I wonder what the extent of Xtina's restrictions are? Is she even allowed to leave the base? Do they have someone by her side 24/7? For all intense purposes, is she in the brig without being in the brig?
Legally I don't think Christina is restricted more than any other marine.
She hasn't even been named a person of interest by LE.
Which doesn't mean she isn't being tailed or that her phones aren't tapped. We know mail in and out is gone over.
Calling her up so she will be on the base keeps Christina safer. She is a key witness if not more.
I would think forcing someone to pack things, write a note, withdraw money from their ATM and buy a bus ticket would be taking a lot of chances and eating up a lot of time.
I don't know how CL knew he would have time to lure Maria to his house, wait for her to get there, do all of the things in the above paragraph plus get back to his house with Maria, murder her and clean up the mess and clothes before his wife got home. He had to have planned it in advance.
But, how did he know his wife wouldn't get impatient waiting for him and go home?
I am not saying it isn't possible.
But, I think more likely than not, that there was some mess left when Christina got home.
Personally, I think Christina was in on the clean-up. I think a lot of people's first instinct is to preserve their family and to protect a loved one, no matter how heinious of an act their loved one has committed. You can't be on a crime board without seeing how people rally to stand by family members even when there is overwhelming evidence of that family member's guilt.
BUT, thinking Christina probably helped with the cleaning isn't proof. I think LE made a deal with her because there isn't evidence of Christina's participation and so they could get the goods on Cesar Laurean A.S.A.P.
