Well my line of thinking is that the first room they go into is the bedroom that the kids are in and a sleepy Madeleine immediately wakes up, perhaps thinking it's her parents, they get a scare and cover her mouth and panic about what to do and accidentally smother her to death. They panic even further and bolt out of the window, thinking that the McCanns are next door and it's better to hide the evidence (her body) than to leave it there, but once they get outside they realise that running around carrying a little dead girl looks more suspicious than walking calmly as if she's asleep, so they go their separate ways (or it's one man acting alone) and one of them carries the body down to the beach or another location to get rid of the body. Maybe they take her out to sea and dump her there or maybe somewhere on land.
