I think it's possible that she simply didn't remember what the truth was.
I think she could have already felt very guilty about the fact that her daughter was missing under her watch so she may not have initially told the police she was drinking because she didn't want to look bad. Maybe she thought her daughter would be found ASAP and to save face, didn't bring up the alcohol. Then she went on to say she turned off the lights and checked on her baby because that's what she NORMALLY does, so she must have done it that night as well. Maybe she turned the overhead lights off, but left the lamp on, and the kitchen appliance lights on. Maybe that's what she meant when she says she turned the lights off? Who knows. Then the police find the video of the wine. She realizes that she's *caught* and comes clean. Says she didn't mention it because she thinks it has no bearing on her child being missing. She knows she didn't do it, therefore someone must have taken her. So when police confront her she goes on to confess that no, because she was drunk, she really doesn't remember if she turned off the lights (but that's what her neighbor told her) or checked on Lisa.
^^all my speculation^^
I'm not saying if she did do what's above that it was right by any means, but by the time everything would have come out in the media, she was already crucified. It seems that "inconsistencies cleared up" by the families in these cases often turn into "the family changing their story" for



reason. Now people find out she left out she was drunk. Her ship was sunk. If it's the case, it was most definitely self serving, but maybe she truly believed it had nothing to do with baby Lisa (the drinking happened hours earlier), maybe it (drinking) wasn't out of the norm, and maybe she figured Lisa would be found right away.
I admit that I was ALL over Debbie in the beginning.
Now I can't help but think if they had something on her, anything on her, that we would have seen more by now. Something. Then I think about how I would react if my child was missing on my watch. And what if I was drunk when it happened? I probably wouldn't want to show my face in public either. I hope I never find out. I think of the people here, myself included, who complained, why aren't they talking, why aren't they out there...now people say they protest too much and dissect every word they say and they are only out there for self serving purposes.
