The FBI is investigating letters from sick trolls menacing “Today” show co-host Savannah Guthrie with threats about her missing mother — as the feds are pouring resources behind Arizona police desperately searching for the 84-year-old grandmother.
One letter sent to Guthrie was from a nutcase who said he had knowledge of the abduction — but also included a slew of slurs. The writer also made reference to accused murderer Luigi Mangione and the Jan. 6 US Capitol riot, according to law enforcement sources.
And that’s just one of numerous letters that have been emerging since Guthrie’s mother, Nancy, disappeared from her Tucson home Saturday night.
Other notes have been sent to news outlets like TMZ and included purported details from inside Nancy’s home, claims about what she was wearing when she was taken — and even multimillion-dollar ransom demands to be paid in bitcoin.
Detectives with the Pima County Sheriff’s Department are leading the investigation, but the FBI has opened up its sprawling resources to supplement the local cops, sources told The Post.
Federal forensics specialists are helping to analyze the purported ransom letters and follow tips outside Tucson, while the bureau has been poring over cellular tower data to see who passed through Nancy’s neighborhood on and around the night she vanished.
Warrants to search Nancy’s digital accounts — which could help track her movements — are also being expedited by the FBI, while its agents have been deployed to circumvent Arizona jurisdictional restrictions and follow up in-person leads, sources said.
Customs and Border Protection has even joined in — Tucson is just 70 miles from the Mexican border — to provide sniffer dogs for ground searches.
The federal aid comes as President Trump personally affirmed he would provide whatever resources he could to help with the investigation while speaking to reporters in the Oval Office Tuesday.
“I always got along very good with Savannah. Very unusual situation, but we’re going to find out,” said Trump, who has been interviewed by Guthrie in the past.
“I’m going to call her later on. I think it’s a terrible thing,” he said.
