The 34-year-old soldier who went on a shooting rampage at Fort Hood, Tex., argued with members of his unit over an application for a leave of absence, witnesses said. Spec. Ivan A. Lopez had been undergoing treatment for depression and had seen a psychiatrist last month, but Army officials said they had not considered him a threat.

Jeff Miller lights four candles, one for each of the people killed in the Fort Hood shooting, including the gunman, at the beginning of the worship service at First United Methodist Church in Killeen, Tex. Investigators say that an Army truck driver, Spec. Ivan A. Lopez, had an argument before opening fire at the Texas post on April 2, killing three soldiers, wounding 16 and then taking his own life.
