StoryCorps' Military Voices Initiative records stories from members of the U.S. military who served in Iraq and Afghanistan.
After Army Pfc. Brian Orolin returned from Afghanistan in 2011, his wife Donna could tell something wasn't right. He became paranoid and suffered constant headaches, and he would isolate himself in his bedroom with the lights dimmed.
Then, on November 19, Brian left his home, wife and two children in Spring, Texas.
He's been missing ever since.
