Eight U.S. soldiers have been charged in the death of 19-year-old Private Danny Chen, who was found shot to death in a guard tower in southern Afghanistan. It was first thought to have been a suicide, but the military's investigation found that the Asian-American had been the target of ethnic slurs and physical attacks by his fellow soldiers. Chen was found dead Oct. 3 with a gunshot wound below the chin; it's not clear from the charges whether the eight soldiers are accused of killing him or whether officials are alleging that their mistreatment of Chen led him to take his own life.
