A United States soldier enters the III Corps and Fort Hood Spiritual Fitness Center at the Fort Hood Army Post in Fort Hood, Texas November 7, 2009. Investigators searched on Friday for the motive behind a mass shooting at a sprawling U.S. Army base in Texas, in which an Army psychiatrist trained to treat war wounded is suspected of killing 13 people. The suspected gunman, Major Nidal Malik Hasan, a Muslim born in the United States of immigrant parents, was shot four times by police, a base spokesman said.
