Key detail in Nancy Guthrie's ransom note points to local suspect: TMZ founder

A TMZ host revealed on Thursday that the person who abducted Nancy Guthrie, the 84-year-old mother of "Today" show co-host Savannah Guthrie, likely lives in Guthrie's hometown of Tucson, Arizona.

Nancy Guthrie likely disappeared on Saturday morning sometime between 1:45 a.m. and 2 a.m., according to evidence released by investigators. She was last seen at her home in Tucson, where she was dropped off after dinner with friends.

A ransom note was delivered to TMZ and investigators this week. TMZ founder Harvey Levin said on CNN's "Erin Burnett OutFront" that after reviewing the letter, he got the sense that it was written by a local.

"I just want to make this really clear that this is just my opinion, just based on analyzing it, that my sense and ... we've talked about this at length today, my sense is that whoever sent this letter is based in the Tucson area," Levin said. "And I say that because of a reference made in the letter, a sentence in the letter, it feels to me, reading it, that this is Tucson-based."

Levin said the ransom letter makes mention of a local television station that people who are unfamiliar with the city wouldn't necessarily know about.

"It doesn't seem like someone out of state or out of the country hatched this plan," Levin said.
