The hunt for missing Arizona grandmother Nancy Guthrie shifted sharply towards the US–Mexico border this week, after a volunteer group in northern Mexico said it received an anonymous tip on Wednesday claiming Guthrie's remains were buried in an unmarked grave near Nogales.
For context, the 84‑year‑old mother of Today anchor Savannah Guthrie was last seen on 31 January. Her disappearance from her home in Pima County prompted a sprawling investigation in Arizona and an emotional public appeal from her daughter, who has offered a reward of up to $1 million for information leading to her recovery. Despite that huge incentive and extensive local searches, authorities have yet to identify any suspects or even name a person of interest.
