More than 750 credible tips have been received by the FBI after Savannah Guthrie, the US television presenter, announced a $1m family reward for information leading to the discovery of her missing mother, Nancy Guthrie. The 84-year-old has been missing since 1 February from her home in the Catalina Foothills near Tucson, Arizona.
In an Instagram video, Savannah Guthrie said: 'We still believe in a miracle. We still believe she can come home. But we need to know where she is. We need her to come home. For that reason, we are offering a family reward of up to $1m for any information that leads us to her recovery.' She also announced a $500,000 donation to the National Center for Missing and Exploited Children.
The family reward adds to an existing $100,000 FBI reward and a $102,500 reward from local Crime Stoppers affiliates. The bureau has fielded more than 22,000 calls since Nancy Guthrie's disappearance. Local news outlets have reported receiving unverified ransom notes demanding millions of dollars.
Nancy Guthrie relies on daily medication and has medical conditions including high blood pressure, a pacemaker and cardiac issues. Police have not named a suspect and have released few leads. Security footage shows an armed man in a ski mask with a backpack tampering with her security camera on the morning she vanished.
A pair of gloves found two miles from her home did not match DNA from the property or any profile in the FBI's national database. The masked man, described as 5ft 9in to 5ft 10in with an average build, may have visited the property on another day, though local police have dismissed this as speculation, noting that doorbell images lack timestamps.
Police have asked nearby residents for video footage from early January, particularly late on 11 January and the morning of 31 January. Volunteers have searched the countryside, but authorities have urged the public to leave such work to professionals.
