In the latest update in the disappearance of Nancy Guthrie, the 84-year-old mother of Today show co-host Savannah Guthrie, the FBI has released newly recovered doorbell footage showing an armed, masked subject on her Tucson porch.

How did investigators recover these "missing" images from the morning of the abduction? Matt Sailor, Founder and CEO of IC Realtime and ICRealTech joins us on Fox 10 Talks as a global leader in high-end video surveillance and patented immersive camera technology.
