The suspect in the Tucson shooting rampage has been transported from Missouri to Arizona so a judge can consider whether he’s mentally fit to stand trial.

If not, Jared Lee Loughner will return to the federal prison in Springfield to extend his stay by another eight months.

Loughner has pleaded not guilty to 49 charges stemming from the Jan. 8 shooting that killed six and injured 13, including Representative Gabrielle Giffords.

Loughner’s attorneys have filed an injunction saying the Springfield prison’s forced medication of Loughner has NOT proven there’s a substantial probability his condition can be improved so that he can stand trial.
