A military jury on Monday acquitted a sergeant on the most serious charges in the death of Pvt. Danny Chen, a Chinese-American from Manhattan who killed himself last year while deployed in Afghanistan, but found him guilty on lesser charges... The jury determined that the sergeant, Adam M. Holcomb, was not guilty of negligent homicide, reckless endangerment, communicating a threat and hazing. Sergeant Holcomb was convicted on two counts of maltreatment and one count of assault consummated by battery.
