The mysterious disappearance of Nancy Guthrie, the 84-year-old mother of Savannah Guthrie, has taken a grim turn after a veteran prosecutor and expert on “no-body” murder cases suggested the investigation may now fit the profile of a homicide prosecution—even if no remains are ever found.

According to former prosecutor Tad DiBiase, authorities can successfully pursue a murder case without recovering a victim’s body if the circumstantial and forensic evidence is strong enough. He described the Nancy Guthrie investigation as a case that could potentially be prosecuted under that framework.

Nancy disappeared from her Tucson-area home in February, and investigators have long maintained that evidence suggests she was abducted. Despite months of searches, forensic testing, and FBI involvement, she has not been found. Authorities continue to follow leads, including recent tips alleging an unmarked grave near the U.S.-Mexico border, though searches have so far produced no confirmed evidence.

Importantly, law enforcement has not publicly declared the case a homicide, and the investigation remains active. Officials continue to seek information and have not announced any arrests or identified a suspect.

Still, the expert’s ᴀssessment underscores a troubling reality: after more than four months without a verified sighting, many observers fear the case may have shifted from a search-and-rescue mission to a search for answers.

For Nancy’s family, however, the goal remains unchanged—finding the truth about what happened on the night she vanished.
