FORT BRAGG, N.C. — 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.

Prosecutors had sought to convince the jury that Sergeant Holcomb’s treatment of Private Chen, which the prosecutors said included hazing and racial taunts, led directly to his suicide.

The 10-member jury of Army officers and enlisted soldiers reached its verdict after about two hours of deliberations on Monday afternoon. The court-martial began last Tuesday. Sergeant Holcomb was one of eight soldiers charged in the case and the first to be tried.
