The U.S. General Services Administration announced that several Arizona officials, including Sen. John McCain and Rep. Ron Barber, are scheduled to attend a ceremony Thursday at the John M. Roll U.S. Courthouse.

Robert Roll, the late judge's son, is also expected to attend.

John Roll was among the six people killed in the mass shooting in January 2011.

Then-U.S. Rep. Gabrielle Giffords and 12 others were wounded in the attack.

Roll served as chief federal judge in Arizona.

Roll had signed off on the design of new courthouse days before his death, a project he considered his top priority for several years to make a reality.

The $25 million courthouse includes two courtrooms, judges' chambers, detention cells and other court-related offices.
