As I recall, Schiavo's lawyers actually applied to the court for immediate cremation. That's like standing on the courthouse steps and yelling for the cameras, "If we don't destroy the evidence fast, they could get us for Murder One!"
Unfortunately for Felos and Bushnell, immediate cremation was too illegal even for Greer. So, the autopsy was performed and when it was over, the bulimia theory -- Michael's only alibi -- was gone.
"applied to the court for immediate cremation"
Didn't they also ask for money in Terri's fund to pay for the cremation?
