PHOENIX (AP) -- New court documents say the Tucson shooting rampage suspect was put on a 24-hour suicide watch at a federal prison in Missouri after he asked a staff psychologist to kill him.
A 24-page filing by federal prosecutors also says Jared Lee Loughner has been pacing in his cell, crying for hours at a time and claiming to hear messages from a radio.
The 9th Circuit Court of Appeals has denied an emergency motion by defense lawyers to keep prison officials from forcibly medicating Loughner with a psychotropic drug.
Loughner has pleaded not guilty to 49 charges in the January shooting that killed six people and wounded 13 others, including U.S. Rep. Gabrielle Giffords.
He's been at the Missouri facility since May 27 after being judged mentally unfit to stand trial.
