For the first time since the disappearance of his mother-in-law Nancy, Savannah Guthrie’s husband has broken his silence.

On Tuesday, Michael Feldman took to Instagram to appeal for assistance in identifying a masked individual seen at the 84-year-old’s residence the night she vanished.

The 57-year-old urged, “Someone out there may recognize this person. Please help us. Bring her home.”

He included unsettling photos of the suspect, which were released by the FBI and local authorities, alongside his plea for help.

Feldman and Guthrie, who are parents to son Charles and daughter Vale, were married just outside Tucson, Arizona, and now reside in Brooklyn.

The city of Tucson has become the focal point of the search for Nancy, who was abducted from her home in the early hours of February 1.

Bar the disturbing video released by officials on Tuesday, there has been little new information about the case. 

Savannah also shared the video to her own social media page saying: ‘Someone out there recognizes this person. We believe she is still out there. Bring her home.’

Nancy was last seen entering her home in Tucson on the evening of January 31 after having dinner with her daughter, Annie, and son-in-law, Tommaso Cioni.

The next morning, she was reported missing after failing to attend a virtual church service with friends, Pima County Sheriff Chris Nanos said. 

Since then, law enforcement has continued to comb over the home, which sits on a large lot on a street with no lights, while Savannah and her two siblings, Anne and Camron, plead for help in finding their mother. 

Annie and Cioni realized she was missing around 11.10am on February 1, the Pima County Sheriff’s Office said.

As officials continue their search, TMZ reported that a Bitcoin account referenced in ransom letters sent to media outlets has saw some activity after a deadline passed. 

The news website is one of three outlets that received alleged ransom notes in connection with Nancy’s abduction. 

Unidentified sources involved in the investigation told the outlet that officers believe the ransom notes were written by the kidnapper. 

Sources said the letters referenced specific damage to Nancy’s home and other details that have not been made public.

Nancy was reported missing to police at 12.03pm. Her phone, wallet, vital daily medications and car were still at her Catalina Foothills home. 

Cioni said he saw his mother-in-law enter her home through the garage before he drove off the night before at around 9.45pm MT.

Investigators found drops of blood on Nancy’s front porch – that were later confirmed to be hers – and that her doorbell camera was disconnected at around 1.45am. 

Less than 30 minutes later, her security camera detected movement. Her pacemaker stopped transmitting data to her Apple Watch and phone shortly afterwards, suggesting she had been taken out of the devices’ range. 

Nancy requires medication every 24 hours and it is unclear if whoever abducted her has ensured she has access to her medication. 

Police detained a delivery driver on Tuesday evening but he was released hours later after a search of his home. 

Carlos Palazeulos told reporters: ‘They held me against my will, they didn’t even read me my rights two hours in.’

When asked if he had known who Nancy was, he told reporters ‘no’ and that he had been followed by police while out on deliveries. 

‘They told me to stop moving. What the f*** am I doing here? I didn’t do anything to be honest, I’m innocent.’

Palazeulos added that he had no idea who Savannah was either, saying he did not watch the news and that officers had not asked him any questions. 

Authorities also carried out a search of his home near Interstate 19, he was released shortly after 1am local time.
