This is more idle speculation and supposition, but I read that one of the party saw a man carrying a child out of the apartments after Gerry had been to 'check' on her.
I wondered if perhaps Gerry knew this man had taken her - alive or otherwise - Gerry was apparently chatting to some other person for a few minutes at the time, on his way back to the bar. Possibly stalling or something?
Nobody knows of course but I wondered if anyone else had thought of it.
I have concluded that I am posting on here as reassurance that my thoughts/suspicions are perhaps shared, not because I want actively to condemn anybody before they are shown to have done anything. Acknowledging that I haven't a clue about what really happened.
Also if Gerry is supposed to have said he presumed she had moved to the other room to get away from the babies crying, the picture that conjures up of crying babies being left completely alone for an hour or even half an hour at a time, is just appalling.
That was something I read but I don't know if it is true.
