The opposing attorneys do battle with expert wits in a way that really highlights the entire legal adversary process in the US CJ system. The degree of physical impairment from the cervical injury is well described. The timeline of where and when the injury occurred is a point of major disagreement. The defense is claiming an accident occurred (therefore no homicide). The prosecutor argues “malice” and/or “disregard for human life” which is the prima facie case for a murder charge.
