On May 25, 2011, the US District Court for the District of Arizona ruled that accused shooter Jared Lee Loughner was not competent to stand trial due to mental illness. The decision was based on reports that Loughner was schizophrenic. He was charged with the shooting death of Chief Judge John Roll of the US District Court for the District of Arizona and five other people, as well as wounding fourteen others including US Representative Gabrielle Giffords. Though Loughner invoked his right to remain silent and refused to talk to investigators, he was indicted by a federal grand jury on January 20, 2011. Additional charges were also filed against Loughner in March 2011.
