Good food for thought, thanks!
When the probable cause was published I drove myself crazy trying to put things together. Much of it fit but one thing that didn't quite mesh was the sighting by the truck driver of a man and woman walking up from the train tracks by Holt road. If the times in the PC are correct it would mean that either Willie or Taniasha would have been doing internet searches on the phone while they walked along the tracks - I just couldn't see that.
It's also interesting that Willie is seen on CCTV coming from the east on Henry and crossing Chase as he approaches the alley. Where was he coming from? IMO there's a possibility that, like you say, baby Delano was put elsewhere and not near the tracks.
The neighborhood is a little residential pocket surrounded by industrial buildings so there are a lot of "hiding" places. I took the little Google Map guy and "walked" that area extensively; not only are there commercial operations within walking distance but also many of the residents' garbage cans are in alleys, which provide privacy if someone is trying to dispose of something.
I won't be surprised if Willie ends up taking a plea deal as his trial approaches, maybe something like 20 or 25 years for manslaughter in exchange for taking LE to Delano's body; that seems to be the current trend for murderous caregivers. Even with no body the CCTV video and the internet searches are pretty compelling, along with what the neighbors heard. I imagine Willie's lawyer would encourage him to spill the beans rather than risk LWOP.
