Federal Judge Larry A. Burns ruled today that Jared Lee Loughner, the man charged with the shootings of Jan. 8, is incompetent to stand trial.

This ruling effectively halts the criminal case against Loughner, pending re-examination in four months. Loughner is charged with 49 criminal counts stemming from the shooting spree that killed six and wounded 13, including Rep. Gabrielle Giffords.

In reaching his decision, Burns reviewed mental health evaluations of Loughner by two mental health experts.

The ruling also stonewalls additional state charges that Loughner faces, as state authorities are unable to proceed with their case until after the conclusion of federal proceedings.

Burns ordered Loughner’s case delayed until he is rehabilitated to a point where he can understand the charges against him and assist in his own defense.

Loughner will be hospitalized at a federal facility for four months to undergo treatment. His competency will be re-evaluated at that time.
