Congresswoman’s alleged shooter set to plead guilty

Jared Loughner, the man accused of killing six people and wounding then-US congresswoman Gabrielle Giffords in 2011, is set to plead guilty in a Tucson court tomorrow, a person familiar with the case said.

The source confirmed the federal government believed Mr Loughner was now competent to stand trial and will argue that in court tomorrow.

Mr Loughner is willing to change his plea to guilty at the previously scheduled hearing, the source said.
