This surely has been discussed but there are so many posts I can't read them all. Jayme and her mother his in the bathroom and heard the shot that killed her father. If they hadn't already called 911, they surely did then. After killing James, JP walked around the house looking for people, then took multiple tries to get into the bathroom, then found Denise and Jayme, and told Denise to hang up the phone. Denise and Jayme are presumably dead silent in the bathroom to avoid attracting his attention. How does this gel with the description we have been given of the 911 call having screams in the background, nothing understandable on the call? Wouldn't they have heard him tell her to hang up, and where were the screams in the background coming from?
