On the show, they mentioned a neighbor who saw Joey on July 5th, walking with a baby stroller...she did not acknowledge his greeting, which he said was odd, and he did not see a baby in the stroller, which if true is even more odd.
I'm not sure what to make of the car parking, except that it had to be, IMO, either Joey or Alexis, the BF. I know the family said she could not have parked that way, but we really don't always know what people will or can do, IMO. And I always put my seat back to get out, or if I am going to sit in the car for a few minutes, which if she was driving, she may have done, while she decided where to go, for example.
I just can't imagine a motive for Alexis to harm the baby, or Joey for that matter...there was not any talk of abuse, just arguments and disagreements. Joey's mom said that Joey was developmentally a teenager and talked to anyone, anytime, which is why it seems so strange that she did not say hello to her neighbor. Something must have been going on with her at that time, I believe, mentally.
Still, I can't even begin to guess where she is, or what happened to her, or why the baby was killed...
