Reports reveal details in Tucson shooting
Authorities in Arizona have released thousands of pages of documents in the case against the man convicted in the 2011 Tucson shooting rampage.
Nearly 3,000 pages of records from the investigation were in the custody of the Pima County Sheriff’s Office, and had been kept private for two years.
The records show Jared Loughner was polite and cooperative while police questioned him for hours. According to the documents, Loughner also complained of feeling sore. At one point he told investigators he was "about ready to fall over."
In November, Loughner was sentenced to life in federal prison for killing six people and severely wounding former Congresswoman Gabrielle Giffords outside a Tucson grocery store.
A judge allowed the documents’ release at the end of the criminal case against him.
