Savannah Guthrie has reportedly spent $500,000 on private investigators to try and solve the case of her mother Nancy Guthrie's disappearance.
A source told the US Sun that Savannah is 'not prepared to stop looking' for her mother and feels that relying solely on the official investigation is not enough.
However, NewsNation senior national correspondent Brian Entin could not confirm the report and stated that he hasn't 'heard anything about any private investigators.'
The Pima County Sheriff's Department has faced criticism for the handling of the investigation, with Sgt. Aaron Cross describing it as a 's— show' due to a lack of communication between detectives.
Savannah Guthrie has expressed frustration with the pace of the investigation, with a report claiming she is 'incredibly upset' after the sheriff stopped personally communicating with the family.
Pima County Sheriff Chris Nanos has acknowledged the family's frustration but remains confident that answers will come, stating that his team will 'solve this' and that it just takes time.
