Chris Nanos, the Pima county sheriff leading the investigation in Tucson, has been accused of bypassing federal analysts, according to an unnamed source at the FBI who spoke to Reuters. The sheriff reportedly sent the evidence in question to a private lab in Florida. It included DNA evidence and gloves recovered in a search close to the home just north-east of Tucson from where Nancy Guthrie, Savannah Guthrie's mother, was reported missing on 1 February.
