>> gregg: grisly testimony presented at the casey anthony murder trial as prosecutors try to build their case against her and really important witness, the county medical examiner. saying it is clear to her the manner of death is homicide. >> by my experience and by what is known about the way homicides occur, not reporting that child missing the fact it is tossed into a field to rot in bags is a clear indication that the body was trying to be hidden, those are -- even being put in a bag is a very big red flag for homicide and, i've never seen that with an accidental death of a child and the fact there is duct tape anywhere attached to that child's face, is to me indication of a homicide. >> gregg: let's bring back our legal panel, joey and anna.
