I think DB told the truth from the git go, at this point. the fact she may or may not have spoken of her "guzzling wine" as JVM put it last night, could have been because she didn't want the focus on her instead of the perp.
People, even children are stalked all the time. I see little credible evidence DB did anything to this child yet, and an abduction makes far more sense than planning on finding a kitten to mask the smell of death, changing out a rug with media trucks and neighbours watching the home, JI getting this job just to be out of the house at the appropriate time, or, an excuse to get her hair done.
Evidence DB did this so far, IMHO, amounts to no more than DB bashing.
