What Happened to John Andrew Ramsey?

Neighbor Melody Stanton says she heard a scream between midnight and 2 a.m. This same woman did say at the very early stages of the investigation that she had nothing to offer. Andrew Vermeer and Luke Vermeer, they went to bed after watching movies. They didn't see anything unusual. Everything was typical for that time of night.
