AZ suspect Jared Loughner on suicide watch

PHOENIX

A newly released court filing also said prison staff reported /*Loughner*/ has been pacing in circles near is cell door, screaming loudly, crying for hours at a time and claiming to hear messages from a radio.

Loughner, 22, has been in federal prison in Missouri since May after a federal judge concluded he was mentally unfit to help in his legal defense.

He pleaded not guilty in the January shooting that killed six people and wounded 13 others including U.S. Rep. Gabrielle Giffords.
