Jared Loughner, the Tuscon, Arizona shooter who killed six people and injured then-Representative Gabrielle Giffords, is expected to plead guilty in court on Tuesday, sources told the Los Angeles Times and the Wall Street Journal this weekend.
Loughner, who opened fire at a meet-and-greet event for Giffords at a supermarket on January 8, 2011, was deemed psychologically unfit to stand trial in May 2011.
However, the 23-year-old has been undergoing treatment, and his doctors say he's mentally competent to offer the plea, NBC News reported.
The US Attorney's Office would not confirm or deny reports that Loughner, a diagnosed schizophrenic, will plead guilty to last year's shooting, which injured 13 people, including Giffords, who was shot in the head, CNN reported.
The democratic representative for Arizona resigned from her seat in congress January 25 to focus on her recovery, and has been improving slowly since the accident, UPI reported.

"I can neither confirm or deny the reports in the LA Times and other media about the Loughner case," Bill Solomon, spokesman for the US Attorney's Office in Arizona, told CNN when asked about the reports.
He said there were no comments on the case planned for Monday.
Though Loughner's condition has been improving, his lawyers have fought the government's attempts to administer him medication for schizophrenia, the Associated Press reported. Though a federal appeals court allowed the shooter to stop taking medicine, Loughner began taking it again when mental health experts at the prison reported that his condition was deteriorating.
Loughner was removed from the court hearing where he was deemed mentally unfit on May 25, 2011 after going on a loud rant.
Legal sources told NBC News that plea agreement terms are still being discussed.
It remains unclear whether Loughner will plead guilty to all the charges in the federal indictment or only some of them.
