AN ALL-NEW ‘20/20’ INVESTIGATES THE MYSTERIOUS DEATH OF TONI HENTHORN, WHO PLUNGED FROM A CLIFF WHILE CELEBRATING A WEDDING ANNIVERSARY

Toni Henthorn was an accomplished ophthalmologist with a seemingly perfect life that included a loving husband and a beautiful 7-year-old daughter named Haley. Toni and her family lived outside Denver, Colorado, where she had a thriving private practice. But when she and her husband Harold celebrated their 12th wedding anniversary with a hike in Rocky Mountain National Park, Toni fell to her death from a 160-foot cliff. “GMA3” co-anchor Eva Pilgrim examines Toni Henthorn’s suspicious death in an all-new “20/20,” airing FRIDAY, FEB. 28 (9:01-11:00 p.m. EST) on ABC and streaming next day on Hulu.

Toni’s shocking and fatal fall led the National Park Service and the FBI to investigate her death, leading them down a path that unraveled years of deception and raised questions about a second death. Now, nearly 13 years after her mother’s death, Toni and Harold’s daughter, Haley, speaks publicly for the first time in an exclusive interview with “20/20,” sharing her story and memories of her mother.
