Savannah Guthrie's brother-in-law Tomasso Cioni has been missing for a week as police investigate the abduction of Guthrie's mother, Nancy Guthrie. Cioni was last photographed on February 3, two days after Nancy disappeared from her Catalina Foothills home in the middle of the night on February 1. The Pima County Sheriff Department has denied reports naming Cioni as a suspect in the case.

Police searched Cioni and Annie Guthrie's Tucson home twice in recent days, first on February 4 and again on February 7. During the second search, which lasted several hours, officials were seen carrying evidence processing tools and materials from the residence. Authorities did not need Cioni's consent or a warrant to search the home, as Annie Guthrie allowed access under US Supreme Court rulings permitting searches of shared residences with consent from one occupant.

The investigation has taken several turns, including reports of a ransom payment and claims about potential suspects. While Annie has appeared in social media videos seeking help, Cioni has remained out of public view since speculation about his involvement emerged. Police continue to investigate all leads in the high-profile case that has drawn significant media attention to the missing mother's disappearance.
