Today show host Savannah Guthrie marked a chilling anniversary with a gut-wrenching Instagram post Saturday morning. Australian-born presenter Savannah Guthrie poses alongside her mother Nancy Guthrie during a production break whilst hosting NBC's "Today Show" live from Australia at Sydney Opera House on May 4, 2015 in Sydney, Australia. Police released details on Friday of the two ransom notes that were sent to the Guthrie family after Nancy was taken. Savannah Guthrie has made numerous public pleas for the kidnappers to reveal where to find Nancy’s remains, but there are no suspects and no leads on the 84-year-old’s whereabouts. Savannah Guthrie posts on Instagram on the six month anniversary of her mother's disappearance.
