福克斯新闻 战争带来的不安 Anxiety combat（在线收听）

Before enlisting in the Army in 2008, 34-year-old Ivan Lopez spent 11 years in the Puerto Rico National Guard.

He spent four months as a truck driver in Iraq, but saw no combat and more recently was treated for depression, anxiety and sleeplessness.

Army Secretary John McHugh says Lopez met with a psychiatrist last month. (McHugh) "We had no indication on the record of that examination that there was any sign of likely violence."

The weapon used was recently purchased, but military rules prohibit carrying private weapons on Post without proper authorization from a commander.

That authority was not given to Lopez.
