The neighbor of Nancy Guthrie recalled seeing a suspicious white van on their street before the 84-year-old grandmother disappeared from Arizona.
Brett McIntire, 72, reported the vehicle to police after noticing it didn't have any company branding on it like normal work vehicles, he told the New York Post.
'It was a white van, full-sized, with no printing on the sides. It was parked on the street,' he said.
Police reportedly asked him basic questions about the vehicle, which he had seen a few days before Guthrie's disappearance.
But the experience shook McIntire, who now keeps a paper and pen on him during his neighborhood walks, so he can report anything suspicious he might come across, he told The Post.
It also spooked his wife Lisa, who is now considering buying security cameras for their home, despite having heavy metal doors.
'I'm kind of a deep sleeper,' she told The Post, despite acknowledging that they have a 'pretty secure residence.'
'It's unlikely someone could get past one of the metal doors, but we're a little concerned,' she said.
Nancy Guthrie's neighbor said he saw a suspicious white van on their street days before his neighbor disappeared. Guthrie, the mother of Today Show host Savannah Guthrie, has been missing since Sunday.
Guthrie, who is the mother to Today Show host Savannah Guthrie, vanished from her $1million home in Tucson last weekend.
Authorities think she was taken against her will as her doorbell camera was disconnected around 2am on Sunday.
Software data recorded movement at the home at 2.12am, which police acknowledge could have come from a person or animal.
Guthrie did not have an active subscription with the doorbell app, so the company was unable to recover any footage.
Then at 2.28am, the app on Guthrie's pacemaker was disconnected from her phone.
Guthrie was reported missing shortly before noon Sunday after she didn't show up at a church.
While she is able to drive and her mind is sharp, the Pima County sheriff said she has difficulty walking even short distances.
She requires daily medicine vital to her health, has high blood pressure, a pacemaker and heart issues, police have said.
It is now six days into the desperate search for the grandmother, but authorities have not identified any suspects or persons of interest.
Police believe she was abducted from her home after her doorbell camera was turned off and her pacemaker was disconnected from her phone.
DNA tests showed blood found on Guthrie's front porch was a match to her, Pima County Sheriff Chris Nanos said.
'Right now, we believe Nancy is still out there. We want her home,' Nanos said at a news conference earlier Thursday.
He acknowledged, however, that authorities have no evidence she is unharmed.
Law enforcement are bringing more resources and people into the investigation, and the FBI announced Thursday it was offering up to $50,000 for information.
President Donald Trump said he has spoken with Savannah and posted on social media that he was directing federal authorities to help where they can.
Savannah has been off work since her mother's abduction and has dropped out of hosting NBC's coverage of the Milan Winter Olympics, which begin on Friday.
She joined her two siblings in an emotional plea on social media Wednesday to say they're ready to talk to whoever sent the ransom notes.
'We need to know without a doubt that she is alive and that you have her. We want to hear from you and we are ready to listen. Please reach out to us,'
she said while fighting off tears.
With her voice cracking, she addressed her mother directly, saying the family was praying for her and that people were looking for her. She was flanked by her brother Camron and their sister Annie.
'Mamma, If you're listening, we need you to come home. We miss you,'
Annie added.
