I really hope they've looked into her brother -
- he was around just before Lisa vanished...
- he knew DB was drinking that night...
- he knew JI was going to be out....
- he probably knew what DB was like when she drank...
- he knew the layout of the house....
- a neighbor saw a man with a baby....
- he could have walked in boldly and turned on lights knowing that there would be no issue if she woke up and found him.... and then taken advantage of the situation, maybe it was a spur of the moment thing ...
