julianne,
There's a marked difference between an adult female's scream and a six-year-old female's scream. Melody Stanton easily identified the scream as that of a child and she estimates that it was about midnight to 2:00 AM when she heard it. The Stanton's slept with the bedroom window slightly ajar so, IMO, Melody Stanton did indeed hear JonBenet's scream.
In accordance with several experimental sound tests, the sounds to the outside were amplified by the air duct in the Ramseys basement, but were not heard in the bedroom on the top floor where John and Patsy slept.
However, there is one little fact seldom mentioned when the scream is discussed -- the Ramseys ALSO slept with their bedroom window slightly ajar. Therefore, IMO the Ramseys, like Melody Stanton, did indeed hear JonBenet's scream and, as a result, searched for and found JonBenet's dead body in the basement at around 1 to 2 AM.
John and Patsy, until Patsy's fake 911 call was placed at 5:52 AM, spent the rest of the morning covering up a crime COMMITTED BY CHILDREN.
