What kind of tests did the military do on Sgt. Russell?

Sgt. Russell had been in the military most of his life. Third tour plus two before this in other countries. It is not as if he is new to any of this. If he had problems we need to find out what kind of tests were done and if the tests sent an already stressed out career soldier over the edge or not. If they did, then how many others were sent over the edge as well?

Base Slayings Spur Probe of Mental Health Care

BAGHDAD, May 12 -- The U.S. military said Tuesday that it is launching a probe to identify shortcomings in mental health treatment for troops deployed in war zones, after a soldier allegedly killed five fellow service members at a base clinic in Baghdad on Monday.

Military police officers took Russell into custody outside the clinic shortly after the shooting.

Perkins said Army criminal investigators are putting together a timeline of the events leading up to the shootings. He said he was not aware of a motive and did not know whether Russell knew any of the slain troops.

Russell's father, Wilburn Russell, 73, told the Associated Press on Tuesday that counselors at the clinic "broke" his son, by putting him through stressful mental tests but not clarifying that they were merely tests. The elder Russell said his son had e-mailed his wife sometime before the shooting and told her he had had two of the worst days in his life. He told her that "his life was over as far as he was concerned," the father said. Wilburn Russell said his son was not a violent man.
