A former Army private accused in the horrific rape and killing of a young Iraqi woman and the execution-style slaying of her family had been discharged because of an "antisocial personality disorder," U.S. military officials told The Associated Press.

Investigators say Steven D. Green and other soldiers from the 101st Airborne Division plotted to rape a young Iraqi woman they first saw at a traffic checkpoint in the village of Mahmoudiya. Green is accused of rounding up three family members in a room of the woman's house and shooting them before raping and killing her.

Previously, in a federal court affidavit, investigators said only that the 21-year-old Green had been given an honorable discharge for a "personality disorder" this spring before the March murder case came to light.

But U.S. military officials who spoke to the AP on condition of anonymity because of the sensitivity of the case said late Tuesday it was an "antisocial personality disorder." They did not elaborate.

In the West Texas town of Midland where Green grew up, few people offered details of his life.

Green's father, John, told the AP that attorneys have advised him not to publicly talk about the case against his son, who was charged with rape and four counts of murder Monday in a federal courtroom in Charlotte, N.C.

But one resident — a former Marine — hoped the accusations against Green don't reflect poorly on the soldiers still serving in Iraq.

"I don't care where he's from; this gives us a black eye," said Shaun Sanders, who spent 14 months in the Middle East and Africa and now lives in the building by Green's family but did not know him. "To hear a story of something like this happen in this particular region, at this particular time, is not good."

Greg Simolke told The Washington Post that his nephew had visited relatives in North Carolina last week on his way to and from a funeral at Arlington National Cemetery for a member of his platoon who was killed in Iraq. Click here to read The Washington Post's story.

"When he was here for this visit, he seemed like the same old Steve," Simolke told the Post. "I don't understand what happens in a war, so I don't know how these things happen."

Relatives told the newspaper that Green had grown up in Midland and joined the Army after receiving his GED. He went to Fort Benning, Ga., for infantry training and graduated in June 2005, his family said.

"He had found direction in his life, something important and something that he really wanted to do," Simolke told the Post. "He was talking about making the military his career and was ready to go to Iraq. He thought it was a good thing to be serving his country."

Green was arrested Friday at a relative's home in Marion, about 75 miles northwest of Charlotte, but authorities wouldn't disclose the relative's name. Mary Simolke, Green's grandmother who lives near Marion, declined comment.

According to an affidavit, the funeral Green was attending in Arlington was for one of the two soldiers whose mutilated bodies were found June 19, three days after they were abducted by insurgents near Youssifiyah, southwest of Baghdad.
