Last month, Marine Staff Sgt. Travis N. "T-Bo" Twiggs went to the White House with a group of Iraq war veterans called the Wounded Warriors Regiment and met President George W. Bush. Two weeks later after a failed attempt to drive into the Grand Canyon, the 36-year-old Marine and Post Traumatic Stress Disorder sufferer fatally shot his 38-year-old brother, Willard J. "Will" Twiggs, and then killed himself.
