The wife of Staff Sgt. Robert Bales describes the accusations against her husband as 'unbelievable.'

Karilyn Bales says she doesn’t believe her husband was involved in the cold-blooded killings of 17 Afghan villagers, including children, going so far as to say that nothing could change her mind that this is not what it appears to be.

Military officials say Bales walked off his base in southern Afghanistan earlier this month, twice on that fateful night, and killed eight adults and nine children before returning to the base where he surrendered.

If the numbers seem to have increased, they did.

"There is a - there was an increase in the number of what we believe to have been those who were killed tragically in this event,' explained Gen. John Allen, ISAF Commander, 'but the number increased was based upon the initial reporting by the Afghans and so we should not be surprised that, in fact, as the investigation went forward that an additional number was added to that. That is something that something we understand and we accept and as the investigation goes forward we'll get greater clarity on that." 

The US is reported to have paid $860,000 to the families of the victims. And Karilyn Bales has set up a legal defense fund for her husband who could face the death penalty if convicted.
