Authorities were spotted conducting a late-night search of Annie Guthrie’s home as the search for her and Savannah Guthrie’s mom, Nancy, enters day seven.

Law enforcement were seen taking photographs at Annie and husband Tommaso Cioni’s Tucson, Ariz., home late Saturday until around 10:30 p.m. MT, according to NewsNations’ Brian Entin.

The outlet reported an agent carrying a silver briefcase into the home.

“This remains an active and ongoing investigation,” the Pima County Sheriff’s Department said in a statement Sunday. “Detectives and agents continue to conduct follow-up at multiple locations. Details of that follow-up are not being released at this time. Investigators have not identified any suspects, persons of interest, or vehicles connected to this case.”

The search comes as Savannah and her siblings, Annie and brother Camron, offered to pay their mother’s ransom in a heartbreaking video posted on Instagram Saturday evening.

“We received your message and we understand,” the “Today” anchor said. “We beg you now to return our mother to us, so that we can celebrate with her.

She added, “This is the only way we will have peace. This is very valuable to us, and we will pay.”

Former CIA officer and FBI special agent Tracy Walder subsequently told Page Six that the latest message felt “contrived” and “scripted.”

Walder said, “Is this a ransom for a dead body? Are we paying to get a body or a human back? Using words like ‘celebrate’ infers memorial or funeral, but it also infers they want to have a party when she comes home.”

Earlier on Saturday, a car and a camera were seized from Nancy’s home, as well as a floodlight as investigators are desperate for any clues to Nancy’s whereabouts.

President Trump claimed on Saturday that investigators were very close to cracking the kidnapping case, telling reporters that they’ve found “very strong” clues and believes “we could have some answers coming up fairly soon.”

The 84-year-old was last seen on Jan. 31 around 9:30 p.m. when her son-in-law Cioni dropped her off at home following a dinner with her daughter Annie.

The family called 911 on Feb. 1 after she failed to show up to church in the morning.

Savannah, who was set to host the Olympics in Italy, dropped her hosting duties and flew to Arizona to be with her family as the devastating search for her mother continued through the week.

On Monday, police announced Nancy’s home was considered a crime scene as they found blood belonging to Nancy on the porch of the Catalina Foothills home.

They also made the shocking announcement Monday that police believed she was abducted from her home in the middle of the night, which was later followed by confirmation of multiple ransom notes.

On Wednesday, Savannah and her siblings made their first desperate plea to their mom’s abductors in a devastating video.

“We live in a world where voices and images are easily manipulated. 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,” Savannah said, begging for the kidnapper to get in contact.

Camron posted another video to the kidnapper Thursday, confirming they wanted to talk.

Police have yet to ID a suspect or person of interest, telling the public they are “looking at everyone.”

The FBI confirmed earlier this week there is a $50,000 reward for any information that could lead to the rescue of Nancy.

Former CIA officer Walder told Page Six earlier this week, she believed Nancy had been “stalked for some time” before the kidnapping.

Meanwhile, Gayle King exclusively told Page Six Saturday that “everyone” within the broadcast community is “rallying around” Savannah.

“It’s very unsettling. It’s a very strange case, and there is still so many questions,” she told us. “Let’s hope people do the right thing. Somebody knows something. Now is the time for that somebody to speak up.”
