FBI releases images of an 'armed' person in a ski mask from Nancy Guthrie doorbell camera video

• Authorities have released new images related to the disappearance of Nancy Guthrie.
• The mother of "Today" show host Savannah Guthrie was reported missing on February 1.
• The images, including video, show an "armed" person in a ski mask at Nancy Guthrie's door.

Authorities investigating the mysterious disappearance of "Today" show host Savannah Guthrie's mother, Nancy Guthrie, have released images of a masked person who they say was armed and appeared to mess with the elderly woman's doorbell camera the day she vanished.

The black-and-white photos and video clips, released to the public by the FBI and the Pima County Sheriff's Department on Tuesday, were recovered from the Nest doorbell camera on Nancy Guthrie's Arizona home and show a person wearing a full-faced ski mask.

Authorities described the person as an "armed individual." In the images, the person is seen wearing a backpack and gloves, and holding a flashlight in their mouth. Videos show the person appearing to use plants to block the front porch doorbell camera.

"Law enforcement has uncovered these previously inaccessible new images showing an armed individual appearing to have tampered with the camera at Nancy Guthrie's front door the morning of her disappearance," a statement posted on FBI director Kash Patel's X account Tuesday read.

Authorities believe Nancy Guthrie was taken from her home, just outside Tucson, in the Catalina Foothills, against her will, 10 days ago. The Pima County Sheriff's Department has said that blood discovered on the porch matched to her.

The 84-year-old woman, who has limited mobility, a pacemaker, and depends on daily medication for a heart condition, was reported missing by her family on February 1 after she was last seen the night before when they dropped her off at home following a dinner.

For days, authorities were unable to access the footage from Nancy Guthrie's doorbell camera, which they said suddenly disconnected at 1:47 a.m. MST on February 1. The doorbell camera had also been removed, Pima County Sheriff Chris Nanos has previously said.

On Tuesday, the authorities said they have been working closely with private sector partners "to recover any images or video footage from Nancy Guthrie's home that may have been lost, corrupted, or inaccessible due to a variety of factors - including the removal of recording devices."

"The video was recovered from residual data located in backend systems," said the Tuesday statement from authorities, which was shared by Patel and the Pima County Sheriff's Department.

Videos recovered from the doorbell camera were released by Patel in separate X posts.

Law enforcement officials have not identified any persons of interest or suspects in the case, which has captured national attention amid reports of purported ransom notes and emotional video pleas by Savannah Guthrie and her siblings.

On Monday, the famed NBC anchor posted an Instagram video, telling her nearly two million followers: "We are at an hour of desperation, and we need your help."

"Law enforcement is working tirelessly around the clock trying to bring her home, trying to find her. She was taken, and we don't know where," Savannath Guthrie said as she called the situation a "nightmare."

On Tuesday, Savannah Guthrie also shared the doorbell images on her Instagram account in a post that said: "We believe she is still alive. Bring her home."

The FBI, which is assisting in the case, has offered a reward of up to $50,000 for information related to Nancy Guthrie's disappearance.

Anyone with information related to the case is being asked to contact 1-800-CALL-FBI (1-800-225-5324) or the Pima County Sheriff's Department at 520-351-4900.
