This young, pregnant woman did not walk out of her house with 2 little ones, with just the clothes on their backs, no wallet, no phone, no car to escape a bad marriage. She didn't have to flee with nothing; he was at work and she had all day to pack the car with whatever she would need to be away for however long it would take for him to be served with divorce papers.
No one broke into the house and kidnapped them all.
No one was lurking outside waiting for the garage door to open to grab her and the kids.
No one came to the back of the house with a car and 2 baby seats to help her escape.
If she wanted to leave, she had lots of friends and her NC family to help her and there would be NO reason for her not to contact her family to let them know that she had left, was safe and where she and the kids were.
If you want my opinion, and no one said you did, I am thinking that the last person to see her in her home "disappeared" them all.
