PHOENIX (AP) — A psychological report released Thursday warned that while Jared Lee Loughner was competent to plead guilty in the Tucson mass shooting, he remained severely mentally ill and his mental condition could deteriorate under the stress of a trial.

The report was prepared in late April by a federal Bureau of Prisons psychologist who testified in court Tuesday before a judge allowed Loughner to plead guilty in the January 2011 mass shooting.
