Six years removed from the death of their son - former NFL star Pat Tillman - in Afghanistan, Patrick and Mary Tillman say they haven't gotten the full truth from the U.S. Army and don't expect to.
"No, we don't know the whole truth," Mary Tillman said on CNN's "Larry King Live" Monday night. "They never did a criminal investigation after Pat was killed. So, without that proper criminal investigation, they destroyed evidence, which is long gone. There really is no way for us to know exactly what happened to him."
