…That prompted speculation about the so-called
Wi-Fi jammers, which are illegal in the United States under Federal Communications Commission guidelines.
They're
not particularly high-tech. And they can be obtained online — which is potentially something investigators could track.
But the fact that
the FBI and Google were able to recover video from Guthrie's
Nest doorbell camera, when the device was physically missing, and she did not have a cloud subscription,
indicates a Wi-Fi jammer may not have been deployed at her front door.
"If they were using Wi-Fi jammers, then I would expect that we
would not be able to see any video from the front-door cameras," said Morgan Wright, the CEO and founder of the National Center for Open and Unsolved Cases. "I took a look at some of the videos with the other gangs that use Wi-Fi jammers, and had one been up and running and persistent,
you wouldn’t have gotten the clear pictures that we did from the front."
