Cremate the bodies, hide the autopsy reports...
I assume the courtroom will be banned to outsiders too - assuming there is a trial.
What was on the bodies that they didn't want anyone to see?
Probably too gruesome to be publicly available..........
Good question.
My guess is that provocative toxicology screens may be pending as to the victims and the defendant. If so, with the support of the family, the police and defense would want to investigate and assess the facts before announcing any findings.
