I'm still baffled by this case.
If it were an intruder, it seems unlikely that Mom or the kids wouldn't wake up. It's possible Lisa would wake when lifted. Whether the lights were turned on by the intruder or the son getting up, you'd think that would be noticed. Plus, it seems odd to take the cell phones off the counter. There's no clear entrance/exit. There's not a lot of clues to go on here.
But - there's not much for the parents, either. How would they get Lisa out of the house without her siblings noticing? Hide the cells? Hide them so well, in face, that they still haven't been found? Then, we have the man carrying the baby sighting in the middle of the night, as well as the suspicious bicycle rider, the handyman, and the teen. There's also exes involved, which statistically can lead to messy situations. The fact that Lisa was taken out of the house quietly points to someone who knows the family, thus making them more confident in navigating the house, or someone who's been watching.
To me, how the parents come across in interviews means very little - they're damned if they do and damned if they don't in every aspect of their behavior, actions, appearances, affect, and tone of voice. Little things like whether they've brushed their hair are picked apart, but in the end, mean nothing. We've had cases where people have been ripped, and turned up innocent. Others come across sympathetically, and are guilty. Behavioral observations are an inexact science. I can't really use their appearances and statements to help me down off the fence.
And then we have LE. They've certainly acted different than I see other LE act in similar cases. The FBI is back seat on this. There's no reward. There's a very public split with the parents for some time, which to me, came across as a bit unprofessional. There are "cofirmed" unnamed LE sources leaking things that Young then disagrees with. At the beginning of this case, there were only 47 tips - so low! The tips are still low. There's no reward. There seems to be very little urgency on the part of LE. They keep searching the same areas. They won't release what they're looking for, who has been cleared, or any real information on the status of the investigation. Most odd, they say things like they challenge others to think of something they hadn't, or that they're waiting for the next idea to come in. I can't tell if they're playing cat and mouse, or if they simply have nothing.
