Nancy Guthrie disappearance: Person of interest detained

Authorities detained an unidentified person of interest Tuesday night in the case of missing 84-year-old Nancy Guthrie, just hours after SWAT vehicles were seen leaving the Pima County Sheriff’s Department. The development follows a missed Feb. 9 ransom deadline and reports of a $300 Bitcoin deposit made to an account linked to the alleged abductors of Guthrie.
