CAMP PENDLETON, Calif. (AP) — A Marine sergeant accused of murdering an unarmed Iraqi captive during heavy fighting in Fallujah in 2004 was heard on tape Thursday telling how his squad argued over what to do with their prisoners and saying he "did one guy" as they sought to keep up with their unit.

The recording played by military prosecutors was made when Sgt. Ryan Weemer, 25, was applying for a job with the U.S. Secret Service. It was played at the start of an Article 32 hearing, at which investigating officer Maj. Glen Hines will determine whether there is enough evidence to support a court-martial, or military trial.

In the interview, Weemer said he and other squad members killed four unarmed Iraqis they were holding in a boarded-up house because they didn't have time to take the men to a jail.
