Army Pfc. Naser Jason Abdo's attorneys filed motions Thursday in federal court in Waco. One seeks to toss out any evidence obtained when he was arrested last summer.
The Killeen Daily Herald reports that Abdo's attorneys claim investigators denied him access to an attorney and did not read him his Miranda rights before he confessed.
Abdo was AWOL from Fort Campbell, Ky., when he was arrested in July at a Killeen motel near the Texas Army post.
Abdo faces up to life in prison if convicted of attempting to use a weapon of mass destruction and eight other charges. His federal trial is set for May.
