Desperate to hear firsthand how his brother died, Kevin Tillman repeatedly called his unit in Afghanistan trying to reach Pfc. Bryan O'Neal, the youngest Ranger in the platoon who was with Pat Tillman when he died.
Tillman called eight times before someone agreed to allow O'Neal to talk on the phone, but O'Neal was ordered to keep the friendly fire a secret from Kevin.
"I was appalled that when I was able to actually speak with Kevin, I was ordered not to tell him what happened," O'Neal testified, according to the book.
When the unit returned to the United States, Kevin Tillman was there to greet them and in the ensuing days even worked out with some of the soldiers who had fired on his brother. No one mentioned to Tillman what really had happened back on that Afghan mountain.
Later that day, a senior officer realized the secret couldn't be kept from Tillman forever, and called him in to tell him the truth. The news stunned Tillman. He also was stunned at how casually his comrades had kept the news from him, including those who had killed his brother.
"I did my PT [physical therapy] with two of the people who killed Pat and then went to breakfast with the P.L. [platoon leader] who eventually got fired, telling him, 'Hey, you did a good job out there,' not having a clue what really went on," Kevin Tillman later testified at one of the seven investigations into his brother's death.
Kevin Tillman asked Congress for an investigation into his brother's death because he no longer trusted the generals he served under.
Recapping the string of lies and official reports that called the military's actions "missteps," Kevin Tillman testified, "These are intentional falsehoods that meet the legal definition of fraud. ... These are deliberate acts of deceit."
Despite the betrayal by the Army, Kevin Tillman decided to finish out his enlistment and remained in the Army until July 2005.
In 2008, he published a book about the Iraq war entitled, "The Transparent Pillage."
