Probe intensifies with the emergence of new evidence in a high-profile case.

The search for Nancy Guthrie, mother of Today show host Savannah Guthrie, has taken a troubling turn. Investigators discovered that her medical device stopped syncing with her Apple Watch during the early morning hours, with the watch found inside her home.

This new information has helped establish a clearer timeline of events. Nancy was last seen at her home late Saturday evening. Concern arose when she was absent from church the next morning, prompting friends to request a welfare check.

Inside the home, investigators found concerning signs, leading them to classify the residence as part of an active criminal investigation. Authorities have not disclosed specific details but indicate evidence of outside involvement. Nancy requires daily medication, heightening the urgency of the search.

Local, state, and federal resources are collaborating, reviewing surveillance footage and interviewing neighbors in the search effort. Law enforcement urges anyone with information to come forward, regardless of its significance.

Savannah Guthrie has temporarily stepped away from her TV duties to support her family during this challenging time. She appreciates the support and prayers from across the country. Authorities and loved ones remain hopeful for Nancy's safe return as the investigation progresses.
