, as in other high-profile cases.

Point of Entry and Investigation Transparency

• Sheriff’s Communications: Lack of clarity about the point of entry (back door, front, garage, etc.) and timeline when the family found Nancy missing has fueled rampant speculation and confusion.
  • "What was the point of entry into that house? And he's kept that under his hat." (48:55, Banfield)
  • McDonough argues that overly withholding these details from the public, while sometimes necessary, has contributed to media and public angst. (45:51, 52:36)

Was Nancy Taken From Her Bed?

• Both the sheriff and Savannah Guthrie herself described Nancy as being taken from her bed, although the sheriff “walked back” his earlier use of that term. If true, it suggests a targeted act and influences risk assessment.
  • "If she's literally taken from her bed and she wears powerful hearing aids... this really changes the potential of what this crime was." (65:57, Banfield)

Notable Quotes & Memorable Moments

• The Power of Media:

  • “Elizabeth Smart is a great example. You know, once the media goes away, the attention to the case goes away, the tips go away, and the case cools off, and one day could go cold. That’s something you don’t want.” — Ashleigh Banfield (21:54)

• On Defining a Cold Case:

  • “When an investigator is sitting at their desk and the phone’s not ringing, you have no tips. You have nothing going on. At some point, your agency is going to say, you need to suspend that case because there’s nothing happening.” — Chris McDonough (30:01)

• Advanced Investigative Technologies:

  • “Those are the kind of systems that are available to the, you know, the FBI to run the cars and all that video through.” — Chris McDonough, on AI video review tools (24:40)

• On the Impounded Car:

  • “You do not impound family members’ cars for no reason and not give them back. You don’t just hold it. The laws don’t get... The law does not allow you to do that unless there’s an evidentiary value.” — Chris McDonough (58:42)

• On Transparency:

  • “It just seems so quick, Chris, like it just surfaced yesterday in the evening and already by, you know, not even 24 hours later, dead end... do you think they can run down...that could happen in 24 hours?” — Ashleigh Banfield (39:55)

• Expert Optimism:

  • “I have a lot of optimism that there’s a lot going on behind the scenes... this case will be solved. I believe that.” — Chris McDonough (72:20)

Useful for Listeners Who Haven’t Heard the Episode

If you haven’t listened, this episode delivers:

• A frank state-of-the-investigation, emphasizing just how little substantial public information has emerged.
• Expert academic and practical guidance on what it means for a case to go cold—not just in jargon but in procedural reality.
• In-depth insight into investigative technology, interagency strategy, and how law enforcement balances possible evidence with public communication.
• Nuanced discussion about why investigators might keep evidence, and the dilemmas about clearing suspects or not.
• Emphasis on the power of media/public involvement, and open concern that restricting coverage may inadvertently imperil the case.

Conclusion:

As the one-month mark in Nancy Guthrie’s disappearance approaches, both public anxiety and scrutiny of law enforcement tactics grow. Banfield and McDonough together illustrate the complex, methodical, and sometimes opaque nature of an evolving major case — and stress patience, the value of continued crowd and media engagement, and the high likelihood that developments may still come, even when the public sees little movement.
