Sheriff accused of blocking FBI access to crucial evidence in Nancy Guthrie kidnapping

Federal officials are accusing the Pima County Sheriff's Office of withholding "key evidence" in the kidnapping of Nancy Guthrie, Reuters reported on Thursday.

"The FBI asked Pima County Sheriff Chris Nanos for physical evidence in the case, including a glove and DNA from the home of 84-year-old Nancy Guthrie, to be processed at the FBI's national crime laboratory in Quantico, Virginia, but Nanos has insisted instead on using a private lab in Florida, the official said," per the report.
