A former FBI agent has pointed to a damaged utility box near the Tucson-area home of 84-year-old Nancy Guthrie as potential evidence that her abduction on 31 January was carefully planned, with investigators now examining whether the device was deliberately tampered with to cut internet service in the neighbourhood before she was taken.
A Utility Box And A Question Of Planning
Jennifer Coffindaffer, a retired FBI special agent, drew fresh public attention to the investigation on Wednesday when she posted on X alongside a WTHR report examining the damaged utility box found near Guthrie's property.

So if a neighbor's ring stopped working at the time of the abduction, was there an accomplice that was going a round the neighborhood with a frequency jammer? Is that the premise?

'Did the perpetrators in Nancy's abduction tamper with a nearby electrical box?' Coffindaffer wrote. 'That makes sense and the FBI is investigating.'
"Apparently the notion of more than 1 perpetrator is also being intimated by LE. That also has always made sense", she added.
Investigators Probe Internet Outages And Damaged Utility Box
Detectives have been going door to door, asking residents in Guthrie's neighbourhood whether they experienced internet problems on the night she disappeared.
Some homeowners reported that their connections faltered, and, crucially, that their security cameras glitched during that same period.
A damaged utility box close to Guthrie's home has now been pulled into the inquiry. Law enforcement has not publicly confirmed that the utility box was tampered with, or that any internet glitches were caused by criminal acts.
Nancy Guthrie "Even More Vulnerable" To An Attack
During a 8 March episode of Brian Entin Investigates, retired FBI special agents Maureen O'Connell and Jim Clemente walked through what they believe could have made Nancy Guthrie a particularly attractive target for an abductor.
Clemente said he understood that Nancy suffered from hearing loss and used 'pretty powerful hearing aids' during the day. In his view, the fact she would likely have taken them out before going to bed could have made her significantly easier to overpower.
'I think she also had hearing issues and pretty powerful hearing aids that she probably removed at night,' he told the programme. 'Which makes her even more vulnerable.'
'I think also, the altercation, quote unquote, could have happened if she obviously had her hearing aids out, and they [the suspects] were giving her commands, and she could respond. Because she didn't know what they were saying,' O'Connell said.
'It's so sad,' she added.
The Surveillance Footage About the Nancy Guthrie Abduction
On 10 February, the FBI released doorbell camera footage showing a masked individual standing on Guthrie's porch on the night she vanished. The man was wearing a ski mask, long trousers, a jacket and gloves, and was carrying a 25-litre Ozark Trail Hiker Pack backpack while also bearing a handgun holster.
The FBI described him as approximately 5 feet 9 or 10 inches tall with an average build. The footage showed him covering the doorbell camera with a piece of brush before disabling it entirely.
Retired FBI agent Andrew Bringuel, reviewing the case separately, suggested the suspect appeared initially unfamiliar with the exact placement of the camera but noted the backpack was large enough to carry tools or specialist equipment, reinforcing the suspicion that this was no improvised act. Investigators believe the contents of that backpack may yet prove significant.
DNA has been collected from inside Guthrie's home, and a pair of black gloves was recovered approximately two miles from the property, though early testing indicated they may not be directly tied to the suspect. A reward of more than $1 million (£743,540) has been publicly offered for information leading to a resolution.
Now into its sixth week, the investigation continues to involve the FBI and the Pima County Sheriff's Department. As of early March, Sheriff Nanos told reporters that investigators were 'definitely closer' to identifying the suspect.
