The family of missing 84-year-old Nancy Guthrie have offered $1m for her recovery.
NBC Today show co-host Savannah Guthrie said on Instagram that “someone knows how to find our mom and bring her home” on Tuesday, and urged people to keep Ms Guthrie in their thoughts.
The 84-year-old went missing more than three weeks ago after she failed to appear at church on 1 February.
She was last seen at her home in Tucson, Arizona, on the evening of 31 January. Authorities believe she was kidnapped, or otherwise taken against her will.
The TV presenter said in the video: “Please keep praying without ceasing. We still believe. We still believe in a miracle.
“We still believe that she can come home, hope against hope, as my sister says. We are blowing on the embers of hope.
“We also know that she may be lost. She may already be gone.”
