Laura's death was considered a homicide and GH was already convicted of first degree murder, so it's not an "accidental" death, nor is that how it's listed on the autopsy report. A stab wound to the neck and other damage to the neck is not considered "accidental." Further, there was no damage seen to Laura's skull to indicate a fall or anything there that would have caused her death.
Homicide to Laura was proven.
Everything around that is then "acting in concert."
Amanda claimed she had no idea Laura's body was in the trailer, nor that Laura was even dead, until she got to TX. That testimony was just soundly impeached by the "accident claim." And Amanda puts herself right there as the death is occurring.
Amanda knew, helped, participated, asked her own sister to participate, got her own daughter involved (to watch the kids).
I hear the slamming of a cell door!
