Loughner will likely be indicted in federal court on several other charges stemming from the attack, including two federal murder counts for the deaths of Roll and Giffords aide Gabriel Zimmerman.

Then it's the state's turn. Loughner is facing a slew of other state charges that have not yet been filed. Federal statute requires the suspension of all state or local prosecutions while the federal case is pending, so state charges will be put on hold until the feds finish their case, the U.S. Attorney's Office and the Pima County Attorney's Office announced earlier this month.

Federal Judge Larry Burns noted in his order that new federal charges are expected to be filed against Loughner before his next court hearing, which is scheduled for March 9.

Burns told attorneys that during the March 9, hearing he would also schedule future hearings and the set a date for trial.
