Homicide investigators Monday were asking the public for help after Nancy Guthrie, mother of Today journalist Savannah Guthrie, went missing. Police said a "crime scene" had been discovered at her home in Pima County, Arizona.
Authorities called the circumstances involving the disappearance suspicious.
"We do in fact have a crime," Pima County Sheriff Chris Nanos said during a press conference Monday.
The 84-year-old woman was last seen on Jan. 31. More details about her disappearance and what cops found at the home were not released.
Nanos said that authorities were relying on the community and technology to try and find Guthrie, who has limited mobility and needs medication.
"She did not leave on her own, we know that," Nanos said.
Her family was cooperating with authorities to investigate her disappearance. Officials were looking at cameras located at the home. The incident was not related to dementia.
"This is not dementia-related. She is sharp as a tack," Nanos added.
