Investigators say they have no solid information regarding David Passaro. He is the only civilian facing federal charges in the case.
Passaro is accused of beating Abdul Wali with his hands, feet and a large flashlight while he was interrogated for two days at a U.S. base in Afghanistan.
Wali, who was suspected of rocket attacks on the base, later died.
