Suicide Epidemic Among Veterans

They are the casualties of wars you don't often hear about - soldiers who die of self-inflicted wounds. Little is known about the true scope of suicides among those who have served in the military.

But a five-month CBS News investigation discovered data that shows a startling rate of suicide, what some call a hidden epidemic, Chief Investigative Reporter Armen Keteyian reports exclusively.

"I just felt like this silent scream inside of me," said Jessica Harrell, the sister of a soldier who took his own life.

"I opened up the door and there he was," recalled Mike Bowman, the father of an Army reservist.

"I saw the hose double looped around his neck," said Kevin Lucey, another military father.

"He was gone," said Mia Sagahon, whose soldier boyfriend committed suicide.

Keteyian spoke with the families of five former soldiers who each served in Iraq - only to die battling an enemy they could not conquer. Their loved ones are now speaking out in their names.
