Capt. Douglas Wacker, who has done two combat tours in Iraq, has been a law student at the University of San Diego for three years. The alleged crimes did not occur on military property, but the Marine Corps, with approval from civilian authorities, has taken the lead in investigating the case. After an Article 32 hearing at the Marine Corps Recruit Depot, which is akin to a civilian grand jury, Wacker was ordered to court-martial. An arraignment is set for Wednesday. Along with two counts of rape, one of indecent assault and one of attempted rape, Wacker also is accused of five counts of conduct unbecoming an officer and two of obstruction of justice. No details about the alleged crimes were released.
