TUCSON, Ariz. (AP) The man who pleaded guilty to a deadly Arizona shooting rampage that also wounded former U.S. Rep. Gabrielle Giffords and 12 others has declined to speak at his sentencing.

Jared Lee Loughner has told a judge in Tucson, Ariz., that he will not be speaking at a hearing Thursday where the 24-year-old is expected to be sentenced to life in prison.

Loughner wore dress pants and a dark brown shirt with a tie, and drank from a foam cup, as he awaited statements from victims of the January 2011 attack.

Giffords and her astronaut husband, Mark Kelly, were in attendance as were Loughner's parents.

Loughner had pleaded guilty to 19 federal charges under a plea agreement.
