More than 80 days after 84-year-old Nancy Guthrie was abducted from her Catalina Foothills home in the early morning hours of Feb. 1, authorities still have no suspect in custody and no confirmed trace of the mother of NBC "Today" show co-anchor Savannah Guthrie.

Pima County Sheriff Chris Nanos and the FBI continue to describe the case as an active kidnapping investigation. Drops of blood believed to belong to Guthrie were found on her front porch, and surveillance footage captured a masked individual on her property that night. Her pacemaker disconnected from her phone around 2:30 a.m., suggesting she was taken from her bed and removed from the area quickly.
