Investigators in Tucson, Arizona, are still trying to establish where Nancy Guthrie is 88 days after she vanished from her home, with journalist Brian Entin saying the case has hit 'a lot of dead ends' and still has no suspects or major breakthroughs.
The 84 year old, mother of Today co host Savannah Guthrie, was last seen at her house on the night of 31 January. Police say the investigation remains active despite the apparent slowdown.
