Tragedy at Fort Hood: The Victims

A civilian employee at Fort Hood, Michael Grant Cahill is shown with his grandson Brody; he was among the 13 killed during the shootings at the Texas Army base Thursday, Nov. 5, 2009. The 62-year-old physician's assistant suffered a heart attack two weeks ago and returned to work at the base as a civilian employee after taking just one week off for recovery. His daughter Keely Vanacker, her words bare with shock and disbelief, said, "He survived that. He was getting back on track, and he gets killed by a gunman." (Keely Vanacker/AP Photo)
