Frie was innocent.
I suspect the best friend was killed by the dad.
I suspect her daughter was killed by her ex or the girlfriend's mom.
Brie didn't show any jealously in the earlier videos with the best friend.
She also had no motive to harm her child yet she wanted custody of so bad...doesn't make sense why she would harm her child out of jealousy.
Waiting for season 2, it better be a continuation of this case.
