Bombshell TMZ email claims to have video of Nancy Guthrie's kidnappers: report

A source who claims knowledge of the identities of Nancy Guthrie's kidnappers claims to have enough evidence to deliver them up to authorities on a "silver platter."

TMZ received an email from the source claiming to have video showing the "main guy" with the mother of NBC News broadcaster Savannah Guthrie on the day the 84-year-old allegedly died, and the outlet says it has authenticated the email as coming from the same person who sent previous messages.

"I have a phone stashed in a secure location guaranteeing both the information it stores and the safety of the phone," the source said. "What it contains is my definition of delivering them on a silver platter, a short video of the main guy with nancy the day that was probably her last, pictures of both involved, names and addresses and age."

The phone, the source added, is in a "location easy to access if you know where it is."

The source told the outlet he would provide more information in exchange for Bitcoin, and TMZ asked for one screen shot of Nancy Guthrie to authenticate his claim and forwarded his email to the FBI.
