Victims set to come face-to-face with Giffords' gunman at sentencing Mamta Popat / Pool / EPA Mourning continues after a tragedy where 22-year-old Jared Lee Loughner attempted to assassinate U.S. congresswoman Gabrielle Giffords in a shooting that killed six people and wounded 14. TUCSON, Ariz. -- The man who pleaded guilty in the Arizona shooting rampage will be sentenced Thursday for the attack that left six people dead and wounded former U.S. Rep. Gabrielle Giffords and 12 others. The sentencing hearing will mark the first time that victims will confront Jared Lee Loughner in court about the January 2011 shooting at a Giffords political event outside a grocery store in Tucson, Ariz. Prosecutors say an unspecified number of victims will comment before U.S. District Judge Larry Burns sentences Loughner, though it's unknown whether Giffords or her husband plan to attend or have a statement read on their behalf. Three shooting victims have told The Associated Press that they intend to comment at the hearing. Citing a source close to the family, Politico reported Wednesday that Giffords and husband Mark Kelly were expected to appear in court. The 24-year-old had pleaded guilty three months ago to 19 federal charges under an agreement that guarantees he will spend the rest of his life in prison without the possibility of parole. The deal calls for the dismissal of 30 other charges and a sentence of seven consecutive life terms, followed by 140 years in prison. Jared Lee Loughner will spend the rest of his life in jail for killing six people and wounding others, including then-Congresswoman Gabby Giffords, during a 2011 shooting rampage in Arizona. Both sides reached the deal after a judge declared that Loughner was able to understand the charges against him. After the shooting, he was diagnosed with schizophrenia and underwent forcible psychotropic drug treatments. Some victims, including Giffords, welcomed the deal as a way to move on. It spared victims and their families from having to go through a potentially lengthy and traumatic trial and locks up the defendant for life. Ron Barber, a former Giffords staffer who was shot in the cheek and thigh during the attack and later won election to her seat when Giffords stepped down, plans to make a statement, said his spokesman, Mark Kimble.

Suzi Hileman, who was shot three times while trying to save her 9-year-old neighbor, and Mavy Stoddard, whose husband died shielding her from bullets, plan to address the court. "He has to pay the consequences for what he did, and justice will be served," Hileman said. Judy Clarke, Loughner's lead attorney, didn't return messages seeking comment.

Christina Pietz, the court-appointed psychologist who treated Loughner, had warned that although Loughner was competent to plead guilty, he remained severely mentally ill and his condition could deteriorate under the stress of a trial. When Loughner first arrived at a Missouri prison facility for treatment, he was convinced Giffords was dead, even though he was shown a video of the shooting, but eventually realized she was alive after he was forcibly medicated. 'Home for good': Giffords, husband move back to Tucson It's unknown whether Pima County prosecutors, who have discretion on whether to seek the death penalty against Loughner, will file state charges against him. Stephanie Coronado, a spokeswoman for Pima County Attorney Barbara LaWall, said Wednesday that no decision had been made. John Leonardo, the US Attorney for the District of Arizona, says "Today justice was done," because Jared Loughner "will spend the rest of his life in prison." Watch the entire news conference. It's unclear where Loughner will be sent to serve his federal sentence. He could return to a prison medical facility like the one in Springfield, Mo., where he's been treated for more than a year. Or he could end up in a prison such as the federal lockup in Florence, Colo., that houses some of the country's most notorious criminals, including Oklahoma City bombing conspirator Terry Nichols and "Unabomber" Ted Kaczynski. The exact placement will depend on the nature of his mental illness and its treatment.
