For the last four months, the man accused of a January shooting rampage in Tuscon that killed six people and wounded 13, including Rep. Gabrielle Giffords (D-Ariz.), has been sitting in a prison facility in Missouri because he was deemed mentally unfit for trial.

Now, a U.S. District Judge Larry Burns has ruled that “measurable progress has been made” and that in several months Loughner can be fit to appear in court.

After the ruling was announced in an hours-long hearing Wednesday, psychiatrist Dr. James Ballenger told CNN affiliate KGUN that Loughner is remorseful for his actions.

“He didn't even know what he'd done,” Ballenger said “But now he's remorseful and that is another example of his regaining what makes us human.”

Ballenger also said Loughner is no longer having outbursts, and was able to sit quietly throughout the hearing.

Loughner, 23, could face the death penalty if convicted of the shootings. He has pleaded not guilty to the charges.
