Fort Hood gunman sought mental health treatment

An Iraq War veteran being treated for mental illness was the gunman who opened fire at Fort Hood, killing three people and wounding 16 others before committing suicide, in an attack on the same Texas military base where more than a dozen people were slain in 2009, authorities said.
Within hours of the the attack, investigators started looking into whether the man's combat experience had caused lingering psychological trauma.
Fort Hood's senior officer, Lt Gen Mark Milley, said the gunman had sought help for depression, anxiety and other problems.
Among the possibilities investigators planned to explore was whether a fight or argument on the base triggered the attack.

"We have to find all those witnesses, the witnesses to every one of those shootings, and find out what his actions were, and what was said to the victims," said a federal law enforcement official who spoke on condition of anonymity, because he was not authorised to discuss the case by name.
The official said authorities would begin by speaking with the man's wife, and expected to search his home and any computers he owned.
The shooter was identified as Ivan Lopez by Texas Representative Michael McCaul, chairman of the House Homeland Security Committee. But the congressman offered no other details, and the military declined to identify the gunman until his family members had been notified.
