Nancy Guthrie live updates: DNA from someone other than Guthrie was collected from her property

Video evidence, like from a doorbell camera, has become a crucial piece of investigations such as the one into Guthrie’s disappearance, said Jamie Siminoff, the chief inventor and founder of Ring doorbell cameras.

“I just think we’re seeing that video footage is the most important thing in solving these crimes,” he said, also pointing to how footage helped locate the Brown University shooter.

Siminoff said that although Guthrie’s house had a Nest camera, Ring is relevant in this case because others in the neighborhood may have had Ring cameras.

Investigators have asked community members to submit any video relevant to the Guthrie case, including footage from doorbell cameras that may show vehicles in the area around the time she went missing.

Siminoff explained how that works. Local police departments can send community alerts to neighbors via the Ring app, prompting them to upload video footage.

There is also a Neighbors app that people in the neighborhood use as a social media platform to discuss community happenings as well as crime and safety. Siminoff said police have also put a similar request out on that app.

“We’re seeing our systems used pretty heavily for this, as we’ve seen it in other serious cases,” he said.

In order to send Ring video to the police, those who get the alert can look through their footage, select relevant video clips, and upload them through the system. A digital audit trail makes it “super easy and efficient,” Siminoff said.
