I think this is where the idea that DB put Lisa to bed at 10:30 comes from.
First, LE says that she was last seen at 10:30.
Then, DB is asked about the last moments with Lisa and she describes putting her to bed.
-----
Reporter:
Do you remember your last moments with Lisa? I mean, what were you doing? What was it like?
DB:
Just change her, you know, put fresh clothes on her, and get her ready for bed, and gave her her bottle, and made sure her binky was in her crib in case she needed it, and she sleeps with her Barney, and she sleeps with her GloWorm and her blanket and that was, that was it.
