Today anchor Savannah Guthrie posted a series of videos Friday explaining how to collect the $1million reward her family is offering for information leading to the safe return of her mother, Nancy.
Guthrie, 54, reposted part of her original Instagram plea announcing the new reward Tuesday, reiterating that it is still on the table.
The NBC star also shared a Today show report explaining how to submit anonymous tips to the FBI, oversaw by co-anchors Carson Daly, Hoda Kotb, and Craig Melvin.
'Please - be the one that brings her home,' Guthrie wrote in a caption. 'Tips can be anonymous, reward can be paid in cash, as explained here.'
The Friday segment explained how citizens can call in tips anonymously. All that's required from informants is a 7-digit pin number and a 'neutral' site like a post office to collect the sum, the stars said.
Law enforcement officials have previously expressed concern that tips may be hard to secure due to would-be informants being fearful of their identity being compromised.
$1M Reward Offered in Desperate Search for 84-Year-Old
Nancy, 84, has been missing for 27 days and was last seen at her home in Tucson, Arizona late on the evening of January 31.
'Please bring her home. You can be anonymous,' Guthrie, 54, wrote in the caption for her other post, which contained the latter part of her Tuesday missive.
'We need to know where she is. We need her to come home. For that reason, we are offering a family reward of up to $1 million for any information that leads us to her recover,' Guthrie said.
She added: 'If you've been waiting and you haven't been sure, let this be your sign to please come forward.'
'Tell what you know and help us bring our beloved mom home so that we can either celebrate a glorious, miraculous homecoming or celebrate the beautiful, brave, noble and courageous life that she has lived. Please be the light in the dark.'
A different portion of the same video shared earlier this week saw the star acknowledge for the first time that the senior could be dead.
'We need to know where she is, we need her to come home. We also know that she may be lost, she may already be gone. She may have already gone home to the lord that she loves,' Guthrie said.
Agents were spotted outside Nancy's residence Wednesday as part of an FBI effort to turn the home back over to the Guthrie family, officials told NBC News.
Droplets of blood were previously found on the residence's front porch, and footage recovered from Nancy's Nest camera showed a suspect in a ski mask in front of her door early February 1, minutes before her pacemaker suddenly stopped transmitting.
No suspects have been named and no arrests made as of yet.
During their searches Wednesday, agents combed portions of the property that were already searched.
Sources told ABC News Thursday there was no more work to be done at the home so they were moving their command center to Phoenix, where Arizona's biggest FBI base is set.
At this stage, investigators are scrutinizing things such as security footage, DNA samples, and Walmart sales receipts - as well as more than 1,500 tips that have flooded in since Savannah said the family was now offering a $1 million reward on Tuesday.
Following a quick surge Tuesday, the number of calls to the sheriff's department has since dissipated, sources told the network.
