Tucson shooting massacre, one year later

Posted: Updated:

TUCSON, Ariz. -- Sunday marks the first anniversary of the shooting massacre in Tucson that ended with six deaths and 13 wounded, including Congresswoman Gabrielle Giffords.

A number of events are planned to honor those wounded in the Jan. 8, 2011 shooting. Giffords, who has been making an incredible recovery, and her husband, retired Navy captain and astronaut Mark Kelly, will attend a vigil at the University of Arizona on Sunday.

Ron Barber, who was wounded in the mass shooting is slated to speak at the event.

Suspected shooter Jared Loughner, 23, has been the center of a variety of legal wranglings in the year since the massacre. He has pleaded not guilty to 49 charges.

The case was put on hold when Loughner was diagnosed with schizophrenia and found psychologically unfit to stand trial. Despite protests by his defense team, Loughner is being forcibly medicated in an effort to control his mental illness and render him fit for trial.
