Nancy Guthrie's family has been at the center of a high-profile abduction case, with her son-in-law Tommaso Cioni and daughter Annie drawing attention from investigators.
A 'no trespassing' sign has been placed outside their home, warning violators of prosecution, amid increased media attention and public interest in the case.
The sign surfaced shortly after complaints at a homeowners' association meeting about a YouTuber allegedly 'harassing residents.'
Meanwhile, investigators are continuing to analyze potential DNA evidence linked to the case, with the FBI conducting further testing using advanced technology.
The Pima County Sheriff's Department has confirmed ongoing efforts in coordination with federal authorities, with officials hoping the testing could help identify the person or persons responsible for the abduction.
Savannah Guthrie has largely remained private as the investigation unfolds, but recently showed support for her family on social media.
