New “20/20” Chronicles a Mountain of Lies in the Mysterious Death of Toni Henthorn

“GMA3” co-anchor Eva Pilgrim examines Toni Henthorn’s suspicious death.

This week’s brand-new edition of ABC’s 20/20 uncovers a mountain of lies in the investigation into the mysterious death of Toni Henthorn.

What’s Happening:

  • Accomplished ophthalmologist Toni Henthorn lived with her family 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.
  • 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 GMA3 co-anchor Eva Pilgrim, sharing her story and memories of her mother.
  • The all-new 20/20 airs on Friday, February 28th (9:01-11:00 p.m. EDT) on ABC, streaming the next day on Hulu.
