Good points.
When trying to come up with all possibilities, sometimes I come up with some wild ideas.
Like: MF wasn't supposed to drive. She had issues with that legally, no? Maybe that's why she had gotten someone to drive when taking the baby?
Also - this is the weirdest thought -
JUST A THOUGHT, so don't flame me, please : What if MF had not actually put Heidi in the trunk
or even known she was there, if someone else had done that, and MF didn't use her car at all? What if MF had done the kidnapping part, not
also wanting to kill her friend? Hard to figure out a disturbed mind, but maybe there was someone else out there who had done the worst part?
Not trying to protect her horrible actions at all - just trying to come up with all possibilities!
