Army Staff Sgt. Robert Bales, the American soldier allegedly responsible for killing 16 Afghan civilians last week, is expected to be formally charged as early as Saturday. His lawyer, John Henry Browne, has a history of working with high-profile clients including serial killer Ted Bundy. Bales, 38, arrived late Friday night at a military prison in Fort Leavenworth, Kans., after being identified Friday. U.S. officials said he won’t necessarily be tried in the U.S., as the Afghan government is demanding court proceedings be held in Afghanistan. Officials have said that Bales, a married father of two, he has a clean record and neighbors describe him as a family man and good guy. He had been deployed to Iraq three times where he suffered a traumatic brain injury before he was sent to Afghanistan.
