An Indiana National Guard (search) soldier accused of murdering an Iraqi police officer will be court-martialed, the Army announced Friday.

Cpl. Dustin Berg, 21, is accused of killing Hussein Kamel Hadi Dawood Al-Dubeidi south of Baghdad in November 2003, then shooting himself. Berg, of Ferdinand, Ind., received a Purple Heart (search) for wounds sustained in the incident.

An investigator testified during an Article 32 hearing last month that Berg changed his story multiple times before admitting he killed the police officer. Special agent Clarence Joubert of the Army Criminal Investigative Division said Berg initially said he was shot by a man in a red turban and white shirt.

Berg's attorney said at the hearing, which is similar to a civilian grand jury hearing, that his client acted in self-defense.

Maj. Gen. Terry Tucker, the commanding general at Fort Knox (search), determined that sufficient evidence exists for the case to move forward, public affairs officer Connie Shaffery said. A date for the court-martial has not been set.

Berg is charged with murder, false swearing and the wearing of an unauthorized award.

Berg received a Purple Heart during a ceremony in February 2004, the month he returned home from Iraq. The Indiana National Guard has declined to release the citation describing why the Purple Heart was awarded to Berg.
