At this time:

No major law enforcement agency has publicly confirmed releasing such footage.
No official statement indicates a “critical moment” captured on Nest cam being circulated to the public.

There is no verified nationwide FBI bulletin tied to this specific scenario.
When authorities release surveillance images in an active missing-person case, they typically:

Issue a formal press release.
Publish images through official agency websites or verified social media accounts.
Distribute information to major news outlets simultaneously.
If a post uses urgent language like:

“Time running out”
“Awareness now could save her life”
“Report ANY recognition immediately”
…but does not link to an official law enforcement source, it may be amplifying unverified or fabricated material.

Important Reminder
Sharing unconfirmed suspect imagery can:

Spread misinformation
Wrongly identify innocent individuals
Complicate active investigations
If you’re trying to confirm whether this appeal is real, the safest approach is to:

Check official FBI or local police department websites
Review verified news outlets
Look for direct statements from law enforcement spokespersons
