Something went drastically wrong that evening. Given the removed screen at the front of the house, it's plausible that someone broke in after everyone had gone to bed. There were an awful lot of lights on when the dad got home, but the mother claims to have been passed out drunk and didn't notice anything.
If the back door was unlocked, that was a likely exit point. If the backdoor was key locked and the front door was unlocked, that would be the likely exit point. If both doors were locked, it's unlikely that a random stranger broke in because it wouldn't be possible to remove an infant through the unscreened window without some assistance. If a couple kidnapped the infant, someone would have figured it out by now. I think that if the front door was unlocked, it's quite possible someone that knew there was an infant at the house broke in and took Lisa away. If it was locked, then something happened to Lisa before the father came home.
It is pretty weird to have an infant stolen ... who would do that other than a crazy woman that wanted a baby? Since when do men want to kidnap crying infants? How could a crazy woman sneak out of a small window with a baby ... who knew that there was a baby there? Maybe it was the mother, maybe an intruder ... hard to figure out.
