The Army has postponed a court martial in Washington state for a soldier accused of using drugs, beating up a whistleblower and stabbing a corpse in Afghanistan.

Officials say Tuesday's proceedings at Joint Base Lewis-McChord have been canceled by an undisclosed legal issue. No new date was announced.

Spc. Corey Moore, of Redondo Beach, Calif., is accused of drug use and beating a soldier who was a witness in a drug investigation. He's also accused of stabbing a corpse a platoon found while investigating a helicopter strike.

He could face a dishonorable discharge and more than 11 years in prison if convicted.

Moore is one of a dozen 5th Stryker Brigade soldiers accused of crimes in Afghanistan. Five are charged with murder in the deaths of three Afghan civilians.
