On New Years day in 2009, Kelly Osborn's daughter Sheena was found dead in a Bradenton Beach, FL hotel room. When police found her hanging, they quickly classified the death a suicide. But according to Osborn, her daughter had everything to live for and was not suicidal. So she began a quest to get the death classified as a homicide, and began her own investigation in search of the truth, which led her to Sheena's fiancé. David Muir reports on the evidence that was missed and the questions that were never asked. Is Osborn, in her grief, persecuting an innocent man? Anchored by Elizabeth Vargas and David Muir, "20/20? airs FRIDAY, OCTOBER 18 (10:00 - 11:00 pm ET) on the ABC Television Network.

David Sloan is senior executive producer of "20/20."
