I agree with everything you say,
but, I think deep down inside you've already answered your own questions. I have the same questions, yet I know what the answers are as you most likely do too. Anyone that would take a life and go through all he did to hide it, most likely doesnt care how his babies live for the rest of their lives. There's so many other ways he could have been a free man, but, evil is evil and he did what evil does.
How I wish Monica would have reached out more or left to a safe place. But, she's like any woman , as myself was at her age,
and really didnt believe how dangerous he was and is.
We always believe there's light at the end of a dark tunnel, especially when we make progress in our lives as Moni was doing and I guess that's one of the most dangerous times, because the other person sees how strong you are and is threatened by it.
Moni was well on her way to being able to take care of her babies and he knew that. He gave no $h!t what happened to THE babies, he saw the road ahead where he would be made to pay child support and most likely one more as it has been said that Moni may have been pregnant.
I don't think he will ever admit to where Moni is. I just hope this case can move forward without her body, as I feel they have enough evidence to arrest.
God bless the babies and Monis family that loved her and want her home!!
