Did army special forces pump Sergeant Robert Bales with steroids before he killed 16 Afghan civilians in March 2012?
According to his attorney, that's what he plans to argue at the penalty phase of his trial.
Bales has agreed to plead guilty next week to avoid the death penalty.And in an effort to avoid a life sentence, his defense will also argue the army knew he was suffering from post traumatic stress and a traumatic brain injury when they sent him to Afghanistan.
