Lynn and Sgt. Milton Ortiz, Jr., both of the 1st Battalion, 109th Infantry (Mechanized) of the Pennsylvania National Guard, were each charged with one count of obstructing justice for allegedly conspiring with another soldier who allegedly put an AK-47 near the body of the man in an attempt to make it look as though he was an insurgent.

Ortiz also was charged with one count of assault and one count of communicating a threat for a separate incident on March 8 when he allegedly placed an unloaded weapon against the head of an Iraqi man and threatened to send him to prison, the military said.

Both soldiers are being held in Baghdad while awaiting Article 32 hearings to determine if there is sufficient evidence to proceed to a court-martial.
