Jared Loughner, the man who killed six people and wounded 13 – including Gabrielle Giffords – in a 2011 shooting spree
outside of a Tuscon, Ariz., grocery store, was sentenced on Thursday to seven consecutive life terms and 140 years in prison without parole.
"Her life has been forever changed ... immeasurably altered," Giffords's husband, retired astronaut, Mark Kelly, said in court on Thursday with his wife by his side. "Every day is a continual struggle to do those things she was once so ... good at."
Giffords suffered a single gunshot wound through the brain
. Although news reports at the time initially indicated the shot may have been fatal, the congresswoman survived and underwent surgery at the University Medical Center in Tucson.
On Thursday, U.S. District Judge Larry Burns said that six of Loughner's life sentences represent the six slain victims, and one represents the attempted assassination of Giffords, according to CNN
Loughner, 24, who didn't make any statements, reportedly entered the courtroom wearing a brown, striped shirt and had a short haircut. Showing no emotion, he looked at the other victims as his mother sobbed nearby.
"Mr. Loughner, you may have put a bullet through her head, but you have not put a dent in her spirit, and her [ability to do good]," Kelly said.
Following the tragedy, Giffords's ability to speak has lessened, she's blind in one eye and she struggles to walk, according to CBS News
