Pima County Sheriff Chris Nanos said he does not believe a new ransom note claiming to know who kidnapped Nancy Guthrie is genuine. “I think the FBI has done a number of arrests for false or fake ransom notes. I think we’re looking at another one of those today with what’s been reported. But we’ll let the FBI do their work,” Nanos said on the June 26 episode of 1030 KVOI AM’s The Buckmaster Show. On Friday, TMZ received a note from someone claiming to have a video of Nancy Guthrie on the day of her death, as well as a video of the “main guy” responsible for her disappearance. TMZ, which forwarded the note to the FBI, reported that the email came from the same address that has been sending similar letters hinting at the identity of her captors for months. “It is a shame that these types of events occur. People have great interest and that’s good because it helps us but then it gets really abused,” Nanos continued in his interview with host Bill Buckmaster. The note comes amid conflicting reports from TMZ and NBC News about the veracity of certain letters from her captor and their contents.
