Feb. 4 (UPI) -- Law enforcement officials in Arizona said Wednesday they have not identified a suspect as they enter the fourth day searching for Nancy Guthrie, the missing 84-year-old mother of Today host Savannah Guthrie.

In a statement posted to X early Wednesday, Pima County Sheriff Chris Nanos said investigators also haven't identified any people of interest in the case. Officials believe Nancy Guthrie was kidnapped from her Tucson-area home in the early hours of Sunday. She was was last seen around 9:45 p.m. MST Saturday and was reported missing after she failed to attend church the next day.

"Detectives continue to speak with anyone who may have had contact with Mrs. Guthrie," Nanos said in the statement.

"Detectives are working closely with the Guthrie family. While we appreciate the public's concern, the sharing of unverified accusations or false information is irresponsible and does not assist the investigation."
