NANCY GUTHRIE MISSING 4 MONTHS, SEARCH AT CHILLING TURNING POINT

Four months after the heartbreaking kidnapping of fragile, 84-year-old Nancy Guthrie, Nancy Grace breaks down the latest dramatic developments and critical turning points in the ongoing investigation. Nancy and her panel of experts explore the intense friction between local law enforcement and the FBI, exposing how federal assets and world-class forensic labs were allegedly sidelined during the most crucial early days of the disappearance.

Meanwhile Nancy's daughter, Savannah Guthrie launches her own $500,000 private investigation, possibly fueled by reservations about the Pima County Sheriffs handling of the case. The panel analyzes why a sudden lack of follow-up on early ransom notes has led experts to believe the abduction was a personal act of revenge rather than a scheme for money, and reviews how vehicle black boxes, Uber data, and Ring camera caches are being leveraged to track down the perpetrators; new tips claiming the trail leads directly into Sonora, Mexico. Anyone with information on Nancy Guthrie's whereabouts is urged to call the FBI at 1-800-225-5324. There is a $1.2-million reward to help bring Nancy Guthrie home.
