The man who killed six people and injured 13 others, including former US Congresswoman Gabrielle Giffords, in Tucson, Arizona, last year is expected to plead guilty to charges against him, The Los Angeles Times reported on Saturday.
Citing "knowledgeable sources," the newspaper said Jared Lee Loughner was likely to enter the guilty plea at a hearing in US district court in Tucson early Tuesday.
Loughner has been charged in connection with the bloodbath outside a Tucson supermarket where Giffords, a Democrat, was meeting with constituents.
Among the six dead were a federal judge, a nine-year-old girl and a member of the congresswoman's staff.
In January 41-year-old Giffords -- who had been seen as a rising star in the Democratic Party -- resigned to focus on her remarkable but continuing recovery.
According to The Times, mental health officials now believe Loughner is now competent enough to understand the charges against him.
