Savannah Guthrie’s brother-in-law is an Italian writer and creative named Tommaso Cioni , who is married to her sister, Annie Guthrie.

Who he is

  • His name is Tommaso Cioni.
  • He is married to Savannah’s sister, Annie Guthrie , which makes him Savannah’s brother-in-law.
  • He has lived in Arizona for years and has described himself as someone who writes, studies lizards, plays electric bass, and makes homemade pasta, according to a short bio cited in recent coverage.

Why he’s in the news now

  • Cioni has been widely mentioned because he was reportedly one of the last people to see Savannah’s mother, Nancy Guthrie, before she went missing from her Tucson-area home in late January 2026.
  • Reports and commentary say he dropped Nancy off at home after dinner and ensured she got inside, placing him near the end of the known timeline.
  • Some media and true‑crime commentators have speculated about his role, but law enforcement has publicly stated that they have not named any official suspects or persons of interest , and have warned against treating unverified speculation as fact.

Forum and trending discussion angle

Across social media, forums, and YouTube true‑crime channels, people are debating:

  • Whether it’s fair for commentators to focus so heavily on the brother‑in‑law when police have not confirmed any suspect.
  • The emerging narrative that a “brother‑in‑law suspect” makes for a gripping story versus the reality that the case is still unfolding and all individuals remain presumed innocent.

Many discussions emphasize waiting for verified updates from investigators rather than drawing conclusions from incomplete timelines or rumor-heavy coverage.

TL;DR:
If you’re asking “who is Savannah Guthrie’s brother in law?” the name you’re looking for is Tommaso Cioni , her sister Annie’s husband, currently in the news only because he was reportedly among the last people to see her missing mother, with no official suspect designation from police so far.
