She MADE UP a person.
If I said Sasquatch borrowed my car and drove it all over your landscaping are you saying I should skate on the charges because you can't prove Sasquatch DIDNT do it?
That's beyond ignorant.
Sasquatch is a tad bit of a hyperbole. Now Steve? That's possible. And when there's no evidence to suggest that you, instead of Steve, did something with your car? Then yes, that is what we call "reasonable doubt."
Unless, of course, your fingerprints and DNA are all over the car, you don't have an alibi, and eye witnesses place you as the driver of the car. But, when there's no DNA, no eye witnesses, and no cause of death, you can't go convicting people of murder. Or manslaughter. Or criminal negligence that resulted in someone's death. It just doesn't work that way.
What's ignorant is wanting to convict someone of murder because they partied while their child was missing. You don't agree with her actions that she makes in the wake of her child's disappearance? Awesome, but that doesn't affect the fact that there wasn't enough evidence to convict her of murder or manslaughter. You think she's a big skankopotamus with no conscience? Great for you, but that's not evidence of her being the cause of her daughter's death.
