BREAKING: One person detained in Nancy Guthrie case

Fox News Digital confirmed a person of interest in the disappearance of 84-year-old Nancy Guthrie has been detained on Tuesday night.

Guthrie was last seen on the night of Jan. 31 from her home in the Tucson, Arizona area. Since then, there have been reports of ransom notes, a blood trail from her home, and recovered surveillance footage from her home of her possible abductor.

On the night of Tuesday, Feb. 10, investigations involving the Pima County Sheriff's Department and the FBI have ramped up in the county. SWAT vehicles were seen leaving the sheriff's office just hours before the person of interest was detained.

Former sheriff's detective and investigator Jamie Copenhaver joins LiveNOW's Austin Westfall to react.
