In a bombshell development that’s rocking the nation, authorities have dramatically turned their spotlight on the son-in-law of beloved Today show anchor Savannah Guthrie in the horrifying disappearance of her 84-year-old mother, Nancy Guthrie.

Sources close to the investigation reveal that detectives are no longer hunting a shadowy stranger – they’re zooming in on someone much closer to home: Tommaso Cioni, the 50-year-old AP biology teacher married to Savannah’s sister Annie.

And the pressure is mounting fast.

Police have reportedly towed and impounded a vehicle linked to the family – specifically Annie’s car – for forensic examination, with whispers of “significant blood” evidence at Nancy’s upscale Tucson, Arizona home sending chills down spines.

The back door was found wide open, cameras smashed (including Nest doorbell devices that were suspiciously disconnected or destroyed right around the time of the abduction), and blood spatter confirmed by lab tests to belong to Nancy herself.

“They’ve been tailing him for hours. The tone has completely shifted,” one insider spilled exclusively. “Investigators aren’t chasing a random intruder anymore – they’re facing HIM.”

The nightmare began on Saturday night when Nancy enjoyed what should have been a cozy family dinner and game night at Annie and Tommaso’s nearby home in the Catalina Foothills.

Cioni – described by some as a dedicated educator who’s lived in Arizona for years – drove the elderly mum home around 9:45-9:50 p.m., ensuring she was safely inside before leaving.

But sometime in the dead of night, between then and Sunday morning, terror struck.

Nancy never showed up for her regular church service – a red flag that sparked immediate alarm among her devoted children: Savannah, Annie, and brother Camron Guthrie.

What cops now believe was a brazen kidnapping unfolded in the quiet desert neighborhood, with Nancy – who relies on essential medications and has mobility challenges – taken against her will.

No forced entry signs? Check. Cameras deliberately disabled? Check. A family member as the last to see her alive? Double check.

The Pima County Sheriff’s Office, backed by the FBI, has refused to rule anyone out – including Cioni.

In a tense press conference, Sheriff Chris Nanos was blunt when grilled about the son-in-law: “We’re looking at everyone. Everybody’s still a suspect in our eyes.”

He added: “The family’s been very cooperative… but we would be irresponsible if we didn’t talk to everybody.”

While officials insist no official suspect or person of interest has been named yet, explosive reports from veteran journalist Ashleigh Banfield – citing a high-level law enforcement source with “impeccable” credentials – claim Cioni “may be the prime suspect now.”

Banfield revealed on her podcast that the shift came after intense interviews, with Cioni reportedly spending hours with detectives.

The vehicle seizure? “Towed, impounded, and now in evidence,” she said, linking it directly to the couple.

And the blood? Droplets on the porch and doorstep matched Nancy – a grim confirmation that violence erupted right at her front door.
