• Lopez joined the U.S. Army in 2008, served in the tail-end of the Iraq War twice, saw no direct combat experience, was not injured and didn't appear to have any connection to extremist groups, according to Army Secretary John McHugh.
• McHugh said Lopez had been examined by a psychiatrist who found no violent or suicidal tendencies. The soldier had been prescribed Ambien to deal with a sleeping problem.
• He joined the National Guard in Puerto Rico in 1999. Nine years later, he enlisted in the Army as an infantry soldier but later became a truck driver.
• Lopez was married and one young child. Just over a week ago, the family moved to an apartment complex not far from the Ft. Hood grounds.
