The lawyer for the Army sergeant accused of slaughtering 16 Afghan civilians met with his client behind bars for the first time to begin building a defense and said the soldier gave a powerfully moving account of what it is like to be on the ground in Afghanistan.

Lawyer John Henry Browne said he and Robert Bales, who is being held in an isolated cell at the military prison, met for more than three hours in the morning at Fort Leavenworth. Browne, co-counsel Emma Scanlan and Bales were expected to talk again in the afternoon.

"What's going on on the ground in Afghanistan, you read about it. I read about it. But it's totally different when you hear about it from somebody who's been there," Browne told The Associated Press by telephone during a lunch break. "It's just really emotional."

Bales, 38, has not been charged yet in the March 11 shootings, which sparked protests in Afghanistan, endangered relations between the two countries and threatened to upend American policy over the decade-old war. Formal charges could be filed within a week.

Browne, a Seattle attorney who defended serial killer Ted Bundy and a thief known as the "Barefoot Bandit," has said he has handled three or four military cases. The defense team includes a military defense lawyer, Maj. Thomas Hurley.

At their meeting, Browne said Bales clarified a story, provided initially by the soldier's family, about the timing of a roadside bomb that blew off the leg of one of Bales' friends. It was two days before the shooting, not one, and Bales didn't see the explosion, just the aftermath, Browne said.

The details of the blast could not be immediately confirmed.

Military officials have said that Bales, after drinking on a southern Afghanistan base, crept away to two villages overnight, shooting his victims and setting many of them on fire. Nine of the dead were children and 11 belonged to one family.

Bales arrived at Fort Leavenworth last Friday and is being held in the same prison as other prominent defendants. Pfc. Bradley Manning, who is charged with leaking classified documents to the WikiLeaks website, has been held there on occasion as he awaited trial.

Bales is "already being integrated into the normal pretrial confinement routine," post spokeswoman Rebecca Steed said.

That includes recreation, meals and cleaning the area where he is living. Steed said once his meetings with his attorneys are complete later in the week, Bales will resume the normal integration process.

Bales' family said through his defense lawyers over the weekend that they are stunned by the accusations, but are standing by a man they knew "as a devoted husband, father and dedicated member of the armed services."

Court records and interviews show that Bales had commendations for good conduct after four tours in Iraq and Afghanistan. He enlisted in the military after the Sept. 11 terrorist attacks.

He also faced a number of troubles in recent years: A Florida investment job went sour, his Seattle-area home was condemned as he struggled to make payments on another, and he failed to get a recent promotion.

Legal troubles included charges that he assaulted a girlfriend and, in a hit-and-run accident, ran bleeding in military clothes into the woods, according to court records. He told police he fell asleep at the wheel and paid a fine to get the charges dismissed.

In March 1998, Bales was given a $65 citation for possessing alcohol at Daytona Beach, Florida. He did not pay the fine nor did he defend himself in court. A warrant was issued for his arrest, but it later expired.

If the case goes to court, the trial will be held in the U.S., said a legal expert with the U.S. military familiar with the investigation who spoke on condition of anonymity to discuss the case.

That expert said charges were still being decided and that the location for any trial had not yet been determined. If the suspect is brought to trial, it is possible that Afghan witnesses and victims would be flown to the U.S. to participate, he said.

After their investigation, military attorneys could draft charges and present them to a commander, who then makes a judgment on whether there is probable cause to believe that an offense was committed and that the accused committed it.

That commander then submits the charges to a convening authority, who typically is the commander of the brigade to which the accused is assigned but could be of higher rank.
