President Obama signed a law Thursday naming a new courthouse after Federal Judge John M. Roll in Yuma, Arizona.
Judge Roll and Representative Gabrielle Giffords worked to get funding for the new federal courthouse in Yuma. He also approved the design for the building shortly before his death.
And Christina Taylor Green will have a baseball field named after her where she played second base for her Little League team. Her family is expected to throw out the first pitch when the season begins April 1.
A park will also be named after the 9-year-old in Pima County, where Tuscon is located.
Roll and Green are among the six people killed in the shootings that wounded Rep. Giffords and 13 others.
The suspect in the shooting, Jared Loughner, has pleaded not guilty to federal charges in the case.
