I don't have a doubt in my mind that her story about being drunk is the truth. Lots of evidence points to it being the truth. If it walks like a duck, talks like a duck, and SAYS it's a duck...it's most likely a duck, imo.
What bugs me is that she has the nerve to admit that it's possible she blacked out in one breath, and in the next breath practically defies us to believe it's possible she had anything what-so-ever to do with her daughter's death. Can't have it both ways, Debbie. Can't use the "blacked out" excuse for not knowing what happened to your daughter, and then state with ANY degree of certainty that you didn't have anything to do with it. Sorry.
