Mine too. Reading between the lines (all speculation and MOO):
1. She has Uber/Lyft stickers on her car but drives jitney, no "official" trips (according to Uber) on a very busy weekend - maybe she was kicked off those services for bad customer experiences? I use these a lot so know that if you give someone 3 or 4 stars for being odd, bad driving, etc., they will get their driving privileges revoked.
2. Her husband (albeit through no choice of his own) left and took a child with him - maybe it was so she could work, maybe it was because she was emotionally unstable.
3. Her husband saying she COULD have done this - why would he say that? What does he know that we don't?
I am always HIGHLY suspicious of stories like this from a Dad - but in this case, I believe him. Though the story is very bizarre, she is in custody and unlike other stories, she's not an imaginary nanny, a mysterious armed black man, a group of Hispanics, etc...all the made-up perps often used in cases like these that child-abuser/murderers like to blame. Agree with those that say if he had anything to do with it, why immediately point the finger at his accomplice? Best to wait a few days, even till evening, to make sure the exchange went down, then to call police and make up a more plausible "she wandered off" story.
