A military panel in Kuwait has convicted a U.S. soldier of cruelty and maltreatment in the wake of an investigation into an Army suicide in Iraq.

An Army spokesman said Monday that Staff Sgt. Enoch Chatman, of West Covina, Calif., was convicted Wednesday and sentenced Thursday to three months' confinement, a reduction in rank and a reprimand.

Chatman was one of four soldiers accused of mistreating others in their platoon in Iraq.

The investigation was prompted by the August death of Pvt. Keiffer Wilhelm, who grew up in Willard, Ohio. The military has determined there is no direct evidence the soldiers' misconduct caused Wilhelm's death.

A sergeant was found guilty in November. Charges were dropped against one officer. Another is awaiting trial.
