Spitz stated that he was not allowed to attend Garavaglia's initial autopsy on Caylee's remains, and that, from his own follow-up autopsy, he was not comfortable ruling the child's death a homicide. He said he could not determine what Caylee's manner of death was, but said that there was no indication to him that she was murdered. Additionally, Spitz testified that he believed the duct tape found on Caylee's skull was placed there after the body decomposed, opining that if tape was placed on the skin, there should have been DNA left on it, and suggested that someone may have staged some of the crime scene photos.
