Savannah Guthrie and her family have released a new statement about their missing mother, urging Tucson, Arizona, residents to come forward with potential clues about 84-year old’s Nancy Guthrie’s whereabouts.

In their statement on Sunday, the NBC Today show host and her siblings said: “We continue to believe it is Tucsonans, and the greater southern Arizona community, that hold the key to finding resolution in this case. Someone knows something. It’s possible a member of this community has information that they do not even realize is significant.”

“We hope people search their memories, especially around the key timelines of January 31 and the early morning hours of February 1, as well as the late evening of January 11,” the statement continued, referring to a date that investigators have previously expressed interest in without disclosing why.

Guthrie and her family continued: “We desperately ask this community for renewed attention to our mom’s case – please consult camera footage, journal notes, text messages, observations, or conversations that in retrospect may hold significance. No detail is too small. It may be the key.”

“We miss our mom with every breath, and we cannot be in peace until she is home. We cannot grieve; we can only ache and wonder. Our focus is solely on finding her and bringing her home. We want to celebrate her beautiful and courageous life, but we cannot do that until she is brought to a final place of rest,” they concluded.

Sunday marks seven weeks since the disappearance of Nancy Guthrie, who authorities believe was abducted from her home in the Tucson.

Alongside drops of blood discovered on Guthrie’s porch, investigators also recovered DNA from a glove found two miles from her home. The glove appeared to resemble one worn by a suspect seen in surveillance footage from the night of her disappearance. However, the glove was later discredited after it was discovered to have belonged to a restaurant worker, not the abductor involved in the case.

Authorities say the investigation remains active, with local and federal agencies continuing to analyze forensic evidence.

Over the last few weeks, investigators have canvassed nearby neighborhoods, reviewed hours of surveillance footage and conducted multiple interviews, though no arrests have been made.

In February, a man was detained in a traffic stop and underwent several hours of questioning “in connection to the investigation” before being ultimately released.

Since her mother’s disappearance, Savannah Guthrie has used her national platform to raise awareness, frequently sharing updates and appeals for information. Her family has offered up a $1m reward for any information about her mother.

Earlier this month, NBC confirmed that Savannah Guthrie plans to return to the Today show but offered no timeline on when she will resume her duties.
