SAVANNAH GUTHRIE'S MOM MISSING: DAY 19

New DNA was discovered inside Nancy Guthrie's home two weeks after the initial investigation and after the home was returned to the family. This significant delay and the potential for multiple people (including reporters and family) to have entered the scene raise serious concerns about contamination, which could be exploited by defense attorneys in court, similar to the OJ Simpson case.

Dave Matt reports 'new DNA inside the house not found before' (01:33). Nema Romani states, 'you have DNA found later' and mentions 'contamination of the crime scene' (03:30). Tom Smith notes '50 people have been trampling through that crime scene' (05:33).

Investigators are exploring novel digital tracking methods beyond cell phones. This includes using data from vehicle connectivity services like SiriusXM, UConnect, and OnStar, which rely on cellular networks and can be geo-fenced. Furthermore, any Wi-Fi enabled device, such as iPads or smartwatches, can be detected within a geo-fenced area by its signal, even if it doesn't actively connect to a network, providing additional location data.

Scott Aker explains that SiriusXM, OnStar, and UConnect connect to the cellular network, allowing investigators to 'look at the cellular data for that vehicle' (12:12). He adds that Google can determine devices in an area 'based on their devices, Android phones getting signal from the various Wi-Fi points' (15:22), including iPads, watches, and cars (16:33).

The theory of an accomplice is gaining traction due to video evidence showing the perpetrator with and without a backpack, suggesting it was handed off or retrieved from a waiting vehicle. Additionally, Nancy Guthrie's age (84) and reported mobility issues (unable to walk 50 feet unaided) make it highly improbable for a single individual to abduct her, especially if she became 'dead weight.'

Dave Mack points out the perp is seen 'with a backpack and... without a backpack' (18:04). He argues, 'to walk somebody who has issues walking is not an easy feat. To get her out of that house would have taken two people' (21:54). Tom Smith agrees, 'Kidnappings are usually never done by one person' (25:32) and 'even remotely resisting is very, very difficult for one person' (25:52).

The Pima County Sheriff's Department, led by Sheriff Nanos, is featured in an A&E reality show called 'Desert Law.' Legal experts warn that this involvement could be used by defense attorneys to cross-examine law enforcement witnesses on potential 'pecuniary or money interest' in the case's outcome, even if no direct financial link exists. This could undermine the credibility of evidence and testimony.

Dana Bowling reveals 'Desert Law' (32:41) and quotes Sheriff Nanos expressing surprise at media attention despite signing up for the show (33:13). Nancy Grace argues 'any witness can be cross-examined on a potential pecuniary or money interest' (35:54). Tom Smith states, 'a reality show is just making it worse' (38:27) and 'when Nanos takes a stand, he will be cross-examined on a pecuniary or money interest' (38:53).

The Guthrie family has taken the initiative to contact 'the searching mothers of Sonora,' a group in Mexico that helps find missing people. This action comes amidst reports from Mexican authorities that no formal FBI request has been made regarding Nancy Guthrie's case, despite the close proximity of Sonora, Arizona, to Sonora, Mexico, and the ease of crossing the border.

Dave Mack reports, 'The Guthrie family has reached out to the... searching mothers of Sonora' (29:41) and 'not by the FBI, not by the sheriff's department' (29:53). He adds, 'Mexican authorities say no formal FBI request has made been made in the Guthrie case' (30:54).

An unidentified individual in Tucson conducted an internet search for Nancy Guthrie's address and Savannah Guthrie's income approximately six months before the kidnapping. This digital footprint suggests a pre-meditated plan and specific targeting of the victim, providing a crucial lead for investigators to trace back to an IP address or subscriber account.

Dave Mack states, 'we have an unidentified individual in Tucson who actually did an internet search looking for two specific things. One, Nancy Guthri's address in Tucson, and the other, Savannah Guthri's income' (44:16). Scott Aker confirms, 'Google searches of who might have searched those addresses led us to an IP address or a subscriber account' (45:17).
