Yes, she was cremated. She was cremated too quickly at the request of the family.. not even a wake, albeit the casket would have been closed because of her "condition".
No second chance for an autopsey..DNA..or anything.
In fact, Feldman and company requested to be allowed into the Van Dam house before the trial, and Damon and Brenda turned them down by saying "We don't want EVIL in our home again"...that's that!
