Authorities in Arizona are still searching for Savannah Guthrie's missing mother, more than three weeks after she was reported missing.
The Pima County Sheriff's Department said its investigation into the disappearance of 84-year-old Nancy Guthrie remains active, and there have been no changes in resources. The Feb. 21 statement came as investigators continue working to identify the masked man seen at Guthrie's front door the morning she disappeared in security camera footage that the FBI released almost two weeks ago.
Authorities have said Guthrie, who was last seen on Jan. 31, was taken from her home against her will. She takes daily medication, and if she does not receive it, "that could, in itself, prove fatal," Pima County Sheriff Chris Nanos warned earlier this month.
No arrests have been made. DNA evidence has been collected and submitted for analysis, though authorities have warned this process will take time. But investigators have been making progress as they seek to identify the clothing worn by the suspect in the security camera footage, according to Nanos.
