Staff Sgt. Robert Bales, named as the suspect who allegedly went on a rampage, killing 16 Afghan civilians, was remembered by his neighbors in Lake Tapp, Wash., as a family man and "good guy," but news of a criminal record has surfaced and his wife's blog posts reveal a man frustrated with not being promoted.
Between the 38-year-old's deployments, he had scattered trouble at home, including a criminal record that includes a misdemeanor arrest for assaulting a girlfriend in 2002 that led to 20 hours of court-ordered anger management, and a report of a drunk driving arrest in 2005 for which he wasn't charged.
His record also includes a hit-and-run in 2008. Witnesses saw a bleeding man in a military-style uniform with a shaved head running into the woods, where the police found him. Bales said he fell asleep at the wheel, and paid about $1,000 in fines and restitution, according to The Associated Press. The case was dismissed.
Bales' wife, Karilyn Bales, a public relations and marketing manager, wrote on her blog in March of last year that her husband was very disappointed about not getting promoted to E-7, sergeant first class.
"Bob didn't get a promotion and is very disappointed, after all the sacrifices he has made for his love of country. But I am also relieved. We can finally move on to the next phase of our lives," she wrote.
The Bales' house was recently listed for sale, and his wife wrote that they hope to move closer to family in the Midwest.
He Was 'One of the Best Soldiers I Ever Worked With'
Neighbors painted a picture of the career soldier as a family man who spoke little about his deployments.
"I just can't believe Bob's the guy who did this," neighbor Paul Wohlberg told the Associated Press. "A good guy got put in the wrong place at the wrong time."
Kassie Holland, a neighbor, told the Associated Press that she would see Bales playing with his daughter Quincy, 4, and son Bobby, 3.
"My reaction is that I'm shocked," she said. "I can't believe it was him. There were no signs. ... He always had a good attitude about being in the service. He was never really angry about it. When I heard him talk, he said, it seemed like, 'Yeah, that's my job. That's what I do.' He never expressed a lot of emotion toward it."
Bales' platoon leader in Iraq described him to the Washington Post as an exemplary soldier who "saved many a life."
"Bales is still, hands down, one of the best soldiers I ever worked with," Army Capt. Chris Alexander , 28, told the newspaper.
Bales remains locked up today in Fort Leavenworth, Kan., where he is being housed in a private cell away from other inmates.
Charges are expected soon against the career soldier, who was flown out of Afghanistan and arrived at the Army prison Friday night.
Bales is accused of breaking into several Afghan homes in the middle of the night last Sunday and killing 16 civilians, mostly women and children. He could face the death penalty if found guilty.
Pentagon officials said that Bales' being brought back to the U.S. does not necessarily mean that his military court proceedings will be held in the U.S., holding out the possibility that they could be held in Afghanistan. The Afghan government is demanding that Bales be tried in Afghanistan.
Details of Bales' military record have also emerged and they depict a soldier who has seen intense combat and lost part of a foot.
Bales, who enlisted shortly after the 9/11 terror attacks, was first deployed in November 2003 when his unit spent a year in Mosul, Iraq.
In June 2006, he and his unit were sent back to Iraq and their year-long deployment was given a three-month extension until September 2007. During that time, he saw duty in Mosul in the north, Bagdad when the city was pressed by militants, and then Baquba, where his unit took major casualties.
His final Iraq deployment was from September 2009 to September 2010 in Diyala province, which was also a hotbed of insurgent activity.
In December 2011, he was ordered to Afghanistan.
Bales' alleged murderous rage stood in stark contrast to what he said after a fierce battle in Zarqa, Iraq, in 2007.
"I've never been more proud to be a part of this unit than that day for the simple fact that we discriminated between the bad guys and the noncombatants and then, afterward, we ended up helping the people that three or four hours before were trying to kill us," he told Fort Lewis' Northwest Guardian.
"I think that's the real difference between being an American as opposed to being a bad guy, someone who puts his family in harm's way like that," Bales said at the time.
John Henry Browne, Bales' lawyer in Seattle, told The Associated Press Thursday that the soldier had witnessed his friend's leg blown off the day before the massacre.
Bales reportedly spent his entire 11-year career at Joint Base Lewis-McChord in Washington state and lived not too far from the base. Originally from the Midwest, he was deployed with the Second Battalion, 3rd Infantry Regiment of the 3rd Stryker Brigade, 2nd Infantry Division in December.
Browne said that he was highly decorated and had once been nominated for a Bronze Star though he did not receive it. He also lost part of a foot because of a combat injury.
"He's never said anything antagonistic about Muslims. He's in general very mild-mannered," Browne told the AP.
Bales reportedly left Camp Belambay -- where he was stationed to protect Special Operation Forces creating local militias -- in the middle of the night, wearing night-vision goggles, according to a source. The shooting occurred at 3 a.m. in three houses in two villages in the Panjway district of southern Kandahar province.
In the first village, more than a mile south of the base, he allegedly killed four people in the first house. In the second house, he allegedly killed 11 family members -- four girls, four boys and three adults.
According to a member of the Afghan investigation team and ABC News' interviews, he then walked back to another village past his base and killed one more person. He reportedly returned to the base on his own and turned himself in calmly.
An official told ABC News that the soldier had suffered a mild traumatic brain injury (TBI) in the past, either from hitting his head on the hatch of a vehicle or in a car accident. He reportedly went through the advanced TBI treatment at Fort Lewis and was deemed to be fine.
He also underwent mental health screening necessary to become a sniper and passed in 2008. He had routine behavioral health screening after that and was cleared, the official said.
When the soldier returned from his last deployment in Iraq he had difficulty reintegrating, including marital problems, the source told ABC News. But officials concluded that he had worked through those issues before deploying to Afghanistan.
On Thursday, Browne said that Bales' marriage was "fabulous."
Afghan political leaders have called for Bales to be tried publicly in Afghan courts, but U.S. military officials said the case will be handled in U.S. military courts. A U.S. military official said Afghan officials were made aware of Bales' transfer out of Afghanistan before it occurred.
