Aug. 1 (UPI) — Two ransom notes sent by people claiming to be the kidnappers of Nancy Guthrie were released Friday by local police in hopes of generating new leads.

The second note, which was sent Feb. 6, told the Guthrie family that Nancy Guthrie died soon after she was kidnapped.

“We believe it was heart related,” the note said. “She is buried in nature now. Nothing you could have done could have changed the outcome. We want your family to know this and hope you all can find peace. We are truly sorry.”

Nancy Guthrie, 84, was the mother of Today co-host Savannah Guthrie. She was kidnapped from her home near Tucson, Ariz., on Feb. 1. The Pima County Sheriff’s Department marked six months since the kidnapping on Thursday and reiterated that the investigation is ongoing.

The family posted a new plea on Instagram Saturday.

“This is our beautiful Mom. Six months ago, someone took her out of her bed in the dead of night. We have lived every moment, every breath and every heartbeat in agony and despair ever since,” the post said. “Every day, we wake up and try to be strong and go on — because that’s what our joyful and resilient Mom taught us to do. But make no mistake — our hearts are in ruins.”

The post asks that people review the letters for possible recognition.

“We are begging for help. We are desperate. We need someone to come forward. Someone knows something. Someone suspects something. Someone recognizes the writing in the ransom demand notes. Someone has noticed something different, strange, troubling or just unusual — perhaps with someone they deeply love. … There is a way to end this situation and do the right thing. Please. Bring her home,” the post said.

The Pima County Sheriff’s Department posted the emailed ransom notes on X for the public to view, as well as a list of behaviors that could signal involvement.

The first note, which was sent on Feb. 2 to a local news outlet, noted that there was a white smartwatch on the floor at the foot of her bed, and that the backyard floodlight had been destroyed. It demanded $4 million in bitcoin by Feb. 5.

“Do not play games, law enforcement will not be able to help you,” the note threatened.

In July, a California man pleaded guilty to sending phony ransom notes to the Guthrie family to harass them.
