The mystery surrounding the disappearance of Nancy Guthrie, the 84-year-old mother of NBC 'Today' co-host Savannah Guthrie, has taken another unsettling turn.

Despite thousands of tips, surveillance footage, reward increases and nationwide media attention, authorities have yet to locate Nancy Guthrie or identify a suspect.
