Afghan massacre suspect's wife: 'He would not do that'

Robert Bales, the U.S soldier charged with killing 17 Afghan civilians, loves children and would not have committed the murders he is accused of, his wife said.

"It's unbelievable to me," Karilyn Bales said of the charge that her husband killed nine children and eight adults.

"I have no idea what happened, but he would not -- he loves children, and he would not do that," she told NBC News in an interview, excerpts of which aired Sunday and Monday.
