Big picture view:

The billboard rollout comes the same day the FBI released surveillance video from outside Guthrie’s home that appears to show a masked individual tampering with the front door camera early Sunday morning, Feb. 1. 

At the same time, authorities confirmed a person of interest was questioned in connection with the case. That person was later released.

Investigators are asking the public to review the FBI-released surveillance video closely and report any information that could help identify the masked person.

‘Does a billboard help?'

What they're saying:

FOX 26 spoke with Tim Miller, with Texas EquuSearch — a private search expert who is not involved in the investigation — who says billboards may not answer every question, but can be a tool to keep the case visible and trigger the right tip.

Miller says awareness campaigns can bring in valuable information — even if investigators have to sort through a high volume of calls.

"Does a billboard help? I don’t know. Does it hurt? I don’t think it hurts. I mean, it only takes that one call, and I’m sure that they’re getting thousands of calls and different things coming in," Miller told FOX 26.

Clear Channel Outdoor says it is donating digital billboard space to help keep the case visible. In a statement to FOX 26, the company said, "Our hearts and thoughts are with the family and friends of Nancy Guthrie, and we hope for her safe return. We are cooperating and supporting law enforcement in their search for Nancy Guthrie by donating space on our digital billboards, which are live now, and broadcasting her image across Houston and other surrounding areas in our footprint."
