NEW YORK, NY— Authorities expanded their search for Nancy Guthrie, the mother of “Today” show host Savannah Guthrie, as the investigation entered its fifth day and officials continued to probe what they believe may have been an abduction.
Guthrie, who has said she lives in Brooklyn Heights, has shared repeated public appeals for her mother’s return.
Nancy Guthrie, 84, was last seen Saturday night at her home in the Catalina Foothills area north of Tucson, according to the Pima County Sheriff’s Department. Her family reported her missing Sunday after she failed to attend church, authorities said.
Sheriff Chris Nanos said investigators believe Guthrie was taken from her home while asleep. No suspect or person of interest has been identified, and authorities do not know whether she was targeted.
“We don’t know where she is, and we don’t know why this happened,” Nanos said a news conference on Tuesday.
The sheriff’s department scheduled a new briefing on the case for 1 p.m. ET on Thursday.
Guthrie’s children released a video message Wednesday pleading for her safe return.
“Everyone is looking for you, Mommy, everywhere,” Savannah Guthrie said in the video. “We will not rest. Your children will not rest until we are together again.”
Authorities said Guthrie has limited mobility and relies on medication that could be fatal if not taken within 24 hours.
“She is 84 years old, her health, her heart is fragile,” Savannah Guthrie said. “She lives in constant pain. She is without any medicine. She needs it to survive. She needs it not to suffer.”
The FBI has joined the investigation and is sending additional agents and specialists to assist local authorities, according to sources familiar with the matter.
Investigators are also reviewing possible ransom letters sent to media outlets. The Pima County Sheriff’s Department said it is working to determine whether the letters are legitimate.
An ABC Tucson affiliate reported receiving one of the letters and turning it over to law enforcement. CBS affiliate KOLD News also confirmed receiving similar communications.
Addressing reports of ransom notes, Savannah Guthrie said the family is prepared to engage, but urged caution.
“As a family, we are doing everything that we can,” she said. “However, we live in a world where voices and images are easily manipulated. We need to know without a doubt that she is alive and that you have her. We want to hear from you and we are ready to listen.”
Authorities urged anyone with information to contact the Pima County Sheriff’s Department or call 911.
